JP7700166B2 - Oil-in-water sunscreen cosmetics - Google Patents

Description

The present invention relates to an oil-in-water sunscreen cosmetic, and more specifically, to an oil-in-water sunscreen cosmetic that contains specific ingredients, which provides excellent secondary adhesion resistance and makeup application, and is free of dryness, squeaking, or stickiness, and is free of stability problems such as aggregation and precipitation.

Protecting the skin from the harmful effects of ultraviolet rays is an important issue in skin care and body care. The purpose of sunscreen cosmetics is to protect the skin from ultraviolet rays and minimize their adverse effects on the skin. Generally, sunscreen cosmetics combine ultraviolet absorbing agents and ultraviolet scattering agents to provide a high level of ultraviolet protection (Non-Patent Document 1).

Sunscreen cosmetics are typically formulated as oil-in-water or water-in-oil emulsions. In recent years, there has been an increasing demand for sunscreen formulations that have a high SPF (Sun Protection Factor) value but also have a refreshing feel when used, so that they can be used like skin care, and oil-in-water sunscreen formulations are particularly widely used.

However, compared to water-in-oil emulsion cosmetics, oil-in-water emulsion cosmetics tend to form uneven coatings and have inferior coating resistance, so when aiming for a high SPF value, it is necessary to incorporate larger amounts of UV absorbers and UV scattering agents. Incorporation of these agents in large amounts can lead to skin irritation and cause problems such as poor usability, such as a squeaky feeling or stickiness (Patent Document 1).

Furthermore, when a large amount of UV absorber or UV scattering agent is added to an oil-in-water emulsion cosmetic, which has a lower oil content than a water-in-oil emulsion cosmetic, not only is it difficult to maintain emulsion stability, but there are also issues such as stability problems such as precipitation of the UV absorber and aggregation of the UV scattering agent over time.

Generally, UV absorbers are poorly soluble in water, and in order to incorporate them in formulations at high concentrations, it is necessary to consider their solubility stability. It is known that a highly polar oil, which has good solubility in UV absorbers, can be used to increase solubility stability. For example, diisopropyl sebacate is used, but in order to incorporate these highly polar oils in oil-in-water emulsions at high concentrations, a large amount of surfactant must be incorporated, resulting in issues with the feel of the product when in use, such as stickiness and oiliness.

In addition, in order to provide a high UV protection effect, it is necessary to add an UV scattering agent. Metal oxides such as titanium oxide, zinc oxide, iron oxide, and cerium oxide are generally used as UV scattering agents. In order to stabilize the formulation by adding these UV scattering agents, it is necessary to add oils and dispersants with good dispersibility. However, if an oil that inhibits the solubility of the UV absorber is added, poor stability such as precipitation occurs when used in combination with the UV absorber. Therefore, a material that can achieve both dispersion stability and dissolution stability must be selected. For example, the previously mentioned diisopropyl sebacate is a solvent that has excellent solubility for UV absorbers, but the results regarding the dispersibility of UV scattering agents were not satisfactory. If the dispersion of the UV scattering agent becomes poor, not only does the formulation stability deteriorate, but the feeling of squeaking and stickiness also worsen, so it is essential to achieve both.

As a conventional technique, for example, a technique has been reported in which a volatile hydrocarbon or isostearic acid is used to stably disperse an ultraviolet scattering agent in an oil phase (Patent Document 2). However, since the ultraviolet absorbers used contain a large amount of liquid components and do not contain a poorly soluble ultraviolet absorber, it cannot be said that both the aggregation stability of the ultraviolet absorber and the dispersion stability of the ultraviolet scattering agent are achieved.

The term "makeup adhesion" refers to whether or not a makeup cosmetic blends well with the skin. Having good makeup adhesion means that the makeup cosmetic can be spread evenly on the skin and that the finished skin looks beautiful. Generally, makeup-lasting effects are imparted as the effect of a makeup base (Patent Document 3), but the makeup-lasting effect is a technology related to the persistence of makeup and relates to functions such as resistance to sweat and sebum. The makeup adhesion effect of the present application does not refer to an effect related to persistence, but refers to the instantly felt finish of the makeup cosmetic and the effect of being able to spread evenly.
In recent years, the demand for cosmetics that provide excellent makeup application has been growing due to consumers' increasing awareness of beauty. In addition, the need to use sunscreen as a substitute for makeup base has also increased due to consumers' awareness of time saving and the growing demand for sunscreen effects. Therefore, in recent years, there has been a demand for the development of sunscreen cosmetics that provide excellent makeup application effects.

Many of the techniques for improving the adhesion of makeup are generally formulation techniques for improving rough skin. For example, a formulation combining 1-acyl-2,3-cyclic phosphatidic acid or its salt, which is an ingredient for inhibiting skin aging, and polyoxyethylene methyl glucoside with a specific average added mole number of ethylene oxide in a specific ratio was used for one week, and the results showed that it improved the adhesion of makeup (Patent Document 4).
Furthermore, it has been reported that an emulsion composition containing sphingosine, a salt of sphingosine, a pseudosphingosine, a salt of pseudosphingosine, one or more compounds selected from an anionic surfactant and a cationic surfactant, ceramides, a glycerol fatty acid ester, a higher alcohol, and a polymer in a specific mass ratio, the polymer having a light transmittance of 90% or more when measured at 25°C after mixing 25 parts by mass per 100 parts by mass of cetanol at 85°C and having a main chain glass transition temperature Tg of 25°C or less, improves the application of makeup when the area where the composition was used is washed and makeup is applied, even when used continuously for three days (Patent Document 5).
However, none of these products provide an immediate improvement in the application of makeup, and it takes time for the application of makeup base to improve. Since a makeup base is required to provide a beautiful finish for makeup immediately after application, these products did not provide a satisfactory improvement in the application of makeup.

As an example of a sunscreen cosmetic that has improved the makeup application effect, a combination of 1-13% by mass of polysilicone microcapsules with an average particle size of 0.1-10 μm encapsulating an ultraviolet absorber, 0.5-10% by mass of a compound represented by formula (I), and 0.1-1% by mass of a carboxyvinyl polymer or an alkyl-modified carboxyvinyl polymer has been developed (Patent Document 6). However, the makeup application effect is not sufficient, and since it is not used in combination with an ultraviolet scattering agent, the ultraviolet protection effect is also unsatisfactory.

In recent years, due to the background of wearing masks and the viewpoint of the durability of the sunscreen effect, a secondary adhesion-free effect on clothing, etc. is required (Patent Document 7). Secondary adhesion refers to the re-adhesion of the applied sunscreen to clothing, belongings, etc. If secondary adhesion occurs, the UV protection effect and the finish of the cosmetic film may deteriorate, and in recent years, a secondary adhesion-free effect is also required in sunscreens.
As techniques for enhancing the secondary adhesion-free effect, there have been disclosed techniques for imparting quick-drying properties by blending large amounts of components that evaporate at room temperature, such as volatile silicone oils, volatile hydrocarbon oils, volatile hydrofluoroethers, and water, and techniques for combining oil-based film-forming agents such as hard, non-transferable silicone resins (Patent Document 8, Patent Document 9).
However, Patent Documents 8 and 9 are technologies related to water-in-oil type cosmetics, and when the technologies disclosed in them are applied to oil-in-water type cosmetics, a hard film is imparted, which causes a dry feeling and a decrease in moisturizing effect.In addition, the film-forming agent-specific squeaky and sticky feeling occurs, which is not satisfactory in terms of feel when used.

In view of the above, there was an urgent need to develop an oil-in-water sunscreen cosmetic which has an excellent secondary adhesion-free effect and excellent makeup application, and in addition is free of dryness, squeaky feeling, or stickiness, and is free of stability problems such as aggregation and precipitation.

The present invention has been made in view of the above-mentioned conventional techniques, and has an object to provide an oil-in-water sunscreen cosmetic which is excellent in secondary adhesion resistance effect and makeup adhesion, and in addition is free from dryness, squeaking and stickiness, and is free from stability problems such as aggregation and precipitation.

The inventors conducted extensive research to solve the above problems and discovered that by combining the specific ingredients shown below, a sunscreen cosmetic product that can solve the above problems was obtained, leading to the completion of the present invention.

That is, the oil-in-water sunscreen cosmetic of the present invention comprises components (A) to (D).
(A) Isoamyl laurate (B): (B-1) Polyglyceryl-10 (isostearic acid/succinic acid)
and (B-2) polyhydroxystearic acid; (C) an ultraviolet scattering agent; and (D) an ultraviolet absorbing agent.

According to the present invention, it is possible to provide an oil-in-water sunscreen cosmetic which has an excellent secondary adhesion-free effect and excellent makeup adhesion, and in addition is free from dryness, squeaking, and stickiness, and is free from stability problems such as aggregation and precipitation.

The present invention will be described in more detail below. Unless otherwise noted, when the amount of each component is expressed as "%", it means % by mass.

Component (A) isoamyl laurate used in the present invention can be produced by esterification of isopentyl alcohol and lauric acid.

The amount of isoamyl laurate (component (A)) in the oil-in-water sunscreen cosmetic formulation of the present invention is not particularly limited as long as it is within a range in which the effects of the present invention can be obtained, but is usually preferably 1.0% by mass to 20.0% by mass, and more preferably 2.0% by mass to 15.0% by mass, based on the total amount of the cosmetic. Within this range, the secondary adhesion-free effect, makeup adhesion effect, precipitation and aggregation stability, and squeaky and sticky feelings are excellent.

Component (B) used in the present invention is selected from (B-1) polyglyceryl-10 (isostearic acid/succinic acid) and (B-2) polyhydroxystearic acid.

Component (B-1) (isostearic acid/succinic acid) polyglyceryl-10 used in the present invention refers to a compound in which isostearic acid and succinic acid are ester-bonded to the hydroxyl groups of polyglycerin with an average degree of polymerization of glycerin of 10. It is usually used as a powder dispersant. There are no particular restrictions, and any compound usually used in cosmetics can be used.

The component (B-2) polyhydroxystearic acid used in the present invention is a polymer of hydroxystearic acid having one hydroxyl group. In the present invention, in order to improve the dispersion stability of (C), the hydroxyl group of the hydroxystearic acid is preferably at the 12th position, and the average degree of polymerization of the hydroxystearic acid is preferably 3 to 12, and more preferably 4 to 8.

The total amount of component (B) in the oil-in-water sunscreen cosmetic of the present invention is not particularly limited as long as it is within a range in which the effects of the present invention can be obtained, but is usually preferably 0.1 to 5.0% by mass, more preferably 0.3 to 3% by mass, based on the total amount of the cosmetic. Within this range, excellent secondary adhesion prevention effect, makeup adhesion effect, aggregation stability, squeaky feeling and sticky feeling can be achieved.

Either (B-1) or (B-2) may be used alone, or two or more of either may be used, or one or more of each may be used in combination.

The component (C) UV scattering agent used in the present invention is not particularly limited, and those normally used in cosmetics can be used, but hydrophobized metal oxides are preferably used. From the viewpoint of UV protection, it is preferable to use fine particles with an average primary particle diameter of 100 nm or less, measured by using a scanning electron microscope to measure the particle diameter of 10 particles in any field of view. The average primary particle diameter in the present invention can be determined, for example, from image analysis using a transmission electron microscope as the arithmetic mean of the long and short axes of the particles. Particularly preferred metal oxides include titanium oxide, zinc oxide, and cerium oxide. The method of hydrophobization is not particularly limited, and examples of the method include commonly used treatment methods such as coating treatment, baking treatment, and silane coupling agent treatment. The hydrophobization treatment agent is not particularly limited, and metal soaps, silicones, fatty acids, phospholipids, fluorine compounds, silylation agents, and acyl amino acids can be preferably used. In particular, triethoxycaprylylsilane treatment, fatty acid treatment such as isostearic acid, and silicone treatment are suitable from the viewpoint of the stability, water resistance, and cleanability of the composition. The silicone used in the silicone treatment is not particularly limited, but examples include dimethicone and hydrogen dimethicone.

The amount of component (C) UV scattering agent in the oil-in-water sunscreen cosmetic of the present invention is not particularly limited as long as it is within a range in which the effects of the present invention can be obtained, but is usually preferably 3% to 35% by mass, and more preferably 5% to 25% by mass, based on the total amount of the cosmetic. Within this range, the secondary adhesion-free effect, makeup adhesion effect, and aggregation stability are excellent while suppressing the feeling of squeaking.

Component (C) may be used alone or in combination of two or more types.

The component (D) UV absorber used in the present invention is not particularly limited, and any UV absorber commonly used in cosmetics can be used. Preferred UV absorbers include UV absorbers such as octyl methoxycinnamate (ethylhexyl methoxycinnamate), octocrylene, t-butyl methoxydibenzoylmethane, ethylhexyl triazone, diethylamino hydroxybenzoyl hexyl benzoate, oxybenzone-3, methylene bisbenzotriazolyl tetramethylbutylphenol, phenylbenzimidazole sulfonic acid, homosalate, ethylhexyl salicylate, and bisethylhexyloxyphenol methoxyphenyl triazine.

The amount of component (D) UV absorber in the oil-in-water sunscreen cosmetic of the present invention is not particularly limited as long as it is within a range in which the effects of the present invention can be obtained, but it is preferably 0.1% by mass to 25% by mass, and more preferably 1% by mass to 20% by mass, based on the total amount of the cosmetic. Within this range, the cosmetic will have a high makeup adhesion effect and excellent precipitation stability while suppressing stickiness.

Component (D) may be used alone or in a mixture of two or more types.

The volatile hydrocarbon of component (E) used in the present invention is a hydrocarbon that is volatile at room temperature (15 to 25°C). There are no particular limitations as long as it is a volatile hydrocarbon oil that is normally used in cosmetics. Examples of such volatile hydrocarbon oils include paraffinic hydrocarbon oils such as n-decane, n-undecane, and n-dodecane; isoparaffinic hydrocarbon oils such as isodecane, isododecane, and hydrogenated polyisobutene; and cyclic paraffinic hydrocarbon oils such as cyclodecane and cyclododecane. Among these, hydrogenated polyisobutene is preferred from the viewpoint of improving dispersion stability and usability.

The amount of volatile hydrocarbons (component (E)) in the oil-in-water sunscreen cosmetic formulation of the present invention is not particularly limited as long as it is within a range in which the effects of the present invention can be obtained, but is usually preferably 1.0% by mass to 20.0% by mass, and more preferably 2.0% by mass to 15.0% by mass, based on the total amount of the cosmetic. Within this range, the formulation has a high secondary adhesion resistance effect and excellent makeup adhesion effect while suppressing stickiness.

Component (E) may be used alone or in a mixture of two or more types.

The oil-in-water sunscreen cosmetic of the present invention can take various water-containing formulations, such as lotion, emulsion, gel, and cream.

When applying the oil-in-water sunscreen cosmetic of the present invention to the skin, the cosmetic can be applied directly to the skin, or the skin can be wiped with an absorbent material such as a nonwoven fabric that has been impregnated with the cosmetic.

In addition to the above essential components, the oil-in-water sunscreen cosmetic of the present invention can also contain components that are generally used in cosmetics, etc., as necessary. For example, additives such as dispersants other than component B, powders other than component C, pearlescent agents, moisturizers, water-soluble polymers, fragrances, bactericides, preservatives, antioxidants, pH adjusters, chelating agents, anti-inflammatory agents, antioxidants, cooling agents, herbal extracts, and vitamins can be added as appropriate. The blending ratio of these components when they are added can be appropriately selected depending on their types and purposes, and one type may be used alone, or two or more types may be used in appropriate combination.

The present invention will be further explained below with reference to examples. Note that these examples do not limit the present invention in any way.

[Examples 1 to 14 and Comparative Examples 1 to 7]
Sunscreen cosmetics were prepared in a conventional manner using the components shown in Table 1 and were evaluated by the following methods. The results are shown in Table 1.

<Evaluation method for secondary adhesion resistance>
Samples were prepared according to the SPF measurement method specified in ISO-24444. 2 mg/cm2 of the composition was uniformly applied to Helioplate HD6 (HELIOPLATE (registered trademark) HD6, manufactured by HelioScreen Lab., plate size: 5 cm x 5 cm, material: ^PMMA ), and the SPF value was measured using an SPF analyzer UV-2000S (manufactured by Sanyo Trading Co., Ltd.). Next, the plate on which the sample was prepared was placed on tissue paper with the coated side facing down, and a load of 500 g was placed on the plate for 10 minutes to adhere to the tissue paper, after which the tissue paper was peeled off and the SPF value was measured again. The percentage of the SPF value after peeling off the tissue paper relative to the original SPF value was calculated, and this value was taken as the remaining rate (%).

2 points: No dryness is felt.
1 point: A slight feeling of dryness.
0 points: If you feel dryness.

The total scores of the 20 participants were calculated and judged as follows:
⊚: The total score is 35 points or more. : The cosmetic does not feel dry at all.
A: The total score is 25 points or more and less than 35 points. : The cosmetic does not feel dry.
Δ: The total score is 10 or more and less than 25 points. : The cosmetic product feels slightly dry.
×: The total score is less than 10 points. : The cosmetic product feels very dry.

<Evaluation of stability (aggregation)>
The formulation was filled in an amount of 30 g in a transparent PET container (30 ml) and allowed to stand at 40° C. for one month, after which a skilled technician visually evaluated the composition.
(Evaluation Criteria)
⊚: No aggregation occurs at all.
◯: Almost no aggregation occurs.
△: A small amount of aggregation occurred.
x: Aggregation is evident.

<Evaluation of stability (precipitation)>
The formulation was filled in an amount of 30 g in a transparent PET container (30 ml) and allowed to stand at 40° C. for one month, after which a skilled technician visually evaluated the composition.
(Evaluation Criteria)
⊚: No precipitation occurred at all.
◯: Almost no precipitation occurred.
Δ: slight precipitation occurred.
x: Precipitation is noticeable.

The oil-in-water sunscreen cosmetic of the present invention (Examples 1 to 14) had excellent secondary adhesion-free effect and makeup application, and in addition, there was no dryness, squeaky feeling, or stickiness, and good results were obtained in all aspects, including stability against aggregation and precipitation. In addition, it was confirmed that makeup application was improved even when a different foundation was used. Examples 13 to 14 are examples in which component E was replaced with a similar component, but when component E was replaced, the secondary adhesion-free effect, makeup application, squeaky feeling, sticky feeling, and aggregation stability tended to be slightly inferior, and it was found that volatile hydrocarbons are more preferable for component E in order to achieve the objective of the present application. Comparative Examples 1 to 3 are examples in which component A was not blended or was replaced with a similar component, but when component A was replaced, the makeup application, secondary adhesion-free effect, squeaky feeling, sticky feeling, dryness, and precipitation stability tended to be significantly worse, and the objective of the present application could not be achieved. In Comparative Examples 4 to 7, component B was not used or was replaced with a similar component, but when component B was replaced, the makeup adhesion and secondary adhesion resistance effect deteriorated, and there was a tendency for the feeling of squeaking, stickiness, dryness, and deposition stability to deteriorate. From the above results, it can be seen that the oil-in-water sunscreen cosmetic composition of the present application can achieve all of the objectives of the present application, and a new oil-in-water sunscreen cosmetic composition can be provided that is endowed with functions that could not be achieved with conventional component compositions.
