JP7705665B2 - Aerosol type color shampoo composition - Google Patents

Description

The present invention relates to an aerosol type color shampoo composition filled with carbon dioxide gas or other propellants.

Hair dye compositions can be broadly divided into permanent hair dyes that use oxidative dyes, semi-permanent hair dyes that use direct dyes such as hair manicures, and temporary hair dyes that use pigments such as color sprays, which temporarily dye the hair. Oxidative hair dyes, which are a type of permanent hair dye, use an alkaline agent such as ammonia and an oxidizing agent such as hydrogen peroxide along with an oxidative dye, and therefore have higher dyeing properties than semi-permanent hair dyes. However, the alkaline agent generated during use can cause discomfort to the user, and the need to repeatedly apply the oxidizing agent can cause lipids such as sterols, ceramides, and anteiso branched fatty acids present in the hair to be lost during chemical treatments such as hair dyeing, which can damage the hair.

On the other hand, temporary hair dyes also contain resins to adhere the pigment to the hair, and many of them can make the hair sticky and stiff when used, which can be unpleasant for users.

Cream-type hair dye compositions are widely known as common hair dye compositions, but in most cases, the preparation is tedious, and it is not easy to apply it evenly to the hair without staining clothes. In particular, applying it thoroughly to the roots on the inside of the hair and to the back of the head requires specialized skills and a lot of time.

Color shampoo is a type of semi-permanent hair dye that dyes hair by absorbing basic dyes or hair color dyes into the hair through repeated use, gradually changing the color tone of the hair. Since it can be used to wash and dye hair at the same time, it allows you to easily dye your hair little by little as part of your daily hair washing routine, and has the effect of complementing the browning caused by daily washing and maintaining the color tone of your hair.

On the other hand, carbonated shampoos, which contain carbon dioxide as a propellant in the shampoo composition, are known as shampoo compositions that can thoroughly cleanse dirt in pores that cannot be removed by washing with a normal shampoo, by adsorbing and lifting sebum dirt on the hair and scalp with fine carbonated bubbles, as well as soften scalp that has become hard due to dryness, etc., and maintain the scalp in a healthy state by penetrating beauty ingredients into the stratum corneum.

Therefore, by including carbon dioxide in the color shampoo composition, it is thought that it will be easier to distribute the hair dye ingredients evenly to the roots and back of the head, improving both the hair dyeing power and the hair washing power.

Patent No. 6564603

However, in order to eject a shampoo composition containing carbonated water in the form of foam, it is necessary to fill and store the composition in a metal can or the like. In the case of a color shampoo composition, there is a risk that chloride ions generated when the conditioning component and hair dye component in the composition are mixed together may corrode the can, and therefore conventional carbonated color shampoos are unable to provide sufficient hair dyeing effects.

Therefore, the objective of the present invention is to provide a color shampoo composition containing carbon dioxide that has sufficient hair dyeing and washing power while suppressing the generation of chloride ions to a certain range.

In this regard, the inventors of the present invention have discovered that the generation of chloride ions can be suppressed by adjusting the blend ratio of the conditioning agent and hair dye.

In order to solve the above problems, the present invention provides a color shampoo composition that contains (A) polyquaternium-10 as a conditioning component, (B) at least one hair dye component selected from HC Yellow 4, 4-hydroxypropylamino-3-nitrophenol, HC Blue 2, Basic Blue 75, Basic Brown 16, Basic Red 51, Basic Yellow 87, and Basic Blue 99, (C) at least one surfactant selected from cocamidopropyl betaine, sodium laureth-4 carboxylate, hydroxyalkyl (C12-14) hydroxyethyl sarcosine, sodium dilauroyl glutamate lysine, sodium lauroyl methylalanine, TEA-cocoyl glutamate, and lauramide DEA, and (D) water, and the chloride ion concentration contained in (A) to (D) is in the range of 1500 ppm to 10,000 ppm.

The present invention, which has such a configuration, can suppress the generation of chloride ions to a certain concentration by mixing the conditioning component and the hair dye component at a certain ratio, so that the significant hair dyeing and conditioning properties of a color shampoo are maintained, and when this is filled into an aerosol can with carbon dioxide gas as a propellant, the metal parts that come into contact with the color shampoo composition are not corroded and the condition can be safely maintained.

The carbonated color shampoo of the present invention uses a gas injection method to eject the color shampoo composition filled in an aerosol can, which produces finer bubbles than conventional ones that have excellent adsorption power and can easily and evenly dye even gray hair at the roots.

In addition, it thoroughly absorbs oily dirt from pores and lifts it to the surface, and the elasticity of the foam acts as a cushion between the hair/scalp and your fingers, reducing friction damage caused by washing your hair and minimizing damage to your hair and scalp.

This allows users to not only thoroughly remove oily dirt from the scalp through daily hair washing, but also to safely and easily color their hair to the desired tone without losing its elasticity and strength.

One embodiment of the color shampoo composition containing carbon dioxide gas of the present invention is described below.

The carbonated color shampoo of the present invention contains a conditioning component, a hair dye component, a surfactant, and water.

In this embodiment, 0.1% by weight of polyquaternium-10 and a very small amount of hydroxypropyltrimonium hyaluronate are added as conditioning ingredients.

The hair dye ingredients used are one or more of HC Yellow 4, 4-hydroxypropylamino-3-nitrophenol, HC Blue 2, Basic Blue 75, Basic Brown 16, Basic Red 51, Basic Yellow 87, and Basic Blue 99.

To achieve a black hair dye, 0.375% by weight of HC Yellow 4, 0.02% by weight of 4-hydroxypropylamino-3-nitrophenol, 1% by weight of HC Blue 2, 0.02% by weight of Basic Blue 75, 0.12% by weight of Basic Brown 16, 0.002% by weight of Basic Red 51, 0.075% by weight of Basic Yellow 87, and 0.36% by weight of Basic Blue 99 are blended.

To achieve a dark brown hair dye, the mixture can be formulated as follows: 0.404% by weight of HC Yellow 4, 0.104% by weight of 4-hydroxypropylamino-3-nitrophenol, 0.9% by weight of HC Blue 2, 0.068% by weight of Basic Blue 75, 0.195% by weight of Basic Brown 16, 0.023% by weight of Basic Red 51, 0.045% by weight of Basic Yellow 87, and 0% by weight of Basic Blue 99.

It was found that by adjusting the mixing ratio of the conditioning ingredients to the hair dye ingredients to within the range of 1:5.79 to 1:19.7, the concentration of chloride ions generated fell within the range of 1,500 ppm to 10,000 ppm.

This makes it possible to maintain and manage the color shampoo composition in the can for more than six months without losing its conditioning properties and without corroding the aerosol can. It has also been confirmed that the gas spray method using the aerosol can produces finer bubbles than before, resulting in a significant improvement in hair dyeing and washing power.

In particular, while conventional carbonated shampoos generally contain bubbles with a diameter of about 1000 μm, the aerosol color shampoo composition of the present invention can produce delicate and dense bubbles of about 300 μm, which are created from a high concentration of carbon dioxide of about 5000 ppm. The fine, adhesive bubbles not only absorb oily dirt from pores and dye hair evenly and neatly, even to the roots of gray hair, but also provide the effect of reducing friction and preventing damage to the hair and scalp by acting as a cushion between the hair/scalp and fingers.

The moisture content is preferably between 57 and 85% by weight, taking into account the overall balance.

Compared to regular shampoos, carbonated shampoos have a fine foam that is inherent in the composition when used, and they are characterized by being able to thoroughly remove dirt that is difficult to remove with regular shampoos by absorbing and lifting up sebum dirt and oily ingredients contained in hair styling products that are clogged in the pores of the hair and scalp.

Carbon dioxide gas not only removes dirt, but has also been shown to soften the scalp, and has the added benefit of softening the skin, making it easier for beauty ingredients to penetrate the stratum corneum, particularly on dry, hard scalps.

As a result, there are concerns about damage to the scalp, particularly when it comes to shampoos containing hair dye ingredients. If they can be used in a state that contains a high concentration of carbon dioxide gas, it will soften the scalp while allowing the beauty ingredients contained in the composition to penetrate to every corner of the stratum corneum, helping to maintain a healthy scalp.

In this regard, in this embodiment, the following ingredients are also used: Lisilis extract, tea leaf extract, Pinus sylvestris cone extract, red clover flower extract, Quillaja japonica bark extract, Sapindus mukorossi peel extract, persimmon tannin, Swertia japonica extract, Bidens pilosa extract, Panax ginseng root extract, royal jelly extract, Gentiana root extract, Watercress leaf extract, Yuzu fruit extract, Placenta extract, Burdock root extract, Tilia cordata flower extract, Althea root extract It contains 30 types of beauty ingredients, including arnica flower extract, oleander leaf extract, white lamb's foot extract, chamomile flower extract, artemisia capillaris flower extract, English ivy leaf extract, peony extract, rosemary leaf extract, Roman chamomile flower extract, okra fruit extract, purple root extract, and turmeric rhizome extract, as well as scalp extract and Rishiri kelp extract, which penetrate into the stratum corneum and help maintain moisture and help retain and hydrate the skin.

However, as mentioned above, when the conditioning ingredients polyquaternium-10 and hydroxypropyltrimonium hyaluronate are mixed with hair dye ingredients that are said to be basic, a certain concentration of chloride ions is generated, which corrode the spray can used to fill with carbon dioxide, making it impossible to safely maintain, manage, or use the composition.

In this regard, although there may be some variation depending on the color combination, in order to maintain sufficient conditioning properties and stabilize the chloride ion concentration in the composition at approximately 1,500 ppm to 10,000 ppm, it is necessary to devise and adjust the combination of surfactants and their blending ratios while limiting the blending of polyquaternium-10.

Surfactants include anionic surfactants, cationic surfactants, amphoteric surfactants, and nonionic surfactants, and anionic surfactants and amphoteric surfactants are generally used in shampoos. The aerosol type color shampoo composition of the present invention contains the following surfactants: cocamidopropyl betaine (coconut oil fatty acid amidopropyl betaine solution): 5.89% by weight, sodium laureth-4 carboxylate: 3.6% by weight, hydroxyalkyl (C12-14) hydroxyethyl sarcosine: 1.35% by weight, sodium dilauroyl glutamate lysine: 0.029% by weight, sodium lauroyl methylalanine: 0.6% by weight, TEA-cocoyl glutamate: 0.15% by weight, and lauramide DEA: 0.1% by weight.

This has the effect of creating a more elastic foam.

In addition, to suppress the inclusion of basic hair dye ingredients, hair dye ingredients such as HC Yellow 4, 4-hydroxypropylamino-3-nitrophenol, and HC Blue 2 are included to supplement the dyeing performance. In this example, no additives such as parabens, petroleum-based surfactants, silicone, synthetic colorants, mineral oils, or sulfate compounds are added.

(Method of evaluating hair dyeability)
A bundle of white hair (1 g, 10 cm) was immersed for 5 minutes in large bubbles made by normal use and in small bubbles made by the aerosol method according to the present invention, then rinsed with water, dried, and measured using a color difference meter.

When dyeing hair with large bubbles, L* was 22.11. On the other hand, when dyeing hair with small aerosol bubbles, L* was 23.54, which is a measurement result of about 6.5% increase in dyeing power. (Table 2)

Table 1 shows the results of a test conducted by five panelists on color shampoos that had different ratios of conditioning ingredients and hair dye ingredients.

(Conditioning properties)
The results showed that hair that contained conditioning ingredients felt smoother to the touch after drying.

(stability)
If too much hair dye ingredient was added to the composition, crystal precipitation was observed.

As described above, the present invention is capable of suppressing the generation of chloride ions to a certain concentration by mixing the conditioning component and the hair dye component at a certain blending ratio, and therefore, while maintaining significant hair dyeing and conditioning properties as a color shampoo, when this is filled into an aerosol can with carbon dioxide gas as a propellant, the metal parts that come into contact with the color shampoo composition are not corroded, and the state can be safely maintained. The color shampoo composition filled into an aerosol can is discharged by a gas injection method, and the high concentration of carbon dioxide gas forms finer bubbles than before, which have excellent adsorption power and adhere to the white hair at the roots. In addition to being able to easily and evenly dye hair, it also evenly adsorbs and lifts oily dirt from pores, and the elasticity of the foam acts as a cushion between the hair/scalp and fingers, reducing friction damage caused by washing the hair and minimizing damage to the hair and scalp. This not only allows the user to fully remove oily dirt from the scalp during daily hair washing, but also enables the user to safely and easily color the hair to the desired color without losing its firmness and strength, making it extremely suitable for use in an aerosol color shampoo composition.
