JP4675280B2 - Hair conditioning composition - Google Patents

Description

  The present invention relates to a hair conditioning composition that prevents hair from peeling off the cuticle and that can impart softness, ease of uniting, and suppleness.

  Examples of hair cosmetics that have conditioning effects such as imparting smoothness and gloss to the hair and improving the combing are hair rinses, hair treatments, hair packs, and the like. In these hair cosmetics, a quaternary ammonium salt is blended as a main component, and higher alcohol, liquid paraffin, ester oil and the like are blended to further improve the conditioning effect. It is known that the conditioning effects described above can be obtained when these components adhere to the hair.

For example, hair cosmetics (for example, see Patent Document 1) containing a specific amount of a mixed component in which a cationic surfactant and a higher alcohol are combined in a specific ratio and a low-viscosity oil component are disclosed. Has been shown to give excellent smoothness and a non-sticky feel.
Moreover, the hair rinse composition (for example, refer patent document 2) containing a cationic surfactant and a specific paste oil agent is disclosed, and it is shown that they suppress the roughness of hair and give a unity.
Moreover, hair cosmetics (for example, see Patent Document 3) in which an amidoamine compound, a fatty acid, an organic acid and a highly polymerized dimethylpolysiloxane are combined are disclosed, and are proposed to impart smoothness, flexibility, and gloss. ing.
Furthermore, the applicant of the present application has applied for an invention (see Patent Document 4) of an anti-fading composition comprising a combination of a high-polymerized siloxane compound and a low-polymerized siloxane compound to reduce the fading of hair that has been dyed by washing or the like. At the same time, it is disclosed that there is an effect of imparting ease of grouping, suppleness, combing and gloss.

All of the above conventional techniques have been improved as a hair conditioning composition. For example, with dimethicone that has been used in the past, effects such as prevention of exfoliation of cuticles existing on the surface of the hair and prevention of hair roughness. However, satisfactory characteristics cannot be obtained sufficiently.
Therefore, the purpose of the present invention is to prevent hair cuticle peeling without reducing the advantages of conventional compositions, to suppress the roughness, further enhance the suppleness imparting effect, and even after a long time after washing the hair, An object of the present invention is to provide a hair conditioning composition that maintains these effects and is excellent in softness and unity of hair.

  As a result of diligent research to achieve the above-mentioned objectives, by limiting the polymerization degree and mass ratio of dimethiconol to the above-mentioned problems that could not be obtained with dimethicone, it was possible to reduce the gloss, burr, and lack of stiffness of split ends and hair. It has been found that it is possible to prevent the exfoliation of the cuticle, which is also the cause, and to give softness, ease of grouping and suppleness.

That is, claim 1 of the present invention includes (A) dimethiconol having a kinematic viscosity at 25 ° C. of 5,000 mm ² / s or less represented by the following general formula (1) and (B) a kinematic viscosity at 25 ° C. of 100,000 mm A hair conditioning composition comprising ² / s or more of dimethiconol and (C) sodium glutamate, and further containing a mass ratio of (A) to (B) of 2: 3 to 1: 8. is there.

[N represents an integer]

The hair conditioning composition according to claim 1, wherein (A) and / or (B) is preliminarily formulated as an aqueous emulsion, and claim 3 according to the present invention comprises: The hair conditioning composition according to claim 1, wherein the mixture of (A) and (B) is blended in advance as an aqueous emulsion, and claim 4 of the present invention further has a pH of 5. It is 0-7.0, The hair conditioning composition in any one of Claims 1-3 characterized by the above-mentioned.

The hair conditioning composition of the present invention can prevent cuticle peeling of hair, and can further impart softness, ease of grouping, and flexibility.

Hereinafter, the configuration of the present invention will be described in detail.
In the dimethiconol represented by the following general formula (1) used in the components (A) and (B) of the present invention, the component (A) is dimethiconol having a kinematic viscosity at 25 ° C. of 5,000 mm ² / s or less. Dimethiconol having a kinematic viscosity at 25 ° C. of 1,000 mm ² / s or less is preferable, and dimethiconol having a kinematic viscosity at 25 ° C. of 200 mm ² / s or less is more preferable. Component (B) as a dimethiconol kinematic viscosity is more than 100,000 mm ² / s at 25 ° C. is preferably dimethiconol kinematic viscosity of more than 500,000 ² / s at 25 ° C., more preferably a kinematic viscosity at 25 ° C. Is a dimethiconol of 1,000,000 mm ² / s or more.

[N represents an integer]

  The mass ratio of the component (A) to the component (B) is 2: 3 to 1: 8, more preferably 2: 3 to 1: 6, and particularly preferably 2: 3 to 1: 4. When the component (A) is blended in a large amount exceeding the ratio of component (A): component (B) = 2: 3, the effect of preventing the anti-cuticle release intended by the present invention is not sufficiently exhibited, and the component (B ) Exceeds the ratio of component (A): component (B) = 1: 8, it is not preferable because it causes a feeling of stiffness after drying.

Moreover, it is preferable that these dimethiconols mix | blend each (A) and (B) as an aqueous emulsion previously, or mix | blend what the mixture of (A) and (B) made the aqueous emulsion previously.
These emulsions used in the present invention can be made in various ways, and these methods are well known. For example, it can be produced by polymerizing by mechanical high shear mixing of silicone and water, or by emulsifying silicone with water and an emulsifier, or by a combination of mechanical polymerization and emulsion polymerization. Among these, creation by mechanical polymerization is preferable in terms of imparting a good feel.

The content of components (A) and (B), dimethiconol, is the hair treatment composition of the present invention in terms of preventing cuticle peeling of hair, imparting softness and suppleness. 0.01 to 20.0 mass% of the product, particularly 0.1 to 10.0 mass% is preferable. If it is less than 0.01% by mass, the object of the present invention may not sufficiently exert the effect of preventing the peeling of the cuticle, and if it exceeds 10.0% by mass, a sticky feeling may occur after drying.

  In the present invention, (C) sodium glutamate can improve the feel of cuticle peeling of hair, softness, ease of uniting, suppleness and the like.

The content of (C) sodium glutamate in the hair conditioning composition is preferably 0.5 to 5.0 mass%, more preferably 0.5 to 1.5 mass%. When the content is less than 0.5% by mass, the effect may not be sufficiently exhibited. When the content is more than 5.0% by mass, the stability of the preparation or the touch is felt. Inconvenience may occur.

  The pH at 25 ° C. of the hair conditioning composition of the present invention is preferably in the range of 5.0 to 7.0, more preferably 5.5 to 6.5 from the viewpoint of good feel. When the pH is less than 5.0, a good feel cannot be obtained, and when the pH exceeds 7.0, the stability of the preparation is poor.

The composition of the present invention is a hair conditioning composition used for washing out hair shampoos, hair rinses, hair treatments, hair packs, etc., or a hair conditioning composition used for out baths such as hair essences, hair creams, hair foams, hair sprays, etc. Used as These are used in various dosage forms such as liquid, cream, paste, foam, mist, and powder.

  In the hair treatment composition of the present invention, in addition to the essential components described above, optional components that are usually used can be used as long as they do not impair the effects of the present invention. These components include anionic surfactants, cationic surfactants, nonionic surfactants, oils, UV absorbers, preservatives, moisturizers, polymers, amino acid derivatives, sugar derivatives, perfumes, water, Examples include alcohol, thickener, colorant, sequestering agent, antioxidant, and drug.
