Description

TECHNICAL FIELD The present invention relates to a hair cosmetic composition that reduces waviness of hair and further reduces recurrence of waviness due to combing, and that is excellent in the effects of finger passage, cohesion, and gloss.

Various problems occur on hair due to chemical damage such as hair dyeing, perm, and straightening of hair, and changes in the hair quality itself caused by aging. For example, with increasing age, waviness, habits, and dullness of wavy hair increase, which causes the hair to become loose and the luster of the entire hair to worsen, as well as chemical damage such as dyeing and bleaching of the hair, heat and heat. It is well known that waviness increases due to physical damage such as friction.

As a technique to improve these, in the type of hair cosmetics such as shampoo, hair rinse, hair treatment, etc., which is used after washing off, cationic polymers, silicones, oils, sugars, etc. should be added to bring out the hardness and weight of the hair. Has attempted to correct the undulations that occur on the hair. However, although these techniques provide hardness and weight to the hair, they cannot be said to sufficiently suppress undulations, and they are also sufficiently effective in suppressing the generation of undulations due to friction damage due to combing or the like. Absent.

As a method for solving this problem, for example, a hair cosmetic (for example, refer to Patent Document 1) in which hair swelling is improved by a specific amidoamine to maintain cohesion, lecithin, an amphoteric surfactant, a film-forming polymer, and a cation. Hair cosmetics containing a polymer (see, for example, Patent Document 2) have been disclosed, but they have not been satisfactory in terms of the effect of suppressing swelling.

In order to solve the above problems, the present inventor has found that a hair cosmetic composition containing hydroxypropyl cellulose, polyethylene glycol, polyhydric alcohol, and ginger tincture, and having a water content of 1% by mass or less (see Patent Document 3). ) Is proposed. However, even in the above hair cosmetics, it cannot be said that the swelling and spreading caused by repeated friction due to combing have a sufficient swelling suppressing effect, and further improvement in the technique has been demanded.

According to the present invention, it is possible to provide a hair cosmetic composition that reduces waviness of hair and further reduces recurrence of waviness due to combing, and that is excellent in the effects of finger passage, cohesion and gloss on the hair.

Hereinafter, the hair cosmetic composition of the present invention will be described in detail.

The beeswax (A) blended in the hair cosmetic composition of the present invention is a wax obtained from a residue obtained by removing honey from a beehive by a heating press method or a solvent extraction method. In the present invention, the blending amount is not particularly limited, but is preferably in the range of 0.01 to 5.0 mass% (hereinafter, mass% is simply represented by “%” unless otherwise specified). .. Within this blending amount range, waviness is reduced without feeling stickiness or hardness on the hair, recurrence of waviness due to combing is further reduced, and recurrence of waviness due to combing is further reduced. Although the effect of the present invention that the fingers pass through, become cohesive and glossy can be sufficiently exerted, when the blending amount is less than 0.01% by mass, a sufficient waviness suppressing effect cannot be obtained and the combing is performed. When the amount of the compounding agent exceeds 5% by mass, the hair after application of the hair cosmetic composition becomes excessively sticky and the fingers cannot pass smoothly.

The blending amount of the component (B) is not particularly limited, but is preferably 0.001 to 10.0%. When the amount is in this range, the effect of the present invention of suppressing undulation can be sufficiently exhibited without feeling stickiness or weight on the hair. If the blending amount is less than 0.001%, a sufficient waviness suppressing effect may not be obtained, and the hair may not be cohesive. If the blending amount exceeds 10.0%, a sticky feeling may remain on the hair, which may result in poor finger passage.

The component (C) used in the detergent composition of the present invention is one or more selected from ester oils which are liquid at 20°C. Component (C) is not particularly limited as long as it is an ester oil that is liquid at 20° C., but isodecyl neopentanoate, ethylhexyl palmitate, cetyl ethylhexanoate and the like are preferable. In the hair cosmetic composition of the present invention, the above compounds may be used alone or in combination of two or more.

The compounding amount of the component (C) is not particularly limited, but is preferably 0.001 to 10.0%. Within the range of this blending amount, the effect of the present invention that the swelling is suppressed can be sufficiently exhibited without feeling stickiness or weight on the hair. If the blending amount is less than 0.001%, a sufficient waviness suppressing effect may not be obtained, and the hair may not be cohesive. If the blending amount exceeds 10.0%, a sticky feeling may remain on the hair, which may result in poor finger passage.

Further, the hair cosmetic composition of the present invention can be appropriately blended with known components within a range that does not impair the effects of the present invention. Known components include, for example, nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene sorbitan fatty acid ester, and glycerin fatty acid ester; stearoxypropyltrimonium chloride, distearyldimonium chloride, behenzimonium ethyl phosphorus. Cationic surfactants such as stearyl acid; ester oils such as isopropyl myristate; hydrocarbons such as liquid isoparaffin, vaseline, squalane; dimethylpolysiloxane (dimethicone), dimethicone, amodimethicone, amino-modified silicone, polyether-modified silicone, etc. Silicones; pH adjusting agents such as lactic acid and citric acid; antidandruff components such as zinc pyrithione and benzalkonium chloride; lower alcohols such as ethanol, methanol, propyl alcohol, isopropyl alcohol; L-aspartic acid, sodium L-aspartate , DL-alanine, L-arginine, glycine, L-glutamic acid, L-cysteine, L-threonine, and other amino acids; phenoxyethanol, methylparaben, ethylparaben, propylparaben, methylchloroisothiazolinone, and other preservatives; other ultraviolet absorbers, Examples include fragrances, coloring agents, sequestering agents for metal ions, antioxidants, and various agents.
