Description

  The present invention has no substance having an unpleasant sensation in the preparation at the time of use, is stable, is excellent in touch and finger feeling during rinsing when applied to the hair, and moisturized hair after towel drying, It is a hair cosmetic that can provide an excellent feeling of smoothness, smoothness, softness, and residual scent.

  Hair cosmetics such as rinses, conditioners and treatments are used for the purpose of improving the feel of hair after shampooing, repairing the damage of hair damaged by bleach or perm and improving the feel. In these hair cosmetics, emphasis is placed on the feeling of application to hair and the feeling after drying, and various polymer formulations have been proposed to improve the feel.

  For example, Japanese Patent Publication No. 62-29403 (Patent Document 1) discloses one or more polymers selected from hyaluronic acid, chondroitin sulfate, alginic acid, and alginic acid alkylene glycol ester, a specific cationic surfactant, and a higher alcohol. There has been proposed a composition for hair combining the above. However, sugars with high anionization density such as hyaluronic acid, chondroitin sulfate, and alginic acid, when mixed with a cationic surfactant, form a water-insoluble complex, which is not uniformly dispersed in the preparation system and cannot be stably blended. In addition, this water-insoluble matter not only adversely affects the touch at the time of application, but also gives hair stiffness during drying, causing problems in terms of smoothness and gloss. On the other hand, alginic acid alkylene glycol ester did not produce an insoluble matter, but remained little on the hair due to rinsing, and the effect of improving touch was insufficient.

Japanese Patent Publication No.62-29403

  In view of the above-mentioned problems of the prior art, the object of the present invention is that the application to the hair is smooth, the touch and finger feeling when rinsing the hair are excellent, the moist feeling of the hair after towel drying, and the smooth feeling An object of the present invention is to provide a hair cosmetic that is excellent in smoothness, softness, and residual scent.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors combine a cationic surfactant, an organic acid and / or an electrolyte with a propylene glycol alginate partial ester having a specific degree of esterification in combination. The feel when applied is smooth, and the feel and fingering when rinsing the hair are excellent, and the hair after towel drying is moist, smooth, smooth, soft, and residual fragrance. The present inventors have found that a hair cosmetic that can impart a good feel can be obtained, and have completed the present invention.

  That is, the present invention comprises (a) a cationic surfactant, (b) a propylene glycol alginate partial ester having an esterification degree of 60% or more and less than 95%, (c) an organic acid and / or electrolyte, and (d) water. A hair cosmetic composition is provided.

  Hereinafter, the present invention will be described in detail.

  The cationic surfactant of component (a) used in the present invention is not particularly limited as long as it can be used in cosmetics. From the viewpoint of the effect of smoothness on hair, for example, stearyl chloride Alkyltrimethylammonium salts such as trimethylammonium chloride, cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, lauryltrimethylammonium chloride, distearyldimethylammonium chloride dialkyldimethylammonium salt, poly (N, N′-dimethyl-3,5-methylenepi) chloride Peridinium), alkyl pyridinium salts such as cetyl pyridinium chloride, alkyl quaternary ammonium salts, alkyl dimethyl benzyl ammonium salts, alkyl isoquinolinium salts, dialkyl morpholinium salts, POE alkyl amines, Examples include alkylamine salts, polyamine fatty acid derivatives, amyl alcohol fatty acid derivatives, benzalkonium chloride, benzethonium chloride, β-N-N-dimethyl-N-ethylammonioethyl salt vinyl pyrrolidone copolymers, and mixtures thereof. However, it is not limited to these examples. Of these, alkyltrimethylammonium salts and dialkyldimethylammonium salts are preferably used.

  (A) As for the compounding quantity of a component, 0.1-5.0 mass% is preferable in hair cosmetics whole quantity, Most preferably, it is 0.5-3.0 mass%. If it is less than 0.1% by mass, it is difficult to obtain a sufficient conditioning effect. On the other hand, if it exceeds 5.0% by mass, the viscosity of the hair cosmetic tends to be too high.

  As the component (b), propylene glycol alginate partial ester having a degree of esterification of 60% or more and less than 95%, preferably 75% or more and less than 95% is used. The “degree of esterification” referred to here indicates the proportion of carboxylic acid constituting alginic acid that is esterified. If the degree of esterification is less than 60%, an insoluble material is produced in the preparation system, not only is it not stable, but also the feel when applied to hair and when dried is not smooth. On the other hand, when the degree of esterification is 95% or more, a moist feeling, a smooth feeling, a residual scent feeling and the like after towel drying cannot be obtained sufficiently.

  The blending amount of the component (b) is preferably 0.01 to 5.0% by mass, particularly preferably 0.05 to 3.0% by mass in the total amount of the hair cosmetic. If the amount is less than 0.01% by mass, a sufficient feeling improving effect cannot be obtained. On the other hand, if it is 5.0% by mass or more, the feeling of sensory evaluation is further deteriorated, resulting in stickiness.

  The component (c) is an organic acid and / or an electrolyte. Although it will not specifically limit as an organic acid if it can be generally used for cosmetics, Citric acid, lactic acid, tartaric acid, malic acid, etc. are used preferably. As the electrolyte, organic acid salts, inorganic acid salts, and acidic amino acid salts are preferably used.

Examples of the salt include alkali metal salts (for example, sodium salts, potassium salts, lithium salts), alkaline earth metal salts (for example, calcium salts, magnesium salts, strontium salts, etc.), ammonium salts, and the like. It is not limited. Among them, citric acid, lactic acid, tartaric acid or sodium salts, potassium salts, magnesium salts, ammonium salts thereof, or sodium salts, potassium salts, magnesium salts, ammonium salts of acidic amino acids such as hydrochloric acid, glutamic acid, aspartic acid, etc. are used. From the viewpoint of stability and stability, it is preferably used. (C) A component can use 1 type (s) or 2 or more types.

  (C) As for the compounding quantity of a component, 0.001-5.0 mass% is preferable in hair cosmetics whole quantity, Most preferably, it is 0.01-2.0 mass%. If the amount is less than 0.001% by mass, the feeling improvement effect cannot be sufficiently obtained. On the other hand, if the amount is 5.0% by mass or more, not only the usability of the preparation is not excellent, but also the residue on the hair is lowered. It is difficult to obtain.

  (D) Water is mix | blended as a component.
