Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hair which suppresses the dryness of the tips of damaged hair such as split ends, gives a dry feeling and smoothness, and gives a good feeling to the hair without stickiness. Regarding cosmetics.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
Various oil agents have been incorporated into hair cosmetics for the purpose of imparting flexibility and wettability to the hair, protecting the hair and improving the feel. Among these oil agents, silicones typified by dimethylpolysiloxane polymers are smooth and have excellent lubricity as compared with higher alcohols, glycerides, liquid paraffins, esters, etc., and have a smooth feel and gloss on hair. It is used in many hair cosmetics because it is known to give. However, even a dimethylpolysiloxane polymer having a high degree of polymerization has a problem that it has stickiness peculiar to silicone.

As the cosmetics which give the hair a glossy and smooth feel, for example, hair cosmetics using a high molecular weight silicone polymer (Japanese Patent Laid-Open No. 63-313714) and hairs using an organic silicone resin. Cosmetics (JP-A-3-193718, JP-A-5-65216) Hair cosmetics (JP-A-63-313713) using high molecular weight silicone and organic silicone resin are known.

However, although these hair cosmetics have some effect on hair with little damage, they are not effective on split ends or broken hair, and obtain a sufficient effect. Therefore, when used in a large amount, the oily feeling of the hair becomes strong and there is a drawback that it becomes sticky. Therefore, there has been a demand for a hair cosmetic composition that imparts smoothness to damaged hair and provides a good feel without stickiness.

[0005]

Under such circumstances, the inventors of the present invention have conducted diligent research and, as a result, have combined a specific amount of a specific organic silicone resin, a silicone compound containing a nitrogen atom, a cationic surfactant and a solvent. It was found that an excellent hair cosmetic that solves the above-mentioned problems can be obtained by using the same, and completed the present invention.

That is, the present invention provides the following components (A) to
(D): (A) consists of (R) ₃ SiO _1/2 units and SiO ₂ units, and the ratio of (R) ₃ SiO _1/2 units to SiO ₂ units is _{1/2 to 3/2.} Organosilicone resin (provided that R represents a linear or branched hydrocarbon group having 1 to 6 carbon atoms or an aryl group) 0.01 to 50% by weight (B) Cationized silicone 0.01 to 20% by weight ( C) Cationic surfactant 0.01 to 20% by weight (D) A cosmetic capable of dissolving the organic silicone resin of component (A) 0.05 to 99% by weight is provided. is there.

The organosilicone resin as the component (A) used in the present invention imparts the property of adhering the split ends, and is a resin composed of (R) ₃ SiO _1/2 units and SiO ₂ units. . Here, R in the (R) ₃ SiO _1/2 unit has 1 to 6 carbon atoms.
Shows a linear or branched hydrocarbon group or an aryl group, and examples of the hydrocarbon group include a methyl group, an ethyl group, an isopropyl group, a vinyl group and the like, and an aryl group such as a phenyl group, Examples thereof include naphthyl group. Other substituents such as a halogen atom may be present in these groups.

The ratio of (R) ₃ SiO _1/2 unit to SiO ₂ unit is _{1/2 to 3/2} .

The average molecular weight of these organic silicone resins varies depending on the characteristics of the intended hair cosmetic,
In order to obtain a sufficient adhesive effect on damaged hair, it is generally 1,500 to 10,000, particularly 2,000 to 8,000.
It is preferably 0.

The organic silicone resin as the component (A) can be manufactured by a conventional method. For example, (R) ₃ SiX, (R) ₂ SiX ₂ , RSiX ₃ and SiX (X is a halogen atom such as chlorine, an alkoxy group such as a methoxy group, and a hydrolyzable group such as an acyloxy group such as an acetyloxy group. The compound represented by (1) is dissolved in a solvent such as toluene so as to obtain a desired resin composition, polymerized and hydrolyzed. The organic silicone resin produced by this method is soluble in a solvent such as toluene or xylene.

The organosilicone resin as the component (A) can be used alone or in combination of two or more kinds, and is 0.01 to 50% by weight (hereinafter simply indicated by%), preferably 0 in the total composition. 1 to 30% is blended. If it is less than 0.01%, the adhesive effect on damaged hair will be insufficient, and if it exceeds 50%, the degree of curing of the organic silicone resin film will be strong and the adhesive force to hair will be reduced.

Examples of the cationized silicone as the component (B) include the following (B-1) to (B-2).

Fatty acids such as capric acid, lauric acid, myristic acid, pantadecanoic acid, palmitic acid, margaric acid, stearic acid, arachidic acid, behenic acid, ligseric acid, 12-hydroxystearic acid, lanolin fatty acid; dodecyl laurate, octadecyl laurate , Tetradecyl myristate, decyl palmitate, tetradecyl palmitate, octadecyl palmitate, propyl stearate, hexadecyl stearate, docosyl behenate,
Propylene glycol stearate, lanolin acetate, monoglyceride, diglyceride, triglyceride, esters such as esters of trimethylolmethane or pentaerythritol with fatty acids, beeswax, carnauba wax, whale wax, candelilla wax, kapok wax, hydrogenated lanolin, waxes such as hard lanolin. Examples thereof include animal and vegetable oils such as cocoa butter, palm oil, coconut oil, beef tallow, lard, and hydrogenated oil.

These oils and fats can be used alone or in combination of two or more, and the total composition is 0.01-5.
It is preferable to add 0%, particularly 1 to 20%.

Furthermore, the hair cosmetic composition of the present invention contains the components used in ordinary hair cosmetic compositions, such as nonionic surfactants, amphoteric surfactants, squalene, liquid lanolin, methylphenylpolysiloxane, and polyethers. Modified silicone, carboxy-modified silicone, perfluoropolyether, JP-A-58-53996 and JP-A-1-11
Feel improvers such as cationic polymers as described in Japanese Patent No. 7821, humectants such as propylene glycol, glycerin and sorbitol, methyl cellulose, carboxyvinyl polymer, hydroxyethyl cellulose,
Viscosity modifiers such as polyoxyethylene glycol distearate, ethanol, pearling agents, fragrances, dyes, UV absorbers, antioxidants, antibacterial agents such as triclosan and trichlorocarbane, antibacterial agents such as potassium glycyrrhizinate and tocophenol acetate. Inflammatory agents, anti-dandruff agents such as zinc pyrithione and octopirox, preservatives such as methylparaben and butylparaben, and other Encyclopedia of
Shampoo Ingredients (Mice
llepress, 1985) and the like, and the like, can be optionally added within a range that does not impair the effects of the present invention.

The hair cosmetic composition of the present invention can be produced according to a conventional method, and preferably has a pH of 3 to 10, more preferably 3.5 to, by a known acidic or alkaline drug.
Adjust to 8.

The hair cosmetic composition of the present invention can be in the form of an aqueous solution, an ethanol solution, an emulsion, a suspension, a gel, a solid, an aerosol or the like as a dosage form, and it can be used in various cosmetics applied to hair. Embodiments, for example, pre-shampoo, shampoo, hair rinse, hair conditioner, hair treatment, set lotion, styling lotion, hair spray, foam styling agent, gel styling agent, hair liquid, hair tonic, hair cream, temporary hair dye Can be used as such.

EFFECTS OF THE INVENTION The hair cosmetic composition of the present invention has sufficient adhesiveness to damaged hair such as split ends and broken hair, so that it suppresses the dryness of the tips of the hair and gives a smooth feel and smoothness. Moreover, there is no stickiness and a good feeling can be imparted.

Example 1 Hair treatments having the compositions shown in Table 6 were produced by a conventional method, and the smoothness, dry feeling, dryness, tackiness and cohesion when used were evaluated. The results are shown in Table 1.

(Evaluation method) 20 g (20 cm in length) of hair of a Japanese woman with split ends was bundled, and for rinse-type hair cosmetics, 2 g of the agent was uniformly applied to this hair bundle, and then running water was run for 30 seconds. After rinsing, towel drying, and drying with a dryer. Further, with respect to the hair rinsing-free type cosmetic, a predetermined amount of the agent was applied to this hair bundle and then air-dried. This hair bundle was sensory-evaluated according to the following criteria.
