Description

  The present invention relates to hair cosmetics such as hair gel, hair milk, hair wax, hair rinse and the like, and more particularly, it is easy to apply to hair that has been subjected to decoloring treatment, imparts gloss and moisture to the hair, keeps the moisture after washing, and The present invention relates to a hair cosmetic that can impart good finger-penetrating properties to hair and prevent hair from being caught and tangled.

  2. Description of the Related Art Conventionally, hair cosmetics are required to have performances such as good finger fingering and glossiness. Therefore, oily components such as hydrocarbon oils, ester oils, and silicones are blended in hair cosmetics. Among these, since silicone has a small surface tension and excellent lubricity, it is widely used in hair cosmetics because when applied to hair, it spreads thinly and uniformly and imparts good slipperiness to hair.

  For example, Patent Document 1 discloses a hair cosmetic that combines an amidoamine compound, a higher alcohol, a poorly water-soluble solid powder, and silicone. Furthermore, Patent Document 2 discloses a hair cosmetic that combines an ether type cationic surfactant and an amino-modified silicone.

  However, in recent years, hair dyeing has become widespread, and decoloring treatment such as hair coloring and bleaching is increasing on hair. In the decolorized hair, intercellular lipids and proteins are oxidized and denatured, and when the hair is washed, such as shampoo, it gradually flows out, and the cuticle is partially peeled off, so that part of the hair surface is highly hydrophilic. Become. As a result, there is a problem that the hair subjected to the decoloring treatment is not easily adapted to silicone, and sufficient finger-penetrating properties are not imparted. Furthermore, since the cationic surfactant is highly irritating to the skin, it may cause rough skin when attached to the scalp.

  Furthermore, not only chemical action such as decoloring treatment, but also physical action such as shampooing and brushing routinely causes the hair to have a reduced breaking strength. As a result, when hair is caught or tangled during hair washing and brushing, stress is applied, resulting in breakage. When the number of cut hairs increases, there is a problem that not only does the finger passability deteriorate, but the texture of the appearance is also impaired.

For example, Patent Document 3 discloses a hair cosmetic that prevents cut hair by combining a polyether-modified silicone and an alkyl-modified silicone. However, although this hair cosmetic has an effect of preventing cut hair, it cannot always keep moisture after washing.
JP 2003-201218 A JP 2003-327510 A Japanese Patent Laid-Open No. 7-285834

  It is an object of the present invention to be easily applied to hair that has been subjected to decolorization treatment, to give gloss and moisture to the hair, to keep it moist after washing, and to give the hair good fingering properties, and to prevent the hair from being caught and tangled The object is to provide a hair cosmetic capable of preventing hair.

  As a result of repeated research to solve the above problems, it has been found that a desired hair cosmetic can be obtained by combining a specific glycerin derivative and a silicone or a silicone derivative in a specific ratio, thereby completing the present invention. It came.

That is, the hair cosmetic composition of the present invention is a hair cosmetic composition containing a glycerin derivative (a) and a silicone compound (b), wherein the glycerin derivative (a) is a derivative represented by the formula (I):
Gly- [O (PO) _m (EO) _n- (BO) _pH ] ₃ (I)
(Wherein Gly is a residue obtained by removing a hydroxyl group from glycerin, PO is an oxypropylene group, EO is an oxyethylene group, and m and n are average added moles of PO and EO, respectively, The mass ratio of PO to EO (PO / EO) is 1/5 to 5/1, BO is an oxyalkylene group having 4 carbon atoms, and p is the average added mole number of BO. And p is the value of 1 to 5), and p is the value of 1 to 5 indicating the average added mole number of BO. And the silicone compound is at least one compound selected from the group consisting of silicone and silicone derivatives, wherein the glycerin derivative (a) is 0.1 to 40% by mass in the hair cosmetic composition, And this silicone compound (b) is contained in the ratio of 0.1-10 mass%.

  The oxyalkylene group having 4 carbon atoms represented by BO means an oxybutylene group, an oxyisobutylene group and / or an oxytetramethylene group.

  The hair cosmetic composition of the present invention is easily applied to hair that has been subjected to decolorization treatment, imparts gloss and moisture to the hair, keeps it moist after washing, and imparts good finger-penetrating properties to the hair. Can prevent the hair from cutting.

  The hair cosmetic composition of the present invention comprises the following glycerin derivative (a) (hereinafter sometimes referred to as compound a, component a) and silicone compound (b) (hereinafter sometimes referred to as compound b, component b). Including an additive and a solvent such as water as necessary. Hereinafter, these will be sequentially described.

(Glycerin derivative (a))
The glycerin derivative (a) used in the hair cosmetic composition of the present invention is obtained by adding propylene oxide and ethylene oxide to glycerin at a ratio of 3 to 150 molar equivalents to glycerin, and then converting alkylene oxide of 4 carbon atoms to glycerin. It is obtained by adding at a ratio of 3 to 15 molar equivalents. That is, the glycerin derivative (a) is obtained by once synthesizing an adduct of PO and EO and then adding a C4 alkylene oxide in a block form.

  The mass ratio (PO / EO) of propylene oxide (PO) and ethylene oxide (EO) is 1/5 to 5/1, and the addition form of propylene oxide and ethylene oxide may be random or block. In order to maintain a higher moisture after washing the hair, it is preferable to add it randomly. When the mass ratio of propylene oxide and ethylene oxide (PO / EO) is less than 1/5, the effect of imparting fingering properties and gloss to hair is weakened. When it exceeds 5/1, the effect of moisturizing the hair is weakened.

  The average added moles of propylene oxide (PO) and propylene oxide (EO) are each preferably in the range of 1-50. If the average added mole number of PO and EO is less than 1, it is difficult to be applied to the decolorized hair, the effect of preventing hair breakage is weak, and the moisture after washing is not maintained. When the average number of added moles exceeds 50, the hair cannot be moisturized and the effect of preventing hair breakage is further weakened.

  The average number of added moles of alkylene oxide (BO) having 4 carbon atoms is preferably in the range of 1-5. If the average added mole number of BO is less than 1, it will become difficult to adjust to decolorized hair. When the average number of added moles exceeds 5, it becomes difficult to adjust to decolorized hair.

  Examples of the alkylene oxide having 4 carbon atoms include 1,2-butylene oxide, 2,3-butylene oxide, and tetramethylene oxide (tetrahydrofuran). Among these, 1,2-butylene oxide is preferable from the viewpoint of easy availability and reaction control.

  Usually, when these alkylene oxides are added to glycerin, the addition reaction is performed using an alkali catalyst, a phase transfer catalyst, a Lewis acid catalyst, or the like. In general, it is preferable to use an alkali catalyst such as potassium hydroxide.

(Silicone compound (b))
The silicone compound (b) used in the hair cosmetic composition of the present invention is a silicone and a silicone derivative. In the present invention, silicone refers to dimethylpolysiloxane. Examples of the silicone derivative include methylphenyl polysiloxane, alkyl-modified silicone, amino-modified silicone, and polyether-modified silicone. The average degree of polymerization of these silicone compounds is not particularly limited. However, from the viewpoint of the effect of imparting finger touch and gloss to the hair, a silicone or a silicone derivative having an average degree of polymerization of 500 to 10,000 is preferable, and a silicone having an average degree of polymerization of 500 to 10,000 is more preferable.

(Additive)
Additives that can be included in the hair cosmetic composition of the present invention can be contained in the hair cosmetic composition within a range that does not impair the effects of the present invention. Examples of additives include hydrocarbon oils such as liquid paraffin and liquid isoparaffin; natural fats and oils such as beef tallow, lard and fish oil; synthetic triglycerides such as glyceryl tri-2-ethylhexanoate; oleyl oleate and octyldodecyl myristate Ester oils such as beeswax, carnauba waxes, etc .; nonionic surfactants such as polyoxyethylene alkyl ether and fatty acid esters of polyethylene glycol; cationic surfactants such as alkyltrimethylammonium chloride; alginic acid, carboxyvinyl polymer Water-soluble polymer compounds such as: pyrrolidone carboxylates, citrates, malates, salt and other organic or inorganic salts; pH and acid adjusting agents and alkalis; bactericides; chelating agents; antioxidants; Agents; vitamins Natural extracts derived from plants and animals; dyes; pigments; and perfumes and the like.

(Hair cosmetic)
As described above, the hair cosmetic composition of the present invention contains a glycerin derivative (component a) and a silicone compound (component b) in a specific ratio, and optionally contains an additive, a solvent (for example, water) and the like.

  The component a is contained in the hair cosmetic in an amount of 0.1 to 40% by mass, preferably 0.5 to 25% by mass. When the amount is less than 0.1% by mass, it is difficult to adjust to the decolorized hair, the hair is not moisturized, the effect of preventing hair breakage is weakened, and the moisture after washing is not maintained. When it exceeds 40 mass%, a sticky feeling will be felt and finger passage will worsen. A component may be used independently and may use 2 or more types together.

  Component b is contained in the hair cosmetic in an amount of 0.1 to 10% by mass, preferably 0.2 to 5% by mass. When the amount is less than 0.1% by mass, the finger penetration of the hair is deteriorated and it is difficult to give gloss. When it exceeds 10 mass%, a sticky feeling will be felt and finger fingering property will worsen. b component may be used independently and may use 2 or more types together.
