Claims
- 1. A method of preventing generation of split hair or torn hair for restoring worn hair which comprises applying to the hair a hair cosmetic composition comprising
- (a) 0.1% to 50% by weight of at least one high molecular weight silicone having the formula (I): ##STR5## wherein R.sup.1 represents a methyl group or a part thereof represents a phenyl group,
- R.sup.2 represents a methyl or hydroxy group, and
- n represent an integer from 3000 to 20000; and
- (b) 1 to 50-fold by weight, relative to the high molecular weight silicone, of a low boiling-point oil having a boiling point of 60.degree. C. to 260.degree. C. at normal pressure.
- 2. A method as claimed in claim 1, wherein the hair cosmetic composition is an oil-in water emulsified cosmetic composition containing a nonionic, cationic, or anionic surfactant.
- 3. A method as claimed in claim 2, wherein the emulsified cosmetic composition is an emulsified cosmetic composition which is emulsified by mixing a mixture of a water-soluble polyhydric alcohol and a surfactant with an oil phase.
- 4. A method as claimed in claim 1, wherein said hair cosmetic composition comprises:
- (A) 0.1% to 25% by weight of at least one high molecular weight silicone having the formula (I): ##STR6## wherein R.sub.1 represents a methyl group or a part thereof represents a phenyl group,
- R.sub.2 represents a methyl or hydroxy group, and
- n represents integer from 3000 to 20000;
- (B) 1% to 98.9% by weight of at least one cyclic silicone; and
- (C) 1% to 98.9% by weight of a component selected from the group consisting of trichlorotrifluoroethane, tetra-chlorodifluoroethane and mixtures thereof.
- 5. A method as claimed in claim 1, wherein said hair cosmetic composition comprises:
- (A) 0.1% to 25% by weight of at least one high molecular weight silicone having the formula (I): ##STR7## wherein R.sub.1 represents a methyl group or a part thereof represents a phenyl group,
- R.sub.2 represents a methyl or hydroxy group, and
- n represents an integer from 3000 to 20000;
- (B) 45% to 98.9% by weight of at least one cyclic silicone; and
- (C) 1% to 30% by weight of at least one lower alcohol selected from the group consisting of ethanol, isopropyl alcohol and mixtures thereof.
- 6. A method as claimed in claim 1, wherein said hair cosmetic composition is an aerosol hair cosmetic composition comprising:
- (A) 0.1% to 25% by weight of at least one high molecular weight silicone having the formula (I): ##STR8## wherein R.sub.1 represents a methyl group or a part thereof represents a phenyl group,
- R.sub.2 represents a methyl or hydroxy group, and
- n represents an integer from 3000 to 20000;
- (B) 1% to 98.9% by weight of a component selected from the group consisting of trichlorotrifluoroethane, tetrachlorodifluoroethane and mixtures thereof; and
- (C) 5% to 95% by weight of an aerosol propellant.
- 7. A method as claimed in claim 6, wherein the aerosol propellant is at least one compound selected from the group consisting of trichlorofluoromethane, dichlorodifluoromethane, dichlorotetrafluoroethane, monochlorodifluoromethane, dimethylether, pronane, isobutane and n-butane.
- 8. A method as claimed in claim 1, wherein the low boiling-point oil is at least one member selected from the group consisting of dimethylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane and an isoparaffinic hydrocarbon having 1 to 30 carbon atoms.
- 9. A method as claimed in claim 1, wherein said low boiling point oil is one of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane.
- 10. A method as claimed in claim 1, wherein the low boiling-point oil is at least one member selected from the group consisting of hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane and hexadecamethylheptasiloxane.
