DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP95/0084.
TECHNICAL FIELD
The present invention relates to a hair cosmetic composition which imparts satisfactory firmness/elasticity to hair fibers in a short time, which holds the firmness/elasticity for a long time, and which at the same time provides the hair with conditioning effects.
BACKGROUND ART
Not a few complaints about the hair are caused from the low elasticity of hair fibers such as lack of firmness/elasticity and less volume. In order to meet the needs of people having such complaints, a variety of hair treatment compositions have heretofore been proposed which contain components for providing firmness/elasticity and components with conditioning effects. A majority of them exhibit their effects when they are adsorbed onto the surfaces of hair fibers, but the adsorbed compositions are rinsed off upon shampooing. Therefore, repeated treatments are needed, which is not convenient. Separately, attempts have been made to obtain an effect by permeating a hair treatment composition into hair fibers. However, the permeability of the composition is poor and requires a prolonged time for treatment while producing only an insufficient effect.
Hair treatment compositions proposed by EP-A-0529437 comprise an organic solvent and an aromatic sulfonic acid. Although this composition imparts firmness/elasticity to hair fibers in a short time and the effects of the composition are long-lasting, the conditioning effects of the composition such as providing moistness, smoothness, etc. to hair fibers are still unsatisfactory.
Accordingly, hair cosmetic compositions capable of imparting firmness/elasticity to hair fibers in a short time, holding the firmness/elasticity for a long time, and providing the hair with satisfactory conditioning effects are still desired.
DISCLOSURE OF THE INVENTION
Accordingly, the present invention provides a hair cosmetic composition which comprises the following components (A), (B), (C), and (D):
According to the present invention, satisfactory firmness/elasticity can be given to hair fibers through a short-term treatment due to the incorporation of an organic solvent, a naphthalene sulfonic acid and/or a benzophenone sulfonic acid, an anionic surfactant and/or an amphoteric surfactant, and an oily agent, and the effects obtained are long-lasting. In addition, conditioning effects can also be given to the hair.
BEST MODE FOR CARRYING OUT THE INVENTION
The organic solvent which is used in the present invention as component (A) is compatible with water. Examples of the organic solvent (A) include the compounds of the following formula (1), N-alkylpyrrolidones of the following formula (2), and C1-C4 alkylene carbonates. ##STR1## wherein R.sup.1 represents hydrogen, lower alkyl, or a group ##STR2## (wherein R.sup.2 represents hydrogen, methyl, or methoxy, R.sup.3 represents a direct bond or a C1-C3 saturated or unsaturated divalent hydrocarbon group), Y and Z each represents hydrogen or hydroxy, p, q, and r are integers of from 0 to 5, with the exception of the cases where p.dbd.q.dbd.r.dbd.0 and Z.dbd.H; and p.dbd.q.dbd.r.dbd.0, R.sup.1 =H, and Z.dbd.OH. ##STR3## wherein R.sup.4 represents C1-C18 linear or branched alkyl.
Among the above-described species of component (A), the aromatic alcohols of the following formula (3) are especially preferred. ##STR4## wherein R.sup.5 is hydrogen or methyl, s is an integer from 0 to 5 inclusive, and R.sup.2 and R.sup.3 have the same meaning as described above with the exception that R.sup.3 is not a direct bond if s is equal to 0.
Specific examples of the organic solvent (A) include ethanol, isopropanol, n-propanol, n-butanol, isobutanol, ethylene glycol, propylene glycol, 1,3-butanediol, benzyl alcohol, cinnamyl alcohol, phenethyl alcohol, p-anisyl alcohol, p-methylbenzyl alcohol, phenoxy ethanol, phenoxy isopropanol, 2-benzyloxyethanol, methyl carbitol, ethyl carbitol, propyl carbitol, butyl carbitol, triethylene glycol monoethylether, triethylene glycol monobutyl ether, glycerol, N-methylpyrrolidone
