Description

Non-aqueous conditioner composition

The present invention relates to a non-aqueous conditioner composition.

Hair damaged by frequent dyeing, perm, etc. is not glossy, crumbly, and hair is difficult to trim. Even in the case of healthy hair, using only shampoo removes oil from the hair due to excessive washing, resulting in lack of gloss and difficulty in maintaining calm hair due to static electricity. In order to overcome this, emulsion-type conditioners composed of hair conditioning materials such as higher alcohols, cationic surfactants, water, and silicones are generally used. However, conditioners of such emulsion formulations have the disadvantage of slowing down the penetration of conditioning components into hair in the case of severely damaged hair.

For example, Korean Patent Laid-Open Publication No. 2003-0050371 discloses a conventional aqueous conditioner composition containing water, lower alcohols, polyols, higher fatty alcohols and cationic surfactants to solve the above problems. However, due to the low viscosity, when used on the hair, it is crumbly and lustrous after drying, and there is a disadvantage that the use of silicones that exhibits an excellent effect in providing softness and shine to the hair is extremely limited.

This is because silicone becomes unstable by water, and silicone gives gloss and smoothness to hair, but stability is deteriorated by water. In addition, the water lowers the solubility of the higher alcohol, so as the water content increases, the lower alcohol content, such as ethanol, must be increased. Lower alcohols such as ethanol have the disadvantage of removing the lipid component of the hair. Therefore, the conventional conditioner composition contains silicon but does not contain water because it does not secure the stability of the silicone, the problem that the gloss after the hair dries occurs.

Therefore, the technical problem to be achieved by the present invention is to protect the stability of the silicone contained in the non-aqueous conditioner composition of the present invention to increase the viscosity of the non-aqueous conditioner that can give a soft texture and excellent gloss to wet hair as well as dry hair To provide a composition.

In order to achieve the above technical problem, the non-aqueous conditioner composition of the present invention comprises 1 to 90% by weight of a polyol having two or more hydroxy groups; 1 to 50% by weight of lower alcohol having one hydroxy group and having 6 or less carbon atoms; 0.1 to 10% by weight of a higher alcohol having 12 to 22 carbon atoms represented by Formula 1; 0.1 to 10% by weight cationic surfactant; And 0.01 to 10% by weight of silicone.
