Benefits of technology

The two-layer composition effectively provides a stickiness-free finish, enhances hair smoothness and tidiness, and ensures easy application, maintaining a homogeneous state initially before separating into layers, thus addressing the limitations of previous formulations.

Problems solved by technology

In recent years, it has been said that owing to the influence of chemical treatment such as hair coloring or physical treatment by blow drying, cuticles on the hair surface peel off or the hair becomes porous by the efflux of lipids from the inside of the hair and as a result, the hair inevitably becomes excessively dry, resistant to finger combing (i.e., easily entangled), untidy and lusterless.
However, because the highly polymerized silicones are difficult to be emulsified, it is usually present in an oil type composition such as hair oil that does not contain water.
Such composition tends to have a sticky and unfresh feeling and has bad spreadability on the hair.
As a result, it cannot easily spread over the whole hair and is not desirable in terms of tidiness of the hair.
Meanwhile, in the case of an emulsion type system in which a surfactant is used with water, it is difficult to include the highly polymerized silicones in a sufficient amount, resulting in a problem in tidiness of the hair.
However, such a hair cosmetic composition cannot provide a good finish due to the sticky nature of the oil formulation.

Abstract

A leave-on type hair cosmetic composition having the following two layers A and B:Layer A of an oil layer containing the following component (a) in an amount of 0.5-40% by mass in the hair cosmetic composition,(a) a highly polymerized silicone selected from dimethicone and dimethiconol and having a number average degree of polymerization of 1,000-20,000; andLayer B of a water layer containing the following components (b) and (c),(b) a water-soluble polymeric thickening agent, and(c) water.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a leave-on type hair cosmetic composition having two or more layers.BACKGROUND OF THE INVENTION[0002]In recent years, it has been said that owing to the influence of chemical treatment such as hair coloring or physical treatment by blow drying, cuticles on the hair surface peel off or the hair becomes porous by the efflux of lipids from the inside of the hair and as a result, the hair inevitably becomes excessively dry, resistant to finger combing (i.e., easily entangled), untidy and lusterless.[0003]Existing leave-on type hair cosmetic compositions which have been used for providing the hair with smoothness, luster, tidiness, and protecting the hair from excessive drying are, emulsion type products such as hair cream wax containing silicones, wax, higher alcohols, and surfactant, etc. In addition, in order to further improve the effect of providing the hair with smoothness, luster, and tidiness, it has been also known tha...
