Description

Hair cosmetic composition

The present invention relates to a hair cosmetic composition, specifically a dialkyl carbonate and a lipid component, which inherently repairs damaged parts of the hair, imparts shine, orderiness and softness to the hair, and does not need to be washed away. It relates to a hair cosmetic composition which can be produced.

Modern hair has a phenomenon of frequent chemical treatments such as perming and dyeing, and the effect of hair washing, which causes peeling of the epidermis on the surface of the hair or leakage of lipids inside the hair, causing the inside of the hair to cavify. Despite many studies to restore hair damaged by frequent chemical treatments and haircuts to its original healthy state, the results have been small.

As a non-washable hair cosmetic that is currently used mainly, an emulsified product or a film-forming polymer of a hair cream type containing wax, a higher alcohol, a surfactant, or the like is added to provide hair with cleanliness and prevent looseness. Gel-containing products. Such hair cosmetics can temporarily solve the untidy and loose problem by forming a film-like structure by attaching oils or polymers to the surface of the hair, but it does not inherently heal damaged hair.

EP 1579843 discloses a composition containing an organic carboxylic acid or a salt thereof for essentially repairing the hair. Korean Patent Publication No. 98-8206 discloses a technique for preparing capsules containing cholesterol, long chain fatty acids, long chain fatty alcohols, ceramides, and the like, and prescribing them appropriately in a product. US Patent No. 5,885,561 and Japanese Patent Laid-Open No. -249525 discloses a technique for formulating natural waxes, mixed waxes in glass form or encapsulated in capsules and formulating the product. In the former case, the ceramide used is expensive and expensive to encapsulate, which is economically undesirable. In addition, since the capsule is secured in stability, even if the active ingredient is maintained in the capsule, when applied to the hair, it is difficult to adsorb and penetrate, so it is difficult to fully expect the effect. In the latter case, the natural wax is encapsulated in glass or capsules and formulated in a prescription. The wax is dissolved, cooled using an appropriate cooling device, then mixed mixtures are made, and then encapsulated in capsules and blended into the product. In addition to being complicated and expensive, there are limitations in providing a function of restoring hair health, such as increasing hair elasticity.

In order to solve the above problems, an object of the present invention is to prepare an intrinsically repairing damaged part in the hair including dialkyl carbonate and lipid components, give the hair shine, orderiness and softness, and also do not need to wash away It is possible to provide a hair cosmetic composition.
