Description

[Composition for Hair Care]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair care composition, and more particularly, to a composition for hair care which can be used for conditioning products, rinses, shampoos, and the like.

It is obvious that hair is a crucial part of man's appearance beauty as a face, and it is a decisive means of expressing man's life and image. In this sense, there has been continued research on a functional composition of Conditioning which can maintain not only basic cleaning function such as shampoo but also shiny and elastic hair. At the center of these researches is to provide consumers with the best hair condition by subdividing into a wet state (before use of the dryer) after cleaning, a state after drying, and a time to maintain the moisturizing state of the hair after drying . To achieve this purpose, new ingredients and compositions are developed and added to shampoos, rinses, conditioning products, and the like.

Especially, we are developing composition for new cationic surface active agent, high alcohol and high quality natural oil so that user can feel five senses such as moisturizing power, gloss, smooth touch and softness during rinsing. Korean Patent No. 1,351,473 discloses a new ammonium salt compound which is added together with a cationic surfactant in order to improve massage feel, rinse feel, softness in a wet state, and softness in a dry state. However, the effect was not improved as expected, and the quaternary ammonium salt did not significantly reduce the irritation of the scalp. Further, there was a problem that bubble power (degree of generation of bubbles) was lowered by adding silicon such as dimethicone.
