Description

Composition for hair care

The present invention relates to a composition for hair care. More specifically, the present invention relates to a hair care composition suitable for various hair products including hair conditioner, hair rinse, shampoo and the like.

This application claims that the Korean patent applications No. 10-2015-0006005, No. 10-2015-0006006 and No. 10-2015-0006007 filed on January 13, 2015 and all of them were filed on December 8, 2015 Priority of Korean patent applications No. 10-2015-0174301, No. 10-2015-0174305 and No. 10-2015-0174316 filed on Japan, the content of the Korean patent application is incorporated into this case for reference in its entirety Used for all purposes of this case.

Hair is similar to a person's face in importance. It is an important factor in determining a person's overall appearance and a key way for a person to express his vitality and image. Therefore, people have been developing hair care compositions that can not only cleanse the hair but also realize the care function of keeping the hair shiny and elastic. One of the most basic themes in these studies is based on different situations, such as when the hair is kept moist just after washing (before using a hair dryer) during shampoo, and after the hair is dry, moisturizing the hair to keep the hair at its best. Good condition. To this end, new ingredients and compositions have been developed and formulated into shampoos, conditioners and care products.

Specifically, the development of cationic surfactants, higher alcohols, and higher natural oils that allow users to feel that the hair has sufficiently high moisturization, gloss, smoothness and softness has always attracted attention. Korean Patent No. 1,351,473 discloses a novel ammonium compound that is used together with a cationic surfactant to broadly enhance the massage feeling of the hair, the touch during shampooing, and the smoothness of wet or dry hair. However, the degree of its enhancement did not reach the desired value, and due to the nature of quaternary ammonium, it was unable to significantly reduce the irritation to the scalp. In addition, the use of silicone resins such as dimethylpolysiloxane reduces the foaming ability (the ability to form foam).
