Description

Composition for hair care {Composition For Hair Care}

The present invention relates to a composition for hair care, and more particularly, to a composition for hair care that can be used for conditioning products, conditioners, shampoos, and the like.

Hair is an important part of a person's appearance as well as a face, and it is obvious that it is a crucial means of expressing a person's vitality and image. In this sense, studies on functional compositions of conditioning that can maintain shiny and elastic hair as well as basic cleaning functions such as shampoos have been continued. The focus of these studies is to provide consumers with the best hair condition by subdividing them into conditions such as during washing, slightly wet after washing (before using a dryer), after drying, and the time to keep the hair moisturized after drying. To do. To achieve this purpose, new ingredients and compositions are developed and added to shampoos, rinses, and conditioning products.

In particular, we are developing compositions for new cationic surfactants, high-quality alcohols, and high-quality natural oils so that users can feel the moisturizing power, gloss, smooth touch, and softness during rinsing with the five senses. Korean Patent No. 1,351,473 has developed a new ammonium salt compound and added it together with a cationic surfactant in order to improve overall the feeling of massage during use, the feel of rinsing, the softness of a wet state, and the softness of a dry state. However, the effect did not improve as expected, and due to the nature of the quaternary ammonium salt, it did not significantly reduce the scalp irritation. In addition, as silicon such as dimethicone is added, there is a problem in that the bubble power (the degree to which bubbles are generated) decreases.

Conditioner composition with excellent hair softness and smoothness (Korean Patent Publication No. 10-1351473)

Accordingly, the applicant of the present invention has conducted various studies to solve the above problem, and as a result of preparing a polymer in which a polar polymer and an unsaturated fatty acid are chemically bonded, this polymer is used as an additive with a cationic surfactant and a higher fatty alcohol.
