Description

TECHNICAL FIELD The present invention relates to a composition for protecting hair from heat,

The present invention relates to a hair protecting composition, and more particularly to a composition for protecting hair from heat comprising amodimethicone and a dimethicone / vinyl dimethicone crosspolymer as an active ingredient. will be.

In modern society, which emphasizes cosmetics, hair is often damaged by various physical, chemical or environmental factors such as perms, staining, and so on. In particular, a consumer who uses a hair iron or a hair dryer every day may suffer hair damage due to a hot air balloon. In order to prevent the damage of the hair from being accelerated, it is necessary to use a hair product to prevent damage before using the hot air balloon.

However, conventional hair essence is limited to impart softness of hair, and there is a limit to protect hair from continuous use of high-temperature hair dryer or hair dryer. The conventional hair essence is a combination of dimethicone gum and cyclomethicone. The essence of this essence is that since the spread of dimethicone is low when the hair is applied to the hair, the moisture inside the hair is well preserved And it has been difficult to effectively prevent hair damage due to a hot air balloon. Therefore, there is a demand for development of a product that can effectively protect hair even by strong heat.

Under these circumstances, the inventors of the present invention have made extensive efforts to develop a composition capable of maintaining moisture inside the hair and preventing hair from being damaged even by strong heat. As a result, a combination of amodimethicone and dimethicone / vinyl dimethicone crosspolymer The present inventors have confirmed that the use of other silicones and the effect of protecting the hair from heat are superior to those of the conventional products.

Korean Patent Publication No. 10-2006-0018985 (published on Mar. 3, 2006)

It is an object of the present invention to provide a hair protecting composition.

Another object of the present invention is to provide a quasi-drug composition for hair damage prevention.

It is yet another object of the present invention to provide a method of preventing damage to hair from heat comprising applying the composition to the hair.

In one aspect of the present invention, there is provided a cosmetic composition for hair care comprising amodimethicone and a dimethicone / vinyl dimethicone crosspolymer as an active ingredient. do.

Amodimethicone as an active ingredient in the composition of the present invention can be represented by the following formula (1)

[Chemical Formula 1]

x is an integer of 1 or more and 1000 or less.

The dimethicone / vinyl dimethicone crosspolymer, which is included as an effective component in the composition of the present invention, is a polymer in which dimethicone and vinyl dimethicone are cross-linked. Specifically, the dimethicone / vinyl dimethicone crosspolymer has a structure of the following formula .

(2)

Wherein R ₁ to R ₃ are each independently -CH ₃ or -CH═CH ₂ and at least one of -CH ₃ and -CH═CH ₂ is present,

x is an integer of 1 or more and 1,000 or less.

Silicone has a hair conditioning effect and has been widely used in existing hair products. Conventionally used hair essences include dimethicone and cyclomethicone, but they have low spreadability in hair and have a problem of water loss due to a hot air balloon. In particular, there was no case in which amodimethicone and dimethicone / vinyl dimethicone polymer were mixed to prevent hair damage due to hot air ballooning. Also, in the present invention, it has been confirmed that when a mixture of amodimethicone and dimethicone / vinyl dimethicone crosspolymer among a large number of silicones is known, the hair protecting effect is excellent and the effect of protecting hair damage due to heat is high.
