Description

Hair conditioning composition with low viscosity

The present invention relates to a low-viscosity hair conditioning composition, and more particularly, to a low-viscosity hair conditioning composition excellent in room temperature stability and conditioning effect without using a lower alcohol.

Recently, as the standard of living has improved, interest in beauty is increasing, and hair beauty is also an important part of them. According to this trend, various hair beauty products such as dyeing products and perm products have been studied and commercialized.

However, frequent dyeing and perm may damage the hair, and the damaged hair is not shiny and is rough and difficult to prepare. Even in the case of healthy hair, if only shampoo is used, oil is removed from the hair due to excessive washing, and it is difficult to maintain calm hair due to insufficient gloss and static electricity.

In order to overcome this, conditioners in the form of emulsions composed of hair conditioning raw materials such as higher alcohol, cationic surfactant, water, and silicone are generally used. However, the conditioner of such an emulsion formulation has a disadvantage of slowing the penetration rate of the conditioning ingredient into the hair in the case of severely damaged hair.

For example, Korean Patent Laid-Open Publication No. 2003-0050371 discloses a conventional low viscosity hair conditioning composition containing water, lower alcohol, polyol, higher fatty alcohol and cationic surfactant in order to solve the above problems. . However, in such a hair conditioning composition, in order to maintain transparency at room temperature, a large amount of lower alcohol, especially ethanol, is used together with polyol. Since lower alcohol such as ethanol has the property of removing the lipid component of the hair, after drying There is a drawback that the hair becomes loose and less shiny.

Therefore, the problem to be solved by the present invention is to maintain stability at room temperature without the low-grade alcohol used for the room temperature stability of high-grade alcohol, thereby providing a soft touch and excellent gloss to wet hair as well as dry hair. It is to provide a composition.

In order to solve the above problems, the hair conditioning composition of the present invention includes a polyol having 3 to 5 carbon atoms having two or more hydroxy groups;

It is represented by the following formula 1

In Formula 1, n is a straight chain higher alcohol of 11 to 21;

It is represented by the following formula 2
