Description

[0001] Hair conditioning composition with low viscosity [0002]

The present invention relates to a low viscosity hair conditioning composition, and more particularly to a low viscosity hair conditioning composition having excellent room temperature stability and conditioning effects without the use of lower alcohols.

Recently, as the level of living has improved, interest in beauty has been increasing, among which beauty of hair is also an important part. According to this trend, a variety of hair cosmetic products such as dyed products and permanent products have been researched and commercialized.

However, frequent dyeing, permanent hair can damage hair, and damaged hair has no gloss, is slippery, and hair is difficult to trim. In 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 lack of gloss and static electricity.

In order to overcome this, an emulsion type conditioner composed of a hair conditioning material such as a high-alcohol, a cationic surfactant, water or silicone is generally used. However, these emulsion-type conditioners have the disadvantage that the penetration rate of the conditioning component to the hair is slow in severely damaged hair.

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

Accordingly, a problem to be solved by the present invention is to provide a low-viscosity hair conditioner capable of maintaining stability at room temperature without lower alcohol used for room temperature stability of high-quality alcohol, and capable of imparting smooth feeling and excellent gloss to dry hair as well as wet hair Compositions.

In order to solve the above problems, the hair conditioning composition of the present invention comprises a polyol having 3 to 5 carbon atoms and having at least two hydroxy groups;
