Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an emulsified cosmetic composition for hair.

[0002]

2. Description of the Related Art In the case of styling hair, hair oil and pomade are excellent in the effect (setting power) of pressing and fixing the hair to fix the hair, but it is not possible to give a soft and proper cohesion. However, it had the drawback of giving a greasy or sticky feeling. On the other hand, water-soluble hair cosmetics prepared by suspending an oily component in water using various surfactants have less stickiness than hair oils and pomades, but have a style-retaining power as water evaporates. It had the drawback of falling. In addition, regarding the water-soluble hair cosmetics, although the style-retaining power is improved by blending a polymer substance, it has the drawbacks that it tends to be stiff, loses the flexibility of the hair, and has poor restyling properties. It was

In order to solve these drawbacks, hair cream and hair wax, which are oil-in-water type emulsified cosmetics obtained by emulsifying a relatively high content of oil, have been created in recent years. However, these emulsion-type cosmetics have a drawback that they give a sticky feeling, although they can suitably impart a soft and appropriate cohesion to the hair.
