Description

COSMETIC COMPOSITION OF SHERBET-BALM FORM COMPRISING BUTTER WITH LOW MELTING POINT comprising low melting point butter [

The present invention relates to cosmetic compositions of sherbet-chestnut formulations comprising low melting point butter. Specifically, the present invention relates to a cosmetic composition comprising a low melting point butter and having excellent stability even at low temperature storage or high temperature conditions, and further having excellent spreadability, feeling of use, and moisturizing power.

Generally, cosmetic products mostly use fatty alcohol or wax to form high hardness cream. Cosmetics such as some commercially available lotions, essences, and creams are produced in high hardness products, but they are problematic in that they are poor in spreadability. In particular, in the case of cream formulations, most of the wax raw materials are used in order to improve the feel and moisturizing effect, but the viscosity and hardness are rapidly increased and the wettability is great, so that it is difficult to use the cosmetic.

Korean Patent Laid-Open Publication No. 2015-0050303 discloses a low viscosity cosmetic composition containing a low melting point butter or a wax. Particularly, the above patent discloses a constitution in which a low melting point butter or a waxy raw material having a melting point of 40 캜 or lower is used in an amount of 0.5 to 20% by weight. However, the above patent does not describe a formulation having a high hardness.
