Problems solved by technology

[0018] In addition to using the above-mentioned silicone gel, there are known methods of adding silicone rubber powder or hydrophobic silicon dioxide or other powder that absorbs oil to low-viscosity silicone to control the viscosity or control the makeup film, but sometimes They give makeup an unwanted powdery feel like chafing, creases, etc.

Abstract

The present invention provides a composition for a cosmetic which has swellability with low-viscosity silicone oil and good affinity with other cosmetic oil agents and provides a cosmetic comprising the same. Present invention provides a composition for a cosmetic comprising a fluorine-containing silicone polymer having a three-dimensional, cross-linked structure, prepared by addition polymerizing the following (A), (B) and (C) and containing 10 to 30 mass % of the fluorine atoms, relative to a total mass of (A) to (C), (A) a vinyl group-containing organopolysiloxane represented by the following formula (1): (B) an organohydrogenpolysiloxane represented by the following formula (2): and (C) an organopolysiloxane having a reactive group on one end alone and represented by the following formula (3), and further comprising (D) a low viscosity silicone oil with a dynamic viscosity of 50 mm2 / s or less at 25 degrees C.

Description

technical field [0001] The present invention relates to a composition for cosmetics that provides cosmetics that have good affinity with other cosmetic materials and give cosmetics a very light and lubricious touch. Specifically, the present invention relates to a composition containing (silicone) oil has a swelling silicone polymer composition for cosmetics, and cosmetics containing the composition. Background technique [0002] Silicone oil is used as an oil agent for cosmetics because of its excellent characteristics such as dry touch, good stretchability, and good water repellency. Among them, low-viscosity silicone oils are often used to form non-sticky and light-touch cosmetics. [0003] Due to the compatibility of silicone oil with general oils and the poor affinity with thickeners, it is difficult to control the viscosity of low-viscosity silicone oils. As the viscosity control of these silicone oils, Or as a material for adjusting the film texture, there is a comm...
