Embodiment

[0184] Hereinafter, although an Example and a comparative example are shown, and this invention is concretely demonstrated, this invention is not limited to a following example.

[0185] First, Synthesis Examples 1 to 15 of polymers were prepared for use in Examples and Comparative Examples. Synthesis Examples 1 to 8 are paste compositions containing polymers of organohydrogenpolysiloxane and polyoxyalkylene, and Synthesis Examples 9 to 15 are paste compositions containing polymers of organohydrogenpolysiloxane and polyglycerin .

[0186]

[0187] First, synthesis examples 1 to 8 of polymers containing organohydrogenpolysiloxane and polyoxyalkylene will be described.

Synthetic example 1

[0189] In the reactor, the average composition formula is 324.2 g of organohydrogenpolysiloxane shown in formula (1), the average composition formula is 53.8 g of polyoxyalkylene shown in formula (2), and the viscosity at 25°C is 6mm 2 162.0 g of dimethyl polysiloxane per s, 270.0 g of ethanol, and 0.3 g of a 3% by mass chloroplatinic acid ethanol solution, the internal temperature was maintained at 60 to 70° C., and after stirring for 2 hours, the solvent was removed by reducing pressure. , to obtain a cross-linked silicone polymer.

[0190] Next, 50 parts by mass of this cross-linked silicone polymer and a viscosity of 6 mm at 25° C. 2 / s of 90 parts by mass of dimethylpolysiloxane was dispersed and mixed, and then sufficiently kneaded under shear force by a three-roll mill to swell to obtain a paste composition.

Abstract

According to the present invention, provided is a cosmetic having a high stability, larger degree of change in feeling by an oil phase and a water phase when the cosmetic is coated on the skin, and long time until change in feeling is found. A cosmetic comprising a polymer (A) having a content of an oxyalkylene unit and / or a glycerin unit of 0.5% by mass or more and under 5.0% by mass; and a polymer (B) having a content of an oxyethylene unit and / or a glycerin unit of 5.0% by mass or more and 20.0% by mass or less, the polymer (A) and the polymer (B) being a crosslinking organopolysiloxane polymer obtained by reacting organohydrogen polysiloxane having two or more hydrogen atoms bonded to a silicon atom in one molecule and polyoxyalkylene and / or polyglycerin having two or more aliphatic unsaturated bonds in one molecule, wherein the mass ratio of the polymer (A) to the polymer (B) is 5:95 to 60:40.

Description

technical field [0001] The present invention relates to a cosmetic material containing a crosslinked organopolysiloxane having a hydrophilic functional group. Background technique [0002] Conventionally, silicone oil has been used as a base oil for various compositions in various fields such as cosmetics because of its safety and the like. Especially in cosmetic skin care, make-up and other uses, 100mm 2 Low-viscosity silicone oils below / s are widely used because of their excellent spreadability, refreshing feeling, and high safety. [0003] However, when using low-viscosity silicone oil as a base oil to adjust, for example, a paste composition without fluidity, it is necessary to use dextrin fatty acid esters (Patent Documents 1 to 4), sucrose fatty acid esters (Patent Document 5 ), trimethylsilylated polyvinyl alcohol and trimethylsilylated polysaccharides (Patent Document 6), organic materials such as cellulose ethers containing fatty acid ester groups (Patent Documen...
