Abstract:

With the vigorous development of color cosmetics, physical powder has been more and more widely used because it can adjust the spread, absorption, skin adhesion, texture, and fade the visual focus of cosmetics. It is applied more and more widely in all fields, covering skin care, sunscreen, make up, and is paid more and more attention by beauty brands. In this paper, silica, talcum powder, mica powder, polymethyl methacrylate, polymethylsilsesquioxane, silicon elastomer powder, nylon powder, polyurethane powder and starch were briefly introduced. The surface morphology, particle size, oil absorption value and skin feeling’s characteristics of the above powders were summarized, and the application status of skin feeling improved powders was described. Silica, as a spherical powder with smooth skin and high hardness, can absorb oil and water; talc is a layered structure with a certain covering power and strong adhesion; mica is flake structure with outstanding skin adhesion and luster; polymethylmethacrylate is softer than silica and can selectively absorb sebum; polymethylsesimiloxane is a matte spherical powder with uniform particle size distribution; silicon elastomer powder is a spherical powder with strong oil absorption, good soft coking effect; nylon’s hardness is lower than polymethylmethacrylate and its skin feel is soft; polyurethane’s hardness is lower than nylon and it has strong elasticity and cushion feeling; starch has strong smoothness and can reduce the greasy feeling. Then the characteristics of composite powder and traditional powder are compared. With the continuous development of the market, the additional performance of composite powder can better meet the higher requirements of modern cosmetics in skin feeling and efficacy. Finally, the development trend of improved skin feeling powder was predicted. The experience of composite powder is more refined, and the pertinence is stronger. When choosing the skin feeling improved powders, it is not only necessary to comprehensively consider the surface morphology, particle size, oil absorption value and skin feeling characteristics of the powder, but also the multi-functional composite powder will play an increasingly important role in future.
