Sunscreen composite particles and porous particles in cosmetic compositions

Abstract

A cosmetic composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, a water-insoluble powdered polymer of porous particles having an Oil Absorbance (castor oil) Value ranging from 90 to 500 ml / 100 gm, and a cosmetically acceptable carrier. The composition exhibits an excellent soft focus property to hide skin imperfections, and retains relatively high SPF photoprotection.

Description

technical field

[0001] The present invention relates to cosmetic sunscreen compositions providing UV protection and soft focus properties. Background technique

[0002] Ultraviolet radiation can damage the skin. The immediate damage is in the form of redness of the skin. More long-term is the problem of triggering cancerous growths. For these reasons, photoprotective agents known as sunscreens have been introduced into cosmetic products.

[0003] Facial cosmetics are ideal not only to provide photoprotection but also to improve the overall skin appearance. Most people have facial imperfections. These can include uneven tone, large pores, fine lines and wrinkles.

[0004] Soft focus is an effect that hides imperfections in the skin. Incident light is distorted by scattering (lensing). The particle components of cosmetics work like lenses, bending and twisting light in all directions.
