Abstract

The present application belongs to the field of cosmetic technology, and specifically relates to a sunscreen synergistic composition, sunscreen cosmetics and applications. The present application provides a new type of sunscreen synergistic composition by selecting four components, namely RonaFlair®LDP White, silk powder, ergothioneine and acrylic acid (ester) / ethylhexyl acrylate / polydimethylsiloxane methacrylate copolymer, and scientifically proportioning them. The sunscreen synergistic composition can be applied to sunscreen cosmetics to synergistically enhance the sunscreen effect of sunscreen agents, reduce the types and amounts of sunscreen agents in sunscreen cosmetics, have broad market value and application prospects, and have unexpected technical effects. The present application also selects dipentaerythritol pentaisostearate as the fifth component of the sunscreen synergistic composition. This component can be matched with the above four raw materials, and by controlling its addition amount, the comprehensive sunscreen effect of the product can be significantly improved.
