Problems solved by technology

Summarizing these patents, it is not difficult to find that most of them start from the combination of sunscreen raw materials to improve the sunscreen performance, and seldom consider the influence of other components (base materials) in the entire composition of cosmetics on the SPF. Secondly, the current patents From the point of view, in order to obtain a sun protection factor (SPF value) with a sun protection factor greater than 30, the mass fraction of the added sunscreen agent must account for at least 12% of the content (100%) of the entire cosmetic composition (formula)

Abstract

The invention provides sunscreen cosmetic composition. A sunscreen raw material substrate combination coated with hydrogenated lecithin W / O / W double-layer microspheres is subjected to secondary preparation, and the sunscreen cosmetic composition is obtained and comprises glyceryl stearate & PEG-100 stearate, cetearyl alcohol & cetearyl glucoside, cetearyl alcohol, shea butter, kukui oil, isooctyl palmitate, polysiloxane and other proper auxiliaries. The SPF (sun protection factor) of the sunscreen cosmetic composition exceeds 35 under the condition that the total mass fraction of the sunscreen components is smaller than or equal to 12%.

Description

technical field [0001] The invention relates to a sunscreen cosmetic composition obtained by using a "sunscreen raw material base combination" coated with lecithin W / O / W double-layer microspheres and then secondary preparation. Background technique [0002] The development of sunscreen cosmetics with high sun protection factor (SPF value) has always been a hot issue for cosmetic workers, especially adding a small amount of sunscreen to make cosmetics obtain high sunscreen performance has always been the direction and difficulty of researchers. Traditionally, it is By adding a large amount of sunscreen to obtain high sunscreen performance (indicated by a high SPF value), there are many problems in this method, such as the addition of a large amount of sunscreen will make it difficult to control the formulation, stability, and skin feel of cosmetics; some Chemical sunscreens have high penetration and absorption in the case of high content, which will greatly increase the risk ...
