Anti-UV microcapsules are anti-UV products acquired by encapsulating UV-light protective agent with encapsulation technology.According to the latest regulations released by China Food and Drug Administration on June 1, 2016, the highest mark for domestic sun protection factor (SPF) is increased from 30+ to 50+, and the highest mark for ultraviolet a (UVA) protecting effect is stipulated as PA++++. In order to meet the requirements in the new regulations, so as to increase the SPF index and the protecting effect, it is required to add more ultraviolet absorber monomer compounds with risks of penetration into skins, leading to increased toxicity and product cost.

Avoiding toxicity: The products can avoid toxicity generated by permeation of UV-light protective agent into skin effectively.

Increasing waterproofness: Microcapsules are easy to be dispersed in product ingredients such as sun creams, which greatly improve the waterproofness of sun creams on surface of skins.
