MicroDelivery UV filter microcapsules are developed by our unique formula to coat different kinds of organic UV filter.
On June 1, 2016, CFDA (China Food and Drug Administration) issued new regulations: SPF(Sun Protect Factor) identifies are allowed to be a maximum of 50 +, protective effect of long-wave ultraviolet (UVA) identifies can reach the highest PA++ + + ,which means the era of the highest SPF of 30 + is finally over. According to the new regulations, in order to improve the SPF and protective effect, many companies want to increase the content of organic UV filter of product, which increases the risks to skin because of infiltration of UV filter monomer. Ultimately, these will lead to a growth of toxicity and cost of product.
The polymeric structure of UV filter capsules shell can not only prevent the UV filer from light degradation, it also can increase the SPF, improve the skin-touch and gain better waterproof properties of product, more importantly, the capsule provide the best way to isolate skin with toxic substances, which is significant when applied to sunscreen, segregation frost and other kinds of makeup products, as well as fiber textiles such as protective clothing, etc.
Main performances of MicroDelivery UV filter microcapsules:
Avoid toxicity: avoid the toxicity caused by UV filter soak into the skin.
Improve the SPF value: the SPF of products using UV filter microcapsules can be increased by more 90% than the pure equivalent UV filter products.
Improve waterproof performance: microcapsules can be easily dispersed in formula of products such as sunscreen, which can greatly improve the waterproof performance of sunscreen on the skin surface.
These products are in the international leading level (all the test report conclusions relating to MicroDelivery
UV filter microcapsules are confirmed by L 'oreal American headquarters) , as it were, which fill the domestic blank.
