Sunscreens Based on Phenolic-Formaldehyde Particles
Sun-protective polymeric particles using a micro emulsion polymerization by nucleation approach have been developed by researchers at the University of Arizona. The resulting resorcinol-formaldehyde is red to brown in color with strong absorption of UVA and UVB radiation, making it an ideal material for sunscreen. Resorcinol-formaldehyde has been widely...

Sunscreens Prepared from Polydopamine and Poly (dopamine-co-cafeic acid)
This invention is synthetic eumelanin particles prepared by polymerization of dopamine that can be dispersed in water, glycerol or oil. Background: Sunscreen products in the market today are typically made of potentially harmful chemicals, including avobenzone, which releases cancer-causing free radicals, and oxybenzone, which has estrogenic properties...
