About
Sunscreens Prepared from Polydopamine and Poly (dopamine-co-cafeic acid) Tech ID: UA16-231 Invention: 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 highly absorbed by human skin. Instead of protecting us from sun damages, sunscreen products may actually increase cancer risks. This led the inventors to create a non-leaching sunscreen that is safe for human use.
Key Benefits
Inexpensive Non-toxic Mimic natural occurring compounds
