Title: Novel Material for Sunscreen - Co-polymerized Phenols with Aromatic and Cojugated Aldehydes


Invention: Particles that can be used as sunscreens prepared by the copolymerization of phenols with aromatic and conjugated aldehydes like cinnamaldehyde or benzaldehyde. These particles made of biobased materials can be dispersed in liquid and function as thermosets for sun-blocking purposes.


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 (Isabella Karlsson, 2009; Steven !. Wang, et al., 2011). Instead of protecting us from sun damages, sunscreen products may actually increase cancer risks. Therefore, the inventors set out to create non-leaching set out to create non-leaching sunscreen that is safe for human use.
