Title: Novel Material for Sunscreen - Synthetic Eumelanin Particles

 

Invention: 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 (Isabella Karlsson, 2009; StevenQ. 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 sunscreen that is safe for human use.

 

Applications:

  • Used for making sunscreen and other skin products

 

Advantages:

  • Inexpensive
  • Non-toxic
  • Mimic natural occurring compounds
