Particulate and Film Polymeric Dihydropyridazines as Sunscreens with Inherent Antioxidant Properties
This invention is a polymeric sunscreen that can be applied either as a film or as particles to be suspended in either water or oil.
Background:
Both UVB and UVA wavelengths penetrate the atmosphere, inducing skin cancers, eye damage and aging if not properly protected or treated. Common commercial sunscreens can block around 93% of UVB and UVA rays,...

Dihydrotetrazine Antioxidants and Free Radical Reaction Inhibitors
This invention is the use of dihydrotetrazines as antioxidants to eliminate free radicals. Dihydrotetrazines were found to be superior to dihydropyridazines or hindered phenols in inhibiting free radical polymerization.
Background:
Dihydrotetrazines donate up to two hydrogen atoms to terminate radical chain or oxidation reactions. These compounds...
