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, depending on brand. Through the utilization of alkenes, this invention improves upon common commercial sunscreens by absorbing up to 400nm of UV rays.

Applications:

• Sunscreen
• Thin film coating on surfaces

Advantages:

• Protects skin and hair from UV rays
• Protects paints, plastics, woods or other UV sensitive surfaces
• Antioxidant characteristics extend lifetime of material
• Fluorescence can be used to determine if screen is functioning
