1 1 Why is Photostability Important?

2 2 Biggest Innovation in UVA Protection has Been the Invention of Avobenzone Avobenzone provides broad spectrum beyond 370 nm 290 Wavelength (nm) 2.5 1.5 1 0.5 0 2 310330350370390 Absorbance With avobenzone With oxybenzone Data on file, Johnson & Johnson Neutrogena.

3 3 An Example of Avobenzone Photoinstability in a Sunscreen Formulation Wavelength (nm) Absorbance 290310330350370390 Static SPF 10 J 20 J 50 J 2.0 1.8 1.6 1.4 1.2 1.0 0.6 0.4 0.2 0 0.8 Data on file, Johnson & Johnson Neutrogena.

4 4 Why is Photostability Important? Photostable and non-photostable spf products have the same protection up to their SPF value, but protection after first MED is very different

5 5 How Can You Tell Which Ones Are Photostable? Currently, there is no uniform test method or communication device on products to indicate photostability of products or extent of UVA protection

6 6 Helioplex ™ Technology

7 7 What Comprises Helioplex ™ Technology? Photostable UVA –Contains avobenzone—provides broad UVA protection –Contains diethylhexyl 2,6-naphthalate (DEHN)— an avobenzone stabilizer –Contains benzophenone (oxybenzone, sulisobenzone, or dioxybenzone)—stabilizes avobenzone and adds UVA protection Added SPF drivers – Conventional UV filters to build SPF Data on file, Johnson & Johnson Neutrogena.
