Naturally derived film former for water resistance

ABSTRACT

For a long time now, sunscreen formulations have utilized polymeric film formers to provide water resistance. In recent years, the concern about the film former impacting the environment has pushed the personal care industry for natural water resistance. Bis-octyldodecyl Dimer Dilinoleate/Propanediol Copolymer (BODP) is a naturally derived film former utilized in inorganic sunscreen formulations to provide water resistance. BODP also provides dispersant properties for ZnO and TiO2, thus reducing whiteness and provides the ability to apply inorganic particles onto wet skin.

 Sun care products are under a magnifying glass. American activists Environmental Working Group reported that the majority of sunscreens sold in the US contain chemicals that are deemed harmful to the environment.¹ This has led to the banning of specific sunscreen actives in Hawaii.²
