SunSpheres™ BIO SPF Booster

Award-Winning Bio-derived Biodegradable Sun Protection 

SunSpheres™ BIO SPF Booster is a biobased SPF booster from Dow made through the process of acid hydrolysis of wood pulp. This innovative new product works by a light scattering mechanism that offers effective UV scattering attributed to its high refractive index due to its high crystallinity, crystal size and agglomerate size.

SunSpheres™ BIO SPF Booster works as a natural SPF booster, functioning with both organic and inorganic UV filters with demonstrated in-vitro and in-vivo SPF boosting performance.


In addition to SPF Boosting properties, SunSpheres™ BIO SPF Booster also functions as a multifunctional ingredient, delivering stabilizing, thickening and shear thinning benefits.
