Composition containing a cellulose derived capsule with a sunscreen
A sunscreen composition comprised of one or more sunscreen active agents encapsulated in a cellulose derived capsule wherein the composition can contain one or more additional agents. A sunscreen composition can be mixed with a bodywash, shampoo, conditioner, lotion, gel, soap, cream, hand sanitizer, spray or mousse and can be used by an individual during their normal hygiene processes, such as during a shower or bath or while applying a body product to their skin or hair.
