Abstract
Complexes of .beta. carotene with cyclodextrin are described, having reduced color intensity and a shift of color to tones more neutral than the deep red of uncomplexed .beta. carotene. When these complexes are added to topical compositions such as typical skin cream bases in amounts up to 1.0% .beta. carotene w/v, the result is a cream having a pinkish to beige color which is cosmetically acceptable, as opposed to the mustard orange to red color seen in creams containing like amounts of uncomplexed .beta. carotene.
