Abstract
The present invention is directed to a series of polymers containing end groups that are absorb ultraviolet (UV) light. The invention is also to the use of such compounds in the cosmetic, toiletry and personal care areas. These polymers can be utilized to produce films and provide solvent properties for the formulation of for ultra-violet absorbing formulations (like sunscreens) and provide outstanding dispensability and anti-agglomeration properties for inorganic sunscreens containing ZnO and TiO. The ability to provide uniform non agglomerating sun care formulations results in formulations with increase SPF values and improved 'water-resistant' properties in cosmetic formulation. The compounds of the present invention by themselves do not have ultra violet absorption at the particular wavelength that contributes to sun protection and consequently are not themselves sunscreens.
