Mixed n-butyl and iso-propyl phthalamide compounds as sunscreen solubilizers

摘要: The present invention is directed to a high active sunscreen composition for topical application human skin protect the against UV radiation damage. particularly suitable over-coating with make-up or other cosmetic compositions. More particularly, use of specific eutectic mixture lower alkyl phthalamide that surprisingly effective in solubilizing 4-(1,1-dimethylethyl)-4′-methoxydibenzoylmethane (PARSOL.RTM. 1789). Such concentrates solutions PARSOL.RTM. 1789 can be used formulate more sunscreen, having increased protection factor (SPF) and such over longer period time so need not applied as frequently.
