  • Mixed n-butyl and iso-propyl phthalamide compounds as sunscreen solubilizers
    Patent number: 6306373
    Abstract: The present invention is directed to a high active sunscreen composition for topical application to human skin to protect the skin against UV radiation damage. The composition is particularly suitable for over-coating with make-up or other cosmetic compositions. More particularly, the present invention is directed to the use of a specific eutectic mixture of lower alkyl phthalamide that is surprisingly effective in solubilizing 4-(1,1-dimethylethyl)-4′-methoxydibenzoylmethane (PARSOL.RTM. 1789). Such concentrates solutions of PARSOL.RTM. 1789 can be used to formulate a more effective sunscreen, having a surprisingly increased sunscreen protection factor (SPF) and such that the PARSOL.RTM. 1789 is more effective over a longer period of time so that the sunscreen composition need not be applied to the skin as frequently.
