Abstract: Disclosed is a UV absorber mixture, comprising (a) 1% to 60% of a micronised UV broadband absorber of formula: Formula (I); wherein R1 is C1-C12alkyl; or phenyl-substituted C1-C12alkyl; and (b) 1% to 60% by weight of a water dispersible and/ir oil-dispersible coated titanium di-oxide.

Abstract: Disclosed is a topically applicable water-in-oil (w/o) or water-in-silicone (w/Si) formulation comprising: (a) at least one aqueous phase; (b) at least one fatty phase; (c) an effective UV-photoprotecting composition comprising (c1) 20% to 99% of at least one insoluble micronized organic UV-screening active with a mean particle size ranging from 0.01 ?m to 2 ?m; and (c2) 0.5% to 80% of at least one primary C6-C28 fatty alcohol. The combination of a micronized organic UV absorber and a specific fatty alcohol allows a maximum of miscibility of micronized organic particles within the continuous oil phase of w/o emulsion wherein the micronized particles are stabilized in the oil phase of the composition. Simultaneously the crystal growth of micronized organic UV absorbers within W/O emulsions is limited or even eliminated.

Abstract: The present invention relates to new UV-protection formulations with improved stability in respect to crystallisation, characterized in that a compound of formula (1) or a mixture thereof wherein R1 is substituted or unsubstituted C6–C12alkyl, R2, R3 and R4 are independently from each other hydrogen; substituted or unsubstituted C1–C4alkyl, preferably hydrogen; unsubstituted C1–C2alkyl or substituted C1–C2alkyl, more preferably hydrogen. is added to the UV-protection formulation.

Abstract: Disclosed is a UV absorber mixture, comprising (a) 1% to 60% of a micronised UV broadband absorber of formula: Formula (I); wherein R1 is C1-C12alkyl; or phenyl-substituted C1-C12alkyl; and (b) 1% to 60% by weight of a water dispersible and/ir oil-dispersible coated titanium di-oxide. The UV absorber mixture shows synergistic effect with respect to the UPF.
