Abstract: Disclosed are extracts of Nigrospora sphaerica as cosmetic skin benefit agents, preferably as skin lightening agents alone or in combination with other skin benefit agents and together with a cosmetic vehicle. The inventive extracts, compositions and methods have effective skin lightening properties, may be easier to deliver to the skin, and are commercially available or cost-effective and available in nature.

Abstract: Disclosed are coumarin derived compounds of formula I as skin lightening agents alone or in combination with other skin benefit agents and together with a cosmetic vehicle: Where each or both R1 and/or R2 represents hydrogen (H); linear or branched, saturated or unsaturated C1-C12 alkyl, alkenyl, acyl, or heteroalkyl (preferably, alkoxy) groups; and R3 represents linear or branched, cyclic or acyclic, saturated or unsaturated C1-C12 alkyl, alkenyl, cycloalkyl, cycloalkenyl, or heteroalkyl group; and R4 represents a hydrogen atom (H); straight or branched, cyclic or acyclic, saturated or unsaturated, containing or not containing a heteroatom C1-C22 alkyl, alkenyl, cycloalkyl, cycloalkenyl, heteroalkyl, aryl, or heteroaryl group.

Abstract: Cosmetic compositions and methods of skin lightening using compounds of formula I as skin lightening agents: Wherein X represents Carbon, Nitrogen, Sulfur or Oxygen; each A1 and/or A2 independently is =H or COR, CO2R, CONHR having the following formula A: where R=C1-C18 saturated or unsaturated, linear or branched, hydrocarbon; and each Y1 and/or Y2 independently is C1-C18 saturated or unsaturated hydrocarbon or OZ, where Z=H or COR1, CO2R1, CONHR1 of formula B: and where R1=C1-C18 saturated or unsaturated, linear or branched, hydrocarbon.

Abstract: Cosmetic compositions containing organic sunscreens along with a 4-substituted resorcinol derivatives of general formula I exhibit improved storage stability and oxidative stability: where each R1 and R2, independently, represents a hydrogen atom, —CO—R (acyl group), —COO—R CONHR; where R represents saturated or unsaturated, linear, branched or cyclic C1-C18 hydrocarbon groups; and R3 represents (1) an alkyl group, having from 1 to 18 carbon atoms, preferably having from 2 to 12 carbon atoms, with or without substitution of one or more hydrogen atoms of a linear alkyl group with a methyl or ethyl group; e.g., R3 constitutes linear or branched chain alkyls, or (2) a group of the general formula formula (II) Where X is preferably H, n is 0 to 3 and the dashed lines represents an optional double bond.
