摘要:
New 4-substituted resorcinol derivatives of general formula I and/or B and process for synthesizing same, cosmetic compositions and methods of using same, particularly for skin lightening: Wherein X1 and/or X2 represents hydrogen (H), linear or branched, saturated or unsaturated C1-C12 alkyl, alkenyl, or acyl groups. Preferably, X1 and/or X2 represents hydrogen (H); linear or branched, saturated or unsaturated C1-C12 alkyl or acyl groups; R1 represents hydrogen (H), linear or branched, cyclic or acyclic, saturated or unsaturated C1-C12 alkyl, alkenyl, cycloalkyl, or cycloalkenyl group. Preferably, R1 represents hydrogen (H) or a C1 alkyl group (i.e, methyl group). More preferably, R1 represents hydrogen; n represents 0, 1. When n=0, the ring is a cyclopentyl with or without one heteroatom from O, N or S and/or with or without one double bond. When n=1, the ring is a cyclohexyl with or without one heteroatom from O, N or S and/or with or without one double bond; and m represents an integer between 1 and 6.

摘要:
A personal care product is provided which includes a composition a quaternary ammonium salt wherein a cation of the salt is a dihydroxypropyltri(C1–C3 alkyl)ammonium monosubstituted polyol in a carrier. The cation should have a molecular weight no higher than about 450 and the salt have a Tg no higher than about 10° C. Particularly preferred are hydroxypropyltrimonium sorbitol salts. These salts operate as humectants to moisturize both in high and low relative humidity environments.

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.
摘要:
Echinacea extract in cosmetic skin care compositions, as anti-irritant, to reduce skin irritation caused by hydroxy acids, and to boost the anti-aging efficacy of hydroxy acids.
摘要:
The present invention relates to novel hydroxy-containing alkyl glycamide surfactants and detergent composition comprising said surfactants. Since they surprisingly provide low foam, these surfactants can be used as cleansing surfactants in applications where low foaming is desirable.
