摘要:
Leave-on non-solid skin conditioning compositions containing 12-[(12-hydroxyoctadecanoyl)oxy]octadecanoic acid. 12[(12-hydroxyoctadecanoyl)oxy]octadecanoic acid can be easily incorporated in combination with lipophilic carriers that are liquid at room temperature. Compositions are able to deliver increased energy production by human fibroblasts. Preferred compositions also contain 12-hydroxy stearic acid and thus are able to deliver a wide range of skin benefits.
摘要:
A personal care composition is provided which includes a trihydroxy and quaternary ammonium substituted dipropyl ether. The substituted dipropyl ether functions as a humectant when applied to human skin to moisturize both in high and low relative humidity environments.

Compounds of formula I, process for making same, and cosmetic compositions and methods of skin lightening using compounds of formula I as skin lightening agents: Where each A1 and/or A2 independently is ═H or COR, CO2R, CONHR, the latter three having the following formula A: where R═C1-C18 saturated or unsaturated, linear or branched, hydrocarbon; and each Y1 and/or Y2 independently is H; 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; X is Carbon, Nitrogen, Sulfur, or Oxygen; and N is in integer between 0 and 2.
摘要:
Certain novel substituted 3-(phenoxymethyl) benzyl amines and personal care compositions comprising such, which are particularly beneficial for skin lightening and achieving evenness of color, especially for face and underarm skin.
摘要:
A personal care product is provided which includes a composition containing dihydroxypropyltri(C1-C3 alkyl)ammonium salt in a carrier. The composition is packaged for delivery to a consumer and includes instructions printed on or associated with the packaging indicating topical use of the composition on skin, hair or the oral mucosae. Particularly useful is dihydroxypropyltrimonium chloride which operates as a humectant to moisturize both at high and low relative humidity environments.
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:
Process for carboxy-alkylation, particularly carboxymethylation, of branched alcohols includes the reaction of isoalcohols with potassium-t-butoxide or sodium-t-butoxide and with salt of halogenated alkanoic acid in the presence of the isoalcohol (starting alcohol) as the solvent. Produced are isoalcohol carboxy-alkylates (preferably, carboxymethylates) in excellent yields and purity.
