A kit includes a multi-phase oral composition for whitening teeth and an electromagnetic radiation source. The multi-phase oral composition for whitening teeth includes from about 0.002% to about 30%, by weight of the multi-phase oral composition, of a discontinuous aqueous phase having a bleaching agent, where a concentration of the bleaching agent is up to 10%, by weight of the multi-phase oral composition, and at least about 50%, by weight of the multi-phase oral composition, of a continuous hydrophobic phase of petrolatum. The electromagnetic radiation source is capable of directing electromagnetic radiation with one or more wavelength in the range from about 200 nm to about 1700 nm toward at least one tooth. The electromagnetic radiation source emits electromagnetic radiation in a range from about 100 mW/cm.sup.2 to about 250 mW/cm.sup.2.

Cosmetic compositions contain certain polylactic acid resins as film-formers. The polylactic acid resin is effective at low levels in the composition and is compatible with many organic ingredients commonly used in cosmetic compositions. The cosmetic composition can be formulated as a spray, a lotion, a cream or a paste.

Disclosed is a self-invertible inverse latex including, as an inverting agent, surfactant species of the polyglycerol ester family; the use thereof as a thickening and/or emulsifying and/or stabilising agent for a cosmetic, dermopharmaceutical or pharmaceutical topical composition, and cosmetic, dermopharmaceutical or pharmaceutical topical compositions containing same. Also disclosed is a new surfactant composition containing polyglycerol esters.

Provided is a powder material for a cosmetic that has excellent dispersibility in any of silicone oil agents, hydrocarbon oil agents, and ester oil agents, and does not affect the color appearance of a formulation. The powder material for a cosmetic contains a powder for a cosmetic surface-treated with an ester compound of a fatty acid having 8-20 carbon atoms and glycerol. The ester compound is at least one selected from the group consisting of diglyceryl tetraisostearate, diglyceryl triisostearate, glyceryl tri(caprylate/caprate), glyceryl dilaurate, glyceryl triisostearate, decaglyceryl monoisostearate, and decaglyceryl diisostearate.

This invention relates to a composition, in the form of a water-in-oil emulsion, containing: —at least 6% by weight in relation to the total weight of the composition, of at least one non-volatile hydrocarbon-based oil H1 chosen from plant oils or non-volatile triglycerides with a molecular weight greater than 400 Da, non-volatile non-polar hydrocarbon-based oils with a molecular weight greater than 350 Da, non-volatile ester oils with a molecular weight greater than 350 Da, and mixtures thereof; —optionally less than 5% by weight in relation to the total weight of said composition of non-volatile hydrocarbon-based oil(s) H2 chosen from C.sub.10-C.sub.26 alcohols, preferably monoalcohols; non-volatile triglycerides with a molecular weight less than or equal to 400 Da; non-volatile ester in oils with a molecular weight less than or equal to 350 Da; non-volatile non-polar hydrocarbon-based oils with a molecular weight less than or equal to 350 Da; dialkyl carbonates; and mixtures thereof; —at least 15% by weight of water with respect to the total weight of said composition; —at least one nonionic hydrocarbon-based or silicone surfactant; and —at least one polar hydrocarbon-based wax chosen from beeswaxes; synthetic beeswaxes; (poly)oxyalkylenated hydrocarbon waxes, the oxyalkykenated residue(s) being C.sub.2-C.sub.4 or (poly)glycerolated; alcohol waxes, and mixtures thereof.

A stable sprayable cosmetic composition that includes at least one mineral UV filter; at least one oil phase rheology modifier; and water; wherein the cosmetic composition is a water-in-oil composition and wherein the viscosity at shear rate of about 1000 (1/s) is lower than about 110 mPa.Math.s.

Topical personal care compositions containing amino acids and 4-substituted resorcinols for potentiating glutathione synthesis within skin cells. The compositions can be used to improve skin appearance of chronological aging or photoaging, resulting from exposure to UV light/sunlight, or environmental pollutants. The compositions are also useful for attaining even skin color and reducing pigmentation, age spots and discoloration.

The present invention relates to a water-in-oil surfactant consisting of a mixture of compounds of formula (I): ##STR00001##
wherein the compound of formula (I) has an average degree of polymerisation n of between 4 and 6,
R1, R2 and R3 being, independently of one another, a hydrogen atom or a group R4 derived from at least one carboxylic acid,
the carboxylic acid being 12-hydroxystearic acid or a mixture of 12-hydroxystearic acid and ricinoleic acid. The present invention also relates to a surfactant composition and to a cosmetic composition comprising this surfactant.

This invention relates to a process for preparing an inverse emulsion comprising mixing an aqueous solution comprising a water-soluble (co)polymer A synthesized from at least one cationic monomer and an inverse EMI 2 emulsion comprising a water-soluble (co)polymer B synthesized from at least one cationic monomer, optionally followed by distillation.
