Method for treating hair comprising the successive application onto hair of polymeric layers which can be removed to a large extent or even totally in an easy manner upon request of the user by using a cationic surfactant.

This application provides, among other things, novel aqueous monophasic compositions useful for combining and delivering poorly compatible ingredients, for example to deliver effective levels of cationic antibacterial agents in combination with anionic polymers, e.g. that protect against erosion and staining, by addition of a stabilizing amount of a polyamine, e.g. lysine, and methods for making and using the same.

A volatile oil composition includes a vehicle and a silicone elastomer, wherein the vehicle is a volatile oily composition of (a) from 50 to 100% by weight of a mixture of linear paraffins including (i) 90 to 99% by weight of at least one linear paraffin selected from C.sub.8, C.sub.10, C.sub.12 paraffins and mixtures thereof, and (ii) 1 to 10% by weight of a C.sub.14 linear paraffin, and (b) from 0 to 50% by weight of at least one non-volatile oil. The composition may be used in cosmetic compositions such as for making up and/or caring for and/or protecting skin, lips, eyelashes and/or nails, and in antiperspirant/deodorant compositions.

Disclosed is a self-invertible inverse latex having an aqueous phase, including: a) a cross-linked anionic polyelectrolyte (P) including:—at least one first monomer unit derived from 2-methyl-2-[(1-oxo-2-propenyl)amino] 1-propane sulfonic acid in the form of a free or partially or totally salified acid; and—at least one second monomer unit derived from at least one monomer selected from the elements of the group consisting of (2-hydroxyethyl)acrylate, (2,3-dihydroxypropyl)acrylate, (2-hydroxyethyl)methacrylate, (2,3-dihydroxypropyl)methacrylate, or vinylpyrrolidone; and—at least one monomer unit derived from a cross-linking polyethylenic monomer (AR); b) at least one chelating compound (SQ) selected from the elements of the group consisting of ethylenediamine disuccinic acid in the form of trisodium salt, tetrasodium salt of glutamic acid, N,N diacetic, or the sodium salt of imminosuccinic acid.

Disclosed is a dental bleaching gel composition with high electric conductivity. It was the object of the present invention to provide a bleaching gel composition that is less initiating than prior art gels, and is highly efficient such that it can bleach within shorter time. The composition includes a peroxide, or a peroxide releasing compound such as carbamide peroxide, sodium perborate, or sodium percarbonate as a bleaching agent, a cross-linked polyacrylate polymer as a thickening component, and electrical conductivity enhancing ingredients such as electrolytes.

The present invention relates to an oil-in-water emulsion gel cosmetic composition comprising an oil agent, water, a polyol, an anionic surfactant, an amphiphilic polymer and a coloring material.

The present invention relates to a hair cosmetic composition, especially for washing and/or conditioning hair, comprising surfactants and an oil-in-water emulsion that comprises: a silicone mixture comprising a trialkylsilyl terminated dialkylpolysiloxane and an amino silicone; a mixture of emulsifiers comprising one or more nonionic emulsifier, wherein the mixture of emulsifiers has a HLB value from 10 to 16; and water.

The invention also relates to a process for the cosmetic treatment of hair, preferably for washing and/or conditioning hair, using this composition.

Provided are hair treatment compositions comprising one or more polysaccharides and their use in improving hair strength.

The purpose of the present invention is to provide an oil-in-oil emulsified cosmetic having exceptional transfer resistance after application, luster, excellent spread during application, and especially exceptional cosmetic durability. The present invention pertains to an oil-in-oil emulsified cosmetic characterized by containing (a) 5-80 mass % of a nonvolatile hydrocarbon oil and/or nonvolatile ester oil, (b) 1-70 mass % of a nonvolatile silicone oil, and (c) 2-12 mass % of a spherical powder having an average particle size of 1-10 μm, the oil-in-oil emulsified cosmetic moreover being characterized in that the (a) nonvolatile hydrocarbon oil and/or nonvolatile ester oil and the (b) nonvolatile silicone oil separate when mixed at 25° C. The blend ratio (mass ratio) of the (a) nonvolatile hydrocarbon oil and/or nonvolatile ester oil and the (b) nonvolatile silicone oil is preferably (a)/[(a)+(b)]=0.4-0.8.

Polymer combinations may be incorporated in a hydroalcoholic solution to improve fragrance longevity. The polymer combination may include at least one plant-based hydrophobic polymer, a hydrophilic polymer, a third cosmetically acceptable sensory polymer, and a fragrance oil in hydroalcoholic solution having prolonged fragrance intensity. The tri-polymer combination may synergistically create a film mesh on the surface of the skin that locks in the fragrance ingredients. The combination may provide an unexpected film forming property with the fragrance oil in hydroalcoholic solution, thereby providing a thin film matrix and adhesive power for the fragrance ingredients to attach/remain on the skin.
