A crosslinked, nonionic, amphiphilic polymer is prepared by polymerizing a monomer mixture comprising an amphiphilic additive. The obtained polymer is useful for forming a clearer yield stress fluid in combination with a surfactant. The yield stress fluid is capable of suspending insoluble materials in the presence of electrolytes, perfumes, fragrances and/or organic acid preservatives.

A memory-shape skin-care composition, in the form of an oil-in-water emulsion, including a UV filter system, including avobenzone, octocrylene, and homosalate. The composition additionally includes a thickening emulsifier including a co-polymer including a stearate derivative and a polyethylene glycol derivative, a non-thickening emulsifier including a polyglyceryl stearate co-polymer, and a memory-shape material including a polyethylene glycol/hexamethylene diisocyanate co-polymer.

The present invention relates to a method for making a direct emulsion of a copolymer in water, characterized in that it comprises the polymerization of at least, expressed as a percentage by weight of each of the monomers based upon the total weight of the monomers: a) 10 to 80% by weight of methacrylic acid and, optionally, of acrylic acid; b) 15 to 80% by weight of at least one non-ionic vinyl monomer; c) 0.05 to 9.5% by weight of 2-acrylamido-2-methylpropane sulfonic acid or a salt thereof; d) 0.5 to 30% by weight of at least one monomer containing at least one hydrophobic group; and e) 0.01 to 5% by weight of at least one crosslinking monomer; said polymerization being carried out in the presence of at least one surfactant.

It also relates to the corresponding new copolymer emulsion in water, a method for thickening an aqueous composition comprising such an emulsion of copolymer and to an aqueous composition comprising such a copolymer emulsion.

A cosmetic ink composition comprises a particulate material, a polymeric dispersant having a weight average molecular weight of less than about 20,000 daltons, and a polymeric rheology modifier. The particulate material can have a Particle Size Distribution D50 of about 100 nm to about 2,000 nm. The cosmetic ink composition can undergo controlled syneresis, forming a weak colloidal gel phase and a particle-lean, low viscosity phase, which can be printed without interventions such as agitation, mixing, or re-circulation to homogenize the composition.

The invention relates to stable dispersions, containing (a) 50 to 80% by weight of perfume oils, (b) 10 to 30% by weight of encapsulated fragrances, (c) 0.01 to 0.1% by weight of non-ionic polymers of the type of hydrophobically modified hydroxylalkyl guar compounds, with the proviso that the constituents together with water and optionally other typical auxiliary agents and additives add up to 100% by weight.

The present invention relates to a composition for dyeing keratin fibers, comprising a) at least one oxidation dye precursor, b) at least one anionic associative polymer i), c) at least one anionic non associative polymer ii), and d) at least one anionic surfactant. The composition optionally contains alkaline agent.

The invention relates to a novel composition and method of manufacturing personal lubricant, commonly known as lube, to combine the most desirable features of disparate existing lube compositions to create a long lasting, oil-based, water soluble, non-toxic, anti-microbial, anti-yeast, non-staining, personal lubricant that can be organically sourced and will not damage commonly used prophylactics.

The invention relates to a cosmetic composition comprising: (a) at least 2% by weight, relative to the total weight of the composition, of one or more compounds chosen from urea and/or urea derivatives, (b) one or more polymeric thickeners chosen from nonionic, cationic, amphoteric polymeric associative thickeners or anionic polymeric associative thickeners comprising one or more acrylic and/or methacrylic units. The invention also relates to the use of this composition for straightening keratin fibres. Finally the invention relates to a process for straightening keratin fibres.

The present invention relates to a device (1) for dyeing keratin fibres, comprising at least two compartments (2) and (3), the first compartment (2) comprising a first composition (A) comprising oxidation dyes and the second compartment (3) comprising a second composition (B) comprising chemical oxidizing agents. Said device allows easy mixing of the compositions contained in said compartments at the time of use.

The present invention relates to a cosmetic composition comprising: a) at least one anionic surfactant chosen from polyoxy alkylenated alkyl(amido)ether carboxy lic acids and salts thereof: b) at least one amphoteric or zwitterionic surfactant: c) at least one associative polymer: and d) at least 2% by weight, relative to the total weight of the composition, of one or more polyols.
