Described are personal care compositions comprising a polymer comprising: (a) one or more polymer comprising, as polymerized units, (i) 75% to 35% by weight, based on the weight of said polymer, one or more (meth)acrylate monomer selected from at least one of C1-C4 (meth)acrylate, (meth)acrylic acid, styrene, or substituted styrene, and (ii) 25% to 65% by weight, based on the weight of said polymer, one or more hydrophobic monomer, including hydrophobically substituted (meth)acrylate monomers, with alkyl chain length from C8 to C22 and, (iii) optionally crosslinker, and, (b) at least one personal care active. Optionally, the polymer further includes a stage 2 polymer comprising, as polymerized units, (i) 10-99% of one or more monomer which has a Tg of more than 80° C. after polymer formation, (ii) 1-10% of one or more (meth)acrylate monomer containing acid functional group, and (iii) optionally, a crosslinker.

A method of removing a tattoo from skin of a human subject. The method has the step of applying to a region of the skin having the tattoo a reducing composition that includes a reducing agent and a penetration enhancer in admixture. The penetration enhancer is present in an amount effective to effect penetration of at least at least a portion of the reducing agent through the skin to the location of the tattoo. The reducing agent is present in an amount effective to at least partially decolorize or break up a pigment of the tattoo. The reducing agent can be selected from the group consisting of sodium oxymethylene sulfoxylate and sodium hydroxymethane sulfinic acid.

The present invention is directed towards a cosmetic assembly, of use for the treatment of keratin fibres, comprising a cosmetic composition having a melting point of between 40° C. and 120° C., and comprising at least 15% by weight of meltable compound(s), relative to the total weight of the composition; and a device (1) comprising a mould (2), the mould (2) comprising at least one cavity (5), into which or each of which at least one of said fibres can be at least partially introduced, for the purposes of moulding said composition onto at least one part of said fibre(s) present in the cavity or cavities (5). The present invention is also directed towards a process for cosmetic treatment of one or more keratin fibres.

Methods for use in selectively conditioning and remineralizing teeth. An exemplary method comprises the steps of applying a conditioning composition to one or more of a person's teeth, and separately applying a remineralizing composition to the person's teeth. The conditioning composition includes a conditioning agent, and the remineralizing composition includes a remineralizing agent comprising calcium ions and/or fluoride ions. The conditioning composition may be applied prior to or after application of the remineralizing composition. In one embodiment, both the conditioning composition and the remineralizing composition include different remineralizing ions (e.g., one including calcium, one including fluoride).

Compositions are provided that provide release of insect repellant or fragrance over an extended period of time. The compositions comprise a hydrophilically-modified cross-linked silicone elastomer and an acrylic rheology modifier.

Disclosed are compositions comprising one or more latex polymers selected from acrylate latex, polyurethane latex polymers, and mixtures thereof, a dispersion of particles of at least one silicone latex polymer; and optionally, a solvent. Methods of using the compositions on keratinous substrates such as hair are also disclosed.

The present invention relates to a composition for dyeing keratin fibers, comprising a) one or more fatty substances, which are preferably liquid and non-silicone, b) one or more cellulose polymers and/or one or more carboxylic anionic, c) (2,5-diaminophenyl)ethanol, d) optionally, one or more couplers, e) optionally, one or more basifying agents, and f) one or more chemical oxidizing agents such as hydrogen peroxide, and the content of fatty substances in the composition representing in total at least 10%, in particular at least 15%, more particularly at least 20% and preferably at least 25% by weight relative to the total weight of the composition resulting from the mixing of (A′)+(B′)+(C′).
