The present invention relates to a composition comprising particles of at least one polymer that is surface-stabilized with a stabilizer, the polymer of the particles being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer; the stabilizer being an isobornyl (meth)acrylate polymer chosen from isobornyl (meth)acrylate homopolymer and statistical copolymers of isobornyl (meth)acrylate and of C.sub.1-C.sub.4 alkyl (meth)acrylate present in an isobornyl (meth)acrylate/C.sub.1-C.sub.4 alkyl (meth)acrylate weight ratio of greater than 4, at least one hydrocarbon-based oil and at least one amorphous hydrocarbon-based block copolymer obtained by polymerization of at least one monomer of unsaturated hydrocarbon type comprising 2 to 5 carbon atoms and containing one or two ethylenic unsaturations. The invention also relates to a process for making up and/or caring for keratin materials, in which said composition is applied.

Disclosed is a personal care composition comprising: a) particle comprising chitosan salt at the outer surface of the particle; and b) silicone component selected from dimethicone, aminosilicone or a mixture thereof, wherein the silicone component has a viscosity of at least 5,000 cSt at 25 C.

Disclosed is a preparation for the interdental delivery of oral care agent. The preparation comprising one or more oral care agents contained in particles comprising an orally acceptable release matrix, wherein the particles are resiliently deformable and capable of being compressed so as to fit in an interdental space. The particles can thus be provided in a size slightly larger than that of an interdental space. By compression they can be inserted, particularly jetted, into interdental spaces, and their tendency to thereupon expand again provides a force retaining them in the space where they were applied, without being prone to washing away by saliva.

Methods of making personal care compositions including microcapsules and methods of enhancing the efficacy of the microcapsules in said personal care compositions.

Provided herein are compositions and methods comprising phosphonates, N-halamines or combination thereof for dental care. Specifically, for removing tartar (calculus), including mature tartar.

A composition, especially a cosmetic composition, in particular for making up and/or caring for keratin materials, including at least one aqueous phase gelled with at least one hydrophilic gelling agent; and at least one oily phase gelled with at least one lipophilic gelling agent chosen from organopolysiloxane elastomers; said phases forming therein a macroscopically homogeneous mixture. The composition also includes a dispersion of solid aggregates, said aggregates being formed from 10% to 80% by weight of wax(es), relative to their total weight. Also disclosed is a process for preparing such a composition.

Core-shell particles have a hydrophobic core and a shell formed of o containing hyperbranched polymers (HP). The HP can be covalently bound to the one or more materials that form the core or coated thereon. The HP coating can be modified to adjust the properties of the particles. For example, unmodified HP coatings resist non-specific protein absorption. Alternatively, the hydroxyl groups on the HP coating can be chemically modified to form functional groups that react with functional groups on tissue to adhere the particles to the tissue, cells, or extracellular materials, such as proteins. Such functional groups include, but not limited to, aldehydes, amines, and O-substituted oximes. Topical formulation for application to the skin contain these HP coated nanoparticles. In some embodiments, the particles include cosmetic, therapeutic, diagnostic, nutraceutical, and/or prophylactic agents, such as those used as sunblock compositions.

Alkali-swellable rheology modifier comprising a core-shell polymer comprising a core polymer and a shell comprising at least one shell copolymer layer at least partially cross-linked and containing a mole percent of crosslinking agent greater than the mole percent of crosslinking agent in the core polymer, provided if the mole percent of crosslinking agent in the core polymer is zero, then either the core polymer is greater than 60 wt % of the core-shell polymer; the core polymer comprises at least one associative monomer; at least one shell copolymer layer copolymer comprises at least one associative monomer; and/or the at least one shell copolymer layer that is at least partially cross-linked comprises greater than 3 mole% crosslinking agent. Aqueous compositions comprising the alkali-swellable rheology modifier include personal care formulations, healthcare formulations, agricultural formulations, paint formulations, coating formulations, laundry and fabric care formulations, household cleaning formulations, and industrial and institutional cleaning formulations.

The present invention relates to an in-vivo bulking agent which can be used as a medicinal agent for prevention or treatment of at least one disease selected from the group consisting of urinary incontinence, fecal incontinence, and gastroesophageal reflux or as a filler for use in a plastic surgery procedure, and to a preparation method therefor. The in-vivo bulking agent can exhibit a bulking effect when injected into the body and particularly, is highly biocompatible because a first composition in which silicone particles are coated with a zwitterionic polymer having a surfactant property is introduced into a second composition, whereby the bulking agent can inhibit inflammatory reactions in vivo.

The present invention relates to a new process for the preparation of core-shell microcapsules. Microcapsules are also an object of the invention. Consumer products comprising said microcapsules, in particular perfumed consumer products or flavoured consumer products are also part of the invention.
