Disclosed are stable microcapsule compositions each containing a microcapsule dispersed in an aqueous phase and a stabilizing agent. The microcapsule compositions are stable for at least 4 weeks when storing at 45° C., and the microcapsule composition is considered stable when (i) the composition has a viscosity of 3000 cP or less and (ii) 20% or less water by volume of the composition is separated from the composition. Also disclosed are consumer products having such a stable microcapsule composition.

A microporous animal chew comprising a rawhide sheet having a thickness in the range of 0.1 millimeters to 3.0 millimeters and a plurality of micropores extending through said rawhide sheet at least partially filled with chitosan. The rawhide sheet provides a digestible yet chewable and durable animal chew.

The present invention relates to an aqueous composition comprising at least one dispersion of polymer particles in a non-aqueous medium, at least one cationic polymer and at least one anionic polymer. The present invention also relates to a cosmetic treatment process, notably a process for styling keratin fibres, in particular human keratin fibres such as the hair, using this composition. Finally, the present invention relates to the use of this composition for the cosmetic treatment of keratin fibres, in particular of human keratin fibres such as the hair, and in particular for styling the hair, i.e. for shaping and/or fixing the head of hair.

Injectable prolonged-action compositions for use in the treatment of nail diseases, including potentially promoting the growth of the nail, or for use promoting the growth of the nail. The compositions are administered subcutaneously, and optionally as an implant. The compositions may be in solid or non-solid form and include one or more solid biodegradable sustained-release polymers, and optionally one or more active substances.

The present invention relates to the use of a methacrylate or acrylate modified polysaccharide; or a single-chain polysaccharide methacrylate or acrylate-based nanoparticle, having a surface tension measured by Du Noüy Ring method equal to or lower than 63 mN/m, as oil-in-water emulsion stabilizer; and an oil-in-water emulsion stabilizer composition, and an oil-in-water emulsion containing them. It also relates to processes for their preparation, and their uses.

The present invention is directed to a new cross-linked chitosan, preparations, compositions and uses thereof. In particular, the invention relates to nanoparticles and compositions thereof useful as active agents and delivery systems for at least one bioactive agent.

The present invention relates to a composition for surface modification. The composition for surface modification according to the present invention contains a particular carbodiimide-based compound, thus forms a covalent bond without damaging skin, hair, or fabric, and semipermanently provides desired skin or hair surface modification effects or fabric care effects.

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

The present invention relates to a solid phase cosmetic composition comprising a freeze-dried component of a composition comprising a functional component and a basic amino acid. A solid phase component according to the present invention has excellent re-dissolvability, and exhibits insignificant changes in the hardness and pH of the composition for dissolving the solid component even after re-dissolution, and thus a cosmetic having excellent stability can be provided.

An article of manufacture is described comprising the combination of an adjunct material and a delivery particle. The delivery particle comprising a benefit agent core material and a shell encapsulating the core material is described, along with a process for forming such a delivery particle and articles of manufacture. The shell is the reaction product of: i) an isocyanate or acid chloride or acrylate with ii) an amine-containing natural material having free amino moieties, and iii) an α, β-unsaturated compound, the α, β-unsaturated compound forming C—N covalent bonds with the amine moieties of the natural material. The delivery particle of the invention has improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.
