A process for preparing spherical polymeric particles of polymers containing at least two fillers, dispersed in the polymer matrix wherein up to 50% of the weight of the particles is composed by fillers. The process comprises a melt-blending of a polymeric matrix containing the at least two fillers with a continuous phase that is not miscible with the polymeric matrix and an agent to form an emulsion. This emulsion is then extruded, cooled and a solvent of the continuous phase is added to recover the spherical particles. The fillers can provide different properties to the spherical particles which can be used, for example, for cosmetic applications, specifically for preventing and/or reducing the signs of skin ageing.

Provided are an emulsion composition which can be produced more easily than a conventional method and has excellent emulsion stability, and a method for producing the same. The emulsion composition contains a liquid conjugated diene rubber, a diluent having a vapor pressure at 20° C. of 10 Pa or less, a surfactant, and water.

The present invention relates to an elastomeric composition comprising a silicone rubber, glycerol, at least one crosslinking agent, and optionally one or more excipients, wherein said glycerol is present as discrete droplets in the silicone rubber, obtainable through the application of high shear forces.

This invention concerns a novel method to produce thermosets such as epoxies and polyurethanes comprising nano-cellulose. The method comprises contacting primarily water-bourne dispersed nano-cellulose with liquid thermoset precursors, specifically epoxy or amine in the case of epoxies, or glycols or similar in the case of polyurethanes. Nano-cellulose transfers to the organic phase, and water is removed at temperatures below 100° C. Thereafter the organic phase comprising nano-cellulose can be mixed with the reactive counterpart to yield nano-composites with improved properties. The products can be used for composite articles, coatings, adhesives, sealants, and other end-uses. Preferred embodiments are described in detail.
