Polymeric particles comprising a polymeric matrix that has been formed from a blend of monomers comprising a first monomer which is an ethylenically unsaturated ionic monomer and a second monomer which is an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50&#xb0; C., wherein secondary particles are distributed throughout the matrix, in which the secondary particles comprise a hydrophobic polymer that has been formed from an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50&#xb0; C. and optionally other monomers, which hydrophobic polymer is different from the polymeric matrix. Also claimed is a process for preparing particles. The particles have improved shatter resistance. Preferably the polymeric particles comprise an active ingredient, especially a colorant. Such particles combine improved shatter resistance with the ability to retain the active ingredient. The particles of the invention can be used in a variety of industrial applications, for instance in the manufacture of inks, paper and cosmetics.

Polymeric particles

Disclosed are oligo- or polysiloxanes, which are characterized by containing at least 3, for example 4-3000, Si atoms in the main chain, and wherein at least one thereof is contained in a moiety of the formula (I) whose variables and attachments are described within.  The disclosed are oligo- or polysiloxane compounds are effective as antimicrobials.

Polysiloxane antimicrobials

Compositions containing polyorganosiloxanes having at least one quaternary group comprising at least one nitrogen atom, and at least one further polar radical, and their use in cosmetic, in particular for the conditioning of hair.

Polysiloxane compositions

Anti-microbial compositions comprising certain imidazolium ionic liquids and non-ionic or anionic surfactants and methods of using said compositions in the preservation of personal care and cosmetic applications are provided.

Anti-microbial compositions

The present invention provides an emulsion comprising an organic discontinuous phase which is distributed throughout a continuous aqueous phase, wherein the organic phase comprises,  The present invention also relates to personal care compositions comprising emulsions containing encapsulated fragrances for improved fragrance delivery. The present invention also relates a method of use that comprises application of an effective amount of a liquid or solid personal care composition comprising an emulsion that contains a fragrance encapsulated in microparticles to at least one part of the body.

Emulsions containing encapsulated fragrances and personal care compositions comprising said emulsions

Carboxylic acid ester derivatives of zosteric acid are effective in preventing biofouling and are readily formulated into coatings or films. Coating or film compositions of the esters, and methods for their application, are provided which reduce the dissolution of the esters into water or loss to the environment. The Zosteric acid esters of the invention appear to function by preventing adhesion of an organism to a surface rather than by acute toxic activity rendering said compositions more environmentally acceptable.
