Abstract: 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.

Abstract: Microcapsules of a fluorescent whitening agent in a transparent or translucent polymer formed from a mixture of hydrophobic and ionic monomers that are capable of forming a homopolymer of glass transition temperature in excess of 50° C., wherein the fluorescent whitening agent is not bonded to the surface of a particulate substrate, provide attractive aesthetic effects when incorporated into personal care or cosmetic compositions.

Abstract: 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° 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° 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 colourant.

Abstract: 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.

Abstract: Cosmetic or personal care compositions which comprise at least one fluorescent colorant other than white and at least one non-fluorescent colorant, are useful in preparing colored cosmetic or personal care preparations providing an enhanced skin appearance.

Abstract: Microparticles containing an effective amount of at least one fluorescent whitening agent, wherein said fluorescent whitening agent is entrapped in a transparent or translucent matrix polymer 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° C., wherein secondary particles are distributed throughout the matrix, which secondary particles comprise a hydrophobic polymer that has been formed from an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer having a glass transition temperature in excess of 50° C. and optionally other monomers, which hydrophobic polymer is different from that of the matrix polymer, exhibit improved shatter resistance.

Abstract: 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.
