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: 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: The present invention relates to personal care or cosmetic compositions that contain a shatter-resistant blend of microencapsulated colorants that can produce a natural, textured tone effect. A method for cosmetic treatment comprises application of such personal care or cosmetic compositions onto at least a part of the body.

Abstract: The present invention relates to personal care or cosmetic compositions that contain a blend of at least 2 microencapsulated colorants that produces a natural, textured tone effect. A method for cosmetic treatment comprises application of such personal care or cosmetic compositions onto at least a part of the body.
