A core shell microcapsule having a liquid core and an outer shell, in which the liquid core comprises solvent and a piroctone compound and the shell comprises polyurea formed from monomeric units of aliphatic isocyanates and amines.

Microcapsule and hair care composition

A personal care composition comprising a surfactant-insoluble piroctone complex and a surfactant.

Personal care compositions comprising a metal piroctone complex

A core shell microcapsule having a liquid core and an outer shell, in which the liquid core comprises solvent and a piroctone compound and the shell comprises polyurea comprising amino sulphonic acid.

A laundry treatment composition comprising: i) at least 5 wt % amphiphilic material, preferably selected from the group consisting of detersive surfactants and quaternary ammonium compounds, ii) from 0.1 to 5 wt % perfume, iii) 0.2 to 6 wt % of porous microparticles comprising sol-gel derived material, the sol-gel derived material including a plurality of alkylsiloxy substituents and wherein the sol-gel derived material is obtained from: (a) at least one first alkoxysilane precursor having the formula: (R'O)&#x2014;Si&#x2014;(CH)&#x2014;Ar&#x2014;(CH)&#x2014;Si&#x2014;(OR&#x2032;)(1) where n and m are individually an integer from 1 to 8, Ar is a single-, fused-, or poly-aromatic ring, and each R&#x2032; is independently a Cto Calkyl group and (b) optionally, at least one second precursor having the formula: (formula) (2) where x is 1, 2, 3 or 4; y is 0, 1, 2, 3; z is 0, 1; the total of x+y+z is 4; each R is independently an organic functional group; each an R&#x2032; is independently a Cto Calkyl group and R&#x2033; is an organic bridging group, where the sol-gel derived material is swellable to at least 2.5 times its dry mass, when placed in excess acetone, whereby the weight amount of iii) exceeds the weight amount of ii) in the composition. Also, a method of prolongation of perfume delivery from a liquid laundry treatment composition comprising perfume, the method comprising the steps of: (i) adding sol-gel derived silica microparticles as described above to the liquid composition; C30068 EP (C) CPL (ii) optionally, diluting the liquid and applying the liquid or the diluted liquid to a surface to be treated to deposit the microparticles onto the surface; (iii) rinsing away the liquid or diluted liquid to leave perfume loaded microparticles on the surface to be treated; and (iv) releasing perfume from the microparticles over period of about 24 hours. 

Laundry treatment compositions comprising perfume and silica microparticles

The invention provides a use of a particle to absorb and retain odiferous compounds, wherein the particle comprises: &#x2014;(a) a solid core comprising a first hydrophobic polymer, and (b) a shell comprising a second hydrophobic polymer wherein the Tg of the first hydrophobic polymer is lower than the Tg of the second hydrophobic polymer; wherein the particles have a mean particle size of less than 1 micron, preferably from 0.1 to 0.3 microns, and wherein the odiferous compound is a malodor compound.

Use of a benefit delivery particle for malodour benefit

The invention provides a benefit agent delivery particle having an average diameter of less than 50 micron comprising; at least one shell formed by a step-growth polymerization reaction, preferably involving an isocyanate monomer, more preferably a urethane and/or a urea. interior said shell, at least one region formed by chain-growth polymerization reaction (preferably a free-radical polymerization) which does not involve an isocyanate, c) optionally, a benefit agent interior to said shell, and/or a deposition aid exterior to said shell. The invention further provides a process for the preparation of such particles wherein the shell is formed prior to the chain-growth polymerization of the at least one region interior of the shell, preferably be forming the shell at a temperature at which the chain-growth reaction is inhibited. The invention further provides fully formulated products, preferably liquids and gels, which contain said benefit agent delivery particles and a method of treating substrates using said products.

Benefit delivery particle, process for preparing said particle, compositions comprising said particles and a method for treating substrates
