| titleOfInvention | Laundry treatment compositions comprising perfume and silica microparticles |
| abstract | 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) 3 -Si-(CH 2 ) n -Ar-(CH 2 ) m -Si-(OR') 3 (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' is independently a C 1 to C 5 alkyl 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' is independently a C 1 to C 5 alkyl group and R'' 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. |
