Title:
METHOD OF MAKING PERFUME-CONTAINING PARTICLES
Document Type and Number:
WIPO Patent Application WO/2023/142099
Kind Code:
A1
Abstract:
A method of making perfume-containing particles is provided. Each of such particles contains a perfume ingredient; a first carrier, and a second carrier, wherein the first carrier comprises water-soluble and hot-meltable material, and the second carrier comprises water-soluble or water-dispersible particle, wherein from 80 wt % to 100 wt % of the second carrier are characterized by a particle size ranging from 5 microns to 150 microns, wherein each of said perfume-containing particles has a mass of from 0.1 mg to 5 g and a maximum dimension of from 3 mm to 10 mm, said method comprising steps of: a) providing an intermediate particle characterized by a maximum dimension ranging from 0.5 mm to 10 mm, wherein the intermediate particle comprises at least the second carrier, and a binder, b) mixing the intermediate particle, the perfume ingredient, the first carrier in a molten state, and optionally one or more other ingredients, to form a slurry, and c) forming the perfume-containing particles from the slurry.
