Abstract: The present invention relates to microcapsules comprising a hydrophobic core within a polymeric shell, wherein a) the polymeric shell is formed from shell components comprising: i) a polyisocyanate, wherein the polyisocyanate is selected from xylylene diisocyanate (XDI) and oligomers, adducts and derivatives thereof; ii) a polycaprolactone polyol comprising from 2 to 4 free hydroxyl groups; iii) a polyethyleneimine; iv) optionally, other shell components; and b) the hydrophobic core comprises an active material. The invention further relates to a slurry comprising the microcapsules, a home care formulation comprising the microcapsules, a personal care formulation comprising the microcapsules and a process for producing the microcapsules.

Abstract: The present invention provides microcapsules comprising a hydrophobic core within a polymeric shell, wherein: a) the polymeric shell is formed from shell components comprising: i) 50% to 85% by weight, on the basis of the total weight of shell components in the microcapsules, of a polyisocyanate, wherein the polyisocyanate is an oligomer of xylylene diisocyanate and wherein the polyisocyanate comprises at least 4 isocyanate groups; ii) an alkyl silicate; iii) a polyethyleneimine; and iv) optionally, other shell components; and b) the core comprises a fragrance material. The invention further provides home or personal care formulations comprising the microcapsules and a process of producing the microcapsules.
