Related methods of making and using such compositions.
Claims17
A composition comprising:
- a population of delivery particles,
- wherein the delivery particles comprise a core and a shell surrounding the core,
- wherein the shell comprises a polymeric material,
- wherein the polymeric material comprises a reaction product of a biopolymer and a cross-linking agent,
- wherein the biopolymer comprises secondary or primary amine groups,
- wherein the core comprises a fragrance material, wherein the fragrance material comprises:
- (a) at least about 30%, by weight of the fragrance material, of ester-containing perfume raw materials (“PRMs”), and
- (b) at least about 0.5wt %, by weight of the fragrance material, aldehyde-containing PRMs.
