Abstract
A biodegradable core-shell microcapsule composition with controlled release of an active material is provided, wherein the shell of the microcapsule is composed of a biopolymer.
Claims13
A biodegradable core-shell microcapsule composition with controlled release of an active material,
- (i) the core of the biodegradable core-shell microcapsule comprising at least one active material, and
- (ii) the shell of the biodegradable core-shell microcapsule comprising at least one biopolymer cross-linked with one or more cross-linking agents,
- wherein said microcapsule retains the at least one active material for at least four weeks at elevated temperature in a consumer product base and releases the at least one active material in response to at least one triggering condition.
A biodegradable core-shell microcapsule composition with controlled release of an active material,
- (i) the core of the biodegradable core-shell microcapsule comprising at least one active material, and
- (ii) the shell of the biodegradable core-shell microcapsule comprising at least one denatured and cross-linked plant storage protein,
- wherein said shell retains the at least one active material for at least four weeks at elevated temperature in a consumer product base and releases the at least one active material in response to at least one triggering condition.
A method of producing a biodegradable core-shell microcapsule comprising
- (a) denaturing at least one plant storage protein,
- (b) emulsifying the at least one denatured plant storage protein with at least one active material, and
- (c) cross-linking the at least one denatured plant storage protein with one or more cross-linking agents, thereby producing a biodegradable core-shell microcapsule.
