Abstract
A composition comprising a biopolymer matrix, said biopolymer matrix comprising from about 0.1% to about 40% of an essential oil, about 30% to about 95% of a biopolymer, and about 0% to about 50% of a carrier fluid wherein a limited amount of said essential oil can be released from said matrix composition when exposed to a liquid solution; and wherein an additional limited amount of said essential oil can be re-released repetitiously thereafter upon re-use with an additional exposure of a liquid solution.
Claims14
A composition comprising a biopolymer matrix, said biopolymer matrix comprising from about 0.1% to about 40% of an essential oil based on the total weight of the composition, about 30% to about 95% of a biopolymer based on the total weight of the composition, and about 5% to about 50% of a carrier fluid based on the total weight of the composition;
- wherein a portion of the about 0.1% to about 40% of the essential oil can be released from said matrix composition when exposed to a liquid solution;
- and wherein an additional portion of the about 0.1% to about 40% of the essential oil can be re-released repetitiously thereafter upon removal of liquid followed by additional exposure of a liquid solution, wherein the biopolymer matrix is in the form of particles having a particle size of from about 1 micrometer to about 10,000 micrometers, wherein the particles are formed by downsizing an extruded strand of the biopolymer matrix.
