Abstract: Rupturable microcapsules made up of very small droplets or globules of perfume oil encapsulated with an inert polymeric wall are stabilized by providing ethyl cellulose in the perfume oil. This measure prevents escape of higher volatility components of the oil, which would otherwise occur during the preparation process. The stabilized microcapsules may be prepared by a liquid bath encapsulation method wherein ethyl cellulose is first dissolved in the starting oil, and the resulting solution is emulsified by mixing with a gelatin solution in water. The emulsion is then combined with a coacervant and cross-linking agent. Upon cooling the system, a gelatin-based wall coating is deposited around the emulsified particles. Fragrance characteristics of the starting perfume are preserved by this means.
