Abstract
Dispersions of an encapsulated material by a polymeric membrane in a medium are disclosed. Such dispersions are useful in topical compositions including cosmetics and sunscreens.
Claims16
A dispersion comprising an encapsulated material dispersed in a medium that is substantially immiscible with the encapsulated material, wherein the encapsulated material is encapsulated by a polymeric membrane, wherein the dispersion does not include a surfactant for dispersing the encapsulated material in the medium, wherein either the encapsulated material is an aqueous composition or the medium is an aqueous medium and glycerin is included in the aqueous composition or the aqueous medium in an amount greater than 10 wt % of the dispersion and wherein the average size of the encapsulated material dispersed in the medium is less than 500 microns.
A dispersion comprising an encapsulated polyorganosiloxane dispersed in an aqueous medium that is substantially immiscible with the encapsulated polyorganosiloxane, wherein the encapsulated polyorganosiloxane is encapsulated by a polymeric membrane, wherein the aqueous medium includes glycerin and wherein the average size of the encapsulated polyorganosiloxane dispersed in the aqueous medium is between 5 microns to 300 microns.
A dispersion comprising an encapsulated polyorganosiloxane dispersed in an aqueous medium that is substantially immiscible with the encapsulated polyorganosiloxane, wherein the encapsulated polyorganosiloxane is encapsulated by a polymeric membrane, wherein the aqueous medium includes glycerin in an amount greater than 10 wt % of the dispersion and wherein the average size of the encapsulated polyorganosiloxane dispersed in the aqueous medium is less than 500 microns.
