Abstract
The present invention relates to gelled emulsion particles obtained when predetermined volumes, especially drops, of an emulsion with an aqueous external phase, containing an appropriate reagent in solution in the said aqueous phase, are added to a gelling solution and left therein for a period of time which depends on the degree of gelling desired for the said particles. It further relates to compositions-especially solutions, gels or emulsions with an aqueous external phase-in which the said particles are present.
Claims14
A composition comprising (a) particles of gelled emulsion, said particles produced by adding discrete volumes of at least one emulsion to a gelling solution, said emulsion containing at least one active ingredient and having an aqueous external phase containing in solution therein a soluble reagent which produces gelling at least at the peripheries of said discrete volumes upon reaction with said gelling solution, and (b) a medium containing a sufficient amount of base to decrease the rigidity of said particles of gelled emulsion,
- said particles being contained in said medium.
