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 package comprising a container containing gelled particles and a medium selected from the group consisting of solutions, emulsions having an aqueous external phase, and gels obtained with a water-dispersible gelling agent selected from the group consisting of carbomers, acrylic polymers, carboxymethyl cellulose, carboxyethyl cellulose, carboxypropyl cellulose and xanthene gums, said container being equipped with dispensing means such that passage therethrough causes said gelled particles, by mechanical action, to blend with said medium to produce a homogeneous blend, said gelled particles produced by adding to a gelling solution discrete volumes of an emulsion containing an 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.
