Abstract

Particles of a primary emulsion of an oil in a hydrophilic liquid containing a thickening agent are encapsulated by a process wherein the said primary emulsion is dispersed to form a secondary emulsion in an aqueous dispersion of at least two concervating colloids at least one of which is a gelable hydrophilic colloid and at least one is an isoelectric colloid (and optionally containing a thickening agent) at a temperature above the gel point of the gelable colloid and causing coacervation of the colloids on to the primary emulsion particles, e.g. by the addition of water or alteration of pH of the coacervating medium. Suitable thickening agents are materials which are substantially insoluble in the oil phase of the primary emulsion and are capable of imparting lipophilic character to the surface of the external phase of the primary emulsion; e.g. acacia, tragacanth, methyl- and carboxymethyl-cellulose, magnesium aluminium silicate, polyglycols, glycerine and syrups. As suitable colloids there are mentioned gelatine, agar-agar, albumen, alginates, casein, pectins, acacia, starch, fibrinogen, starch-, cellulose- and amylose-acetate phthalate. The primary emulsion may also contain a conventional emulsifying agent and either or both phases thereof may contain dissolved or suspended material which confers on the products of the invention uses as, for example, sustained release fertilizers, plant growth hormone preparations, bactericides, pesticides, ingredients for pre-mixed foods, vitamin preparations suitable for addition to dry cereal preparations, ingredients of cosmetic preparations, pharmaceutical preparations for oral, topical or injectable use (particularly of the sustained or delayed release type). Specific examples relate to capsules comprising urea, alizarin cyanide green, methyl neopolamine bromide and hexachlorophene. Details of the process used are given. Specification 751,600 is referred to.
