ABSTRACT:
The present invention relates to particle stabilizing compositions suitable for use in fabric care products, home care products, diapers, incontinence articles, feminine care products, pharmaceuticals, oral care products, antiperspirants, deodorants, personal cleansing products, skin care products and hair care products comprising: a) an emulsion comprising from about 1% to about 99% by weight of the emulsion of an internal phase and from about 1% to about 99% by weight of the emulsion of an external phase; b) a charged species that is present in the emulsion; and c) charged insoluble solid particles which are dispersed in the emulsion wherein the charged species possesses a charge which is opposed to that of the charged insoluble solid particles and wherein essentially all of the charged species and charged insoluble solid particles accumulate at the interface of the emulsion and wherein Brownian motion is not exhibited by the charged insoluble solid particles.
