Title: Aqueous emulsion or colloidal soln. prodn. - by siphoning oily, fatty or waxy materials into an injector fed with water under pressure
Inventor: ZOELLNER WOLFGANG
IPC: A61K9/107
Filed: 1973-02-03
Abstract: Uniform, stable aq. emulsions of colloidal solns. of oily, fatty or waxy substances or mixts. of such substances are produced using an injector (i.e. water-aspirator pump). The oily, fatty or waxy substance(s), opt. in the molten state, are siphoned by the injector which in turn is fed with water under a pressure of 2-10 (pref. 2-4) atm. (gauge). The emulsification process is carried out continuously, and the emulsion can be recycled to the injector if a finer and/or more stable emulsion is required. Because the mixing chamber in the injector is relatively small, mixing times are short and undesired absorption of water by the disperse phase is minimized. The procedure can be used in the prodn. of emulsions or colloidal solns. of oily, fatty or waxy substances used as textile or leather finishing agents, in foodstuffs, or inpharmaceutical or cosmetic prepns.
