Abstract:
A method for forming a topical antimicrobial skin sanitizing and conditioning composition comprising:1) forming a surfactant phase mixture, based upon a percentage by weight of the total composition, by first combining 83.5 wt. % deionized water, 0.16 wt. % EDTA Sodium Salt and 0.35 wt. % of an acrylic polymer within a vessel containing mixing means and recirculating means;2) operating said mixing means in the reverse mode while operating the recirculation means at 100-150 gpm at a pressure of 60-110 psi, whereby the acrylic polymer is completely solubilized in said surfactant phase mixture;3)homogenizing said surfactant phase mixture for 30-40 minutes under conditions sufficiently rigorous to yield a grain free, homogeneously blended mixture;4) further adding, in the order and amounts stated, 3.0 wt. % Octyl Phenyoxypolyethoxy non-ionic surfactant, 1.0 wt. % Propylene Glycol (USP), 2.0 wt. % Nonylphenol polyethylene glycol ether non-ionic surfactant; 0.1 wt. % Sodium O-Phenylphenatetetrahydrate, 0.13 wt. % 2,4,4'-trichloro-2'-hydroxydiphenyl ether, 1.0 wt. % Triethanolamine 85% N.F., 0.16 wt. % Chlorhexidine Digluconate 20%, and 0.1 wt. % Alpha Tocopherol to said surfactant phase mixture;5)further mixing the above ingredients to form a homogeneous blend while heating to within a temperature range of 70.degree. C.-85.degree. C.;6)maintaining the surfactant phase mixture within said temperature range while mixing and pump recirculation are continued;7)in a separate vessel, forming a wax phase mixture by combining 3.0 wt. % Stearic Acid, 1.5 wt. % Cetyl Alcohol N.F., 0.75 wt. % Ethylene Glycol Monostearate, 2.0 wt. % Dimethicone, and 0.25 wt. % USP White Wax;8) heating said wax phase mixture to within a temperature range of 70.degree. C.-85.degree. C. and maintaining the temperature of said wax phase mixture within said temperature range while mixing;9) adding the wax phase mixture to said surfactant phase mixture to form a final phase mixture under conditions of homogenization, recirculation and pressure for 45-60 minutes;10) lowering the temperature of said final phase mixture to less than 50.degree. C.; and11) adding 1.0 wt. % of a mixture of Methyl,Ethyl,Propyl and Butyl Parabenzene in a Phenoxy-Ethanol solvent and continuing homogenization for an additional 20-30 minutes with total recirculation at a rate of about 100-150 gpm at a pressure of 60-110 psi.
