Procedure
Prepare a 1.5% solution of SoftCAT SL-30 polymer by sprinkling into agitating, room temperature water. Allow to disperse completely before beginning to heat slowly, with mixing, to 60-65°C. Let cool to room temperature before use. Solution should be crystal clear. Prepare a 1% solution of Polyox WSR N-750 by sprinkling into room temperature rapidly agitating water. Allow polymer to dissolve completely. Prepare a 5% solution of Methocel 4-202 by sprinkling into room temperature rapidly agitating water. Allow polymer to disperse completely. Adjust pH to at least 8.5 using NaOH (10% aq.) to fully hydrate the polymer. Combine sodium laureth sulfate, disodium amphodiacetate and EGDS. Mix with heating to 70-75°C until all the EGDS is melted and uniform. Continue stirring at thsi temperature for 45 minutes then add citric acid solution. Begin to cool slowly to 35°C. Add silicone emulsion with mixing and continue stirring for another 90 minutes. Once complete, slowly add the polymer solutions while mixing. Once all the solutions are added continue mixing for 60 minutes. Cool to room temperature; add preservative, fragrance and color.
