Procedure | |
Phase A—Add glycerin to deionized water. Phase B—add ingredients 3-6 in a separate vessel. Disperse Pemulen TR-2 Polymer into oil phase. Add phase B to phase A. Mix for 20-30 minutes to allow the polymer to swell. Neutralize batch with sodium hydroxide (5%). Mix vigorously until uniform. Add coco-glucoside. Mix slowly to avoid air entrapment. Add preservative (phase E). Mix until uniform. Dilute with deionized water. Mix until uniform. | |
Properties | |
Appearance—thin white lotion; pH—5.8-6.2; Viscosity (mPa·s) (Brookfield RVT @ 20 rpm, 25°C, #2 spindle, measured after 24 hours)—400-700; Stability—passed 3 months @ 45°C and RT, Passed 5 cycles freeze/thaw. | |
More Information | |
This formula has not been tested on any nonwoven substrate, but is a suggested starting point formulation to help meet difficult viscosity and emulsion stability criteria. Preservation and stability may be dependant on the non-woven substrate that is used for application. | |
