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.

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.
