Suspending Agent SF-1 Acylates Copolymer Personal Care Homecare
EP1
INCI Name & CAS No.
Acylates Copolymer & 25035-69-2
Description
EP1 is an excellent rheology modifier, alkali-swellable anionic acrylic polymer emulsion, lightly crosslinked. It’s easy to handle due to water-soluble and low-viscosity.

Formula Guidelines
The minimum recommended use level of EP1 polymer in surfactant-based products is 5.0% as supplied. The polymer use level depends on the amount of surfactant and assumes use of salt for additional thickening. For clear formulations containing no salt and low surfactant actives, typical polymer use levels are 8-10% as supplied.
In most situations,EP1 polymer can be added to the free water of a formulation with gentle mixing at the start of the batching process. At this point, the pH will be about 3, resulting in very low viscosity. Upon addition of a base, the polymer will be neutralized, resulting in immediate increase in suspending properties and viscosity.
