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.

Glycerol
Hair dye
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.
