Aculyn™ 38 Rheology Modifier
Aculyn™ 38 is an alkali-swellable
anionic acrylic polymer emulsion (ASE) that is lightly crosslinked
to impart a short pseudoplastic flow. It is a liquid, cold-processable
product that instantaneously thickens upon neutralization
providing ease of handling and increased manufacturing efficiency.
This thickener is offered at 28% solids and has been developed
for use as a rheology modifier and suspending agent for personal
care surfactant formulations. It is effective in a range of
personal care surfactants and is useful at pH 3-11, depending
on formulation. It is stable in the presence of sodium chloride
and two common conditioning agents, Polyquaternium-7 and Polyquaternium-10
as well as, polar solvents and zinc pyrithione. The polymer
has a well-established toxicological profile and is safe in
normal use.
