Aculyn™ 28 Rheology Modifier
Aculyn™ 28 is an anionic associative
rheology modifier developed specifically for hair and skin
care applications. This thickener is a hydrophobically-modified
alkali soluble polymer emulsion (HASE) with unusually high
aqueous thickening and stabilizing efficiency. The polymer
is a liquid, cold-processable product that instantaneously
thickens upon neutralization, providing ease of handling and
increased manufacturing efficiency.
Aculyn™ 28 is designed for clear formulations, stable
from pH 5.5 to 10 and compatible with nonionic, anionic, Zwitterionic
and some cationic ingredients, as well as peroxide and electrolytes.
The lower pH neutralization makes it ideal for skin care applications.
