Aculyn™ 44 Rheology Modifier
Aculyn™ 44 is a nonionic thickener
based upon Hydrophobically-modified Ethoxylated Urethane (HEUR)
chemistry designed for personal care applications. As with
other Aculyn™ rheology modifiers, the polymer is a liquid
product for easier handling and manufacturing efficiency.
Aculyn™ 44 is offered at 35% solids, is stable from
pH 2 to 12 and compatible with peroxide and other oxidizing
agents. The polymer has a well-established toxicological profile
and is safe in normal use.
