Aculyn™ 46 Rheology Modifier
Aculyn™ 46 is a nonionic Hydrophobically-modified
Ethoxylated Urethane (HEUR) thickener designed for personal
care applications. As with other Aculyn™ rheology modifiers,
the polymer is a liquid product for easier handling and manufacturing
efficiency. Aculyn™ 46 is offered at 18 to 20% 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.
