Aristoflex® HMB is a hydrophobically modified synthetic polymer used as gelling agent for aqueous systems and as texturizer or thickener for oil-in-water emulsions. The polymer is pre-neutralized, easy to use and provides formulations with excellent yield value, corresponding to superior stability even in the absence of additional emulsifier. Due to the hydrophobic modification, even low concentrations of this product stabilize high amounts of oil.
