Acrylic Acid/VP Crosspolymer is a thickener supplied by Ashland under the tradename UltraThix™ P-100 polymer. It is a cross-linked copolymer of vinyl pyrrolidone (VP) and acrylic acid.
It is claimed by Ashland to be a multi-benefit, patented rheology modifier that delivers an array of benefits, such as shear-thinning rheological properties with yield value and positive sensory perception.
According to Ashland, it offers emulsion stabilization, reduces tack and improves aesthetics of hydroalcoholic sprays, and enhances skin feel properties.
