Pemulen™ 1621 polymer

Pemulen™ 1621 polymer is a moderately crosslinked, hydrophobically-modified, polyacrylic acid polymer powder polymerized in a toxicologically-preferred cosolvent system. It was designed to form stable oil-in-water emulsions at low use levels. It is a cost-effective polymer for medium viscosity emulsions recommended for use in automotive care, polishes, and protectants.
