Steareth-20 methacrylate

Steareth-20 methacrylate (CAS 52352-43-9), also known as polyethylene glycol monooctadecyl ether monomethacrylate, is a polymerizable macromonomer combining a hydrophobic stearyl tail with a 20-unit ethoxylate chain.

Where is Steareth-20 methacrylate used?

• Personal care: copolymerized into associative thickeners for rheology control in lotions, conditioners and styling products
• Home care and industrial cleaning: polymer systems improving suspension stability and surface wetting in liquid detergents and hard-surface cleaners
• Textile and paper: copolymers modify fiber surface properties, improving softness, water repellency or dye uptake
• Emulsion polymerization: ethoxylate segment contributes emulsification performance, stabilizing the latex particle interface
• It is a building block for associative polymers and surface-active copolymers.

Good to know: Inhibited grades containing polymerization inhibitors for storage stability are standard for formulation development and large scale chemical manufacturing.
