Dimethylaminoethyl Methacrylate

Product Description

Our Dimethylaminoethyl Methacrylate is high-purity cosmetic-grade monomer from direct factory supply, stabilized with Typical polymerization inhibitor and supplied with batch COA traceability for film-forming polymer manufacturers.

This cationic methacrylate ester copolymerizes with acrylates and VP monomers to build flexible, adhesive films on hair and skin substrates, delivering hold, wear resistance, and viscosity control in styling and color cosmetic systems.

CosIng-listed DMAEMA meets demand for amino-functional methacrylate building blocks in hair fixatives and long-wear makeup polymers, offering cationic binding depth beyond generic acrylate monomers without tertiary amine functionality.

Key Benefits & Applications

Dimethylaminoethyl Methacrylate delivers cationic methacrylate functionality for formulators building hair fixative, long-wear makeup, and film-forming polymer systems.

• Film formation: Cationic methacrylate monomer builds flexible hold copolymers for hair fixative and styling spray systems.
• Adhesive wear: Dimethylamino groups enhance substrate binding in long-wear eyeliner and brow film formulations.
• Viscosity control: Modulates polymer matrix flow during copolymer synthesis and finished gel-base processing.
• Cationic binding: Supports durable film adhesion on hair keratin in VP-acrylate copolymer styling systems.

Formulation Guidelines

Use as copolymerization monomer in film-forming polymer synthesis; maintain inhibitor stabilization; avoid heat, light, and peroxide initiator overload during bulk handling.

• Recommended use level: 5–30% in copolymer synthesis feed; finished polymer use per supplier Typical guidance.
• Optimal formula pH: N/A — polymerization-stage monomer; neutralize finished copolymer as required.
• Processing: Store below 8°C; polymerize under inert atmosphere with MEHQ inhibitor; avoid uncontrolled exotherm.
• Compatibility: Copolymerizes with acrylates, VP, and methacrylic esters in alcohol or aqueous dispersion systems.
• Caution: Light- and heat-sensitive; use explosion-proof handling; not for direct neat leave-on consumer application.
• Synergy: Pair Acrylates Copolymer with DMAEMA monomer to build flexible hold films in hair styling systems.
