Polyquaternium Crosspolymer-3 is a chemical compound, the polymeric quaternary ammonium compound formed from trimethylaminoethylmethacrylate chloride and PEG-45 crosslinked with methylene bis-acrylamide.

The name describes the structure of the molecule.

• Polyquaternium is a class of chemical compounds primarily used in hair and skin care products. They are cationic polymers that can help condition and increase viscosity.
• Crosspolymer indicates that the polymer has cross-links, which can give the polymer unique properties such as strength and elasticity.
• 3 is a sequential designation indicating a specific variant or type within the polyquaternium family.

Description of raw materials used in production.

• Trimethylaminoethylmethacrylate Chlorid. A monomer with a quaternary ammonium structure that imparts cationic properties to the polymer.
• PEG-45. A mid-molecular weight polyethylene glycol, utilized to give hydrophilic properties to the polymer.
• Methylene bis-acrylamide. A crosslinking agent that links polymer chains together, giving the polymer a three-dimensional structure.

Step-by-step summary of its industrial production process.

• Trimethylaminoethylmethacrylate chloride and PEG-45 are mixed in a suitable reactor.
• An initiator is added to start the polymerization reaction.
• During polymerization, methylene bis-acrylamide is introduced to crosslink the polymer chains.
• Once polymerization is complete, the product is purified and filtered to remove any impurities.
• The resulting polymer is then formulated into the desired form for use in final products.

Polyquaternium Crosspolymer-3 typically presents as a gel or a viscous liquid, ranging from clear to cloudy depending on the specific formulation and concentration.

What it is used for and where

Cosmetics

Due to its cationic and hydrophilic properties, this polymer finds use in various hair and skin care products like shampoos, conditioners, lotions, and creams, where it provides conditioning and film formation.

Viscosity control agent. It controls and adapts viscosity to the required level for optimal chemical and physical stability of the product and dosage in gels, suspensions, emulsions, solutions.

Hair Products. It might be used in hair products such as conditioners, masks, and styling products to improve combability and provide body and volume.

Skin Products. In creams, lotions, and other skincare products, it might act as a conditioning agent, providing a soft feel.

Stabilizing Agent. Might function as a stabilizer in some cosmetic formulations.

Film Forming. Could assist in forming a protective film on the skin or hair, retaining moisture.
