Acrylamide/ethyltrimonium chloride acrylate/ethalkonium chloride acrylate copolymer is a chemical compound, quaternised polymer, with trimonio-containing repeating units.
The name describes the structure of the molecule:
- Acrylamide is an organic monomer used in the production of polymers, particularly polyacrylamide. It's known for its gel-forming properties and is often used in cosmetics and hair care products for its conditioning and thickening properties.
- Ethyltrimonium chloride acrylate is a cationic monomer that can interact with negatively charged surfaces, like hair. It can enhance the polymer's adherence to hair and provide conditioning.
- Ethalkonium chloride acrylate. Similar to ethyltrimonium chloride acrylate, it's another cationic monomer used for its conditioning and adherence properties.
- Copolymer indicates that the polymer is formed from more than one type of monomer. Copolymers can combine the properties of individual monomers to achieve desired characteristics in the final product.
Raw Materials Used in Production.
- Acrylamide. A white crystalline chemical compound.
- Ethyltrimonium Chloride Acrylate. A quaternary salt used for polymer production.
- Ethalkonium Chloride Acrylate. Another quaternary salt utilized in polymer production.
Step-by-step Summary of Industrial Production Process.
- Preparation of Raw Materials: Raw materials are measured and mixed in the correct proportions.
- Polymerization: Under controlled conditions, a polymerization reaction occurs among the raw materials.
- Purification: The product is purified to remove any impurities.
- Drying: The copolymer is dried to remove moisture.
- Granulation or Grinding: The product is granulated or ground into the desired form.
Form and Color.
Typically, it is a powder or granules of varied color depending on the application and formulation.

What it is used for and where
Cosmetics
It is a restricted ingredient as III/66 a Relevant Item in the Annexes of the European Cosmetics Regulation 1223/2009. Substance or ingredient reported: Polyacrylamides
Film-forming agent. Produces a very thin continuous film with an optimal balance of cohesion, adhesion and adhesiveness on skin or hair.
Hair conditioning agent. A large number of ingredients with specific purposes can co-exist in a hair shampoo: cleansers, conditioners, thickeners, mattifying agents, sequestering agents, fragrances, preservatives, special additives. However, the indispensable ingredients are the cleansers and conditioners as they are necessary and sufficient for hair cleansing and manageability. The others act as commercial and non-essential auxiliaries such as: appearance, fragrance, colouring, etc. Hair conditioning agents have the task of increasing shine, manageability and volume, and reducing static electricity, especially after treatments such as colouring, ironing, waving, drying and brushing. They are, in practice, dispersing agents that may contain cationic surfactants, thickeners, emollients, polymers. The typology of hair conditioners includes: intensive conditioners, instant conditioners, thickening conditioners, drying conditioners.
Skin conditioning agent - Miscellaneous. This ingredient has the task of modifying the condition of the skin when it is damaged or dry by reducing its flakiness and restoring its elasticity.
Slip modifier. It increases the spreadability of a product by helping other substances flow more smoothly and easily, without chemical reaction.
Viscosity Enhancing Agent - aqueous. Since viscosity is important for increasing the chemical and physical stability of the product, Viscosity Enhancing Agent acqueous is an important dosage factor in gels, suspensions, emulsions, solutions. Increasing viscosity makes formulations less sedimentary and more homogeneously thickened.
