Leading company of "acrylic ester" home Business / Products Functional chemicals Betaine polymer Functional chemicals Functional Polymer RAM resin series Betaine polymer Cosmetic ingredients Display name (Ethyl Methacrylate Betaine / Acrylate) Copolymer INCI name METHACRYLOYL ETHYLBETAINE / ACRYLATES COPOLYMER Chemical name N-methacryloyloxyethyl-N, N-dimethylammonium-α N-methylcarboxybetaine / methacrylic acid alkyl ester copolymer Structural formula Features The RAM resin series has a betaine unit in the polymer structure. Polymers with this betaine unit behave peculiarly unlike other ionic polymers. For example, when a polymer is dissolved in water, the pH of the system dissolves on both the acidic and alkaline sides. In addition, it is not easily affected by additives, and in particular, it has the characteristic that the polymer does not easily precipitate even if an electrolyte is added to the aqueous solution. It can also be used as an additive for primary hair dyes by taking advantage of its properties such as dispersibility of dyes and formation of complexes.
