Description

2-Propenoic Acid, 2-Methyl-, 2-(Diethylamino) Ethyl Ester, Homopolymer Compound With Methyl 4-Methylbenzenesulfonate CAS NO 63812-78-2 is a specialized cationic polymer derived from a dimethylaminoethyl methacrylate (DMAEMA) homopolymer, quaternized with methyl p-toluenesulfonate. This compound is valued for its strong positive charge and film-forming properties, making it an effective agent for modifying surface interactions and stability. It is primarily sought by manufacturers in the personal care, coatings, and specialty chemical industries for applications requiring cationic functionality, adhesion promotion, and rheology control.

Application

• Hair Care & Styling Products: As a cationic conditioning polymer in shampoos, conditioners, and hairsprays to improve manageability, reduce static, and enhance hold.
• Cosmetic Formulations: Used in skincare products like creams and lotions for its emulsifying and film-forming properties, improving texture and skin feel.
• Industrial & Protective Coatings: Acts as a dispersant, adhesion promoter, and rheology modifier in water-based paints, primers, and industrial coatings.
• Textile & Leather Processing: Employed as a softening agent, antistatic agent, and dye-fixing auxiliary to improve fabric hand and color fastness.
• Paper Manufacturing: Functions as a retention aid, drainage aid, and strength additive in paper coating and wet-end chemistry.
• Adhesives & Sealants: Enhances tack, adhesion, and viscosity stability in pressure-sensitive and water-based adhesive systems.
• Water Treatment: Utilized as a flocculant and coagulant aid in the clarification process for industrial wastewater.
• Pharmaceutical Excipients: Potential use in controlled-release drug delivery systems as a film-coating agent or matrix former.
