Description

2-Methyl-2-[(1-Oxo-2-Propenyl)Amino]-1-Propanesulfonic Acid Homopolymer Potassium Salt is a high-purity, water-soluble polymer derived from the monomer AMPS (2-acrylamido-2-methylpropanesulfonic acid). This compound is valued for its exceptional anionic charge density, thermal stability, and resistance to hydrolysis, making it a critical performance additive. It is primarily used by formulators and manufacturers in industries requiring advanced rheology control, scale inhibition, and dispersion. This product is supplied as a potassium salt to ensure optimal solubility and handling characteristics for demanding industrial applications.

Application

• Enhanced Oil Recovery (EOR): Acts as a viscosifier and mobility control agent in polymer flooding operations.
• Water Treatment: Serves as a highly effective antiscalant and dispersant for calcium carbonate and sulfate scales in cooling water and boiler systems.
• Personal Care & Cosmetics: Utilized as a film-forming agent, thickener, and stabilizer in hair gels, creams, and lotions for superior hold and texture.
• Textile & Dyeing: Functions as a leveling agent and dispersant for dyes and pigments, improving color uniformity and fastness.
• Paints & Coatings: Provides excellent pigment dispersion and stabilization, enhancing color development and shelf-life of aqueous formulations.
• Construction Chemicals: Used as a superplasticizer and rheology modifier in cement and concrete admixtures to improve workability and reduce water content.
• Industrial Detergents: Enhances cleaning power and soil suspension in heavy-duty liquid and powder detergents.
• Pharmaceuticals: Employed as an excipient in controlled-release drug delivery systems and topical formulations.

Quality Control

Our production of 2-Methyl-2-[(1-Oxo-2-Propenyl)Amino]-1-Propanesulfonic Acid Homopolymer Potassium Salt adheres to stringent quality management systems. Every batch is characterized for critical parameters including molecular weight distribution, degree of polymerization, and ionic content to ensure consistent performance. Certificates of Analysis (COA) documenting purity, assay, and key physical properties are provided with each shipment. We support compliance with relevant industry standards and can tailor specifications to meet specific GMP, ISO, or REACH requirements for our global clientele.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced performance. Keep away from incompatible materials such as strong oxidizing agents.
