Description

Poly(Malate) CAS NO 78644-42-5 is a biodegradable, water-soluble polymer derived from malic acid, offering a sustainable alternative to traditional petrochemical-based materials. Its unique structure provides excellent chelating, dispersing, and moisture-retention properties, making it highly valuable in advanced formulations. This polymer is essential for manufacturers in the personal care, agriculture, and water treatment industries seeking high-performance, eco-friendly ingredients.

Application

• Personal Care & Cosmetics: Acts as a highly effective humectant and skin-conditioning agent in moisturizers, serums, and hair care products.
• Agriculture: Serves as a key component in foliar fertilizers and biostimulants, enhancing nutrient uptake and plant stress tolerance.
• Water Treatment: Functions as a biodegradable scale and corrosion inhibitor in cooling and boiler water systems.
• Industrial Cleaning: Used in formulations for descaling agents and detergents due to its superior chelating power against calcium and magnesium ions.
• Pharmaceuticals: Employed as an excipient in drug delivery systems for its biocompatibility and controlled-release properties.
• Textile Processing: Utilized as a dispersing agent and anti-redeposition aid in dyeing and finishing operations.

Quality Control

Our Poly(Malate) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, residual monomers, and heavy metal content are provided with every shipment to guarantee compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
