Description

Aluminum Monostearate is a white, fine powder widely recognized as a versatile metallic soap and gelling agent. Its primary value lies in its ability to thicken, stabilize, and impart water-repellent properties to various formulations. This compound is essential for manufacturers in the cosmetics, pharmaceuticals, paints, and plastics industries seeking to control viscosity and improve product texture and stability.

Application

• Cosmetics & Personal Care: Acts as a thickener, stabilizer, and opacifying agent in creams, lotions, deodorants, and makeup products.
• Pharmaceuticals: Used as a gelling and stiffening agent in topical ointments, creams, and as a tablet lubricant.
• Paints & Coatings: Functions as a flatting and suspending agent, preventing pigment settling and improving application properties.
• Plastics & Polymers: Serves as an acid scavenger, lubricant, and anti-caking agent in PVC and other polymer processing.
• Greases & Lubricants: Employed as a thickening agent to produce consistent, water-resistant lubricating greases.
• Construction Materials: Used in waterproofing agents and as an additive in cement and concrete formulations.

Quality Control

Our Aluminum Monostearate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for parameters such as aluminum content, stearic acid content, loss on drying, and particle size distribution. Certificates of Analysis (COA) documenting these results are provided to guarantee consistency, purity, and performance for your industrial applications.

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 product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
