Stearic Acid

Whatsapp Order

Stearic Acid (Triple Pressed) is a high-purity, saturated fatty acid derived primarily from vegetable fats. The triple pressing process enhances its purity, resulting in a fine, waxy solid with excellent consistency and reduced impurities. It is widely used as an emulsifier, thickener, and surfactant in various industries, providing stability and texture to products ranging from cosmetics to rubber and plastics.
