Description

Isopropyl Stearate is a high-purity, synthetic ester derived from stearic acid and isopropyl alcohol. This versatile compound serves as an excellent emollient, lubricant, and solvent, valued for its low viscosity, non-greasy feel, and excellent spreading properties. It is a critical ingredient for formulators in the personal care, cosmetics, pharmaceutical, and industrial lubricant sectors seeking reliable performance and skin compatibility.

Application

• Cosmetics & Personal Care: A key emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup, providing a smooth, silky after-feel.
• Pharmaceuticals: Used as a lubricant in tablet manufacturing and as a carrier or solvent in topical ointments and transdermal delivery systems.
• Industrial Lubricants & Release Agents: Functions as a synthetic lubricant base, mold release agent for plastics and rubber, and a textile fiber lubricant.
• Plasticizers & Additives: Acts as a secondary plasticizer and processing aid in polymer and resin formulations to improve flexibility and workability.
• Metalworking Fluids: Employed as a component in cutting and drawing oils for its lubricity and corrosion inhibition properties.
• Food Contact Applications: Used as a lubricant and release agent in food processing machinery and packaging materials (subject to specific grade and regulatory compliance).
