Description

Ethyl Stearate is a fatty acid ester derived from stearic acid and ethanol, known for its excellent lubricity and hydrophobic properties. This versatile compound serves as a key intermediate and functional additive across numerous high-value manufacturing sectors. It is essential for industries requiring reliable emollients, plasticizers, lubricants, or chemical synthesis building blocks.

Application

• Personal Care & Cosmetics: Acts as a non-greasy emollient and texture enhancer in creams, lotions, and makeup formulations.
• Plastics & Polymers: Functions as an internal lubricant and plasticizer to improve processing and flexibility in PVC and other polymer systems.
• Lubricants & Metalworking: Used as a synthetic base oil or additive in specialty lubricants, drawing compounds, and release agents.
• Food Industry: Employed as a lubricant in food processing machinery and as a component in food-grade release agents (where compliant).
• Textile & Leather: Serves as a softening agent and waterproofing finish for fibers, fabrics, and leather goods.
• Chemical Synthesis: Utilized as a chemical intermediate for producing other esters, surfactants, and specialty chemicals.
