Description

Ethyl Isostearate is a high-purity ester derived from isostearic acid and ethanol, valued for its excellent emolliency, low viscosity, and superior oxidative stability. This versatile chemical intermediate is engineered to enhance product performance by providing exceptional lubricity, skin feel, and formulation compatibility. It is a critical ingredient for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking reliable, high-quality raw materials.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup formulations.
• Hair Care Products: Used as a glossing and conditioning agent in hair serums, pomades, and leave-in treatments to reduce frizz and improve manageability.
• Plasticizers & Polymers: Serves as a secondary plasticizer and lubricant in PVC and other polymer processing to improve flexibility and processing characteristics.
• Specialty Lubricants: Functions as a synthetic base oil or additive in high-performance lubricants, greases, and metalworking fluids due to its thermal stability.
• Textile & Leather Processing: Employed as a softening and lubricating agent for fibers, yarns, and leather finishes.
• Industrial Coatings & Inks: Utilized as a leveling and flow agent to improve the application properties and final finish of coatings and printing inks.
