Description

2-[2-[2-[(1-Oxohexadecyl)Oxy]Ethoxy]Ethoxy]Ethyl Stearate is a high-purity, non-ionic surfactant and emollient ester derived from ethoxylated stearyl alcohol and stearic acid. This specialized chemical is valued for its excellent emulsifying properties, skin-feel enhancement, and stability in complex formulations. It is primarily utilized by manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking reliable performance ingredients.

Application

• Primary Emulsifier and Co-emulsifier in creams, lotions, and ointments for personal care.
• Skin Conditioning Agent providing a smooth, non-greasy emollient feel in cosmetic formulations.
• Viscosity Modifier and Stabilizer in water-in-oil (W/O) and oil-in-water (O/W) emulsion systems.
• Lubricant and Plasticizer in specialty industrial applications and polymer processing.
• Base Material for synthesizing more complex ester derivatives in fine chemical production.
• Additive in textile auxiliaries and fiber lubricants to improve processing.
