Description

Decyl 16-Methylheptadecanoate is a high-purity synthetic ester derived from branched-chain fatty acids. This specialty chemical serves as a premium emollient and lubricant, valued for its excellent oxidative stability and skin-feel properties in demanding formulations. It is primarily sought by manufacturers in the personal care, cosmetics, and high-performance lubricant industries for its unique combination of performance and compatibility.

Application

• Personal Care & Cosmetics: Acts as a high-end emollient and skin-conditioning agent in creams, lotions, sunscreens, and lipsticks, providing a non-greasy, silky feel.
• Lubricants & Greases: Used as a synthetic base oil or additive in specialty lubricants requiring high thermal stability and low volatility.
• Plasticizers: Functions as a secondary plasticizer or lubricant in polymer processing, particularly for PVC and other resins.
• Textile Auxiliaries: Employed as a softening agent and lubricant in fiber and fabric treatment processes.
• Metalworking Fluids: Serves as a lubricity additive in synthetic and semi-synthetic cutting and grinding fluids.
• Release Agents: Used in mold release formulations for plastics, rubber, and composite materials.
