Description

1-Decanol, 2-Octyl- is a branched-chain fatty alcohol, also known by its CAS number 45235-48-1. This specialty chemical is valued for its unique structure which imparts properties such as low volatility and excellent solvency, making it a versatile intermediate and performance additive. It is primarily sought after by manufacturers in the personal care, lubricant, and polymer industries for its ability to modify rheology, enhance stability, and act as a non-ionic surfactant precursor.

Application

• Personal Care & Cosmetics: Used as an emollient, viscosity modifier, and carrier oil in creams, lotions, and sunscreens.
• Lubricants & Greases: Serves as a synthetic base oil or additive to improve lubricity, thermal stability, and corrosion protection.
• Polymer & Plastic Additives: Acts as a processing aid, plasticizer, or intermediate for stabilizers and antioxidants.
• Surfactant Synthesis: A key raw material for producing high-performance, branched non-ionic surfactants and emulsifiers.
• Metal Working Fluids: Incorporated as a lubricity enhancer and corrosion inhibitor in cutting and grinding fluids.
• Chemical Intermediate: Utilized in organic synthesis for pharmaceuticals, agrochemicals, and specialty esters.
