Lauryl Alcohol C12-99
Lauryl Alcohol C12-99
Lauryl Alcohol, also recognized as dodecanol or C12 alcohol, possesses the chemical formula C₁₂H₂₅OH. It is procured from palm kernel fatty acids through esterification and catalytic hydrogenation and is classified as a mid-cut alcohol. Lauryl Alcohol manifests as a white crystalline solid below 22–24°C and is typically obtained from natural vegetable oils such as coconut oil or palm kernel.
Lauryl Alcohol is a saturated 12-carbon fatty alcohol manufactured from fatty acids found in palm kernel or coconut oil. It possesses a floral scent and is commonly employed in detergents, lubrication oils, and pharmaceuticals.
Lauryl Alcohol is manufactured industrially from fatty acids through esterification followed by catalytic hydrogenation. It functions as a foundational feedstock in the fabrication of surfactants and detergents—encompassing anionic, nonionic, and cationic varieties—as well as tertiary amines, fabric softeners, metalworking lubricants, disinfectants, and biocides.
Sulfate esters of Lauryl Alcohol, particularly sodium lauryl sulfate, are extensively employed as surfactants in items such as shampoos. Variants like ammonium lauryl sulfate and sodium lauryl sulfate are frequently utilised. Lauryl Alcohol itself is tasteless, colourless, and possesses a floral scent.
Its applications encompass feedstocks for surfactants, conditioners, disinfectants, and plasticizers. It additionally functions as an oil base for lubricants in synthetic resin production, emulsifiers in emulsion polymerization, and a feedstock for creams, ointments, and metal rolling oils.
