Dodecanol (Lauryl Alcohol/L-23) is widely used in five major fields: surfactant synthesis, personal care products, industrial cleaning, textile and leather auxiliaries, and fine chemical intermediates.

Overview of Industry and Process Applications

Application IndustrySpecific Process/UseFunction Description
Surfactant IndustrySulfonation/Sulfation → Production of SLS, SLES; Ethoxylation → Production of AEO seriesActs as a core hydrophobic raw material to construct anionic and non-ionic surfactants, used in shampoos, shower gels, toothpaste, and industrial cleaners
Personal Care and CosmeticsEmulsification, thickening, esterification synthesis (e.g., dodecyl lactate)Auxiliary emulsifier and thickener, stabilizing the oil-water interface of creams/lotions; precursor of emollient esters, softening the stratum corneum
Household and Industrial CleaningFormulation blending in liquid detergents, precision cleaning of electronic/metal partsDegreasing and decontamination, foam control; degreasing cleaning using solubility and volatility balance
Textile Dyeing, Printing, and LeatherFiber smoothing and finishing, leather fatliquoring processRaw material for synthesizing softeners/antistatic agents, reducing fiber friction coefficient; lubricating and separating leather fibers, imparting soft and full texture
Lubricant and Plastics IndustryEsterification → Synthesis of lubricant esters; plasticizer intermediateProvides lubricity and thermal stability; improves processing flexibility of polymers
Flavor and Fragrance, PharmaceuticalsOxidation → Dodecanal; Esterification → Dodecanoate; Drug modificationPreparation of waxy/floral fragrance notes; as a hydrophobic long-chain alkyl group introducer, involved in the synthesis of drug delivery carriers

Core Process Routes

Dodecanol, as a C12 linear saturated primary alcohol (CAS: 68439-50-9), derives its process value from the highly reactive hydroxyl group. The main process routes include: ethoxylation (addition reaction with ethylene oxide to produce AEO series), sulfation/sulfonation (to produce SLS/SLES anionic surfactants), esterification (to produce lubricating esters, plasticizers, and flavor esters), and oxidation (to produce dodecanal, a fragrance intermediate).

Key Notes

This product is classified under GHS as Skin Irritant Category 2, Eye Irritant Category 2, and Acute Aquatic Toxicity Category 1 (H315/H319/H410). Protective equipment must be worn during handling, and discharge into natural water bodies without treatment is strictly prohibited. Storage temperature is recommended to be below 40°C to avoid container deformation due to melting/solidification.
