Guoli Chemical's Dodecanol/Lauryl Alcohol 12 Alcohol L-23 (CAS: 68439-50-9) is a mixture of straight-chain saturated primary alcohols with C12 as the main component and a small amount of C14. At room temperature, it appears as a colorless liquid or white waxy solid (melting point 23~25°C). As a long-chain fatty alcohol, its molecular structure possesses both a hydrophobic long carbon chain and a reactive hydroxyl group, naturally endowing it with excellent emulsifying, wetting, and dispersing capabilities. It serves as the core hydrophobic group source for synthesizing various anionic and nonionic surfactants.
In terms of chemical reactivity, L-23 exhibits all the typical chemical properties of primary alcohols and can smoothly participate in various derivatization reactions such as ethoxylation, sulfation, and esterification, offering flexible synthesis pathways that conveniently convert it into high value-added products like sodium dodecyl sulfate (SLS), lauryl alcohol polyoxyethylene ether (AEO series), and sodium lauryl ether sulfate (SLES). Meanwhile, its high purity (≥99% active content) and narrow carbon chain distribution ensure high batch-to-batch consistency in downstream formulations.
With its balanced hydrophilic-lipophilic properties (HLB value approx. 1.3), L-23 can be used directly as a co-emulsifier and thickener in cream and lotion formulations, or as a precursor for emollient esters in personal care products. Its low degree of unsaturation (iodine value ≤1) and good chemical stability allow it to maintain excellent quality even under high temperature or long-term storage conditions.
