Dodecanol (Lauryl Alcohol) L-23 is a high-purity C12-14 linear saturated fatty alcohol, serving as a core fine chemical raw material for synthesizing surfactants, personal care products, and various industrial auxiliaries.
Detailed Description
Dodecanol, commonly known as Lauryl Alcohol, with CAS number 68439-50-9 and chemical formula C₁₂H₂₆O, is an important linear saturated fatty alcohol. Supplied by Guoli Chemical, it appears as a colorless liquid or white waxy solid at room temperature, characterized by high purity and narrow carbon chain distribution, ensuring excellent batch-to-batch stability in downstream formulations.
As a nonionic surfactant, Dodecanol has an HLB value of approximately 1.3, exhibiting excellent emulsifying, wetting, and dispersing capabilities. The primary hydroxyl group in its molecular structure endows it with high reactivity, allowing easy derivatization reactions such as ethoxylation, sulfation, and esterification. It is the core backbone raw material for producing products like sodium dodecyl sulfate and AEO series nonionic surfactants.

Application Suggestions
- Surfactant Synthesis: As a core hydrophobic raw material, used to synthesize anionic surfactants (e.g., SLS/SLES) and nonionic surfactants (e.g., AEO series), widely applied in shampoos, body washes, toothpaste, and industrial cleaners.
- Personal Care Products: Can be used as a co-emulsifier, thickener, and emollient in creams, lotions, and other formulations, providing a fine skin feel and stable structure.
- Industrial Auxiliaries: As a basic raw material for textile smoothing agents, leather fatliquoring agents, lubricant additives, and plasticizer intermediates, enhancing softness, lubricity, and processing performance of products.
- Organic Synthesis Intermediates: Can be oxidized or esterified to produce dodecanal, dodecanoate esters, etc., used in daily chemical flavors and food flavoring.
Precautions
