The core applications of Dodecanol/Lauryl Alcohol 12 Alcohol L-23 cover multiple fine chemical industries and process stages, including surfactants, personal care, industrial cleaning, textile and leather, lubricants and plastics, flavors and fragrances, and pharmaceutical intermediates.

Detailed Description

Dodecanol_Lauryl Alcohol 12 Alcohol L-23 (CAS: 68439-50-9) is an important C12-14 fatty alcohol that holds a key raw material position in the fine chemical industry due to its high purity, excellent surface activity, and high reactivity. It can be directly used as an auxiliary agent in formulations and serves as a crucial intermediate for synthesizing various derivative chemicals. Its applications span multiple industries, including daily chemicals, textiles, leather, cleaning, flavors and fragrances, and pharmaceuticals.

In the surfactant industry, dodecanol is the core hydrophobic raw material for preparing anionic surfactants (e.g., sodium lauryl sulfate SLS, sodium lauryl ether sulfate SLES) through sulfonation or sulfation reactions, widely used in shampoos, body washes, and industrial cleaners; simultaneously, it can be ethoxylated to produce nonionic fatty alcohol polyoxyethylene ethers (AEO series), applied in textiles and papermaking. In personal care and cosmetics, it is directly used as a co-emulsifier, thickener, and emollient carrier, providing stable structure and a fine skin feel for creams and lotions. In industrial auxiliaries and additives, it is a basic raw material for textile smoothing agents, softeners, and leather fatliquoring agents; its derived esters are also important components of high-grade lubricants and plastic plasticizers.

Furthermore, in the field of organic synthesis, dodecanol can be converted into flavor and fragrance intermediates such as dodecanal and dodecanoate esters through oxidation, esterification, and other processes. It can also serve as a pharmaceutical intermediate by introducing a hydrophobic long-chain alkyl group for modification of drug delivery carriers and biodegradable materials, demonstrating high process application value.

Application Recommendations

  • Formulation Application: When used as a co-emulsifier and thickener in personal care formulations, it is recommended to combine with other primary emulsifiers (e.g., fatty alcohol polyoxyethylene ethers) to achieve a more stable emulsion system. As a starting raw material for surfactant synthesis, the process route (sulfonation, sulfation, or ethoxylation) should be selected based on the target product, with precise control over molar ratios and reaction conditions.
  • Handling & Storage: The product has a melting point of 23-25°C and may be solid at low temperatures. Before use, it can be slowly melted using a warm water bath (below 40°C) to avoid localized overheating. Store in a tightly closed container in a cool, dry place, away from strong oxidizing agents.
  • Industrial Versatility: Due to its high purity (≥99%) and narrow carbon chain distribution, it ensures high batch-to-batch consistency of downstream derivatives, especially suitable for pharmaceutical and flavor & fragrance synthesis processes demanding high quality stability.

Precautions

  • Health & Safety: This substance causes skin irritation (H315) and serious eye irritation (H319). During handling, protective gloves, protective clothing, and safety goggles must be worn, and adequate ventilation must be ensured. If skin contact occurs, wash with plenty of soap and water. If it enters the eyes, rinse carefully with water for several minutes and seek medical attention.
  • Environmental Hazards: Very toxic to aquatic life with long-lasting effects (H410). Do not discharge the product or wastewater containing it directly into water bodies. In case of spillage, collect immediately; waste gas and liquid must be incinerated at a licensed treatment facility. Do not discard or landfill arbitrarily.
