Lauryl-myristyl alcohol brings together two fatty alcohols—dodecanol (lauryl alcohol) and tetradecanol (myristyl alcohol)—into a single material with broad applications. Used across personal care, cleaning, and manufacturing, this compound stands out because of its balanced chain length, bridging the gap between shorter and longer fatty alcohols. The structure is straightforward: a long hydrocarbon chain ending in a hydroxyl group, giving it nonionic surfactant characteristics. Its molecular formula commonly reflects the blend of C12 and C14 alcohols, ranging from C12H26O to C14H30O, depending on the proportion. This combination offers a dense, solid touch at room temperature, breaking down easily into flakes or pellets for easier handling and mixing.
In the market, lauryl-myristyl alcohol usually appears as white or slightly off-white flakes, fine powders, pearls, or solid chunks. Under specific temperature conditions, it melts into a clear or slightly cloudy liquid. Most supply formats focus on solid forms because of higher shelf stability but liquid variants often see use in industrial blending. Some companies offer crystal-clear solutions, and in laboratories, measuring out one liter of this material guarantees consistent quality each batch. Companies source it as raw material for emulsifiers, emollients, and thickeners. The flakes and pearls dissolve easily and blend smoothly into formulations such as creams, shampoos, and detergents.
The structure of lauryl-myristyl alcohol gives it surface-active properties—lowering surface tension between different substances—thanks to the hydrophilic hydroxyl group and hydrophobic carbon chain. This duality lets it anchor oil and water together, vital for stable emulsions in lotions and cleansers. Specifications for industry often call for a carbon chain spread—typically a 70/30 or 50/50 mix—ensuring a melting point that fits product needs. Purity often comes in around 98-99%, with density in the range of 0.81-0.83 g/cm³ as a solid. At higher temperatures, the material becomes less dense and transforms into a near-colorless liquid. This wide range of melt points and densities makes it versatile for a host of industries, from personal care to pharmaceuticals.
Customs classify lauryl-myristyl alcohol under HS Code 2905.17, which covers fatty alcohols, including their blends and derivatives. Accurate classification matters for import, export, and safety documentation. Compliance with regional regulations—like REACH in Europe or TSCA in the United States—prevents unnecessary border delays. Certain markets require a material safety data sheet (MSDS), noting specific handling measures and labeling, helping workers and consumers understand risks and precautions.
While lauryl-myristyl alcohol is neither acutely toxic nor corrosive at usual concentrations, handling raw material in bulk or inhaling dust during processing may irritate eyes, skin, or respiratory tracts—common for fatty alcohols. Proper personal protective equipment, including gloves and masks, keeps risk low. Despite being less hazardous than solvents or caustics, accidental release can affect waterways; so, containment measures, including spill kits and training, matter in manufacturing sites. The compound’s biodegradability adds a measure of reassurance in eco-sensitive sectors, but overuse in wash-off formulations means wastewater systems still must address fatty buildup. Companies that use this raw material often adopt closed-process systems to minimize airborne dust and improve worker safety.
Lauryl-myristyl alcohol’s molecular size—compared to shorter alcohols—lends it a creamy texture when melted, making it a popular choice as a base for cosmetic butters and soft waxes. Unlike the liquid feel of shorter alcohols, its solid, waxy touch at room temperature creates thicker, more substantive products. The melting point, usually between 28°C to 38°C depending on the blend, means even minor environmental changes can shift its texture from solid to liquid. This property helps formulators dial in product performance, from stiffer sticks to more emollient creams. Its nonionic charge sidesteps compatibility issues present in other surfactants, making it a team player in multi-component blends. Solubility in water remains low, but it dissolves completely in hot oils and common organic solvents.
My experience on shop floors and with bulk suppliers shows that lauryl-myristyl alcohol is more than a minor additive. In the world of cosmetics, it creates spreadable, stable emulsions that hold their form in creams, conditioners, and balms. Household cleaners use it to lift greasy soils from hard surfaces. Some pharmaceutical ointments use it as a thickener that stabilizes ingredients without causing irritation. Industrial applications turn to this alcohol for its lubricity and antistatic qualities. Its moderate melting point means storage and transport require some care, but standard warehouse conditions suit it well. Most suppliers ship in drums or bags lined to prevent contamination—protecting both product and people who handle it. For production managers faced with tight specs and demanding clients, this fatty alcohol’s balance of safety, performance, and availability makes it a daily essential.
Wide use does not excuse carelessness. Training staff on proper handling, dust reduction, and spill containment cuts down health and fire risks. Facilities that invest in local extraction systems and personal protective gear see fewer incidents. Moving toward upgraded, closed-system manufacturing reduces exposure, both for workers and the environment. Documentation stays up to date with global chemical regulation, so that finished goods—shipped across borders—meet all safety and labeling standards. For end-users, clear labeling on household products ensures shoppers understand ingredients, helping them make informed choices. Raw material buyers check batch records for traceability, holding suppliers accountable for purity and compliance.
