Hexadecyl/Octadecyl Alcohol, commonly referred to as C16/C18 fatty alcohols, are organic compounds that hold significant importance in various industrial sectors. As a premier manufacturer and supplier in China, NINGBO INNO PHARMCHEM is pleased to offer these vital chemical intermediates, recognized for their high purity and consistent quality. For R&D scientists and formulators, understanding the underlying chemistry of these fatty alcohols is key to unlocking their full potential.

Chemically, Hexadecyl Alcohol (C16H33OH) and Octadecyl Alcohol (C18H37OH) are classified as long-chain primary aliphatic alcohols. They share a general formula of R-OH, where 'R' represents a long alkyl chain. The 'C16' and 'C18' designation refers to the number of carbon atoms in this chain. This extended hydrocarbon chain is largely nonpolar, making these alcohols hydrophobic, while the terminal hydroxyl (-OH) group is polar, imparting some hydrophilic character. This amphipathic nature is fundamental to many of their applications, particularly in surfactant chemistry.

At room temperature, Hexadecyl and Octadecyl alcohols typically exist as white, waxy solids or flakes. Their melting points differ slightly, with Hexadecyl alcohol melting around 49-50°C and Octadecyl alcohol around 56-59°C. This physical property influences their use in formulations; a mixture like the C16/C18 blend can offer a desirable melting range for applications such as cosmetic bases and solid lubricants. The low volatility and relatively high flash points also contribute to their safe handling and use in various industrial processes.

The chemical reactivity of fatty alcohols is primarily associated with the hydroxyl group. This functional group can undergo a variety of reactions, including esterification, ethoxylation, sulfation, and oxidation. Esterification with fatty acids yields esters, which are widely used as emollients and lubricants. Ethoxylation, the reaction with ethylene oxide, produces non-ionic surfactants, crucial components in detergents and emulsifiers. Sulfation leads to anionic surfactants like alkyl sulfates, known for their excellent cleaning and foaming properties. These derivative reactions are central to their role as chemical intermediates.

The high carbon-to-hydrogen ratio in the alkyl chain also makes these alcohols relatively stable against oxidation and hydrolysis compared to shorter-chain or unsaturated alcohols. This stability is advantageous in applications requiring long-term performance, such as in industrial lubricants and certain cosmetic formulations. As a supplier committed to quality, NINGBO INNO PHARMCHEM ensures that the Hexadecyl/Octadecyl Alcohol we provide maintains this chemical integrity.

For R&D scientists, understanding these chemical properties allows for informed selection and formulation. Whether designing a new detergent, a stable cosmetic emulsion, or a high-performance lubricant, the specific characteristics of C16/C18 fatty alcohols offer a versatile platform. We encourage researchers and procurement professionals to leverage our expertise and high-quality products to achieve their formulation goals.
