For chemists, formulators, and product developers, a deep understanding of an ingredient's chemical properties is fundamental to its effective utilization. 2-Hexyl-1-decanol (CAS 2425-77-6), a C16 branched fatty alcohol, possesses a distinct set of physical and chemical characteristics that dictate its behavior and performance in various applications. From its state at room temperature to its solubility and reactivity, these properties are key to unlocking its full potential in cosmetics, industrial chemicals, and beyond.

The physical state of 2-Hexyl-1-decanol at ambient temperatures is a liquid, a direct consequence of its relatively low melting point of approximately -21°C to -15°C. This low melting point is a significant advantage, particularly in cosmetic formulations, as it allows for easy handling and incorporation into products without the need for heating, unlike some higher melting point fatty alcohols. Its boiling point is reported to be around 193-197°C at 33 mmHg, indicating good thermal stability for many processing conditions. The density of 2-Hexyl-1-decanol is approximately 0.836 g/mL at 25°C, which is typical for a long-chain alcohol and influences its behavior in mixtures and emulsions.

In terms of solubility, 2-Hexyl-1-decanol is insoluble in water due to its long, non-polar hydrocarbon chain. However, it is readily soluble in organic solvents such as alcohol, ether, and oils. This solubility profile is critical for its use as a solvent or co-solvent in formulations where water is not the primary medium. Its refractive index, measured at n20/D 1.449, is a characteristic physical property useful for identification and quality control purposes.

Chemically, as a primary alcohol, 2-Hexyl-1-decanol can undergo typical alcohol reactions such as esterification, ethoxylation, and propoxylation. These reactions are fundamental to its use as a precursor in the synthesis of surfactants, esters, and other functional derivatives. The hydroxyl group (-OH) on the terminal carbon atom is the reactive site that allows for these chemical transformations. Understanding these reaction pathways is crucial for chemists aiming to synthesize new compounds or modify the properties of 2-Hexyl-1-decanol for specific applications. For those seeking reliable sources of this chemical, suppliers like NINGBO INNO PHARMCHEM CO.,LTD. provide detailed specifications and technical data to support its appropriate use.

In summary, the chemical properties of 2-Hexyl-1-decanol—its liquid state, low melting point, solubility in organic media, and reactivity as a primary alcohol—collectively define its broad utility. These attributes make it an indispensable ingredient in cosmetic formulations for its emollient and textural benefits, as well as a versatile building block in industrial chemical synthesis.
