2-Hexyldecanoic Acid

Product Overview

2-Hexyldecanoic Acid, also known as C16 Guerbet Fatty Acid, represents a specialized class of branched-chain fatty acids engineered for high-performance chemical synthesis. With the CAS registry number 25354-97-6, this compound is distinguished by its unique molecular structure featuring a hexyl branch at the second position of the decanoic acid chain. This specific branching pattern imparts exceptional physical properties, including a low melting point and liquid state at room temperature, which are critical for downstream processing in the fine chemicals and personal care industries.

As a leading global manufacturer, we supply this specialty chemical with stringent quality controls to ensure consistency across batches. The product serves as a vital building block for creating sophisticated ester derivatives that offer superior sensory characteristics compared to linear fatty acid counterparts. Our commitment to excellence ensures that every drum meets the rigorous demands of modern formulation chemistry.

Chemical Properties

The molecular formula C16H32O2 defines the composition of this Guerbet acid, resulting in a molecular weight of approximately 256.42 g/mol. The branched architecture significantly reduces intermolecular forces compared to straight-chain isomers, leading to a density of 0.88 g/cm3 and a refractive index of 1.4460. These physical constants are essential for quality assurance during incoming raw material inspection.

Thermally, the compound exhibits a boiling point range of 165 to 168 degrees Celsius under reduced pressure (2mm Hg), facilitating distillation purification processes. The flash point is recorded at 174 degrees Celsius, indicating standard combustible liquid handling requirements. Chemically, the acid group provides reactivity for esterification, while the hydrocarbon chain offers lipophilicity. It remains stable under normal storage conditions but should be kept away from strong oxidizing agents to prevent degradation.

Industrial Applications

The primary utility of 2-Hexyldecanoic Acid lies in its role as a precursor for synthesizing emollient esters widely used in cosmetic and personal care formulations. Key applications include:

• Synthesis of lightweight esters such as 2-Hexyldecyl Laurate or Myristate for skin care products.
• Production of low-viscosity emollients that provide a dry, non-greasy skin feel.
• Formulation of sun care products where high spreading coefficients are required.
• Use in color cosmetics to improve pigment dispersion and texture.
• Development of hair care agents that enhance shine without weighing down hair.

These derivatives are valued for their oxidative stability and excellent compatibility with various organic solvents and oils. The Guerbet structure ensures that the resulting esters maintain liquid status over a wide temperature range, enhancing product stability in diverse climatic conditions.

Quality Specifications

Our manufacturing process adheres to international standards, ensuring high purity and minimal impurities. Each batch undergoes comprehensive testing using gas chromatography and titration methods. The following table outlines the typical specification profile:

Storage and Handling

To maintain optimal quality, 2-Hexyldecanoic Acid should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Containers must be kept tightly closed when not in use to prevent moisture absorption or contamination. Standard industrial safety protocols apply, including the use of appropriate personal protective equipment during handling. With proper storage, the product maintains its specified properties for an extended shelf life, ensuring reliability for your production schedules.
