As a prominent supplier of specialty chemicals, we frequently encounter inquiries about the science behind the ingredients we offer. Today, we delve into the chemical intricacies and application relevance of C12-15 Alkyl Benzoate (CAS 68411-27-8). Understanding its molecular structure, properties, and safety profile is crucial for formulators and procurement specialists seeking to integrate this ester effectively into their products.

Molecular Structure and Chemical Properties

C12-15 Alkyl Benzoate is an ester formed from the reaction of benzoic acid with a mixture of C12-C15 linear and branched alcohols. Its molecular formula is C19H30O2, with a molecular weight of approximately 290.44 g/mol. The 'C12-15' designation indicates that the alkyl chain of the alcohol component typically ranges from twelve to fifteen carbon atoms in length. This specific chain length distribution is key to its desirable physical and chemical properties.

Chemically, it is classified as an ester, characterized by a relatively non-polar nature due to the long alkyl chains. This lipophilicity makes it highly soluble in oils and other non-polar organic solvents, while exhibiting very low solubility in water. Its physical form is typically a clear, colorless to slightly yellowish liquid with a mild, almost imperceptible odor. The moderate viscosity and low volatility contribute to its stability and ease of handling in various formulation processes.

Performance in Formulations: Emollience and Solubilization Explained

The efficacy of C12-15 Alkyl Benzoate in cosmetic and personal care products stems from its amphiphilic nature, though predominantly lipophilic. The ester linkage provides a degree of polarity, while the long alkyl chains impart oil-loving characteristics. This balance allows it to:

  • Act as an Emollient: It spreads easily on the skin, forming a thin film that helps to reduce water loss by creating a barrier on the stratum corneum. This results in a smooth, soft, and conditioned skin feel without the heaviness associated with some other emollients.
  • Function as a Solubilizer: Its lipophilic nature makes it an excellent solvent for other oil-soluble ingredients, including many active ingredients, essential oils, and UV filters. This property is vital for achieving homogeneous dispersions and ensuring the efficacy of formulated products, particularly in sunscreens.
  • Enhance Texture and Spreadability: It contributes to the overall texture of a formulation, improving its spreadability and providing a desirable sensory experience.

Safety and Regulatory Considerations

From a supplier's perspective, safety and regulatory compliance are paramount. C12-15 Alkyl Benzoate has undergone extensive safety assessments by regulatory bodies worldwide. Studies have generally indicated that it is a low-hazard ingredient, showing minimal potential for skin or eye irritation at typical use concentrations. Its large molecular size and low water solubility suggest limited dermal absorption into the bloodstream, further contributing to its favorable safety profile. As with any chemical ingredient, adherence to recommended usage levels and proper handling procedures is advised. Always consult the Safety Data Sheet (SDS) provided by the manufacturer for detailed information.

Sourcing C12-15 Alkyl Benzoate

As a chemical supplier, we understand the importance of consistent quality and reliable supply. When procuring C12-15 Alkyl Benzoate (CAS 68411-27-8), it is essential to partner with manufacturers who can guarantee product purity, adhere to stringent quality control measures, and provide comprehensive documentation. We encourage potential buyers to inquire about specifications, production processes, and regulatory compliance to ensure the ingredient meets their specific formulation needs.
