Overview
Pentadecanoic acid (CAS 1002-84-2 ), also known as pentadecylic acid, is a saturated C15 fatty acid sourced primarily from dairy fats and certain marine oils. It functions as an emulsifier, surface modifier, and lubricant component across food, cosmetic, and industrial formulations.
In food manufacturing, it is used as a flavoring agent under FEMA 4334 , contributing to dairy and fatty flavor profiles in processed products. Cosmetic formulators incorporate it into creams, lotions, and conditioning products where controlled emulsification is required.
In metalworking and industrial lubricant formulations, it acts as a boundary lubricant and surface-active additive, reducing friction in cutting fluids and specialty greases. It also serves as a reference standard and biomarker material in analytical research.
Supply purity and traceability are procurement priorities for this material. Pentadecanoic acid is supplied as a white to off-white crystalline solid or powder. It is available in research-grade and technical-grade specifications for various industrial needs.
High-purity grades of 98 to 99 percent are commonly stocked for analytical and food flavoring applications. Packaging ranges from small laboratory quantities to bulk orders depending on grade and end-use requirements for the chemical industry.
The material meets rigorous quality benchmarks to ensure consistency in manufacturing. It is essential for developers looking for reliable fatty acid components that provide specific skin-feel modification and chemical stability in diverse environments.
