Myristoleic acid

Myristoleic acid (CAS 544-64-9) is a naturally occurring monounsaturated fatty acid found in plant seed oils, animal fats, and certain marine sources. It functions as an emulsifier, moisturizing agent, and stabilizer across personal care, food, and pharmaceutical formulations. In cosmetic and skincare formulations, it contributes to emulsion stability and skin conditioning. This makes it a functional component in creams, lotions, and serums targeting moisturization and improved skin barrier function.

Pharmaceutical manufacturers incorporate it as a lipid excipient in topical and semi-solid dosage forms where controlled emulsification is required. It is valued for its consistency and compatibility with various active ingredients. In food-grade applications, it serves as a functional fatty acid in specialty lipid blends and nutritional formulations. It is often used where defined fatty acid profiles are a specific requirement for the final product.

Personal care formulators also use it in hair care products to improve the texture and spreadability of oil-based systems. This helps in creating products that are easier to apply and provide a better sensory experience. The material is typically supplied as a liquid oil at varying purity levels, with high-purity grades available for pharmaceutical and nutraceutical applications. These grades often meet USP or FCC standards depending on the source.

Food-grade and cosmetic-grade specifications are the most commercially prevalent, with purity commonly ranging from 90% to 98%+. The specific purity level is chosen based on the intended use and regulatory requirements. Packaging is generally offered in small laboratory quantities through to bulk drum supply to accommodate both R&D and production-scale procurement. This flexibility ensures that manufacturers can scale their operations efficiently.
