Description

7-Octadecenoic Acid is a monounsaturated fatty acid of significant industrial interest. This compound serves as a versatile chemical intermediate and a model compound for studying lipid oxidation and olefin chemistry. It is particularly valuable for manufacturers in the oleochemical, cosmetic, and specialty chemical sectors seeking to develop or modify surfactants, lubricants, and emollients. The material is supplied with a CAS registry number of 14122-42-0.

Application

• Oleochemical Intermediate: A key building block for synthesizing derivatives like esters, amides, and salts used in surfactants and lubricant additives.
• Cosmetic & Personal Care: Used in the formulation of emollients, creams, and lotions, where its fatty acid structure contributes to skin conditioning.
• Research & Development: Acts as a standard or model compound in lipid research, oxidation studies, and analytical method development.
• Specialty Polymers: Can be utilized in the production of polyamides, polyesters, or other polymers requiring specific fatty acid monomers.
• Lubricant Formulation: Serves as a raw material for creating bio-based or synthetic lubricants and metalworking fluids.
• Surfactant Synthesis: A precursor for anionic surfactants (e.g., soaps) and nonionic surfactants through ethoxylation or other reactions.
