Description

Fatty Acids, Cottonseed-Oil, Me Esters CAS NO 61788-60-1 are a specific class of methyl esters derived from the fatty acid profile of cottonseed oil. This product serves as a versatile and consistent chemical intermediate, offering a defined composition for precise formulation control. It is primarily required by manufacturers in the oleochemical, surfactant, and lubricant industries for applications demanding a renewable, plant-derived feedstock.

Application

• As a key intermediate in the production of fatty alcohols via hydrogenation.
• In the synthesis of biodiesel and other bio-based fuels.
• As a raw material for manufacturing surfactants, emulsifiers, and detergents.
• In the formulation of lubricants, plasticizers, and metalworking fluids.
• As a reactant for producing alkanolamides and other specialty chemicals.
• In cosmetic and personal care formulations as an emollient or conditioning agent.

Quality Control

Our Fatty Acids, Cottonseed-Oil, Me Esters are produced under a rigorous quality management system. Each batch is analyzed to ensure it meets defined specifications for composition, purity, and physical properties. A comprehensive Certificate of Analysis (COA) detailing ester content, acid value, iodine value, and other critical parameters is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and oxidizing agents. Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 15-25°C.
