Description

C18-36 Acid CAS NO 135620-17-6 is a high-purity synthetic fatty acid blend, primarily composed of linear, saturated carboxylic acids within the C18 to C36 carbon chain range. This product is valued for its consistent composition and performance as a versatile intermediate in high-value synthesis. It is essential for manufacturers in the personal care, lubricant, and specialty chemical industries seeking reliable raw materials for esterification and other derivatization processes.

Application

• Personal Care & Cosmetics: A key raw material for producing high-melting-point emollient esters, waxes, and consistency factors in creams, sticks, and balms.
• Lubricants & Greases: Used in the synthesis of complex metal soap thickeners (e.g., lithium, calcium soaps) and as a precursor for specialty ester-based lubricants.
• Polymer & Plastic Additives: Serves as an internal or external lubricant and processing aid in plastics manufacturing, and as a monomer for polyamide resins.
• Coatings & Inks: Employed in the production of alkyd resins and other coating polymers to modify flexibility, drying time, and gloss.
• Textile & Leather Auxiliaries: Acts as a softening agent and waterproofing component in finishes and treatments.
• Food Contact Materials: Suitable for manufacturing additives and components for food packaging and processing equipment where regulatory compliance is required.

Quality Control

Our C18-36 Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) detailing key parameters such as acid value, saponification value, iodine value, and solidification point are provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
