Description

Carboxylic Acids, C16-18 And C18-Branched is a high-purity blend of long-chain fatty acids, primarily palmitic, stearic, and branched-chain isomers. This product is valued for its excellent chemical stability and versatility as a key intermediate in industrial synthesis. It is essential for manufacturers in the personal care, lubricant, and polymer industries seeking consistent raw material performance.

Application

• Soap & Detergent Manufacturing: Acts as a primary raw material for producing high-quality metallic soaps (e.g., calcium, zinc stearates) and surfactants.
• Personal Care & Cosmetics: Used in the formulation of creams, lotions, and ointments as an emollient and viscosity modifier.
• Polymer & Plastic Additives: Serves as an internal and external lubricant, acid scavenger, and slip agent in PVC and other polymer processing.
• Lubricants & Greases: A crucial component in the synthesis of synthetic esters and lithium complex greases, providing excellent thermal stability and lubricity.
• Textile & Leather Auxiliaries: Employed as a softening agent and water repellent in fabric and leather treatment processes.
• Candle & Wax Blending: Used to modify the melting point, hardness, and burn characteristics of candles and industrial wax blends.
