Description

Fatty Acids C16-18 is a high-purity blend of palmitic (C16) and stearic (C18) acids, representing a fundamental building block for a wide range of industrial formulations. This product matters for its consistent composition and excellent performance as a raw material, intermediate, or functional additive. Industries such as personal care, cosmetics, soaps & detergents, lubricants, and plastics rely on it for its emulsifying, thickening, and conditioning properties.

Application

• Soap & Detergent Manufacturing: A primary raw material for producing high-quality soaps, providing hardness, lather stability, and cleansing properties.
• Personal Care & Cosmetics: Used in creams, lotions, and ointments as an emulsifier, thickener, and opacifying agent.
• Lubricants & Greases: Serves as a key component in metallic soap thickeners for lithium and calcium-based greases.
• Plastics & Polymers: Acts as an internal and external lubricant and release agent in PVC and other polymer processing.
• Candle Making: Used to harden candles and control the melting point and burn characteristics.
• Textile & Leather Processing: Functions as a softening agent and lubricant in fiber and leather treatment.
• Food Grade Applications: When produced to appropriate standards, it can be used as a release agent, binder, and defoaming agent in food processing.
• Chemical Intermediate: A crucial feedstock for producing fatty acid esters, amides, and other derivatives.

Quality Control

Our Fatty Acids C16-18 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for composition, acid value, iodine value, and color. Certificates of Analysis (COA) are provided with every shipment. We can supply grades compliant with relevant industry standards, including food-grade specifications where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong oxidizing agents and heat sources. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize contact with air and moisture.
