Fatty acids, C16-18

Fatty acids, C16-18 (CAS 67701-03-5) is a mixed-chain fatty acid blend derived from vegetable or animal fats, combining palmitic and stearic acid fractions in commercially relevant ratios. It functions as a lubricant and surface modifier.

Sold under trade designations such as Emersol stearic acid 120 and Emersol stearic acid 132, it acts as a rheology modifier across a broad range of industrial and consumer product manufacturing sectors globally.

In personal care, it acts as an emulsifier and consistency agent in creams, lotions, and bar soaps, contributing to texture and skin feel without requiring additional thickeners or stabilizers in the formula.

Rubber and tire compounders use it as an activator and internal lubricant during vulcanization, improving processing efficiency and compound flow. This ensures high-quality output during the manufacturing of rubber goods.

Plastics processors incorporate it as a mold release agent and processing aid in PVC and polyolefin systems, reducing die buildup and improving surface finish. It is essential for maintaining high production speeds.

In coatings and adhesives, it modifies surface tension and improves substrate wetting, directly affecting adhesion performance and film formation. This makes it a versatile additive for various industrial coating applications.

Supplied as flakes, pastilles, or a solid waxy mass, with liquid form available for bulk industrial supply. Standard grades include technical, food-grade, and cosmetic-grade specifications for diverse industrial needs.

Purity levels are typically defined by iodine value and acid value. Buyers should confirm the palmitic-to-stearic ratio, as this varies by grade and affects performance in specific end-use formulations and products.
