Potassium palmitate

Potassium palmitate (CAS 2624-31-9), also recognized under E-470(i) in food-grade contexts, is the potassium salt of palmitic acid used commercially as a surfactant and soap base. It functions across cleaning, foam control, and emulsification applications in both industrial and consumer-facing formulations. In personal care, it acts as the primary saponification product in soap manufacturing.

This material contributes to lather structure and skin feel in bar and liquid soaps. Food-grade material compliant with the E number is used as an emulsifier and anti-caking agent in processed foods. It is frequently found in bakery products and confectionery coatings. Textile and leather processors use it as a scouring and degreasing agent to remove natural oils and residues from fiber and hide surfaces.

During wet processing, it ensures clean surfaces for further treatment. Paper manufacturers incorporate it into sizing and coating formulations to improve water resistance and surface uniformity across the web. Potassium palmitate is supplied as a powder, flakes, or paste depending on concentration and intended processing method. Food-grade material is available to specific regulatory standards for safety.

Technical-grade product is supplied for industrial cleaning and textile applications. Purity levels and active content vary by grade, and buyers should confirm specification sheets against their requirements.
