Ultrafine Zinc Stearate Emulsion: Colloidal Lubrication and Release at the Nanoscale zinc stearate tds
1. Chemical Composition and Colloidal Framework 1.1 Molecular Architecture of Zinc Stearate (Ultrafine zinc stearate emulsion) Zinc stearate is a metallic soap developed by the reaction of stearic acid– a long-chain saturated fatty acid (C ₁₇ H ₃₅ COOH)– with zinc ions, leading to the compound Zn(C ₁₇ H ₃₅ COO)₂. Its molecular structure contains
