Description
Sodium stearate is an organic compound with the chemical formula C₁₇H₃₅COONa. Sodium stearate appears as a white oily powder, featuring a slippery feel and a fatty odor. Sodium stearate is readily soluble in hot water or hot alcohol.
Advantages
High-temperature tolerance
Sodium stearate exhibits good stability at both room temperature and high temperatures, making it suitable for high-temperature environments such as metal heat treatment and plastic processing.
Stable drug form
In pharmaceutical preparations like glycerin suppositories, the protective film formed by sodium stearate can maintain the stability of the suppositories and prolong their duration of action.
Environmental characteristics
Sodium stearate is free of phosphorus and nitrogen, causes minimal skin irritation, and meets environmental protection requirements, making it suitable for applications in daily chemicals and food additives.
Low irritation
In rectal administration preparations (such as glycerin suppositories), sodium stearate can reduce mucosal friction, alleviate irritation, and enhance user comfort.

Application
As an important chemical raw material, sodium stearate is applied in multiple industrial and consumer product fields:
Daily Chemicals and Detergents
Soap Manufacturing: As the main active ingredient and shaping agent, it imparts excellent detergency and lubricity to soap.
Foam Control: Regulates foam volume during washing and rinsing to improve cleaning efficiency.
Washing Aids: Acts as an emulsifier, dispersant, and thickener to enhance product stability.
Plastics and Polymer Materials Industry
Heat Stabilizer: Eliminates the impact of residual catalysts on color and stability in polyethylene (PE) and polypropylene (PP), and synergizes with materials like zinc soaps to enhance thermal stability.
Lubrication and Demolding: Used in the molding process of thermosetting plastics such as polyolefins, polyester-reinforced plastics, and phenolic resins.
Cosmetics Industry
Emulsification and Thickening: Applied in lotions, creams, shampoos, and other products to improve texture and user experience.
Functional Additives: Provides lubrication and stabilization in shaving gels and transparent adhesives.
Metal Treatment and Anti-Corrosion
Metal Heat Treatment: Participates as an auxiliary agent in key processes of metal processing.
Corrosion Inhibitor: Used in polyethylene packaging films to endow materials with anti-corrosion protection properties.
Packing & Shipping
Sodium stearate is packaged in kraft paper bags, 25KG Per Bag, FCL/LCL shipped by sea.
