Zinc stearate
CAS No.557-05-1
Alias: Afco-chem ZNS;Zinc Stearate, Zno;stavinorzn-e;stearatedezinc;Synpro 8;Synpro stearate;Talculin Z;talculinz
Molecular formula: C36H70O4Zn
Relative molecular mass: 632.33
Structural formula:
1. Performance and use:
Zinc stearate is white light fine powder. Formula is ZN (C17H35COO) 2, molecular structure is RCOOZnOOCR (R is alkyl group of industry stearate), it is combustible, specific gravity is 1.095, ignition point is 900℃, density is 1.095, melting point is 130℃, it has creamy feel. It is insoluble in water, alcohol, ether, soluble in hot ethanol, turpentine, benzene and other organic solvents and acids.
Zinc stearate can be used as rubber products soften lubricants, textiles lighting agent, PVC stabilizers.
Zinc stearate can be used as stabilizer in polyvinyl chloride plastics, rubber softener.
Zinc stearate can be used in the pharmaceutical industry, preparation of solidified oil and lubricants, it can be also used as paint drying agent. Non-toxic products for PVC and rubber processing, the synergy of calcium stearate and barium stearate can effectively improve PVC and rubber for light and heat stability, PVC processing amount is usually <1; it can be used for touch agent of rubber products, it can also be used as polymeric additive of PP, PE, PS, EPS and pencil manufacturing, it is generally used in the amount of 1 to 3 parts.
Used in Rubber, Plastic, Poyester, Abbrasive, Coating, Printing Inks and PVC Industry.
zinc stearate is used in cosmetic formulations to increase adhesive properties. It is also used as a coloring agent. This is a mixture of the zinc salts of stearic and palmitic acids.

3. Packaging and storage
Zinc stearate solid is packaged in plastic woven bags lined with polyethylene bags, with a net weight of 25kg per bag, which can also be determined according to user needs.
Store in a cool and ventilated place indoors, avoid moisture and exposure, and the storage period is twelve months.
5. Safety protection
Zinc stearate is used in oral and topical pharmaceutical formulations, and is generally regarded as a nontoxic and nonirritant excipient. However, following inhalation, it has been associated with fatal pneumonitis, particularly in infants. As a result, zinc stearate has now been removed from baby dusting powders.
