> Applications
Calcium Stearate is evaluated by formulation, excipient-screening, powder-processing, tableting, plastics, rubber, cosmetic, and process-development teams that need a hydrophobic metal stearate or fatty-acid salt. PubChem compound record CID 15324, accessed in 2026 (n=73 synonyms), lists Calcium Stearate as C36H70CaO4 with molecular weight 607.0 g/mol and InChIKey CJZGTCYPCWQAJB-UHFFFAOYSA-L. Buyers should confirm grade, fatty-acid profile, particle size, impurity limits, documentation, and intended market requirements before order confirmation.
Lubricant and processing additive identity
Calcium Stearate is commonly considered where a low-use-level lubricant, anti-adherent, release aid, or anti-caking material is needed for powder blends and process trials. Typical specification discussions include appearance, identification, free fatty acid, loss on drying, calcium content or related assay items, metals, and particle size distribution.
Formulation and process fit
Project teams may compare Calcium Stearate with magnesium stearate, silicon dioxide, talc, or other flow and lubrication aids depending on blend behavior, tableting route, release needs, and target product category.
