Hazard information
Regulatory Information
Chemical: Octadecanoic acid, calcium salt
Octadecanoic acid, calcium salt (2:1) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Octadecanoic acid, calcium salt (2:1) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Status: Active Update: 06-04-2023 https://echa.europa.eu/registration-dossier/-/registered-dossier/18930
Octadecanoic acid, calcium salt: Does not have an individual approval but may be used under an appropriate group standard
Other Safety InformationIMAP assessments - Octadecanoic acid, calcium salt: Human health tier I assessment
Fire HazardsCombustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
Hazards SummaryIn the GRAS (generally recognized as safe) database of the US Food and Drug Administration (FDA); [ChemIDplus] Has similar properties to other stearates; Low toxicity; Explosive dust-air mixtures can form; [CHEMINFO] See STEARATES.
FDA Requirements
Calcium stearate is a food additive permitted for direct addition to food for human consumption, as long as 1) the quantity of the substance added to food does not exceed the amount reasonably required to accomplish its intended physical, nutritive, or other technical effect in food, and 2) any substance intended for use in or on food is of appropriate food grade and is prepared and handled as a food ingredient.
Substance added directly to human food affirmed as generally recognized as safe (GRAS).
Calcium stearate is an indirect food additive for use as a component of resinous and polymeric coatings.
Feed-grade calciium stearate is a food additive permitted in feed and drinking water of animals.
EPA Safer ChemicalChemical: Calcium stearate
FIFRA Requirements
Residues of calcium stearate are exempted from the requirement of a tolerance when used as a stabilizer, component of plastic animal tags in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to animals.
Residues of calcium stearate are exempted from the requirement of a tolerance when used as a solid diluent, carrier, in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.
Chemical DangersDecomposes on burning. This produces irritating fumes.
Physical DangersDust explosion possible if in powder or granular form, mixed with air.
Hazard Classes and CategoriesEye Irrit. 2 (14.1%)
Safety & protection
Fire FightingUse water spray, powder, alcohol-resistant foam, carbon dioxide.
First Aid Measures
Fresh air, rest.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth.
Disposal Methods
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Spillage DisposalPersonal protection: particulate filter respirator adapted to the airborne concentration of the substance. Vacuum spilled material with specialist equipment.
Eye PreventionWear safety goggles.
Fire PreventionNO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).
Inhalation RiskA nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
Allowable Tolerances
Residues of calcium stearate are exempted from the requirement of a tolerance when used as a stabilizer, component of plastic animal tags in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to animals.
Residues of calcium stearate are exempted from the requirement of a tolerance when used as a solid diluent, carrier, in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest.
Ingestion PreventionDo not eat, drink, or smoke during work.
Inhalation PreventionUse local exhaust or breathing protection.
