CAS Number: 822-16-2, EINECS EC Number: 212-490-5, HS Code 29181390 or 34039900
Sodium stearate is the sodium salt of stearic acid. This white solid is the most common soap. It is found in many types of solid deodorants, rubbers, latex paints, and inks. It is also a component of some food additives and food flavorings. It is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in the production of various mouth foams.

Sodium stearate CAS 822-16-2
DEFINITION
Sodium Stearate is a compound of sodium with a mixture of solid organic acids obtained from sources of vegetable or animal origin and consists mainly of variable proportions of sodium stearate (C18H35NaO2) and sodium palmitate (C16H31NaO2). The content of stearic acid in the fatty acid fraction is NLT 40.0% of the total content. The sum of stearic acid and palmitic acid in the fatty acid fraction is NLT 90.0% of the total content. Sodium stearate contains small amounts of the sodium salts of other fatty acids.
IDENTIFICATION
A.
Analysis: Heat a small quantity of Sodium Stearate in a crucible over a flame until it fuses. Continue heating the sample until it decomposes with emission of flammable vapors that should burn when ignited. Moisten the residue with water, and test with red litmus paper. The paper must turn blue. Add a small amount of acid to the crucible, and observe the solution effervesce. The solution must impart an intense yellow color to a nonluminous flame.
Acceptance criteria: Meets the requirements
B. The retention times of the major peaks of the Sample solution correspond to those of the Standard solution.
ASSAY
To pass the chromatography test.
Acceptance criteria
Stearic acid: NLT 40.0%
Sum of stearic acid and palmitic acid: NLT 90.0%
Sample solution: Heat 50 mL of alcohol to the same temperature, ±5C, as that attained when the pink endpoint is reached in the titration of the sample specimen. Add 3 drops of phenolphthalein and sufficient 0.020 N sodium hydroxide to produce a faint pink color. Add 2.00 g of Sodium Stearate, and dissolve with the aid of a small amount of heat. No pink color is produced.
Analysis: Titrate the solution with 0.020 N sodium hydroxide until a pink color is produced.
Acceptance criteria: 1.00 to 4.25 mL of 0.020 N sodium hydroxide is required (0.28% 1.2% as stearic acid).
Loss on Drying:
Sample: Tare a beaker containing 1 g of washed sand, previously dried at 105C, add 500 mg of Sodium Stearate, and again weigh.
Analysis: To the Sample add 10 mL of alcohol, and evaporate at 80C to dryness. Dry at 105C for 4 h.
Acceptance criteria: NMT 5.0%
Fats and Fixed Oils, Acid Value:
Sample: 1 g of the fatty acids obtained as follows. Dissolve 25 g of Sodium Stearate in 300 mL of hot water, add 60 mL of 2 N sulfuric acid, and heat the solution, with frequent stirring, until the separated fatty acid layer is clear. Wash the fatty acids with boiling water until they are free from sulfate, collect in a small beaker, and warm on a steam bath until the water has settled and the fatty acids are clear. Allow the acids to cool, pour off the water layer, then melt the acids, filter into a dry beaker while hot, and dry at 105C for 20 min.

Auto Ignition Temperature.: >700F.
Fire Extinguishing Media: Water spray, foam, carbon dioxide or dry chemical.
Unusual Fire & Explosion Hazards: Concentrated dust may present an explosion hazard.
Extinguishing Media Not recommended: Avoid using solid water jet as it may scatter the fire.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment, and emergency procedures: Ventilate area of leak or spill. Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material. Remove all sources of ignition.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment cleanup procedures and Storage: Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g., sand, earth, diatomaceous earth, vermiculite). Vacuum or sweep-up and remove to an approved disposal container. Clean up spills in a manner that does not disperse dust into the air. Use non-sparkling tools and equipment. Reduce airborne dust and prevent scattering by moistening with water.
SECTION 7 - HANDLING AND STORAGE
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Avoid dust formation and control ignition sources. Employ grounding, venting and explosion relief provisions in accord with accepted engineering practices in any process of capable of generating dust and/or static electricity. Ensure proper ventilation. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents and peroxides, strong mineral acids.
SECTION 8 - EXPOSURE CONTROL/PERSONAL PROTECTION
Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region-specific regulatory bodies. There is a blanket recommendation of 10 mg/m3 for inspirable dusts or mists when limits have not otherwise been established.
Respiratory Protection: Work ambient concentrations should be monitored and if airborne concentrations are expected to exceed acceptable levels wear a NIOSH/MSHA approved dust air purifying respirator. When using respirators refer to OSHA’s 29CFR 1910.134.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full-face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
