USP FCC Food Grade
Lactic acid CH3CH(OH)CO2H is a white, water-soluble solid or clear liquid that is produced both naturally and synthetically. Lactic acid is choral, consisting of two optical isomers. One is known as L-(+)-lactic acid or (S)-lactic acid and the other, its mirror image, is D-(−)-lactic acid or (R)-lactic acid. A mixture of the two in equal amounts is called DL-lactic acid.
Lactic Acid USP Grade
Propanoic acid, 2-hydroxy-. Lactic acid [50-21-5].
Lactic Acid is a mixture of lactic acid (C3H6O3) and lactic acid lactate (C6H10O5) equivalent to a total of not less than 88.0 percent and not more than 92.0 percent, by weight, of C3H6O3. It is obtained by the lactic fermentation of sugars or is prepared synthetically. Lactic Acid obtained by fermentation of sugars is levorotatory, while that prepared synthetically is racemic. [NOTE—Lactic Acid prepared by fermentation becomes dextrorotatory on dilution, which hydrolyzes L-( )-lactic acid lactate to L-(+)-lactic acid.]
Labeling: Label it to indicate whether it is levorotatory or racemic.
Identification: It meets the requirements of the test for Lactate.
Specific rotation: between 0.05 and +0.05 , for racemic Lactic Acid.
Readily carbonizable substances: Rinse a test tube with sulfuric acid, and allow to drain for 10 minutes. Add 5 mL of sulfuric acid to the test tube, carefully overlay it with 5 mL of Lactic Acid, and maintain the tube at a temperature of 15 : no dark color develops at the interface of the two acids within 15 minutes.
Residue on ignition: not more than 3 mg, from a 5-mL portion (0.05%).
Sugars: To 10 mL of hot alkaline cupric tartrate add 5 drops of Lactic Acid: no red precipitate is formed.
Chloride: To 10 mL of a solution (1 in 100) acidified with nitric acid add a few drops of silver nitrate: no opalescence is produced immediately.
Sulfate: To 10 mL of a solution (1 in 100) add 2 drops of hydrochloric acid and 1 mL of barium chloride: no turbidity is produced.
Heavy metals: 0.001%.
Limit of citric, oxalic, phosphoric, or tartaric acid: To 10 mL of a solution (1 in 10) add 40 mL of calcium hydroxide, and boil for 2 minutes: no turbidity is produced.
Assay: To about 2.5 mL of Lactic Acid, accurately weighed in a tared 250-mL flask, add 50.0 mL of 1 N sodium hydroxide, and boil the mixture for 20 minutes. Add phenolphthalein, and titrate the excess alkali in the hot solution with 1 N sulfuric acid. Perform a blank determination.
Each mL of 1 N sodium hydroxide is equivalent to 90.08 mg of C3H6O3.
Lactic Acid FCC Food Grade
α-Hydroxypropionic Acid; 2-Hydroxypropionic Acid
C3H6O3 -- Formula wt 90.08
INS: 270 CAS: L(+)-Lactic Acid [79-33-4]
CAS: DL-Lactic Acid [598-82-3]
Lactic Acid occurs as a colorless or yellow, syrupy liquid consisting of a mixture of lactic acid (C3H6O3) and lactic acid lactate (C6H10O5). It is obtained by the lactic fermentation of
sugars or is prepared synthetically. It is usually available in solutions containing the equivalent of from 50% to 90% lactic acid. It is hygroscopic, and when concentrated by boiling, the acid condenses to form lactic acid lactate, 2-(lactoyloxy)propanoic acid, that on dilution and heating, hydrolyzes to Lactic Acid. It is miscible with water and with alcohol.
Identification: A sample gives positive tests for Lactate.
Assay: Not less than 95.0% and not more than 105.0% of the labeled concentration of C3H6O3.
Chloride: Not more than 0.1%.
Citric, Oxalic, Phosphoric, or Tartaric Acid: Passes test.
Cyanide: Not more than 5 mg/kg.
Iron: Not more than 10 mg/kg.
Lead: Not more than 0.5 mg/kg.
Residue on Ignition: Not more than 0.1%.
Sugars: Passes test.
Sulfate: Not more than 0.25%.

Always seek medical advice after the first aid treatment.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician immediately.
Ingestion: DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Call a physician immediately.
Skin Contact: In case of contact with Lactic Acid, wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Call a physician immediately.
Eye Contact: Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Call a physician immediately.
5. Fire Fighting Measures
Fire: Lactic Acid is not considered to be a fire hazard. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Use means suitable for extinguishing surrounding fire.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Special Information: Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and clothing.
6. Accidental Release Measures
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Wear appropriate personal protective equipment.
Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust. Do not flush caustic residues to the sewer. Carefully pick up solid with minimum of dusting and collect in metal container with covers with disposal. The trace amount of residue of Lactic Acid can be flushed down drain.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids). Do not get in eyes, on skin, on clothing. Wash thoroughly after handling. Store away from acids.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits: This product does not contain any hazardous materials with occupational exposure limits established by the region specific regulatory bodies.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. 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): If the exposure limit is exceeded and engineering controls are not feasible, a full face piece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
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.
