Lactobionic acid (4-O-β-galactopyranosyl-D-gluconic acid) is a sugar acid. It is a disaccharide formed from gluconic acid and galactose. It can be formed by oxidation of lactose. Lactobionic acid is also used in the cosmetics industry as an antioxidant and in the pharmaceutical industry as an excipient for formulation.

Test solution: Dissolve 10 mg of the substance to be examined in water and dilute to 1 ml with the same solvent.
Reference solution: Dissolve 10 mg of lactobionic acid CRS in water and dilute to 1 ml with the same solvent.
Plate TLC silica gel plate.
Mobile phase concentrated ammonia, ethyl acetate, water, methanol.
Application: 5 μl.
Development: Over 3/4 of the plate.
Detection: Spray 3 times with ammonium molybdate solution and heat in an oven at 110C for 15 min.
Results: The principal spot in the chromatogram obtained with the test solution is similar in position and colour to the principal spot in the chromatogram obtained with the reference solution.

TESTS
Appearance of solution: The solution is clear and not more intensely coloured than reference.
Specific optical rotation: + 23.0 to + 29.0 (anhydrous substance).
Dissolve 1.0 g in 80 ml of water and dilute to 100.0 ml with the same solvent. Allow to stand for 24 h.
Reducing sugars: Maximum 0.2 per cent, calculated as glucose.
Dissolve 5.0 g in 25 ml of water with the aid of gentle heat. Cool and add 20 ml of cupricitric solution and a few glass beads. Heat so that boiling begins after 4 min and maintain boiling for 3 min. Cool rapidly and add 100 ml of a 2.4 per cent V/V solution of glacial acetic acid and 20.0 ml of 0.025 M iodine. With continuous shaking, add 25 ml of a mixture of 6 volumes of hydrochloric acid and 94 volumes of water and, when the precipitate has dissolved, titrate the excess of iodine with 0.05 M sodium thiosulphate using 1 ml of starch solution, added towards the end of the titration, as indicator. Not less than 12.8 ml of 0.05 M sodium thiosulphate is required.
Heavy metals: Maximum 20 ppm.
Water: Maximum 5.0 per cent, determined on 0.50 g.
Total ash: Maximum 0.2 per cent.

ASSAY
Dissolve 0.350 g in 50 ml of carbon dioxide-free water, previously heated to 30C. Immediately titrate with 0.1 M sodium hydroxide and determine the 2 equivalence points potentiometrically.
The first equivalence point (V1) corresponds to the acid form of lactobionic acid and the second equivalence point (V2 - V1) corresponds to the d-lactone form.
1 ml of 0.1 M sodium hydroxide is equivalent to 35.83 mg of C12H22O12.
1 ml of 0.1 M sodium hydroxide is equivalent to 34.03 mg of C12H20O11.
The sum of the 2 results is expressed as a percentage content of lactobionic acid.

EINECS EC Code: 202-538-3

Skin: Rinse with water. Soap may be used. Seek Medical Aid.
Eyes: Wash eyes with plenty of water for at least 15 minutes, lifting lids occasionally. Seek Medical Aid.
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Ingestion: If swallowed, induce vomiting immediately after giving two glasses of water. Never give anything by mouth to an unconscious person.

Flammability of the Product: Non-flammable. However, it can burn at higher temperatures.
Products of Combustion: Oxides of Carbon.
Fire Fighting Media and Instructions: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide. Wear self-contained breathing apparatus for firefighting if necessary.
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.

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.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage:
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and dispose of according to legal requirements.
Large Spill: 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. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. 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.

Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume, or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
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.
