Macrogols BP Ph Eur Grade Specifications:
Action and use: Non-ionic surfactant.

DEFINITION
Mixtures of polymers with the general formula H-[OCH2-CH2]n-OH where n represents the average number of oxyethylene groups. The type of macrogol is defined by a number that indicates the average relative molecular mass. A suitable stabiliser may be added.

IDENTIFICATION
A. Viscosity.
B. To 1 g in a test-tube add 0.5 mL of sulfuric acid, close the test-tube with a stopper fitted with a bent delivery tube and heat until white fumes are evolved. Collect the fumes via the delivery tube into 1 mL of ;mercuric chloride solution. An abundant, white, crystalline precipitate is formed.
C. To 0.1 g add 0.1 g of potassium thiocyanate and 0.1 g of cobalt nitrate and mix thoroughly with a glass rod. Add 5 mL of methylene chloride and shake. The liquid phase becomes blue.

TESTS
Appearance of solution: The solution is clear and not more intensely coloured than reference solution.
Dissolve 12.5 g in water and dilute to 50 mL with the same solvent.
Acidity or alkalinity: Dissolve 5.0 g in 50 mL of carbon dioxide-free water and add 0.15 mL of bromothymol blue solution. The solution is yellow or green. Not more than 0.1 mL of 0.1 M sodium hydroxide is required to change the colour of the indicator to blue.
Viscosity: The viscosity is calculated using a density given ----to meet the requirement.
For macrogols with a relative molecular mass greater than 400, determine the viscosity on a 50 per cent m/m solution of the substance to be examined.
Freezing point: To meet the requirement.
Hydroxyl value: Introduce m g (see Table 1444.-3) into a dry conical flask fitted with a reflux condenser. Add 25.0 mL of phthalic anhydride solution, swirl to dissolve and boil under a reflux condenser on a hot plate for 60 min. Allow to cool. Rinse the condenser first with 25 mL of pyridine and then with 25 mL of water, add 1.5 mL of phenolphthalein solution and titrate with 1 M sodium hydroxide until a faint pink colour is obtained (n1 mL). Carry out a blank test (n2 mL). Calculate the hydroxyl value using the following expression:

For macrogols with a relative molecular mass greater than 1000, if the water content is more than 0.5 per cent, dry a sample of suitable mass at 100-105C for 2 h and carry out the determination of the hydroxyl value on dried sample.

Reducing substances: Dissolve 1 g in 1 mL of a 10 g/L solution of resorcinol and warm gently if necessary. Add 2 mL of hydrochloric acid. After 5 min the solution is not more intensely coloured than reference solution.
Formaldehyde: Maximum 30 ppm.
Ethylene glycol and diethylene glycol: to pass the test.
Water: Maximum 2.0 per cent for macrogols with a relative molecular mass not greater than 1000 and maximum 1.0 per cent for macrogols with a relative molecular mass greater than 1000, determined on 2.00 g.
Sulfated ash: Maximum 0.2 per cent, determined on 1.0 g.

Inhalation: Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Flammability: Combustible but not flammable.
Extinguishing Media: Use Water, dry chemical powder, alcohol foam, water spray or fog. Cool containing vessels with water jet to prevent pressure build-up, auto-ignition, or explosion.
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.

Personal precautions, protective equipment, and emergency procedures: 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.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Use proper personal protective equipment. Restrict unprotected personnel from the area. Remove all ignition sources and ventilate area. Do not inhale dust, vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Neutralize with sodium bicarbonate or calcium hydroxide, and deposit in a sealed bag or container. Use a shovel to put the material into a convenient waste disposal container. Use water spray to dilute spill to a non-flammable mixture.

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. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
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 inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents.

Airborne Exposure Limits: Not available.
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 (NIOSH type N95 or better filters) may be worn. 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 positive-pressure, air-supplied respirator.
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.
