SDS MSDS Sheet of Macrogols Manufacturers
Pure BP Grade
Action and use: Non-ionic surfactant.
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.
A. It complies with the test for viscosity (see Tests).
B. To 1 g in a test-tube add 0.5 ml of sulphuric 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 R and shake. The liquid phase becomes blue.
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 in Table 1444.-1.
For macrogols having 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: See Table 1444.-2.
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 expression: [56.1x(n2-n1)]m
For macrogols having 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 the 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.
competent authority may impose a limit of not more than 15 ppm.
Ethylene glycol and diethylene glycol: LimitıMaximum 0.4 per cent, calculated as the sum of the contents of ethylene glycol and diethylene glycol.
Ethylene oxide and dioxan: Maximum 1 ppm of ethylene oxide and 10 ppm of dioxan.
Heavy metals: Maximum 20 ppm.
Water: Maximum 2.0 per cent for macrogol with a relative molecular mass not greater than 1000 and maximum 1.0 per cent for macrogol with a relative molecular mass greater than 1000, determined on 2.00 g.
Sulphated ash: Maximum 0.2 per cent, determined on 1.0 g.
In an airtight container .
The label states:
the type of macrogol;
the content of formaldehyde.

Percent: 95-100% (Dilution is with water, as required)
Section 4 - First Aid Measures
Always consult a physician after the first aid is given.
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Do NOT allow victim to rub or keep eyes closed.
Skin: Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
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.
Notes to Physician: Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
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 in order to prevent pressure build-up, auto-ignition or explosion.
Section 6 - Accidental Release Measures
Spills/Leaks: Use proper personal protective equipment. Restrict unprotected personnel from the area. Remove all ignition sources and ventilate area. Contain the spill with sand or other inert absorbent material, neutralize with sodium bicarbonate or calcium hydroxide, and deposit in a sealed bag or container. Use water spray to dilute spill to a non-flammable mixture. Avoid runoff into storm sewers and ditches which lead to waterways. Wash area with soap and water. Use water spray to disperse the gas/vapor.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container of Macrogols tightly closed. Avoid ingestion and inhalation. Do not allow contact with heat. Do not breathe vapors or spray mist.
Storage: Store Macrogols in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from heat and incompatible materials.
Section 8 - Exposure Controls, Personal Protection
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. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.
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. 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.
