Safety
PEG are non-toxic and physiologically safe so no special safety precautions need to be taken when handling them. For many applications, particularly in pharmaceuticals, cosmetics and foodstuffs packging, the physiological safety of PEG is important. When administered orally and cutaneously they are to be rated as non-toxic. The vapour pressure of PEG is so low that inhalation of relevant amounts is impossible. Because of their good physiological tolerability PEG were first included in the US pharmacopoeia already in 1950. Since then they have been listed in numerous pharmacopoeias. The tolerability of PEG in animals improves as the degree of polymerization rises. PEG have no toxic or irritant effect on the skin. Because of low toxicity it was not possible to establish an exact LD50 resulting from skin penetration.

Ecological Data
The behaviour of PEG in effluent is a matter of crucial importance, e.g. in their industrial use in the textile sector and in metal processing. The rate of biodegradation of PEG decreases with increasing molar mass. PEG up to molar mass 1500 are regarded as readily biodegrad able (Zahn-Wellens test). The microbiological degradation of other substances is not inhibited by the presence of PEG. The toxic inhibition limit for bacteria in the fermentation tube test is 5000 mg/l. Investigations within our own labs have shown that even in concentrations of 10000 mg/kg (1%) polyethylene glycols have no adverse effect on fish (crucian carp). Polyethylene glycols in concentration up to 10000 mg/l exhibit no harmful effect of any kind towards daphnia and protozoa. The German water hazard class is WGK 1.

Waste Disposal
Any PEG to be disposed of waste can be taken, in accordance with the local regulations, to a special waste incineration plant. None of PEG, in concentrations up to 10,000 mg/l water, demonstrates an acute harmful effect on fish or bacteria.

Applications
Polyglykol 1500 FL is recommended for the use in ointment mixtures, for example in combination with Polyglykol 300.

It is also used in toothpastes where it improves consistency and storage stability. It acts as a moisturizer in antiperspirants, shampoos and liquid soaps, hair styling products and bar soap.

Polyglykol 1500 FL can also be used in bath oils and foam baths to assist the solubilizing action of the active substances for perfume oils.

Storage
PEG 1500 FL is stable for 2 years when stored in the original sealed containers in a cool, dry place.

Furthermore the containers should not be exposed to direct sun light. Ambient temperatures for long term storage are preferably between 10°C and 25°C and between 0°C and 30°C as maximum. Storage at higher temperatures is possible only for a short time and should be kept below the solidification point of the products.

The most suitable material for storage tanks is stainless steel, pure aluminium, rubber-or polyethylenelined containers and storage tanks made from glass-fibre-reinforced polyester (GRP). The tank should be ventilated by means of a silica gel dryer. Conventional steel tanks are of limited suitability because after prolonged storage the product may become discoloured owing to traces of iron.

The recommended method of storing PEG 1500 FL is in stainless steel or aluminium containers fitted with an external, heating coil. The storage temperature should not exceed 70°C, and it is advisable to thoroughly mix the contents of the storage container with a dry nitrogen stream or a circulating pump.
