Preserving Archaeological Specimens of Polyglykol 1000:
Archaeologists and other scientists who dig in old bogs and who probe the depths of the oceans frequently find wood artifacts they want to preserve.
Usually these artifacts are badly deteriorated by marine insects or various bacteria and decay organisms that dissolve much of the carbohydrate portion of the wood and leave mainly the resistant lignin.
When these partially decomposed wooden artifacts are exposed to drying they break down into fragments or become dust.
If not too badly disintegrated, however, they can be preserved by treating with Polyglykol 1000.
Most of, these artifacts can be successfully treated by soaking 3 to 4 weeks in a 50 percent Polyglykol solution at ambient temperature.
The Polyglykol readily diffuses into the partially deteriorated, watersoaked fine structure of the wood, supports Polyglykol 1000, and keeps Polyglykol 1000 intact during the drying process.
For badly deteriorated artifacts Polyglykol 1000 may be necessary to start with a less concentrated Polyglykol solution and to use a polyethylene glycol polymer of higher molecular weight, such as Polyglykol 1540 to even Polyglykol 4000.
For extreme deterioration Polyglykol 1000 may be best to start with a liquid, like Polyglykol 400, and then gradually increase to the higher molecular weights until the desired result is attained.
Properties of Polyglykol 1000:
The physical and chemical properties of polyethylene glycols are mainly determined by the two hydroxyl end groups, the ether groups as well as the molecular weight.
Polyglykol 1000 is a yellowish wax-like solid at room temperature.
Polyglykol 1000 is soluble in water and polar organic solvents like acetone or methanol.
Polyglykol 1000 is insoluble in pure hydrocarbons.
Polyglykol 1000 shows typical chemical reactions of alcohols/diols and a very low evaporation rate.
The solidification point of Polyglykol 1000 is about 38 °C.
Storage of Polyglykol 1000:
Polyglykol 1000 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 polyethylene lined 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.
Polyglykol 1000 solidifies when stored in a cool place and must be melted before use.
This is best carried out in heating chambers, but the outside temperature should not exceed about 60°C.
This must also be ensured when electrical drum heaters are used.
Electrical immersion heaters are no suitable for melting owing to the high thermal stress occurring.
Safety of Polyglykol 1000:
Polyglykol 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 Polyglykol is important.
When administered orally and cutaneously they are to be rated as non-toxic.
The vapour pressure of Polyglykol is so low that inhalation of relevant amounts is impossible.
Because of their good physiological tolerability Polyglykol were first included in the US pharmacopoeia already in 1950.
Since then they have been listed in numerous pharmacopoeias.
The tolerability of Polyglykol in animals improves as the degree of polymerization rises.
Polyglykol have no toxic or irritant effect on the skin.
Because of low toxicity Polyglykol 1000 was not possible to establish an exact LD50 resulting from skin penetration.
Ecological Data:
The behavior of Polyglykol 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 Polyglykol decreases with increasing molar mass.
Polyglykol 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 Polyglykol.
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 Polyglykol to be disposed of waste can be taken, in accordance with the local regulations, to a special waste incineration plant.
None of Polyglykol, in concentrations up to 10,000 mg/l water, demonstrates an acute harmful effect on fish or bacteria.
Polyglykol with molar masses of 200 to 1500 have good biodegradability.
Polyglykol 1000 is therefore possible to take them to a biological sewage treatment plant after consulting the operator provided the water and waste regulations permit.
