Applications of Polyglykol 300:
Polyglykol 300 can be used in liquid pharmaceutical preparations such as drops or fillings for gelatin capsules.
Polyglykol 300 can also be used in ointment mixtures for example in combination with Polyglykol 1500.
Polyglykol 300 is listed as active ingredient in ophthalmic demulcents.
Polyglykol 300 is also used in toothpastes where it improves consistency and storage stability.
Polyglykol 300 acts as a moisturizer in antiperspirants, shampoos and liquid soaps, hair styling products and bar soap.
Polyglykol 300 can also be used in bath oils and foam baths to assist the solubilizing action of the active substances for perfume oils.
Polyglykol 300 is used as a humectant in waterborne pigment preparations, and as a solvent and humectant in automatic dish-washing products.
Storage of Polyglykol 300:
PEG 300 is stable for 2 years when stored in the original sealed containers in a cool, dry place.
Polyethylene glycol 300 (PEG 300) is a water-miscible polyether with an average molecular weight of 300 g/mol.
Polyglykol 300 is a clear viscous liquid at room temperature with non-volatile, stable properties.
Polyethylene glycols are widely used in biochemistry, structural biology, and medicine in addition to pharmaceutical and chemical industries.
They serve as solubilizers, excipients, lubricants, and chemical reagents.
Low molecular weight glycols are observed to exhibit antibacterial properties as well.
PEG 300 is found in eye drops as a lubricant to temporarily relieve redness, burning and irritation of the eyes.
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.
Polyglykol 300 is essential to ensure storage in a dry place because liquid PEG are hygroscopic.
Each time the containers are opened, they should be resealed to make them airtight.
Even with sealed laboratory containers it is impossible to prevent atmospheric oxygen and moisture acting on PEG 300 owing to frequent opening.
We therefore recommend that laboratory samples should also not be stored longer than 2 years.
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 300 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.
Applications of Polyglykol 300:
Polyethylene glycol (PEG) is a multipurpose polymer which can be applied in solid, semi-solid and liquid formulations.
Polyglykol 300s broad functional spectrum includes e.g. improvement of API solubility, acting as a lubricant for tablet coating, function as a carrier, and many more.
Our comprehensive portfolio of PEGs comprises diverse polymer sizes of different molecular weights to meet your specific application and needs.

Safety of Polyglykol 300:
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.
PRODUCT DETAILS & INFORMATION:
Polyethylene glycol (PEG) is one of the most commonly used chemical polyethers in manufacturing, medicine and many other applications.
PEG is available in multiple forms for various uses.
The most common way of differentiating between PEGs is by molecular weight.
For example, PEG 300 refers to a polyethylene glycol product with an average weight of 300 daltons.
Acme-Hardesty produces a bio-based PEG 300 product for a wide range of manufacturing processes.
Our product is not derived from raw petroleum materials, making it a more sustainable choice for any environmentally conscious manufacturer.
