About Polyethylene Glycol

Polyethylene Glycol, commonly known as PEG (Polyether Polyols), is a versatile polymer of ethylene oxide. Within Pharmaceutical, Beauty & Personal Care, & Industrial Chemicals hierarchies, PEG series is defined by its molecular weight, which dictates its physical form—ranging from clear, viscous liquids (PEG 200–600) t...

Toxicological Note
Low oral and dermal toxicity; non-irritating under standard use

Pharmaceuticals: Versatile Drug Delivery

Liquids (200-600): Solvent carriers in liquid-fill capsules and oral solutions Solids (1000-6000): Water-soluble bases for ointments and suppositories. PEG 4000/6000 are essential as binders and lubricants in tablet compression.

Beauty & Personal Care: Moisture & Texture

Humectants, drawing moisture into the skin. In shampoos and lotions, they serve as viscosity modifiers and solubilisers for fragrances and essential oils. High-weight PEGs provide a creamy "spreadability" to lipsticks and solid balms

Industrial: Lubricants & Antistatic Agents

In the textile industry-Lubricants for fibers during spinning In the rubber and plastics industries-Functions as effective mold release agents Synthetic polymers-plasticisers in adhesives and as antistatic agents

Additional Features

Solvent Power: Compatible with polar and semi-polar compounds Hydrophilic Carrier: Enhances bioavailability in drug systems Non-Volatile: Thermally stable in extended processing environments Blendable: Mixes well with other PEG grades or polyols Low Toxicity & Biocompatibility: Safe for skin-contact applications Paints & Coatings: Flow modifier, viscosity reducer

Storage Temperature

Store at 15–30°C

Storage Environment

Dry, well-ventilated; avoid prolonged heat exposure

Storage Protection

Protect from moisture ingress

Storage Stability

Highly stable but hygroscopic. Liquid grades may undergo slow oxidative degradation if exposed to heat and air.

Storage Section

Store in a cool, dry place. Liquid grades should be kept in stainless steel or HDPE containers, preferably under a Nitrogen Blanket for long-term storage.

Shipping

Non-hazardous for transport. Liquids available in 230kg drums or IBCs; Solids (4000/6000) available in 25kg bags or flakes.
