PEG (Polyethylene Glycol) Supplier South Africa

What Is Polyethylene Glycol?

Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water, available across a continuous range of molecular weights — from short-chain liquids (PEG-90, PEG-200, PEG-400) to high-molecular-weight waxy solids (PEG-1500, PEG-4000). The number following PEG indicates average molecular weight in daltons. All grades are non-ionic, water-soluble, and non-volatile, but their physical state, viscosity, and specific application suitability vary with molecular weight.

Formulation Functions by Grade

Low-MW liquid PEGs (PEG-90 to PEG-600) are used as humectants, solubilisers, and coupling agents in liquid detergents, personal care products, and pharmaceutical solutions. Mid-range PEGs (PEG-1000, PEG-1500) function as thickeners and consistency modifiers. High-MW solid PEGs (PEG-3350, PEG-4000) are tablet binders, suppository bases, and lubricants in pharmaceutical manufacturing, and also solid binders in compressed powder cleaning tablets and dishwash detergent blocks.

Supply and Grade Selection

Terracore Chemicals stocks liquid and solid PEG grades from PEG-90 through to PEG-4000, in technical, cosmetic, and pharmaceutical (USP) grades. We advise formulators on grade selection for specific functions and can supply mixed-grade quantities for product development. Packaging is available in drums (liquid grades) and 25 kg bags (solid grades).
