Building the key foundations for modern living

Butadiene (C₄H₆) is a colourless, flammable gas with a mild gasoline-like odour. It is an unsaturated hydrocarbon and the simplest conjugated diene, meaning it has two double bonds separated by a single bond.

Diethylene glycol (DEG) is a colourless, practically odourless, and hygroscopic liquid with a sweet taste. It is an organic compound with the formula (HOCH₂CH₂)₂O and is a dimer of ethylene glycol.

Ethoxylates are a class of compounds formed by reacting ethylene oxide with various substrates, such as alcohols, acids, or amines. This process, known as ethoxylation, introduces polyethylene glycol chains to the original molecules, enhancing their solubility and altering their properties.

Ethylene (C₂H₄) is the simplest alkene, a hydrocarbon with a carbon-carbon double bond. It’s a colourless, flammable gas with a faint sweet odour. 

High purity ethylene oxide (C₂H₄O) is a colourless, flammable gas with a faintly sweet odour. It is a highly reactive compound and the simplest epoxide, consisting of a three-membered ring with one oxygen atom and two carbon atoms.

Monoethylene glycol (MEG) is a colourless, odourless, and slightly sweet-tasting liquid. It is a type of glycol, which is a diol with two hydroxyl groups. Its chemical formula is C₂H₆O₂.

Propylene (C₃H₆), also known as propene, is a colourless, flammable gas with a faint petroleum-like odour. It is an unsaturated hydrocarbon with a carbon-carbon double bond. 

A mixture of butenes (iso-butenes and n-butenes) with butane and residual butadiene. Raffinate-1 is colourless gas (liquid under pressure), with a mild, petroleum-like odour.

Styrene (C₈H₈) is a clear, colourless liquid hydrocarbon derived from petroleum and natural gas by-products. It is known for its ability to undergo polymerisation, forming large polymer chains.

Di-propylene glycol (DPG) is a colourless, nearly odourless liquid with a high boiling point and low toxicity. It is a mixture of three isomeric chemical compounds and is known for its excellent solvent properties.

Propylene glycol (industrial grade) is a high-purity, colourless, water-soluble liquid with a medium viscosity and low vapor pressure. It is hygroscopic, meaning it readily absorbs water from the environment. 

Propylene glycol (USP food grade), also known as 1,2-propanediol, is a high-purity form of propylene glycol that meets stringent quality standards set by regulatory agencies such as the US Food and Drug Administration (FDA). It is a colourless, odourless, and slightly sweet-tasting liquid.

Propylene oxide (C₃H₆O) is a colourless, volatile liquid with a faint ether-like odour. It is a highly reactive compound and is considered both toxic and carcinogenic.
