Tetradecane

Tetradecane (CAS 629-59-4) is a straight-chain saturated hydrocarbon with the molecular formula C14H30, commercially available under trade names including Linpar 14, N 14, and TS 4. It carries no assigned E-code and is catalogued under EC number 211-096-0. It belongs to the alkane C14 fraction of the linear paraffin series.

In personal care formulations, tetradecane functions as an emulsion stabiliser and hair conditioner by reducing interfacial tension between oil and water phases, improving droplet stability without contributing polarity. In metalworking and lubricant applications, its linear chain geometry provides a consistent, low-viscosity carrier that reduces friction between metal surfaces under moderate load conditions.

Tetradecane is supplied as a colourless liquid in technical and cosmetic grades, with REACH registration applicable for EU market supply. Procurement quantities typically range from drum to isotank formats. Buyers should confirm grade specification against intended application, particularly where cosmetic or food-contact compliance is required.
