General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Heptane is an environmentally preferable solvent and greener alternative to hexane and thus has been enhanced for "Safer Solvents and Auxiliaries". Click here for more information.
Heptane is a linear hydrocarbon that is considered as a greener alternative to the more toxic hexane.

Application

Greener alternatives to Hexane.

Features and Benefits

Greener alternative for hexane
