The main use of hexane is as a solvent to extract edible oils from seeds and vegetables such as soybeans, peanuts and corn.

Hexane residues of 21 ppm were discovered in soy meal commonly used to produce soy protein for infant formula, protein bars and vegetarian food products.

Dupont, ADM and Cargill are the largest suppliers of hexane–processed soy protein isolate to “natural food” brands offering soy bars and protein powders.

Almost all “protein bars” on the market today are made with soy protein. Many infant formula products are also made with soy protein, and thousands of vegetarian products (veggie burgers, veggie cheese, “natural” food bars, etc.) are made with soy protein. That soy protein is almost always described as safe and “natural” by the companies using it, however,  much of the “natural” soy protein used in foods today is contaminated with this toxic, explosive chemical solvent.

Hexane is a major air pollutant, off-gassing into the atmosphere.

No information is available on the reproductive or developmental effects of hexane in humans.
