Formulated with Propylene Glycol
As compared to the ethylene glycol used in most other brands, propylene glycol is far less toxic and safer for children, pets, and wildlife. Engine Ice Hi-Performance Coolant is also phosphate free (phosphates kill the smallest forms of life in the environment in addition to trees and plants). Propylene glycol comes in both an industrial form and a pharmaceutical form and is used in many consumer products including hair conditioners, cosmetics, and many over-the-counter medications.
Propylene Glycol, the base fluid of Engine Ice Hi-Performance Coolant , meets or exceeds all AS, SAE, Government and Manufacturers standards. It also has NO statutes or health warnings from the Clean Air Act Amendments (CAAA), CERCLA (Superfund), Superfund Amendments & Re-authorization Act (SARA), Occupational Health & Safety Administration (OSHA), American Conference of Governmental Industrial Hygienists (ACGIH), Federal Health & Safety Administration (FHSA).
