Evans coolants contain proprietary blends of glycols, including ethylene glycol. Ethylene glycol, when metabolized by the alcohol dehydrogenase (ADH) enzyme, converts to glycoaldehyde, glycolic acid, oxalic acid, and glyoxylate, all of them toxic. Evans coolants contain a substance that, when mixed with ethylene glycol, inhibits the ADH enzyme from producing the toxic metabolites.
In laboratory testing on rats according to USA EPA GLP regulations, Evans coolants have proven to be non-toxic.
The traditional ethylene glycol warnings that are on Evans coolant products are required for compliance with USA Consumer Product Safety Commission (CPSC) regulations for products sold in the USA. Non-toxicity of Evans coolants with regard to humans has not been verified but laboratory testing on human tissue, under sponsorship by Evans Cooling Systems, Inc., is currently underway. If safety for humans is verified, Evans will petition the USA CPSC for permission to remove the ethylene glycol warnings.
