Antifreeze formulation useful for retarding precipitation of aluminum corrosion products in the cooling systems of internal combustion engines

Antifreeze formulation useful for retarding precipitation of aluminum corrosion products in the cooling systems of internal combustion engines

Precipitation of aluminum corrosion products from phosphate-borate ethylene glycol based antifreeze formulations is retarded by incorporating in the antifreeze a precipitation retarding amount of alkylene diphosphonic acid, e.g., 1-hydroxyethylidene-1,1-diphosphonic acid.
