Patent abstract
An antifreeze composition and method of use provides safety and protection for potable water systems in RVs, vacation homes, swimming pools and raw water cooled marine engines against freeze damage. The antifreeze composition includes propylene glycol, a sorbitol surfactant having a high Hydrophilic Lipophilic Balance (HLB) number and water. The preferred sorbitol surfactant consists of food grade polyoxyethylene (20) sorbitan monooleate. By directing the antifreeze composition into these water systems, freeze damage is prevented even when the temperature drops to extremely low levels.
