[7] [22] Water-propylene glycol mixtures dyed pink to indicate the mixture is relatively nontoxic are sold under the name of RV or marine antifreeze. Propylene glycol is frequently used as a substitute for ethylene glycol in low toxicity, environmentally friendly automotive antifreeze.
When an aqueous solution of propylene glycol in a cooling or heating system develops a reddish or black color, this indicates that iron in the system is corroding significantly. In the absence of inhibitors, propylene glycol can react with oxygen and metal ions, generating various compounds including organic acids (e.g., formic, oxalic, acetic).
The pink water is typically propylene glycol and water. (The −50 °F (−46 °C) commercial product is 40:60.) Pink dye is used to imply that it is not toxic. Normal antifreeze (an ethylene glycol and water mixture) is colored green or blue to show that it is a toxic chemical. Refrigerator
Propylene glycol – humectant; Propylene glycol alginate – thickener, vegetable gum, stabilizer, emulsifier; Propylene glycol esters of fatty acids – emulsifier; Propylparaben (propyl para-hydroxybenzoate) – preservative; Pumpkin seed oil – a specialty cooking oil, produced in Austria and Slovenia. Doesn't tolerate high temperatures.
Red Dye No. 3 is an artificial food coloring derived from petroleum, commonly added to foods, drinks, supplements and drugs to create an appealing cherry-red or pink hue.
De-icing fluids come in a variety of types, and are typically composed of ethylene glycol (EG) or propylene glycol (PG), along with other ingredients such as thickening agents, surfactants (wetting agents), corrosion inhibitors, colors, and UV-sensitive dye. Propylene glycol-based fluid is more common because it is less toxic than ethylene glycol.
