Dipropylene glycol is a mixture of three isomeric chemical compounds, 4-oxa-2,6-heptandiol, 2-(2-hydroxy-propoxy)-propan-1-ol, and 2-(2-hydroxy-1-methyl-ethoxy)-propan-1-ol. It is a colorless, nearly odorless liquid with a high boiling point and low toxicity.[2][3]

Uses

Dipropylene glycol finds many uses as a plasticizer, an intermediate in industrial chemical reactions, as a polymerization initiator or monomer, and as a solvent. Its low toxicity and solvent properties make it an ideal additive for perfumes and skin and hair care products. It is also a common ingredient in commercial fog fluid, used in entertainment industry fog machines.[2][3][4]

gollark: So you're trying to detect... when someone *stops* pressing the buttons, I assume?

gollark: No, it's undefined behavior as far as I know. At least it is in regular C.

gollark: Which could lead to undefined behavior, and thus horror.

gollark: One problem I can see is that you're not initializing `total`.

gollark: oh Cthulhu the lack of indentationAnyway, what's the problem?
