Propylene Glycol?

Figured this was the best choice to place this question. Although it's ultimately about roof cleaning, it's about a product some of you fellas may or may not use.

What will propylene glycol to if mixed with chlorine? Wondering if it will add extra punch to chlorine as it does to hydroxide mixes. Wanted to ask before trying it, considering I don't know the reaction it will create.

Parroting what Mike has just said, its a great additive for a downstreamable stripper mix.

Before you mix any chemical compounds together, download this NOAA chemical reactivity worksheet.


When I ran sodium hypochlorite and polypropolene glycol, here is what came back:

- Forms very unstable explosive metallic compounds
- Reaction proceeds with explosive violence and/or forms explosive products
- Spontaneous ignition of reactants or products due to reaction heat
- Exothermic reaction. May generate heat and/or cause pressurization
- Combination liberates gaseous products, at least one of which is toxic. May cause pressurization

You can see why having that worksheet installed on your desktop can come in handy.
