View Full Version : Paint Store Tinting Colors

A few years ago I purchased a full range of 12 oz bottles of "house paint" tinting colors. The carrier for the pigment is listed as ethylene glycol, which is the main ingredient in anti-freeze and I suppose is used because it is soluable in both water-based and oil-based paints. I chose only light-fast, permanent colors. They are VERY concentrated and strong color.

Has anyone used tinting colors such as these mixed with acrylic medium in your paintings?

Nontoxic propylene glycol can be safely used in acrylics to slow their drying, but I have no idea about the toxic ethylene glycol. Try mixing a little of it up and see what happens, but keep the paint away from kids and pets!

Thanks for your reply.

I know that propylene glycol is non-toxic and ethylene glycol definitely IS toxic. But the tinting colors are used in housepaint and the ethylene glycol in housepaint evaporates and, at any rate, is in such small quantities in the wet paint that it would be negligible. I was mostly wondering if anyone had ever used these tinting colors for fine art? Making usable acrylic paint with them would be very much less expensive than tube acrylics. As the old (USA) ad says, "Just a little dab 'il do ya!"

By the way, glycerine is also said to slow acrylic drying time. I read somewhere that too much glycerine and the paint NEVER dries or at least takes a really long time! This is probably because glycerine is very slow to evaporate preventing the paint to polymerize properly.
