I’ve finally found some liquid colorants that work perfectly in liquid soap. I even tried them out in some new bubble bars and they worked great.
They are water soluble liquid lakes (dye in glycerine) from TKB. Mine were actually from the sale section…the bottle opening was too small to squeeze the colorant out of. Hmmmm…you had to squeeze these pretty hard but they still worked!
They’re also suposed to be good for coloring salts, bathbombs and lotion.
