Novel Gouache Paint Formulation/ Release Into The Public Domain

I am a chemist and an artist....

Two molar equivalents of citric acid mixed with three molar equivalents of dipropylene glycol with 0.5 ml. glycerol is heated to 175 Deg. C in a convection oven for 15-20 minutes ( at operating temp. range) . The mixture contains 200 mg. of Commasie Blue water-soluble dye. The mixture, upon cooling to ambient temp., yields a very viscous paste which joins with a wet paintbrush to produce a non-streaky paint formulation. This matte paint contains no calcium carbonate ( marble dust) powder. The paint has a unique appearance. I posted this at my website , so the date of release into the public domain is established. I do not want a company patenting the work- I want it in the public domain for artists to use in their work.
