I make a similar product. The only difference between the two is carnauba and candellia. I've been making wax products since the 90s including car wax, leather conditioners and wood preservatives This is a liquid wax product below for wood and leather preservation. A similar version that is all food safe ingredients would remove water PEG 6 and polymers. Two versions are white and yellow white being a satin matte finish and yellow being more glossier.
From my SDS
PEG 6 plus Caprylic/Capric Glycerides 10 - 30%
Water 30- 60%
Polyacrylate copolymer .1 - 1%
Food grade ozokerite 5 - 10%
Food grade carnauba leave out for the white version 1-5%
Food grade candellia wax leave out for the white version 1-5%
Food grade microcrystalline wax 7 - 13%
You can get much of the ingredients online.
