not chemically alter the ethanol molecule. Rather, the ethanol is mixed with other chemicals to form an undrinkable solution.
Different additives are used to make it difficult to use distillation or other simple processes to reverse the denaturation. Methanol is commonly used both because its boiling point is close to that of ethanol and because it is toxic. In many countries, it is also required that denatured alcohol be dyed blue or purple with an aniline dye.
Grain alcohol itself might be very difficult or even impossible to obtain in some places due to law surrounding alcohol possession/ selling.
Sodium Thiosulfate (crystals)
(Dutch- natrium thiosulfaat German-Natriumthiosulfat French -thiosulfate de sodium Spanish-tiosulfato de sodio )
Sodium thiosulfate (Na2S2O3), also spelled sodium thiosulphate, is a colorless crystalline compound that is more familiar as the pentahydrate, Na2S2O3·5H2O, an efflorescent, monoclinic crystalline substance also called sodium hyposulfite or “hypo.”
Gum Sandarac (or Sandarac Gum)
(Dutch-Sanderac hars German-Sandarak Kaugummi French -la gomme de sandaraque Spanish-goma sandáraca )
Sandarac (or sandarach) is a resin obtained from the small cypress-like tree Tetraclinis articulata. The tree is native to the northwest of Africa with a notable presence in the Southern Morocco part of the Atlas mountains. The resin exudes naturally on the stems of the tree. It is also obtained by making cuts on the bark. It solidifies when exposed to the air. It comes to commerce in the form of small solid chips, translucent, and having a delicate yellow tinge. Morocco has been the main place of origin of sandarac. A similar resin is obtained in southern Australia from some species of the Australian cypress-like trees Callitris, but the resin has not been systematically collected in Australia.
Historically, especially in the Late Medieval and Renaissance era, sandarac was used to make varnish. When “varnish” was spoken of in Renaissance Italy (Italian vernice) it usually meant sandarac. Copal and other resins displaced it as equally good, less expensive varnishing materials. Nevertheless the sandarac varnish is still valued today for use as a protective coating on paintings and antiques. It gives a coat which is hard, lustrous and durable. The varnish is made by melting the resin and mixing it with (e.g.) linseed oil (or, in our case, Lavender oil). Sandarac resin melts at about 150°C. to a colorless or slightly yellow liquid.
Lavender Oil NF
(Dutch – Lavendel Olie German – Lavendelöl French – huile de lavande Spanish – aceite de lavanda )
Lavender oil is an essential oil obtained by distillation from the flower spikes of certain species of lavender. Two forms are distinguished, lavender flower oil, a colorless oil, insoluble in water, having a density of 0.885 g/mL; and lavender spike oil, a distillate from the herb Lavandula latifolia, having density 0.905 g/mL.
(Dutch – gedestilleerd water German – destilliertem Wasser French – l’eau distillée Spanish – agua destilada )
water that has been treated by boiling and condensation to remove solids, inorganics, and some organic chemicals.
