Verwenden
Arabinogalactan is a gum, being the plant extract obtained from
larch trees. it is soluble in hot and cold water, the water solutions up
to 60% being fluid and above 60% forming a thick paste. it is stable
over a wide ph range and is relatively unaffected by electrolytes. its
limited uses include dressings and pudding mixes. it is also termed
larch gum.
synthetische
Natural turpentine is obtained from tapping or scraping the wounds on a variety of coniferous trees. Separating the essential
oil and solid content of crude turpentine makes pure gum spirits. The crude gum is heated, refined and separated by distillation
into gum spirits and rosin.
