Summary
Three ounce tin containing Tromax brand Fuller's Earth, made (or distributed) by Sigma Co. Ltd. 
Sigma was founded in 1912 by two Melbourne pharmacists, Ernest Holloway Leete (1870-1953) and Edwin Thomas Church (1864-1947). Initially the business made proprietary pharmaceutical and hygiene-related products for shareholder pharmacists, including tooth powder, soap, hair lotion, tonic, catarrh remedy, rheumatic salts, and kidney and backache pills. In 1942 the business opened a new manufacturing facility in Port Melbourne; in 1961 the factory moved to Clayton. Sigma remains a significant wholesale and distribution business to pharmacy and owns Amcal, Amcal Max and Guardian.
According to participants at a talk given by History Dept. at the Tresize Centre, 27 March, 1990, amongst its uses Fuller's Earth was also used as a "dry shampoo" to clean hats: it was sprinkled on and then brushed off.
