Sigma was founded by two Melbourne pharmacists in 1912, it has grown to become one of the key players in Australia’s pharmacy industry .Edwin Thomas Church (1864 – 1947) and Ernest Holloway Leete a prominent chemist and a member of the College of Pharmacy who had established his own pharmacy in 1897. The entrepreneurial Leete had been part of a move in 1904 among a group of commercially-minded chemists to put up proprietary preparations. 1913 - 1927 Initially, the fortunes of the Sigma enterprise relied on E. H. Leete ‘working from home’, and even as late as 1915 company address was in Claremont Avenue Malvern. Following the establishment of the business in 1912, the Sigma Company Limited was located at Flinders Lane, Melbourne. Sigma – Tromax, 1928 E.H. Leete after sixteen years, said he would not stand again as a director of the company because interests were also turning elsewhere. He was assisting another company as its agent in the motor trade. 1938 to1953 was characterised by steady growth for Sigma, accelerated by manufacturing opportunities during World War Two. Between 1975 and 1996 the company was transformed as it entered a period of both consolidation and rapid growth. The appointment, in 1996, of new Managing Director, George Savvides, marked a break from the past. Today Sigma is a leading full line wholesale and distribution business to pharmacy. Sigma is also the owner of some of Australia’s best known pharmacy brands in Amcal, Guardian and Amcal MaxA triangular shaped, brown glass, bottle with a metal screw top containing ‘Campholine’Front label : Campholine / Camphorated / Mineral Oil / CAUTION ! / Use strictly in accordance / with the directions / Adults : Rub briskly on parts affected .

Potassium permanganate is an inorganic chemical compound with the chemical formula KMnO4. Formerly known as permanganate of potash or Condy's crystals, it is a strong oxidizing agent. It dissolves in water to give intensely pink or purple solutions, the evaporation of which leaves prismatic purplish-black glistening crystals. c1859 London chemist Henry Bollmann Condy had an interest in disinfectants; he found that fusing pyrolusite with sodium hydroxide (NaOH) and dissolving it in water produced a solution with disinfectant properties. He patented this solution, and marketed it as 'Condy's Fluid'. Although effective, the solution was not very stable. This was overcome by using potassium hydroxide (KOH) rather than NaOH. This was more stable, and had the advantage of easy conversion to the equally effective potassium permanganate crystals. This crystalline material was known as 'Condy's crystals' or 'Condy's powder'. Potassium permanganate was comparatively easy to manufacture.A brown glass bottle with a red plastic topped cork stopper for 'Tromax' , 'Purple Crystals' ie Permanganate of Potash , that was used as an antiseptic and disimfectant.TROMAX BRAND / PURPLE CRYSTALS/ or Permanganate of Potash / (Poisonous )/ For Household and Medicinal Uses / 2oz. / TROMAX / A PRODUCT OF/ SIGMA Co.Ltd. / MANF.
