Eau de Cologne is a perfume said to have been invented by the Italian chemist, Johann Maria Farina, who settled at Cologne in 1709. The original recipe is unknown, though several chemists in Cologne have long claimed to be the sole owners of it. The general principle of Eau de Cologne is alcoholic vegetable extracts, essential oils and rectified spirits. The usual recipe prescribes twelve drops of each of the essential oils, bergamot, citron, neroli, orange and rosemary, with one dram of Malabar cardamoms and a gallon of rectified spirits which are distilled together. Later recipes used highly purified spirits and made further distillation unnecessary. Research Eau de Cologne
