fifoam soaps use only pure essential oils to add aroma. No synthetic fragrances or extracts. The essential oils are the most expensive ingredient in the soap and there are three Ranges of soap - Everyday, Premium and Specialty that are based on the price of the essential oils. The Everyday Range uses the lowest cost oils that are tried and tested favourites. Lavender, Lemongrass, Spearmint and Tea Tree. The Premium Range uses mid-tier oils that are mostly grown and distilled in Australia. Australian Lavender, Honey Myrtle, Indian Sandalwood and Rose Geranium. The Specialty Range uses pure Australian Sandalwood oil distilled in Western Australia. The strength of the aroma in any of the soaps can be adjusted by varying the dilution of the concentrate.
