Eucalan is a no-rinse wash, meaning that the formula delicately releases dirt into the wash basin, cleaning fabric without the need of a final rinse through. Though the fabric absorbs a little of the soap, it has beneficial properties. Lanolin fortifies & conditions clothing fibres - particularly great for woolens & knits, but can be used on most anything. Jasmine Essential Oil: Jasmine oil is a natural antiseptic making it perfectly suited for your most delicate fibres. Of all Eucalan options, this is our strongest scent and has quickly become a fan favourite.
