Eucalan is a no-rinse soap that can be used to wash sweaters, handwovens, or any delicate fabrics. No rinsing is necessary, so you'll use less water. The soap is non-toxic, biodegradable, and free of phosphates, synthetic fragrance, and dye. It contains natural lanolin, which conditions the fibers and helps reduce static. It can be used for washing by hand or machine. This 16.9-ounce bottle contains enough soap for approximately 45 washes.
