Perfect for washing delicate fabrics, silk, wool and specially treated micro-fibre fabrics such as waterproof sports and outdoor clothing. Great for hand washing, particularly for people with sensitive skin. Made entirely from vegetable materials, it doesn't contain any chemicals, is Biodegradable and isn't tested on animals. Our colleague, Francis, used to wash his chickens with Soap Flakes prior to blow drying and showing them. The mind boggles!
