No. 2 Signature Eco Wash is a lovely mineral-based detergent. It is not a liquid but a non-biological powder formula which is gentle, effective at stain removal, and free from toxins and harsh chemicals. It is perfect for use at low temperatures and has a blissfully refreshing fragrance and a little (tiny 1 cap amount) goes a long way but beware..clour fast and prefeable light colours only..as it contains a (safe oxygen based) bleaching agent.
 
Also does it come in 100% aluminium, with a compostable label, so you can save the planet while you save your clothes.
