I use it for my baby linen. The smell is neutral (unscented). The machine is more flexible and gentle with the laundry detergents with "classic". Do not overfill (follow recommended doses) and in a dosing ball, with a machine fills just right, and she will dissolve very well. By cons if there are large stains, you better pre-treated, because it has no strong detaching power. Used with Cat Adoussissant Ecological, a must see!
