... After the dryer, everything is gone. Just as with pure essential oils. I use Sonnet detergent and soap nut products for health reasons and will have to cope for the same reasons with fragrance-free laundry. For Lenor- and Persil noses that's almost impossible to live without such a chemical cloud of perfume. I therefore hope that it succeeds Sapdu to make this great aroma a bit more durable.
