Good, clean, old-fashioned soap.

Soap flakes are something your grandmother, or great-grandmother, might remember using to wash linens and laundry. And today, fans of low-waste, all-natural cleaning products are looking back to soap flakes as a long-lasting, chemical-free alternative to detergents. Fer à Cheval’s soap flakes are made from their iconic Marseille soap. In fact (buckle up), the name “Marseille Soap” is a protected designation—to qualify for this highly-coveted label, your soap has to be made in Provence with natural oils and just a handful of other ingredients: seawater, ash and lye. At Fer à Cheval, it’s a labor-intensive process that takes 10 days and starts with boiling the ingredients in ancient cauldrons overseen by a soap master and team of artisans. So to bring this all back to “soap flakes,” you’ll find zero preservatives, dyes, additives or animal fats in these flakes, making it a biodegradable, certified organic and environmentally friendly alternative to chemical detergents. Plus, it’s allergen-free for even the most sensitive skin.
