How many ingredients does it take to make a natural laundry detergent? For us, four. Water, sunflower soap, soda crystals, and the lavandin essential oil we distill every summer on the Valensole plateau. Nothing else.<\/p>

As lavender growers for 4 generations and organic since 2002, we wanted a laundry detergent whose label you can read all the way through. Here’s what it contains, who makes it, how to dose it to the nearest milliliter, and how much a wash really costs.<\/p>

Turn over a bottle of conventional laundry detergent: synthetic surfactants, optical brighteners, enzymes, preservatives, fragrance\u2026 The list is long, and often hard to understand.<\/p>

A natural laundry detergent is based on a plant-based soap, a few simple minerals, and a naturally derived scent. The word “natural” has no legal definition for laundry detergents: the only real benchmark is the composition and the labels printed on the bottle. So here is ours, ingredient by ingredient.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  1. Cold-saponified sunflower oil.<\/b> The heart of the formula. Turned into soap through cold saponification, with 8% surfat, it forms the washing base. Palm oil free.<\/li>
  2. Water, less than 30%.<\/b> While a conventional liquid laundry detergent is mostly made of water, ours contains less than 30%. That’s what makes it ultra-concentrated.<\/li>
  3. Soda crystals.<\/b> Extracted in France, they support the soap: they remove stains, cut through grease, help whiten fabrics, and limit the effects of limescale.<\/li>
  4. Our organic lavandin essential oil.<\/b> Grown, harvested, and distilled right here, in Valensole. It alone gives your laundry its scent. No synthetic fragrance.<\/li><\/ol>

    Composition: water (less than 30%), 5 to 15% anionic surfactants (cold-saponified sunflower oil), soda crystals, organic lavandin essential oil (naturally contains linalool, a potential allergen). Certified organic ingredients.<\/em><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Lavandin, the signature scent of the Valensole plateau<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Every summer, when the plateau turns purple, we harvest our lavandin and distill its flowering tops. This fresh, slightly camphorous essential oil is the one you find in your laundry detergent.<\/p>

    Lavandin (Lavandula \u00d7 intermedia<\/i><\/a>) is a natural hybrid between true lavender and spike lavender. Richer in essential oil than fine lavender, it is ideal for the home and laundry. Its scent remains delicate on clothes: it smells like clean laundry drying in the sun, not like detergent.<\/p>
