LAVOIR was born from a simple place: home.
La Lessive is a short list, and we think you should be able to see all of it.
Below is every ingredient in the tin, in the order it appears in the wash.
What’s inside
Marseille soap flakes — saponified from vegetable oil (sodium palmate, sodium palm kernelate, sodium chloride, water, sodium hydroxide as a processing residual at well under 1%).
A fragrance compound, developed for us and sourced from Grasse.
Water.
Fragrance allergens
In line with California’s Cleaning Product Right to Know Act (SB 258), we name any fragrance allergen present in the finished product at or above 0.01% (100ppm) individually, rather than folding it into “fragrance”:
| Ingredient | CAS number | Present at |
|---|---|---|
| Terpineol | 8000-41-7 | ≥0.01% |
| Eucalyptus Globulus Oil | 8000-48-4 | ≥0.01% |
| Lavandula (Lavender) Oil/Extract | 8000-28-0 | ≥0.01% |
All other fragrance constituents are present below this threshold.
Designated lists
We checked every declared ingredient in La Lessive’s fragrance and soap base against California’s designated chemical lists, including Proposition 65. None of them appear on any of these lists.
