Kerzon Multi-Purpose Laundry Soap
Elevated everyday clean
The fabrics we live in stay close to the skin all day- the sheets we sleep in, the clothes we wear, the towels that wrap our children after a bath. What we wash them with matters more than we realise.
Crafted in France, Kerzon’s natural laundry soap brings a gentler philosophy to everyday washing. Made through traditional saponification using biodegradable olive and coconut oils, it cleans effectively while respecting fibres, skin, and the washing machine itself.
Unlike conventional detergents formulated with aggressive surfactants and synthetic additives, natural soap lifts dirt and rinses away cleanly, leaving fabrics soft, comfortable, and free from heavy residues.
Dermatologically tested and gentle enough for sensitive skin, babies, and the whole family.
Impeccable in the machine. Exemplary by hand.
Kerzon performs beautifully in both machine washing and hand washing.

Yes, Kerzon is gentle and suitable for sensitive skin.
Recent studies have shown that many regular laundry detergents, especially those containing harsh surfactants like SDS (sodium dodecyl sulfate), can weaken the skin barrier, increase water loss, and trigger inflammation. This happens because small traces of these detergents often remain on clothes and stay in contact with your skin all day.
Kerzon works differently. It’s made with true natural soap from saponified olive and coconut oils, without those aggressive surfactants. It cleans effectively but rinses much cleaner, making it far gentler on both skin and fabrics.
If you have very sensitive skin or specific concerns, it’s always a good idea to do a small patch test first.
-
Yes, you can. All Kerzon laundry soaps are dermatologically tested and made with gentle, natural ingredients.

If your baby has very sensitive skin, we recommend doing a small patch test first.

Yes, all Kerzon Laundry soaps work well for handwashing. Just add 1–2 caps to a basin of lukewarm water, gently agitate the garments, and rinse thoroughly.
