Frequently Asked Questions

  • Mon Premier Déo is formulated specifically for children (ages 5+), with gentle, well-tolerated ingredients designed to respect young skin. It helps neutralise odour without blocking sweat, supporting the skin’s natural functions rather than interfering with them. Read more about why Mon Premier Deo is the better alternative to adult deodorants for your child here.

  • Yes, while TOOFRUIT is designed for children, it is equally suitable for teens and adults, especially those with sensitive or reactive skin who prefer gentle, well-tolerated formulas.

  • Kerzon uses natural laundry soap made from plant-based oils instead of synthetic detergents. For more information, see our article on Laundry Soap vs Detergent.

  • Multi-Purpose Laundry Soap: Ideal for everyday family washing. It’s gentle, effective, and leaves a soft, subtle scent on your clothes.

    Technical Versions:
    Maille Câline: Extra gentle for delicate items like lingerie, wool, knits, and baby clothes. It cares for fabrics while adding a comforting violet-cotton-vanilla scent.
    Gym Tonique: Designed for sportswear and technical fabrics. It helps neutralise odours and refreshes with invigorating citrus and juniper notes.

  • Gym Tonique is specially formulated for activewear and technical sportswear. While our Multipurpose Laundry Soap is great for everyday clothes and bedding, Gym Tonique is stronger at neutralising sweat, odours, and chlorine. It also helps protect the elasticity and performance of technical fabrics like gym leggings, sports bras, and swimwear.

  • 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. They are free from harsh surfactants, sulfates, and residues that can irritate sensitive or eczema-prone skin. Many parents use our soaps for baby clothes and bedding with good results. If your baby has very sensitive skin, we recommend doing a small patch test first.

  • Yes, you can use it for handwashing. Just add 1–2 caps to a basin of lukewarm water, gently agitate the garments, and rinse thoroughly.
