Gym Tonique is specially formulated for activewear and technical sportswear.

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, 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.
