How does potassium soap work?
- Potassium Soap (potassium oleate): Natural soap that emulsifies grease and dirt — cleans thoroughly without harsh surfactants.
- Decyl Glucoside (non-ionic surfactant): enhances degreasing and is gentle on sensitive textile fibres.
- Sodium citrate (potassium citrate): works as a water softener — prevents limescale deposits on fibers that turn white laundry gray.
- Expectation: With regular washing at 30–40 °C: white and light fabrics remain bright after several washes.
