Suitable for sensitive skin
The natural pH level of human skin is acidic, whereas laundry detergents, soap, and washing soda are alkaline.
This is why clothing containing laundry detergent residue may cause skin irritation. The laundry rinse neutralises alkaline substances and helps the water rinse them off the clothing.
The slightly acidic rinse neutralises rinsing water, which is particularly important for people with sensitive skin, eczema or allergies, as well as for small children.
