Caution when diluting soaps: expert warning

Experts warn that thrifty consumers who dilute liquid soap, shower gel or shampoo with water should be careful. These cleaning products often contain preservatives that prevent the growth of bacteria and pathogens. If they are subsequently diluted with water, the concentration of these substances decreases and germs can spread more easily. In addition, bacteria already present in the bottle or pump can grow and multiply in the diluted solution. Pump dispensers that contain residual moisture are particularly prone to germs. Experts recommend emptying dispensers completely and cleaning them thoroughly before refilling. Homemade shower foam, in which shower gel is mixed with water, also carries a high risk of germ contamination and can lead to skin irritation, allergic reactions or eczema formation. It is advisable to use up diluted liquids within two to four weeks to reduce the health risk. The most popular form of soap in Germany is liquid soap, which is preferred by 67 percent of people
