Is soap acidic or alkaline?

A common question, with the simple answer being that soap is alkaline. You could say that alkaline is the opposite of acidic.

What pH level does soap have?

However, different soaps have different pH levels. The product’s pH level can often be found on the packaging or in its safety data sheet.

What does alkaline mean?

In “chemistry terms,” bases are a group of chemical compounds that can absorb hydrogen ions. When dissolved in ordinary water, they produce a pH value above 7 or, more generally, donate electron pairs. Such a solution is said to be basic or alkaline. Alkaline is another word for basic.

Why use an alkaline soap?

• The advantage of an alkaline soap, one with a high pH value, is that it easily removes all dirt originating from plants or animals. It may sound strange?! But when you think about it, most of the dirt in our homes comes from plants or animals. Dirt brought in on shoes and outerwear, or by dirty animal paws, most likely comes from nature. The dirt we want to remove in the kitchen often comes from plants or animals—in other words, the food we have prepared. All of this can be easily and naturally removed with an alkaline soap.
• Another major advantage of an alkaline soap is that it removes and prevents the regrowth of, for example, mold. Mold is a type of fungus, and fungi do not thrive in an alkaline environment. Have you ever encountered a pink, reddish, or brown coating on the grout between your bathroom tiles? It is probably a fungus. Scrub with a soap that has a high pH value. It is a good idea to leave a little soap on the affected areas to work, and the mold infestation will give way.
• The same applies to algae and lichen. Algae often attack outdoor items such as garden furniture, window sills, pots, greenhouses, and boats. Algae do not thrive in an alkaline environment either and will stay away longer if you use a soap with a high pH value.
