The pH is an indicator of the acidity or alcalinity of a substance.This measure has a scale between 0 and 14, so it is acid if its pH is less than 7, neutral if equal to 7, and basic or alkaline if greater than 7.
Each different color indicates a different pH value.
The vast majority of bar natural soaps have a alkaline pH (between 8 and 10), while natural liquid soaps are usually more neutral.This light alcalinity of the natural soap pills is normal and is what makes it antiseptic, in addition, removes the excess acidity of the skin.
