pH Test paper
pH testing is an essential aspect of soapmaking that determines the level of acidity or alkalinity in the soap. pH stands for "potential of hydrogen," and it is a measure of the concentration of hydrogen ions in a solution. In soapmaking, the pH of the soap plays a critical role in determining its quality and effectiveness.
A pH value below 7 indicates acidity, while a pH value above 7 indicates alkalinity. The ideal pH range for soap is between 8 and 10, which provides a mild and gentle cleansing experience for the skin.
