The pH of soap can vary depending on the type and ingredients used. Generally, the pH of soap falls within the range of 8 to 10, with most soaps landing between 9 and 10. Handmade soaps typically have a pH between 8 and 10, with a safe range for use on the skin being between 10 and 8. A pH above 11 is considered too harsh for the skin and may cause irritations. Its important to note that the pH of soap is an essential characteristic for skincare products, but it doesnt directly indicate how harsh or mild a specific product is. The pH level is crucial for determining the readiness of the soap for use on the skin and for ensuring that it is safe and effective.
