pH chart

the pH - potential hydrogen - is a measure of the acidity or alkalinity of a solution

the pH scale ranges from 0-14.

any solution with a pH below 7 is an acid and any solution with a pH above 7 is an alkali.

your stomach contains hydrochloric acid and has a pH of 1-2. the liquids in your small intestine have a pH around 9, distilled water has a pH of 7.

all natural soaps should be made using a ‘soap calculator’. this will calculate the amount of lye required for different oils ensuring a ‘safe to use’ soap. our soaps are kept at their natural pH of an alkali. 

traditionally it is said - you should wash with an alkali and rinse with an acid. this is still true today.

if a soap feels good on the skin then the pH of that soap is ok.
