About Sodium Hydroxide

Sodium Hydroxide is an inorganic base.[1] Its solubility and charge state vary depending on the components forming the salt and the formula’s acidity, which also affects how it interacts with other ingredients. In cosmetics, it is used to buffer the formula so its acidity does not change rapidly and to alter the taste or odor of a raw material so it is difficult to ingest.[2]
