Aminomethyl propanol is a pH adjuster that can also be found in lotions, hair and skin care products. It alters the pH of a product to improve stability. Every formula has an optimum pH to make it work best. For example, a formula that is more acidic works better for soap scum removal. Its opposite, a formula that is more alkaline, might be more effective as a carpet cleaner. We use pH adjusters to make sure we achieve the best pH for a particular job. Also, the pH of a formula can affect how long it lasts within a container – for example limiting its tendency to corrode a tin, container or dispenser. In this way, aminomethyl propanol is also used as a corrosion inhibitor in some of our products.
