Diisopropanolamine is a cleaning agent that can also be found in detergents and degreasers. We use it to make a product formula clean better by affecting the molecules in the formula so they work together better. Diisopropanolamine can also be a pH adjuster that alters the pH of a product to improve stability. Every formula has an optimum pH to make it work best. For example, a more acidic formula works better for soap scum removal. Its opposite, a more alkaline formula, might be more effective at removing grease or greasy soils. 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 can, container or dispenser.
