Definition:
Sodium Hydroxide
Sodium Hydroxide is a builder that can also be found in detergents and degreasers. It makes a product formula clean better by affecting the molecules in the formula so they work together better. Sodium Hydroxide 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 formula that’s more acidic works better for soap scum removal. Its opposite, a formula that’s more alkaline, 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 rust in a can. In high concentrations (such as in drain cleaners), Sodium Hydroxide can also be used as a caustic that helps dissolve organic matter like drain clogs.
Interested in researching ingredients? Here are some commonly used sources.
We make ingredient choices based on scientific research and our own scientists’ expertise and perspective. But even scientists sometimes disagree about how or where certain ingredients should be used. We encourage anyone with questions to read up on areas of debate. That way, you can make the choices you feel are best for your family. Here are independent sources – both consumer and scientific – spanning various industries that use ingredients similar to ours:
