Isobutane is a propellant used to dispense a product from a container. It is often used in concert with other propellants such as butane and propane. While isobutane is commonly known for its use as a fuel, for example for camp stoves, in use as a propellant its energy comes from being compressed in a can rather than from being lit or heated.

Sodium hydroxide is a builder 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 that 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 corrode a can, container, or dispenser. 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.

Tetrasodium iminodisuccinate is a chelator that can also be found in laundry detergents, hand soaps, and dishwashing detergents. The word chelator (pronounced "key-lay-tor") comes from the Greek word chele, or claw. Think of a chelator as a tiny claw that reaches out and grabs the minerals in soap scum or soils to keep them from being deposited on a surface. We use tetrasodium iminodisuccinate in products to remove soap scum and mineral deposits. By binding to the soap scum or deposit, it allows either to be rinsed away.
