Sodium citrate is a builder that can also be found in various household products, including shampoos, mascara, and lipstick. We use it to make a product formula clean better by affecting the molecules in the formula so that they work together better. It can also be used as a stabilizer that maintains the clarity of the product and protects its pH. 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. To ensure product performance, it is important that our product formulas maintain their stability over time.
