Ceteareth-20 is an emulsifier that can also be found in moisturizers, conditioners and other cosmetics. There is some debate about this ingredient’s use in cosmetics. However, since we use it in candles, and not applied to the skin, we believe it is acceptable for use. Ceteareth-20 helps bind ingredients together and keep a formula from separating. Over time, it is possible for formulas in household products to separate. We add emulsifiers to our products where needed to ensure that the products provide the same performance use after use.
