Sodium lauryl sulfate (SLS) is the sodium salt of lauryl sulfate. SLS is used as a surfactant, foaming agent or emulsifier, helping oil-based and water-based ingredients to stay mixed. In the Tom’s of Maine natural toothpaste that contains SLS, it is derived from vegetable sources and helps properly disperse ingredients during brushing and ensures easy rinsing and removal of debris (i.e., food particles).
Sodium lauryl sulfate (SLS) is frequently confused with sodium laureth sulfate (SLES). Despite common myths about SLS, it has a long history of safe and effective use. Tom’s of Maine offers both SLS and SLS-free toothpaste.
