Abstract – Sodium lauryl sulfate (SLS) is widely used as a synthetic detergent in dentifrices. It has been shown to have high affinity for hydroxyapatite (HA), and the binding mechanism has been proposed to be electrostatic, involving the negative sulfate terminals of the SLS and the calcium sites on the HA.
