Effect of Sodium Dodecyl Sulfate(cas 151-21-3) on the Formation of Acquired Membrane

Sodium dodecyl sulfate (SDS, cas 151-21-3) is often used as a detergent and is widely used in toothpaste. SDS has a high affinity for hydroxyapatite (HA), and the binding of SDS to HA is used to interfere with the adsorption of HA on the protein. In this study, the effects of SDS on HA adsorption protein and the effect of enamel on the formation of accessory membrane in oral cavity were observed by UV spectrophotometer and scanning electron microscope.

The results showed that the amount of HA adsorbed protein after SDS treatment was significantly lower than that of untreated HA. The ability of SDS-treated enamel tablets to form the access membrane in the oral cavity was also significantly lower than that of untreated enamel. 

Tip: SDS(cas 151-21-3) can interfere with the protein adsorption of tooth surface, inhibit the formation of the membrane, with a certain anti-plaque effect.
