NINGBO INNO PHARMCHEM CO.,LTD. explores the multifaceted role of Sodium Dodecyl Sulfate (SDS) in everyday oral hygiene, specifically within toothpaste formulations. SDS is a common ingredient in many toothpastes due to its cost-effectiveness, its ability to create a desirable foam, and its contribution to the overall cleaning action. As an anionic surfactant, its primary function in toothpaste is to help distribute the active ingredients across the oral cavity and to lift and remove food particles and plaque through its detergent properties.

The foaming action of SDS is a key reason for its inclusion. The lather it produces helps in the mechanical removal of debris and provides a sensation of cleanliness. However, its use in toothpaste has also been a subject of discussion regarding potential side effects. Some studies suggest that SDS may contribute to dry mouth (xerostomia) in certain individuals, although the evidence is not conclusive. The mechanism proposed involves the removal of protective mucus layers, which can lead to a feeling of dryness.

Furthermore, a notable concern linked to SDS in toothpaste is its potential association with recurrent aphthous ulcers, commonly known as canker sores. Several studies have investigated this connection, with some indicating that toothpastes containing SDS may lead to a higher incidence or severity of mouth ulcers in susceptible individuals. The theory suggests that SDS might disrupt the protective mucosal barrier in the mouth. For consumers or manufacturers looking to manage this, sourcing toothpastes without SDS or using alternative surfactants is an option. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality SDS, understanding its widespread use and the ongoing discussions around its applications. We aim to provide clarity on its chemical formula (CH3(CH2)11OSO3Na) and functional properties for informed product development.
