Sodium Lauryl Sulfate (SLS) with a 95% purity level, commonly indicated as SLS95, is utilized in toothpaste formulations for its various functional properties as an effective surfactant. Here’s how SLS95 is applied in toothpaste:
1. Foaming Agent: SLS95 generates a satisfying foaming action which helps to spread the toothpaste evenly throughout the mouth, ensuring that the scrubbing action of the bristles reaches between teeth and along the gum line for a thorough clean.
2. Detergent Properties: As a surfactant, SLS95 reduces the surface tension in the oral cavity, allowing for the removal of dental plaque, food debris, and stains from the teeth, contributing to a cleaner mouth feel.
3. Solubilizing Agent: SLS95 aids in solubilizing the components of toothpaste, such as flavor oils and therapeutic agents, ensuring that these ingredients do not separate and remain evenly distributed throughout the product.
4. Emulsifying Agent: It helps to emulsify and stabilize the mixture of water-soluble and oil-soluble ingredients in toothpaste, maintaining the homogeneity of the product during its shelf life.
Despite the effectiveness of SLS95 in toothpaste, its use is not without controversy. Some consumers experience sensitivity to SLS, as it can irritate oral tissues and potentially contribute to the formation of canker sores. Additionally, there is an increasing trend towards more ‘naturally’-formulated toothpastes that avoid SLS and similar chemicals, catering to those who prefer a gentler approach to oral care. Manufacturers may thus take into consideration the potential for such sensitivities and market demands when formulating their toothpaste products.paste products.
