Let’s Talk About: Sodium Lauryl Sulfate (SLS) and Canker Sores
Sodium Lauryl Sulfate (SLS) is a ubiquitous ingredient found in numerous personal care and food products, used for its ability to create foam and lather... even when unnecessary. While commonly used in toothpaste and foods, the benefits of SLS come with potential drawbacks, particularly when it comes to oral health. In this blog, we'll delve into what SLS is, its uses, the effects it has on oral tissue, and explore alternatives for those seeking gentler options. Plus, discover how products like The Canker Spanker can provide relief from SLS-induced canker sores and mouth ulcers.
What is SLS?
Sodium Lauryl Sulfate (SLS) was discovered in the early 20th century by German chemists. It was first synthesized in the 1930s as a surfactant, a type of compound that lowers the surface tension between two substances, making it easier to mix them together. Initially, SLS was primarily used in industrial settings, such as in cleaning agents and detergents, due to its excellent foaming and cleaning properties.
The widespread adoption of SLS in consumer products began in the mid-20th century when its effectiveness as a surfactant was recognized by the personal care and food industries. Companies started incorporating SLS into various products, including toothpaste, shampoos, body washes, and food items, to enhance their cleaning power and create a foamy lather that consumers associated with cleanliness.
One of the key reasons SLS gained popularity in personal care products is its ability to efficiently remove dirt, oil, and food particles from surfaces. In toothpaste, for example, SLS helps create a foamy texture that enhances the sensation of cleanliness and leaves the mouth feeling fresh. Similarly, in food products, SLS acts as an emulsifier and preservative, extending shelf life and maintaining product quality.
Overall, the discovery of Sodium Lauryl Sulfate revolutionized the personal care and food industries, providing manufacturers with a versatile and effective ingredient to improve the performance of their products and enhance the user experience for consumers.
There are benefits to SLS
Cleaning Power: SLS effectively removes dirt, oil, and food particles from the surface, providing a thorough cleaning experience.
Foaming Action: The foaming action of SLS creates a sense of freshness and cleanliness, enhancing the overall user experience.
Preservation: In food products, SLS helps extend shelf life by preventing microbial growth and maintaining product quality.
There are Definitely Negative Effects on Oral Tissue and Canker Sores
Despite its benefits, SLS has been linked to various oral health issues, including irritation and inflammation of oral tissue. Prolonged exposure to SLS can disrupt the delicate balance of the oral microbiome, leading to increased sensitivity and a higher risk of developing canker sores and mouth ulcers. The abrasive nature of SLS can strip away the protective layer of the oral mucosa, leaving it vulnerable to irritation and discomfort.
Are there Alternative Ingredients and Products?
Fortunately, there are SLS-free alternatives available for those seeking gentler oral care options. Look for toothpaste formulations that contain natural ingredients such as:
Sodium Lauroyl Sarcosinate
Cocamidopropyl Betaine
Sodium Coco-Sulfate
