Sodium lauryl sulfate

Sodium lauryl sulfate

Sodium lauryl sulfate (SLS), which is also popularly known as sodium dodecyl sulfate (SDS) is a type of surfactant which is most often used in toothpastes. Sodium dodecyl is anionic in nature. It is extremely effective in removing the stains and dirt from items. Besides being used as an ingredient in some types of toothpastes, sodium lauryl sulfate is commonly used in engine degreasers, car wash soaps and floor cleaners. Sodium lauryl sulfate gives the toothpaste a foamy effect.

Toothpastes which use sodium lauryl sulfate as an ingredient can be precarious since research and study have shown that people who use these toothpastes commonly suffer from the problem of aphthous ulcers. Aphthous ulcer is most popularly known as canker sore.

Constant exposure of sodium lauryl sulfate to the skin can also cause irritation. Hence, sodium lauryl sulfate also damages the mucous membrane in the oral cavity. The harshness of SLS leads to numerous problems of the oral cavity. SLS also has the potential to cause taste alteration because it also reduces the perception of sweetness.

It has been observed that individuals who suffer from recurrent canker sores, when changing their toothpaste to an SLS-free toothpaste, get relief from the problem.

Another problem which sodium lauryl sulfate can cause is halitosis, more commonly known as chronic bad breath. SLS causes the salivary glands to produce less quantity of saliva which causes mouth dryness. Mouth dryness leads to various conditions, which include halitosis and formation of tooth decay.
