Why Does Sodium Lauryl Sulfate Have a Bad Reputation?

Why Does Sodium Lauryl Sulfate Have a Bad Reputation?

In modern life, Sodium Lauryl Sulfate (SLS) is almost everywhere, from toothpaste to shampoo to facial cleanser, its applications are wide. Although SLS is widely used for its superior lathering and cleaning abilities, it is also controversial for a number of reasons.

So why is Sodium Lauryl Sulfate (SLS) cause for concern?

1. Skin and mucous membrane irritation: SLS has been proven to be irritating to skin and mucous membranes. Prolonged exposure to high concentrations of SLS may cause dry redness and itchiness of the skin. This makes some people reject products containing SLS.

2. Mouth ulcers and SLS in toothpaste: Some studies show that toothpaste containing SLS may worsen the problem of mouth ulcers in some people. This has caused some consumers to have doubts about SLS and believe that it is harmful to oral health.

3. Controversy over the potential carcinogenicity of SLS: Although there is no sufficient scientific basis, there are still rumors circulating on the Internet that SLS may have carcinogenic risks. This unconfirmed information has caused widespread public concern.

These factors have combined to create a negative image of SLS, causing some consumers to have reservations about products containing SLS.

Is the Sodium Lauryl Sulfate (SLS) we come into contact with every day safe?

Although there is controversy about the safety of SLS, both the U.S. Food and Drug Administration (FDA) and the U.S. Cosmetic Ingredient Review Panel (CIR) have assessed and shown that SLS is safe at conventional concentrations.

Studies have pointed out that SLS is less irritating to skin and mucous membranes at concentrations below 1%. In many daily cosmetics, the concentration of SLS is usually controlled between 0.5% and 2%. For example, the concentration of SLS in toothpaste is generally between 0.5% and 1.5%, while the concentration in shampoo and body wash may be between 1% and 2%.

Only when the concentration exceeds 2% SLS may cause the skin to be dry, redness, itching, and other uncomfortable symptoms. When 20% and above, SLS becomes significantly more irritating and corrosive, making it unsuitable for use in daily products.

Therefore, the concentration of SLS contained in daily chemical products is usually within a safe range and is safe for the human body. However, consumers still need to choose reputable brands when purchasing in order to ensure the product’s compliance and safety and to avoid potential health risks.

Why does the public have this misunderstanding?

Due to the spread of the Internet and the media, many misconceptions about Sodium Lauryl Sulfate (SLS) have been widely spread. For example, some people mistakenly believe that SLS is a carcinogen, but this statement is actually not supported by scientific evidence. The root cause of this misunderstanding is often misinformation and poor public understanding of chemical ingredients. Some websites and social media platforms may have exaggerated the potential risks of SLS and misled the public.

Through fact-checking and scientific explanations, these misunderstandings can be effectively clarified and consumers can correctly understand the actual impact of SLS. For example, neither the U.S. National Toxicology Program (NTP) nor the World Health Organization (WHO) lists SLS as a carcinogen. In addition, the personal care products using SLS are considered safe after multiple scientific studies and evaluations by regulatory agencies. It is crucial to provide correct scientific information, not only to eliminate unnecessary panic but also to increase consumer confidence in the product.
