This Ingredient May Be Hiding in Most of Your Toiletries
What is Sodium Lauryl Sulfate (SLS)?
Sodium Lauryl Sulfate (SLS) is a common ingredient found in many products that foam, such as shampoos, body washes, and even toothpaste (P.S. This is why toothpaste foams up!). It’s a type of detergent that helps create bubbles and clean your skin or hair. While generally considered safe, SLS can cause issues for those with sensitive skin. Over time, repeated use might lead to skin irritation or sensitivity.
If you have skin conditions like eczema, dermatitis, psoriasis, or just sensitive skin in general, removing SLS from your daily routine could make a big difference. It's worth considering a switch to a more gentle cleanser for sensitive skin to help soothe and protect your skin from irritation.
The International Journal of Toxicology claims that SLS isn't harmful provided it meets these conditions:
- It's used for short durations.
- It's thoroughly rinsed off of skin.
- It doesn't exceed a concentration of 1%.
According to the NIH report (see link above), Sodium Lauryl Sulfate concentrations of more than 2% can cause skin irritation. But the concentration of SLS in household cleaning products can vary from 1% to 30%. In toiletries like bubble baths and body cleansers, SLS concentrations can range even higher.
Popular global forums like Reddit show plenty of Redditors sharing in the r/eczema pages about the positive transformations they have seen since going SLS-free:
SLS can be derived from either petroleum-based or plant-based sources like palm or coconut oil. It is often used in higher concentrations in studies to irritate the skin, allowing researchers to test products designed to soothe it. Even at lower concentrations, SLS can still cause irritation for some people, especially those with existing skin conditions.
SLS vs. Sodium Laureth Sulfate (SLES)
Sodium Laureth Sulfate (SLES) is a gentler version of SLS, but it may still cause reactions in those sensitive to SLS. Both ingredients can be found in a wide range of products, even in those labeled as "green" or "natural." If you are sensitive to one, it's best to avoid both.
Who Should Avoid SLS?
If you have sensitive skin, eczema, psoriasis, or other skin conditions, avoiding SLS may help prevent flare-ups. Eliminating SLS from your skincare products could improve your skin over time. You can try reintroducing it later, but you may find that avoiding it altogether is best for your skin’s health.
The National Eczema Society of England also recommends avoiding SLS even in your shampoos. We may be used to thinking that shampoos that lather are doing a better job at cleansing our body or hair, but the National Eczema Society confirms that this is untrue, and refers to SLS as a "national eczema irritant".
Are There Alternatives to SLS?
Some alternatives to SLS, like Sodium Cocosulfate (SCS) or Sodium Lauryl Sulfoacetate (SLSA), are derived from natural sources like coconut oil and are less irritating due to their larger molecular size. However, those with very sensitive skin may still want to avoid them.
What’s the Best Body Wash for Sensitive Skin?
For sensitive skin, especially if you're looking for a body wash for eczema or dermatitis, it's best to avoid products with harsh detergents. Look for natural, moisturizing products like bar soaps made with simple, gentle ingredients that won’t strip your skin.
