Cleaner Sodium Lauryl Sulfate

Sodium Laureth Sulfate is a common foaming agent that may cause irritation due to its harshness or byproducts. Avoid it for 8 weeks, use gentle products, and support recovery with calming supplements to help reduce sensitivity.

🧴 What is Sodium Laureth Sulfate (SLES)?

Sodium Laureth Sulfate (SLES) is a foaming agent and surfactant commonly found in personal care products like shampoos, body washes, facial cleansers, and toothpaste. It helps these products lather and remove oils and dirt from skin or hair.

🤔 Why Do I Have an Intolerance to Sodium Laureth Sulfate?

An intolerance to SLES is usually due to your body reacting to its harsh chemical composition or impurities like 1,4-dioxane, a byproduct sometimes present in SLES. Key reasons you might be sensitive include:

  • Skin Barrier Disruption: SLES can strip the skin of natural oils, leading to dryness, irritation, and increased sensitivity.

  • Inflammatory Reaction: Your body might trigger an inflammatory response when exposed to SLES, especially if you have underlying skin conditions like eczema, rosacea, or dermatitis.

  • Chemical Sensitivity: Some individuals are naturally more reactive to synthetic chemicals, especially when used frequently or in combination with other ingredients.

🛠️ What Can I Do About It?

To help your body recover and reduce symptoms:

  • Avoid SLES-containing products for at least 8 weeks to give your skin and system time to reset.

  • Read ingredient labels on all personal care and cleaning products—look out for names like Sodium Laureth Sulfate, Sodium Lauryl Sulfate (SLS), and ammonium lauryl sulfate.

  • Use gentle, SLES-free products, preferably labeled as sulfate-free or made for sensitive skin.

  • Retest after 8 weeks to see if sensitivity has improved.

💊 Supplements to Support Recovery from Sensitivity to Sodium Laureth Sulfate

These supplements may support your skin barrier, reduce inflammation, and help detoxify your system:

  • Omega-3 Fatty Acids – Help calm skin inflammation and repair the skin barrier.

  • Quercetin – A natural antioxidant that reduces allergic-type inflammation and supports histamine balance.

  • Milk Thistle – Supports liver detox pathways, which helps your body clear synthetic chemicals more efficiently.

🌟 Why Might I Have an Intolerance to Sodium Laureth Sulfate but Not Sodium Lauryl Sulfate?

While both are surfactants, they differ in structure and processing:

  • Sodium Laureth Sulfate (SLES) is ethoxylated, which introduces 1,4-dioxane, a potential irritant.

  • Sodium Lauryl Sulfate (SLS) is a simpler molecule without ethoxylation, but still a known irritant—yet some people tolerate it better due to its different chemical behavior.

  • SLES is milder in theory, but ironically, its processing impurities can make it more irritating for sensitive individuals.

  • Your body may be reacting specifically to the ethoxylation byproducts in SLES rather than the base surfactant.
