The Truth About SLS and All Natural Product Alternatives

Sodium Lauryl Sulfate (SLS) is one of those ingredients that pops up everywhere—from shampoos and toothpaste to dish soaps and laundry detergents. It’s a cleansing agent known for its ability to create a rich lather, making products feel more effective. But while it’s great for foaming up your favorite shampoo, it’s not always great for your skin, health, or even the environment.


What is SLS, and Where is it Found?

SLS is a surfactant, which means it helps break down oils and grease so water can rinse them away. That’s why it’s in so many cleaning and personal care products. You’ll find it in:

  • Shampoo and conditioner

  • Toothpaste and mouthwash

  • Face wash and body wash

  • Dish soap and laundry detergent

  • Even some household cleaners

It’s effective, cheap, and widely used—but that doesn’t necessarily mean it’s the best option.


Is SLS Safe?

Regulatory agencies like the FDA and EPA consider SLS safe for consumer use in small amounts, but they acknowledge that it can cause irritation, especially for people with sensitive skin. The OSHA (Occupational Safety and Health Administration) even warns about its potential to cause skin and eye irritation in industrial settings.

The biggest concern isn’t necessarily the SLS itself but how often we’re exposed to it. Many people use multiple products containing SLS every day, leading to prolonged contact with a known irritant. For those with sensitive skin, eczema, or allergies, that can be a problem.


Why Should You Be Cautious?

While SLS isn’t classified as a toxic ingredient, frequent exposure has been linked to:

  • Skin & Scalp Irritation – It can strip away natural oils, leading to dryness, itchiness, and irritation.

  • Eye Sensitivity – If you’ve ever felt that shampoo sting, SLS is likely the culprit.

  • Potential Contaminants – Some SLS production methods can lead to contamination with 1,4-dioxane, a byproduct linked to cancer.

  • Environmental Impact – SLS doesn’t break down easily in water, contributing to pollution and harming aquatic life.


What Are the All Natural Product



Alternatives?

If you’re looking to cut back on SLS, there are plenty of alternatives out there. Many brands now offer SLS-free options that use gentler, plant-based cleansers like:

  • Coconut-derived surfactants (like sodium cocoyl isethionate)

  • Baking soda for toothpaste

  • Castile soap for body and household cleaning

These alternatives clean just as well—without the risk of irritation or environmental harm.


Final Thoughts

SLS isn’t necessarily dangerous, but it’s something to be mindful of, especially if you have sensitive skin or prefer more natural products. Reading labels and knowing what’s in your everyday essentials can help you make better choices for both your health and the environment. And with so many SLS-free options available, switching to a gentler alternative has never been easier.
