Is Sulfate in Body Wash Bad?

šŸ“… Updated February 2026ā±ļø 5 min readNEW

TL;DR

Yes, you should likely avoid them. Sulfates like SLS are potent skin irritants that strip your natural oils, while milder versions like SLES are frequently contaminated with 1,4-dioxane, a probable human carcinogen. If you have eczema, sensitive skin, or want to avoid hidden toxins, switching to a sulfate-free body wash is one of the easiest health upgrades you can make.

šŸ”‘ Key Findings

1

SLES (Sodium Laureth Sulfate) is often contaminated with 1,4-dioxane, a probable carcinogen.

2

SLS (Sodium Lauryl Sulfate) is a known skin irritant used in labs to induce dermatitis for testing.

3

Sulfate-free cleansers use glucosides and betaines that clean without stripping the moisture barrier.

4

California and New York have enacted strict limits on 1,4-dioxane in personal care products as of 2025.

The Short Answer

You should proceed with caution. While sulfates are effective at removing dirt and oil, they are often too effective, stripping your skin of the natural lipids it needs to stay healthy.

There are two main villains here:

1. SLS (Sodium Lauryl Sulfate): A harsh irritant that can damage your skin barrier and worsen eczema.

2. SLES (Sodium Laureth Sulfate): A milder cleanser that undergoes a chemical process called ethoxylation, which creates 1,4-dioxane—a likely human carcinogen—as a byproduct.

If you struggle with dry skin, eczema, or want to reduce your toxic load, switch to a sulfate-free body wash.

Why This Matters

Your skin barrier is your first line of defense.

Sulfates are surfactants (detergents) designed to break down oil. The problem is they don't distinguish between "dirt" and your skin's natural protective oils. Using strong sulfates daily contributes to Transepidermal Water Loss (TEWL), leaving your skin dry, itchy, and vulnerable to bacteria. See Is Face Wash Stripping Skin for how this affects your face.

The hidden cancer risk.

SLES was created to be less irritating than SLS. To do this, manufacturers use ethylene oxide, a known carcinogen. This process leaves behind traces of 1,4-dioxane.

You won't find 1,4-dioxane on the ingredient label because it's a "contaminant," not an ingredient. Testing has found it in dozens of conventional body washes, shampoos, and detergents.

Eczema is on the rise.

Dermatologists often recommend avoiding sulfates if you have atopic dermatitis. It’s one of the first things to cut if you have "mystery rashes." Check out Safest Body Wash for better alternatives.

What's Actually In Body Wash?

Most commercial body washes are 80% water and 20% chemistry. Here is what you are actually scrubbing with:

  • Sodium Lauryl Sulfate (SLS) — The "stripper." It creates massive bubbles but is so irritating that scientists use it as a control irritant to test healing creams. Is Sulfate In Shampoo Bad
  • Sodium Laureth Sulfate (SLES) — The "contaminator." It's gentler on skin but carries the 1,4-dioxane risk. If you see "Laureth" or "-eth," think "ethoxylation."
  • Cocamidopropyl Betaine — A much gentler surfactant derived from coconut. It’s a common "green" alternative, though it can still be an allergen for some.
  • Fragrance — The "black box." A single word that can hide hundreds of chemicals, including hormone-disrupting phthalates. Is Fragrance In Body Wash Bad

What to Look For

Green Flags:

  • Glucosides — Ingredients like Decyl Glucoside or Coco-Glucoside. These are ultra-gentle sugar-derived cleansers.
  • Isethionates — Sodium Cocoyl Isethionate is known as "baby foam" because it’s mild enough for infant skin.
  • Saponified Oils — Traditional soap made from oils (coconut, olive) and alkali. Look for Sodium Cocoate or Potassium Olivate.

Red Flags:

  • Sulfates — Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Ammonium Lauryl Sulfate.
  • PEG compounds — PEG-100, PEG-40. These also undergo ethoxylation and carry the same contamination risks as SLES.
  • Formaldehyde Releasers — Preservatives like DMDM Hydantoin. Is Dmdm Hydantoin Safe
  • Parabens — Endocrine disruptors used as preservatives.

The Best Options

You don't need harsh chemicals to get clean. Here are the top performers that skip the sulfates.

BrandProductVerdictWhy
AleaviaEnzymatic Body Cleanseāœ…Best Overall. Microbiome-friendly, edible ingredients, zero harsh detergents.
Dr. Bronner'sPure-Castile Soapāœ…Best Natural Classic. Concentrated and super clean. Dilute before use. Is Dr Bronners Body Wash Safe
NativeBody Washāš ļøAcceptable Mainstream. Sulfate-free and easy to find, but contains "Fragrance." Is Native Body Wash Clean
DoveDeep Moisture🚫Avoid. Contains SLES and heavy fragrance, despite the "moisturizing" claims. Is Dove Body Wash Safe

The Bottom Line

1. Read the label. If you see "Sulfate" or "PEG" in the first five ingredients, put it back.

2. Ignore the "Natural" claims. Brands love to slap "Natural" on bottles that still contain SLES. Look for specific certifications like EWG Verified or Made Safe.

3. Less lather is okay. Clean skin doesn't need to feel "squeaky." That squeak is actually the sound of your skin crying for moisture.

FAQ

Does sulfate-free body wash lather?

Yes, but the bubbles are different. Sulfates create big, airy, "fluffy" foam. Safer alternatives like coco-glucoside create a creamier, denser, more modest lather. It takes getting used to, but your skin will thank you.

Is Sodium Coco-Sulfate safe?

It depends on who you ask. Sodium Coco-Sulfate (SCS) is a blend of sulfates derived from raw coconut oil. It is technically a sulfate, but it is less processed than SLS. We rate it Acceptable, but if you have extreme sensitivity, stick to sulfate-free.

Can sulfates cause acne?

Yes. By stripping your skin of oil, sulfates can trigger a "rebound effect" where your skin overproduces sebum to compensate, leading to clogged pores and body acne. Is Body Wash Bad
