Are There Chemicals in Baby Wipes? (What's Really in That 99% Water)

The Short Answer

Yes, there are chemicals in baby wipes. Even the "purest" brands require preservatives to prevent mold and bacteria from growing in a wet environment. The question isn't if there are chemicals, but which ones are safe for a newborn's permeable skin.

The "99% water" claim is technically true but misleading. It's the remaining 1% that causes diaper rash, allergic reactions, and long-term toxicity concerns. That 1% often includes preservatives like phenoxyethanol, surfactants to remove grease, and texture enhancers.

Recent data has raised the stakes: A class-action lawsuit proceeding in 2025 alleges that Costco's Kirkland Signature Baby Wipes contain PFAS ("forever chemicals"), despite being marketed as natural. This highlights a critical gap in regulation—what's not on the label can hurt you.

Why This Matters

Baby skin is thinner and more absorbent than adult skin.

Whatever you wipe on their bottom doesn't just sit there; it gets absorbed. This is especially true in the diaper area, where occlusion (being covered by a diaper) increases chemical absorption rates significantly. Are Diapers Safe

Preservatives are necessary evils.

You don't want moldy wipes. But the industry standard preservatives have shifted from parabens (bad) to methylisothiazolinone (bad allergen) to phenoxyethanol (current standard, but still controversial). We are trading one toxicity risk for another. Is Phenoxyethanol In Baby Wipes Safe

Microplastics are hidden in plain sight.

Many parents don't realize that the wipe itself is often plastic. Conventional wipes are frequently made of a polyester-polypropylene blend. You are essentially wiping your baby with liquid plastic, which smears millions of microplastic fibers onto their skin with every change.

What's Actually In Baby Wipes

Here is the breakdown of the "other 1%" found in most standard wipes:

• Phenoxyethanol — The most common preservative in "natural" wipes. It prevents bacteria but can depress the central nervous system in infants if ingested (or absorbed in high amounts). It is restricted for use in baby products in Japan. Is Phenoxyethanol In Baby Wipes Safe
• Fragrance (Parfum) — A "black box" ingredient. By law, companies can hide hundreds of chemicals, including hormone-disrupting phthalates, under this single word. Is Fragrance In Baby Wipes Harmful
• Polysorbate-20 / PEG-40 — Emulsifiers that keep the solution mixed. These are ethoxylated ingredients, meaning they are processed with ethylene oxide and can be contaminated with 1,4-dioxane, a probable human carcinogen.
• Benzalkonium Chloride — A harsh disinfectant often found in "water wipes" (including the brand WaterWipes) as a trace contaminant or preservative. It is a known skin irritant. Is Waterwipes Clean
• Plastic Fibers — Unless the package says "100% plant-based" or "cotton," the cloth is likely polyester.

What to Look For

Green Flags:

• "100% Plant-Based" or "Plastic-Free" — Ensures the wipe material isn't polyester.
• EWG Verified — The gold standard for avoiding hidden contaminants.
• Food-Grade Preservatives — Look for Sodium Benzoate or Potassium Sorbate instead of stronger synthetic preservatives.
• Total Chlorine Free (TCF) — Ensures the wipe material wasn't bleached with chlorine.

Red Flags:

• "Fragrance" or "Parfum" — Immediate avoid. Is Fragrance In Baby Wipes Harmful
• Methylisothiazolinone (MIT) — A potent allergen causing contact dermatitis. Huggies removed this years ago, but off-brands still use it.
• Bronopol / DMDM Hydantoin — Formaldehyde releasers. Rare now, but still exist in dollar-store brands.
• "Unscented" — Tricky marketing. "Unscented" means they added chemicals to mask the smell. Look for "Fragrance-Free" instead.

The Best Options

You want a wipe that is plastic-free, fragrance-free, and uses gentle preservatives.

The Bottom Line

1. Read the back, not the front. Ignore "Hypoallergenic" and "Natural." Look for Phenoxyethanol and Fragrance on the ingredient list.

2. Ditch the plastic. Switch to wipes labeled 100% plant-based or cotton. It reduces microplastic exposure and is better for the planet.

3. Wash when you can. For pee diapers at home, you can use a reusable cloth with warm water. It's the only way to be 100% chemical-free.

FAQ

Are WaterWipes actually chemical-free?

No. They are 99.9% water, but the 0.1% fruit extract contains a trace amount of benzalkonium chloride. While much cleaner than standard wipes, they are not strictly "chemical-free." Is Waterwipes Clean

What does "Hypoallergenic" actually mean?

Nothing. It is an unregulated marketing term. A product can be labeled hypoallergenic and still contain known allergens like fragrance or MIT. Always check the ingredient list.

Can I flush "flushable" wipes?

Never. Even if they say flushable, they do not break down fast enough for most plumbing systems and contribute to massive "fatbergs" in city sewers. Throw them in the trash. Are Organic Diapers Worth It
