Is Regular Laundry Detergent Safe for Baby Clothes?
The short answer: most conventional laundry detergents are not ideal for baby clothes, but you don't need an expensive specialty product to do better. You just need to know what to avoid and what to swap in.
TL;DR:
- Most conventional laundry detergents contain synthetic fragrance, optical brighteners, and petroleum-based surfactants that can irritate a baby's more permeable skin barrier.
- Powder detergents are generally a safer starting point than liquid because they require fewer preservatives and are less likely to contain dyes or synthetic fragrance.
- You don't need a separate "baby detergent" — a fragrance-free, dye-free option safe for the whole family works just as well and costs less.
Key Takeaways
- Synthetic fragrance is the biggest red flag. The FDA classifies fragrance as proprietary, meaning companies don't have to disclose the individual ingredients, which can number in the hundreds and include known endocrine disruptors.
- Baby skin is structurally different from adult skin. A newborn's skin barrier is thinner and more permeable, meaning residue left behind in fabrics can absorb more readily than it would on your skin.
- Powder detergents, even conventional ones, tend to have fewer concerning ingredients than liquid formulas because they don't require the liquid-stabilizing preservatives, dyes, and synthetic emulsifiers that liquid versions do.
Why Does Baby Laundry Detergent Even Matter?
If you've been tossing your baby's onesies in with the regular family laundry and feeling vaguely guilty about it, you're not alone.
Here's the thing: your baby wears clothing against their skin for 16 to 20 hours a day. Detergent residue doesn't fully rinse out after a single wash cycle. That means whatever is in your detergent can linger in fabric fibers and stay in contact with your baby's skin, hour after hour.
Newborn skin isn't just "more sensitive" in a vague, marketing-speak way. It's structurally different. Research published in the journal Pediatric Dermatology shows that infant skin has a thinner stratum corneum (the outer protective barrier) and a higher surface-area-to-body-weight ratio, making it more permeable to both water loss and external chemicals.
What this means for your family: Residue from detergent left in fabric is more likely to penetrate your baby's skin than your own, which is why ingredient choices matter more, not less, in the newborn stage.
That doesn't mean you need to panic. It means you need a checklist.
What's Actually in Conventional Laundry Detergent?
What Are Endocrine Disruptors, and Are They in My Detergent?
Endocrine disruptors are chemicals that can interfere with the body's hormonal system, meaning they mimic, block, or otherwise alter the signals that hormones send. The NIH's National Institute of Environmental Health Sciences recognizes endocrine-disrupting chemicals as a significant area of concern, particularly for pregnant women and infants.
Synthetic fragrance is one of the biggest sources. The FDA classifies fragrance formulas as proprietary trade secrets, which means brands are not required to disclose what's actually inside their "fragrance" ingredient. That single word on a label can represent hundreds of individual chemical compounds, including phthalates, which are associated with hormone disruption.
What this means for your family: "Fragrance" on any baby product label, including laundry detergent, is a signal to pause and look for an unscented alternative.
What Are Optical Brighteners, and Why Should I Avoid Them for Baby Clothes?
Optical brighteners (also called fluorescent whitening agents) are synthetic chemicals added to detergents to make fabrics appear whiter and brighter under light. They work by absorbing UV light and re-emitting it as visible blue light, which creates the illusion of brightness rather than actually cleaning the fabric.
The catch: optical brighteners are designed to stay in fabric. They don't rinse out. That's how they keep working wash after wash. The Environmental Working Group (EWG) flags certain optical brighteners as potential skin sensitizers and notes concerns about aquatic toxicity.
For everyday adult laundry, this is a nuisance. Against a newborn's skin, it's a reason to skip them entirely.
SCRUNCHY MOM TIP: Run an extra rinse cycle on baby clothes for the first few months, especially if you're transitioning away from your old detergent. This helps clear any residual buildup from previous washes.
Liquid vs. Powder Detergent: Which Is Safer?
This is one of the most practical swaps you can make, even before you switch brands.
Liquid detergents require preservatives to stay stable in water-based formulas. That's where many of the concerning ingredients show up: synthetic preservatives, petroleum-based surfactants, dyes added for aesthetics (not function), and excessive synthetic fragrance.
Powdered detergents, even conventional ones from the grocery store, tend to skip many of these additives because they don't need liquid-stabilizing ingredients. They're also less likely to contain 1,4-Dioxane, a probable human carcinogen (meaning a chemical associated with cancer risk) that can form as a byproduct during the manufacturing of certain liquid surfactants. The EPA has flagged 1,4-Dioxane as a likely human carcinogen based on animal studies.
If the only change you make is switching from liquid to powder detergent, that's meaningful progress.
Do You Actually Need a Special "Baby Detergent"?
No, and the marketing around baby-specific laundry detergents is worth some skepticism.
Many popular baby detergents still contain synthetic fragrance (just labeled as "baby fresh" instead of "lavender"), optical brighteners, and preservatives. The "baby" label is not a regulated safety claim. It's a marketing category.
What you actually need is a detergent, for babies and adults alike, that is:
- Fragrance-free (not "unscented," which can mean the fragrance was masked)
- Free of optical brighteners
- Free of dyes
- Made with plant-based or naturally derived surfactants
One fragrance-free, dye-free formula that's genuinely clean can safely wash your baby's clothes, your clothes, and everyone's sheets. Simpler and more affordable.
Detergent Options by Category
| Format | Safety Profile | Budget Friendliness | Best For |
|---|---|---|---|
| Conventional liquid (scented) | Lowest — dyes, fragrance, preservatives | Low cost per bottle, lower value | Not recommended for babies |
| Conventional powder (unscented) | Better — fewer preservatives, no dyes | Most budget-friendly starting point | Transitional option |
| Clean liquid laundry soap | Good — depends on brand transparency | Mid-range | Families who prefer liquid |
| Clean powder (vetted brand) | Best — minimal ingredients, no liquid stabilizers | Mid-range, concentrated | Newborns, sensitive skin, all family laundry |
| Concentrate-based system | Best — one product, multiple uses | High value long-term | Families wanting to simplify |
What to Use Instead: Good/Better/Best
Good — Conventional Powder, Unscented
If you're not ready to switch brands, switching format is a legitimate first step. An unscented conventional powder detergent from the grocery store will have fewer concerning ingredients than a fragranced liquid. Not perfect, but progress.
Start here this week: Check your current detergent for the words "fragrance," "parfum," or any dyes (often listed as "Blue 1" or "Yellow 5"). If you see them, that's your cue to swap the next time you run out.
Better — Vetted Clean Brands
Molly's Suds Original Laundry Detergent Powder is a well-regarded option created by a pediatric nurse and mom. It's formulated without carcinogens or harsh chemicals, comes in powder form, and is a practical middle ground for families on a budget.
Mama's Suds Laundry Soap is a family-owned Castile-based liquid laundry soap. Note that it's a soap, not a detergent, which matters for homes with hard water. It's free from 1,4-Dioxane and synthetic preservatives, and it's safe for cloth diapers.
Attitude Baby is another widely available option, fragrance-free and EWG-verified for several of its formulas. Available at many retailers, making it an accessible pick.
If you only do one thing from this section, do this: Replace your current detergent with a fragrance-free, dye-free option on your next purchase. You don't have to order anything special, just read labels at the store.
Best — Concentrate-Based System
The Scrunchy Non-Toxic Home Starter Kit includes a Multi-Surface Concentrate that's EWG Verified, one of the few concentrates to hold that product-level certification. For laundry, you mix 1 part concentrate with 2 parts water to make a laundry solution, then add ¾–1 capful to the detergent dispenser per load. The Brightening Powder (also included) can be added directly to the drum before clothes for whitening and odor removal without bleach, ammonia, or synthetic fragrance. The kit also includes a year of ScrunchyAI, which lets you scan ingredient labels to flag concerning ingredients, useful when evaluating new products.
Branch Basics is another concentrate-based option worth considering, with a similar concentrate-and-dilute approach and strong ingredient transparency.
SCRUNCHY MOM TIP: Always choose unscented for babies, even if a brand uses essential oils rather than synthetic fragrance. For newborns especially, fragrance-free is the standard to hold.

FAQ
Q: Can I just use my regular detergent for baby clothes if I do an extra rinse?
An extra rinse helps reduce residue, but it doesn't fully solve the problem if your detergent contains synthetic fragrance, optical brighteners, or petroleum-based surfactants. These ingredients are designed to cling to fabric fibers. That's how optical brighteners work, by staying in the fabric wash after wash. A clean, fragrance-free detergent is a more reliable solution than adding a rinse cycle to a problematic formula.
Q: Are "free and clear" detergents from mainstream brands safe enough for babies?
They're better than fragranced versions, and removing dyes and fragrance is meaningful. But "free and clear" is not a regulated standard, and some mainstream "free and clear" formulas still contain petroleum-based surfactants, preservatives that can be irritating, or trace 1,4-Dioxane from the manufacturing process. Checking the specific product on EWG's Guide to Healthy Cleaning (ewg.org) takes about 30 seconds and gives you a much clearer picture than the label alone.
Q: Do I need to wash new baby clothes before the first wear?
Yes, and this applies before any product swaps. New clothing, including baby clothing, can contain finishing chemicals, sizing agents, and residue from manufacturing and shipping. Washing before first wear removes these surface chemicals regardless of which detergent you're transitioning to. If you're using the Scrunchy concentrate system, the laundry solution works on new items just as it does on regular loads.
