Non-Toxic Laundry Guide: Detergent, Wool Balls & More

Key Takeaways

  • Laundry pods are a microplastic concern — the dissolvable plastic film (PVA polymer) does not fully break down in wastewater treatment and has been detected in waterways, making them one of the easiest swaps to make.
  • Powder detergent is the lowest-chemical-burden option at most price points — it skips the preservatives, dyes, and petroleum-based surfactants that liquid formulas require to stay shelf-stable.
  • Wool dryer balls + washing soda + baking soda cover 90% of what you actually need from dryer sheets, fabric softeners, and synthetic boosters — at a fraction of the cost.

Why Does Laundry Even Matter for Pregnant Women and Babies?

You're already reading labels on food. You've probably swapped your skincare. But laundry? It's easy to forget that the clothes sitting against your skin — and against your newborn's skin — all day long were soaked in detergent residue that never fully rinses out.

Skin is not a perfect barrier. Residues from fragrances, optical brighteners, and surfactants in conventional detergents can be absorbed transdermally and may contribute to hormone disruption and skin sensitization. The National Institutes of Health notes that dermal absorption of chemicals is a real and often underestimated route of exposure, particularly in infants whose skin barrier is still developing.

This isn't meant to scare you. It's meant to show you why this swap is actually worth making — and that it doesn't have to cost more or take more time.

What's Actually in Conventional Laundry Detergent?

Most conventional liquid detergents contain a combination of:

  • Synthetic fragrances — "fragrance" on an ingredient label can represent a cocktail of hundreds of undisclosed chemicals, some of which are known endocrine disruptors (meaning they can interfere with your hormones) (EWG)
  • Petroleum-based surfactants — including ingredients linked to skin and respiratory irritation
  • Optical brighteners — synthetic chemicals that coat fabrics to make them appear whiter under UV light; they serve no cleaning function and can irritate sensitive skin
  • 1,4-Dioxane — a likely human carcinogen (meaning a chemical that may promote cancer development) found as a byproduct of certain surfactant manufacturing, flagged by the EPA and detected in several popular laundry products
  • Preservatives — required in liquid formulas to prevent microbial growth; many are associated with skin sensitization

Liquid detergents need preservatives to stay shelf-stable. Powder detergents generally don't. That one difference alone removes several categories of concern.

Is Powder Detergent Actually Better Than Liquid?

In most cases, yes — and it's often cheaper too.

Powdered detergents, even conventional supermarket options, tend to have a shorter and simpler ingredient list than their liquid counterparts. Because the formula is dry, manufacturers don't need to add the preservatives, synthetic emulsifiers, or dyes that keep liquid products from separating or growing mold on the shelf.

One practical note: powder detergents can sometimes leave residue if used in cold-water cycles. The fix is simple — dissolve your measured amount (less is more with powder; resist the urge to pour generously) in a cup of warm water before adding it to the machine.

Start here this week: Switch your next detergent purchase to powder. You don't have to throw out what you have.

SCRUNCHY MOM TIP: With powder detergents, start with half the recommended amount. Most formulas are concentrated and the instructions tend to overshoot what you actually need — which saves you money and reduces residue on fabrics.

What About Laundry Pods — Aren't They Convenient?

They are convenient. They're also one of the more straightforward swaps to make once you understand why.

Almost every conventional laundry pod is wrapped in a polyvinyl alcohol (PVA) film designed to dissolve in water. The problem is that it doesn't fully disappear — it persists in wastewater and has been identified as a significant microplastic concern. Research published in PLOS ONE found that PVA from laundry pods is not fully removed by wastewater treatment plants and accumulates in the environment.

Beyond the environmental concern, pods carry all the same issues as liquid detergent — synthetic fragrance, petroleum surfactants, and preserved formulas — just in a single-use plastic film.

If you only do one thing from this section, do this: Stop buying pods. Switch to a powder or a concentrated liquid from one of the brands below.

What Should You Use for Laundry Boosters?

Mainstream laundry boosters — including the popular scent bead products — are almost entirely synthetic fragrance suspended in a plastic or wax carrier. They serve no meaningful cleaning function and are a significant source of fragrance chemical exposure that lingers in fabric long after washing. The NIH has noted that synthetic fragrance ingredients include known and suspected endocrine disruptors and allergens.

The good news: you don't need them. A simple combination of washing soda (sodium carbonate) and baking soda (sodium bicarbonate) is genuinely effective. When these two ingredients are activated in water, they release oxygen, which deodorizes laundry, helps lift stains, and brightens whites — without the synthetic chemical load. This is the foundation of most clean oxygen booster products on the market.

Start here this week: Add ¼ cup of baking soda to your next laundry load in place of any scent booster or brightener you currently use.

Do Wool Dryer Balls Actually Work?

Yes — and they replace two products you're probably already buying: dryer sheets and fabric softener.

Wool dryer balls work by physically separating clothing in the dryer drum, which allows hot air to circulate more efficiently. This reduces drying time (which saves energy and money), softens fabric through gentle mechanical action, and reduces static — especially when used in sets of 3–6. They're reusable for hundreds of loads.

Conventional dryer sheets are coated in synthetic fragrance and fabric-softening chemicals (often quaternary ammonium compounds) that transfer onto clothes and then onto skin. For a newborn's laundry especially, this is an easy and permanent swap to make.

Look for 100% New Zealand wool options without synthetic coatings or added fragrances. If you want a light scent, a single drop of a high-quality essential oil on one ball is sufficient — and gives you full control over what's on your baby's onesies.

SCRUNCHY MOM TIP: For baby laundry, always choose unscented — no essential oils, no fragrance of any kind. Baby skin absorbs more relative to body weight than adult skin, and their immune systems are still calibrating to the world.

What to Use for Stain Treatment?

Most commercial stain sprays rely on synthetic solvents, optical brighteners, and fragrance. For most stains, a paste of baking soda and a small amount of dish soap (unscented, plant-based) applied before washing handles the job.

For protein-based stains (breast milk, blood, baby food) — cold water first, always. Hot water sets protein stains permanently.

An oxygen-based cleaner (washing soda activated with warm water) is effective for tougher stains and is a safer choice than chlorine bleach, particularly during pregnancy and around infants.

If you only do one thing from this section, do this: Keep a small jar of baking soda near the laundry and treat stains before they dry. Fresh stains are almost always easier to lift than set ones.

FAQ

Q: Is it safe to use essential oil–scented detergents during pregnancy?

Essential oils are not automatically safe because they're "natural." Some essential oils — including clary sage, rosemary, and certain citrus-based compounds — have been flagged for caution during pregnancy. If you're choosing a scented option from any of the brands listed above, verify that the essential oils used are certified organic, clearly disclosed, and not on the cautionary list from your midwife or OB. The simplest approach: go unscented during pregnancy and for all baby laundry.

Q: How many wool dryer balls do I actually need?

For a standard load, 3 balls is the functional minimum. For large or heavy loads (towels, bedding), 6 balls is more effective at reducing drying time and static. More balls = better air circulation = shorter drying time = lower energy bill.

Q: Can I use washing soda in a high-efficiency (HE) washing machine?

Yes, but use it sparingly. Washing soda is a booster, not a standalone detergent, and HE machines use less water — which means undissolved particles can leave residue if you overdo it. Start with 2 tablespoons dissolved in warm water before adding to the drum, and skip it on delicate cycles.
