The Parent's No-Nonsense Guide to Choosing a Safe Laundry Detergent for Your Baby
Share
When you have a new baby, you suddenly start reading labels on everything. Ingredients in lotion, dyes in wipes, chemicals in cleaning sprays — things you probably never thought twice about before. Laundry detergent is often the last thing on the list, but it probably deserves to be near the top.
Here's why: baby skin is up to five times thinner than adult skin, making infants significantly more vulnerable to chemical absorption from detergent residues on clothing, blankets, and bedding. Your baby wears clothes all day and sleeps in sheets all night. Whatever is in those fabrics — including residue from whatever you washed them with — is in contact with their skin constantly.

Does your baby actually need a special "baby detergent"?
Not necessarily. Many products marketed as baby detergents are gentler than standard detergents, but "baby" on the label isn't a regulated claim — any brand can use it. What actually matters is the ingredient list, regardless of whether the packaging has a duck on it.
Ingredients to avoid for baby laundry
Synthetic fragrance is the first thing to rule out. As with adult detergents, "fragrance" can legally hide hundreds of chemical compounds, some of which are known allergens and hormone disruptors. For newborn skin, fragrance-free is the only safe choice.
Optical brighteners are chemicals that make clothes appear whiter by absorbing UV light. They're not doing any cleaning — they're purely cosmetic. The problem is they stay in fabric even after rinsing, sitting against baby's skin. Skip them.
Dyes serve no cleaning purpose and are a documented skin sensitizer. There's no reason for a laundry detergent to be blue or green.
Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are surfactants used to create foam. They work, but they can strip natural oils and irritate delicate skin.
Preservatives like methylisothiazolinone (MI) and methylchloroisothiazolinone (MCI) are flagged by dermatologists as significant allergens. They're common in liquid detergents.
Enzymes, often added for stain-fighting power, can also trigger reactions in sensitive infants.
What to look for instead
You want a short ingredient list — ideally five to ten ingredients at most, all with names you can look up and understand. Fragrance-free (truly fragrance-free, not "unscented," which can still contain masking agents). Dye-free. No optical brighteners. No sulfates if you can avoid them. And ideally, a third-party certification like EWG Verified that means someone other than the brand has actually checked the formula.
Practical tips for washing baby clothes
Use less detergent than the label suggests. Detergent residue is a direct function of how much you use — a smaller amount cleans effectively and leaves less behind. Run an extra rinse cycle, especially for the first few months. Wash new baby clothes before the first wear — they often have manufacturing residues and sizing chemicals that can irritate skin right out of the package. Skip fabric softener and dryer sheets entirely. They coat fabrics with fragrance and synthetic chemicals, exactly what you're trying to avoid.
About EcoGlo for baby laundry
EcoGlo has five ingredients: sodium percarbonate, sodium carbonate, sodium bicarbonate, sodium gluconate, and sodium chloride. No fragrance, no dyes, no optical brighteners, no preservatives, no sulfates. It's EWG Verified, which means EWG's team of toxicologists reviewed the formula and confirmed it meets their strictest safety standards.
Several of our customers have specifically told us they switched because their babies or grandchildren were developing hives or rashes, and that the reactions stopped after switching. That's not something we take lightly — it's exactly the problem this product was designed to solve.
Your baby's skin is doing a big job while it's developing. The least we can do is make sure the fabric touching it all day is as clean as it can possibly be.
