Fragrance is the most common cause of contact dermatitis in infants, and laundry detergent is one of the highest-exposure household products that touches a baby’s skin. The good news: switching to a fragrance-free, dye-free detergent resolves the majority of low-grade rash and skin irritation cases within two to three wash cycles. The bad news: marketing makes the choice unnecessarily complicated. This guide cuts through the labels to explain what fragrance-free actually means, how it differs from unscented, which brands deliver, and how to wash baby clothes correctly.
A note: this guide is informational. For persistent rashes, eczema, or specific skin questions, consult your pediatrician or a pediatric dermatologist.
Fragrance-free versus unscented, the critical distinction
The two terms are commonly used interchangeably but mean different things:
Fragrance-free. No fragrance ingredients added. The product may have a faint chemical smell from the cleaning ingredients themselves but no perfume or parfum.
Unscented. A masking fragrance has been added to cover the smell of the underlying cleaning chemicals. The product reads as neutral-smelling but contains fragrance compounds.
For babies and people with sensitive skin, fragrance-free is the correct choice. Unscented can still trigger fragrance allergies. Look for the explicit phrase “fragrance-free” or “free of fragrance” on the label. In the ingredient list, “parfum”, “perfume”, “fragrance”, and “natural fragrance” all indicate added scent.
The FDA does not regulate the terms strictly, so reading the ingredients matters more than the front-of-package claim.
What ingredients trigger infant skin reactions
The most common detergent-related irritants:
- Synthetic fragrances. A single “fragrance” listing can contain 50 to 100 individual fragrance compounds, any of which can trigger contact dermatitis.
- Dyes. Blue, purple, or pink coloring agents in detergents have no cleaning function and add nothing but allergen potential.
- Optical brighteners. Chemicals that make fabrics appear whiter by reflecting UV light. Common ones include CBS-X and tinopal. Some cause photodermatitis on sun exposure.
- Enzymes. Protease, amylase, and lipase enzymes break down proteins, starches, and fats on clothes. Most babies tolerate them fine, but a small subset develops sensitivity.
- Phenols. Common in conventional detergent preservatives. Linked to skin and respiratory irritation.
A truly baby-friendly detergent is fragrance-free, dye-free, optical-brightener-free, and ideally low on phenols. Enzymes are usually fine but worth avoiding if a known sensitivity exists.
What the labels and certifications mean
Look for:
- National Eczema Association (NEA) Seal of Acceptance. The NEA tests products against criteria for eczema-friendly formulation. The seal indicates the product passed.
- EWG Verified. The Environmental Working Group’s verification confirms a product avoids EWG’s list of chemicals of concern.
- EPA Safer Choice. Less skin-focused, more about environmental safety, but products that earn it tend to skip the worst irritants.
- USDA Certified Biobased. Indicates plant-based content but not skin safety.
- Hypoallergenic. Unregulated marketing term. Look at the ingredient list instead.
The NEA seal and EWG Verified are the two most useful for baby skin specifically.
The brands that actually deliver
Reliable fragrance-free, dye-free detergents commonly cited in pediatric and dermatology literature:
- All Free Clear. The most widely available option. NEA-accepted. Effective cleaning, affordable, sometimes contains optical brighteners (check current formulation).
- Tide Free and Gentle. NEA-accepted. Strong cleaning power. Pricier than All. Available in liquid and pods.
- Seventh Generation Free and Clear. Plant-based formulation. EWG rated A. Slightly less effective on heavy stains but fine for baby clothes.
- ECOS Free and Clear Hypoallergenic. Plant-based, NEA-accepted, very low irritant profile.
- Mrs. Meyer’s Baby Blossom. Has a light scent (technically not fragrance-free). Skip if true fragrance-free is the goal.
- Dreft. Has a “baby fresh” scent. Skip for sensitive skin despite the baby marketing.
- Babyganics Laundry Detergent. Fragrance-free version exists. Plant-based.
- The Honest Company Free and Clear. Plant-based, fragrance-free option in the lineup.
- Charlie’s Soap. Minimal ingredients, fragrance-free, popular among cloth diaper users.
- Molly’s Suds. Concentrated powder, very short ingredient list, fragrance-free version available.
For most families, All Free Clear or Tide Free and Gentle is the most practical pick because availability is universal and the formulation is well-tested.
Hot, warm, or cold wash
Water temperature affects both cleaning effectiveness and fabric longevity:
- Hot (130 F or higher). Kills most bacteria, removes ammonia from cloth diapers, breaks down grease. Fades colors and shrinks some fabrics over time. Use for cloth diapers, burp cloths, anything heavily soiled.
- Warm (90 to 110 F). A good general purpose temperature. Effective on most stains, gentler on fabrics. Default for regular baby clothes.
- Cold (under 80 F). Energy-efficient. Less effective on grease and bacteria. Acceptable for lightly worn outerwear and items washed primarily for fragrance refresh.
For cloth diapers specifically, the recommended cycle is a cold rinse first (to break up solids), followed by a hot wash with detergent, followed by a warm rinse. This three-stage approach is supported by most cloth diaper manufacturers.
Pre-treatment for stains
Common baby stains and what works on them:
- Breast milk and formula spit-up. Cold water rinse immediately, then enzyme detergent. Hot water sets protein stains.
- Baby food (yellow, orange, green). Pre-treat with a stain stick (Tide to Go, Shout) or a paste of baking soda and water. Soak in cold water before washing.
- Yellow stains on white onesies. Sunlight is the cheapest bleach alternative. Wash, then dry the wet onesie in direct sun for 2 to 4 hours.
- Diaper blowouts. Rinse solids in the toilet, soak in cold water, then wash hot with extra detergent.
- Bloodstains (from cuts or umbilical stump). Cold water only, never hot. Hydrogen peroxide on a cotton ball lifts most fresh blood.
Avoid chlorine bleach on baby clothes when possible. Oxygen bleach (OxiClean Free, Nellie’s) is gentler on skin and effective on most stains.
Fabric softener and dryer sheets
Most conventional fabric softeners and dryer sheets contain fragrances, quaternary ammonium compounds (quats), and fatty acid coatings that can irritate infant skin and reduce the absorbency of cloth diapers and microfiber cleaning cloths.
Alternatives that achieve softer fabric without the irritants:
- Wool dryer balls. Three to six in the dryer reduce drying time by 15 to 25 percent and soften fabric naturally. Last 1,000 plus loads.
- White vinegar in the rinse cycle. Half a cup softens fabric, neutralizes residual detergent, and is rinsed out completely. No vinegar smell on dried clothes.
- Air drying. Skip the dryer when possible. Sun-dried clothes are naturally soft and smell clean without fragrance.
For static reduction in winter, wool dryer balls plus a slightly damp washcloth in the dryer reduce static more effectively than dryer sheets.
Decision framework
For everyday baby laundry, choose:
- Fragrance-free, dye-free detergent (All Free Clear, Tide Free and Gentle, or Seventh Generation Free and Clear)
- Warm wash, warm rinse for clothes
- Hot wash for cloth diapers and burp cloths
- Wool dryer balls or air dry
- Skip dryer sheets and fabric softener
- OxiClean Free for stains, sunlight for yellow stains
For eczema or sensitive skin, escalate to:
- NEA-sealed detergent (Tide Free and Gentle, ECOS Free and Clear)
- Double rinse cycle to remove any detergent residue
- Vinegar rinse occasionally to neutralize buildup
- Consult your pediatrician or a pediatric dermatologist for persistent reactions

Frequently asked questions
Is fragrance-free the same as unscented?+
No. Fragrance-free means no fragrance ingredients added at all. Unscented usually means a masking fragrance was added to cover the smell of the cleaning chemicals. The distinction matters for sensitive skin. Look for the explicit phrase fragrance-free on the label, and check the ingredient list for parfum or perfume.
Do I need a special baby detergent?+
Not necessarily. A regular fragrance-free, dye-free detergent like All Free Clear, Tide Free and Gentle, or Seventh Generation Free and Clear works fine for most babies. Dedicated baby detergents (Dreft, Babyganics) are usually slightly more expensive versions of the same fragrance-free formula. For babies with eczema or known sensitivities, consult your pediatrician for specific recommendations.
Should I wash baby clothes separately?+
For the first few weeks, washing new baby clothes once before first wear (to remove manufacturing finishes) is worthwhile. Beyond that, washing baby clothes with the rest of the household laundry in a fragrance-free detergent is fine. The exception is if other family members use heavily scented laundry products or fabric softener, in which case keeping baby items separate avoids fragrance transfer.
What temperature should baby clothes be washed at?+
Warm or cold for most clothes, hot for cloth diapers, burp cloths, and anything heavily soiled. Hot water (130 F or higher) kills bacteria and removes ammonia from cloth diapers but fades colors and shrinks some fabrics. Cold water is gentler on clothes and saves energy but is less effective on grease and bacteria. A warm wash with a cold rinse is the typical compromise.
Are dryer sheets safe for baby clothes?+
Most conventional dryer sheets contain fragrances and quaternary ammonium compounds that can irritate sensitive skin. Skip them for baby laundry. If you want softer fabric or static reduction, use wool dryer balls (Smart Sheep, Friendsheep) or a half-cup of white vinegar in the rinse cycle. For specific skin questions, consult your pediatrician.
