The Quick Answer

  • You don't need "Dreft" or specialized baby detergent. You need a "Free & Clear" detergent. The biggest irritants are fragrances and optical brighteners. Enzymes are generally safe and necessary for cleaning poop/milk stains, unless your baby has a confirmed specific biology issue.
Editor's NoteWe consulted dermatology guidelines for atopic dermatitis (eczema) and textile chemistry resources.

The "Baby Detergent" Scam

Many detergents marketed for babies are pink, heavily scented, and cost 2x more. Fragrance is the enemy: Newborn skin is thin and permeable. Fragrance allergens can trigger eczema. "Baby Scent" is just marketing.

The better choice: Any mainstream "Free & Clear" detergent (Tide Free, All Free, Seventh Generation Free) is likely safer than a scented baby detergent.

Section Summary

  • Fragrance triggers eczema
  • Baby branding often means higher price + scent
  • Free & Clear is the standard

Optical Brighteners: The Invisible Coating

Ever notice how white shirts glow under UV light? That's optical brighteners (like stilbenes). They don't clean; they coat fabrics with a chemical that reflects blue light to trick the eye. This chemical stays on the clothes—and on your baby's skin. Safety: They are known skin irritants and are toxic to aquatic life. Good non-toxic detergents skip them.

Enzymes: Friend or Foe?

Enzymes (protease, amylase) digest stains. You *need* them to clean cloth diapers or blowout stains. Myth: "Enzymes cause rashes." Fact: Modern enzymes rinse out effectively. Irritation is usually from leftover soap scum (using too much detergent) or fragrance. Unless your baby has a rare specific sensitivity, enzymes are safe and helpful.

“Optical brighteners are chemicals designed to stay on your clothes. Enzymes are designed to rinse away. Avoid the former; embrace the latter.”

Frequently Asked Questions

Common questions about chemical safety answered by our research team.

QWhat are optical brighteners in laundry detergents?

Optical brighteners are synthetic chemicals added to detergents to make fabrics appear whiter and brighter by absorbing UV light and emitting blue light. They persist on fabrics, in water, and soil, with common types like disodium distyrylbiphenyl disulfonate rated poorly for toxicity by the Environmental Working Group.[1][2]

QWhat health risks are associated with optical brighteners?

Exposure to optical brighteners can cause skin, eye, and respiratory irritation, especially in large amounts or for those with dye allergies. Animal studies suggest potential cancer risk, contact dermatitis, bioaccumulation, reproductive toxicity, developmental toxicity, and neurotoxicity via oxidative stress, as shown in C. elegans models.[1][2][3]

QAre optical brighteners safe for babies and sensitive skin?

No, optical brighteners are not safe for babies; they irritate sensitive skin, potentially causing rashes, eczema, or allergies in infants. Residues remain on clothes after washing, increasing exposure through skin contact, inhalation, or ingestion, which is riskier for developing systems unable to detoxify quickly.[4][5][7][8]

QWhat are the environmental impacts of optical brighteners?

Optical brighteners are persistent pollutants that biodegrade slowly, contaminating water, soil, and wastewater. They are acutely toxic to aquatic life, bioaccumulate in organisms, and evade water treatment, posing long-term risks to ecosystems despite some modern versions being less eco-toxic than older ones.[1][2][3]

QWhat is the 'Baby Detergent' scam?

The 'Baby Detergent' scam refers to marketing regular laundry detergents as 'gentle' or 'for baby' clothes despite containing harmful chemicals like optical brighteners, enzymes, dyes, and fragrances. These residues irritate infant skin, causing eczema or allergies, misleading parents into thinking they are safer.[4][5][7][8]

QAre enzymes in baby detergents safe?

Enzymes in detergents break down stains but can trigger allergies, skin irritation, or respiratory issues, especially in babies with sensitive skin. Combined with optical brighteners and surfactants, they leave residues that exacerbate eczema or developmental risks, making enzyme-free options preferable for infants.[4][5]

QHow can I avoid optical brighteners in laundry detergents?

Check labels for 'optical brightener-free,' 'no fluorescent agents,' or certifications like EPA Safer Choice. Choose plant-based, non-toxic brands without dyes, fragrances, or phosphates. Alternatives like oxygen bleach, vinegar, or baking soda achieve brightness without toxicity for baby clothes.[2][4][5]

QWhy should I use special detergent for baby clothes?

Babies have delicate, permeable skin absorbing residues from regular detergents containing optical brighteners, enzymes, dyes, and fragrances, leading to rashes, eczema, allergies, or developmental issues. Specialized, fragrance-free, dye-free formulas minimize risks from higher per-body-weight exposure and poor detoxification in infants.[5][7][8]
