Baby skin is thinner, loses water faster and reacts more readily than adult skin, and parents read labels closely. Baby care product testing therefore goes further than for adult cosmetics: the safety assessor must pay special attention to infants, microbiological limits are stricter and claims such as “gentle” or “hypoallergenic” need real evidence. This guide explains what a baby lotion, wash, wipe or nappy cream usually needs before it is sold in the EU.

The short answer
A baby product is a cosmetic under Regulation (EC) No 1223/2009 and needs a CPSR signed by a qualified safety assessor, a product information file and a CPNP notification. The regulation asks the assessor to give special consideration to products intended for children under three years of age. In practice this means a careful ingredient review, stricter microbiological quality, solid preservation data from a challenge test, stability data, and evidence for any gentleness or tolerance claims, often from a patch test.
What counts as a baby care product?
Cosmetics for babies and young children include shampoos and washes, bath products, lotions, oils, nappy creams, wipes, sun protection and powders. The EU does not have a separate regulation for them; the same Cosmetics Regulation applies, with extra attention to the vulnerable user. The label must make the intended user clear, because the assessor evaluates safety for the stated age group. If a product is meant for newborns, say so, since newborn skin is the most sensitive case.

Why the safety assessment is stricter
The assessor works from exposure. For infants, the relevant factors differ from adults:
- A higher skin surface area compared to body weight, so a given amount of a substance gives a relatively higher systemic dose.
- A less mature skin barrier, especially in the first months, which can let more substances through.
- Application to broken or irritated skin, such as in the nappy area.
- Possible contact with mouth and eyes.
- Frequent, repeated use, sometimes several times per day.
The assessor therefore applies more cautious margins of safety and may recommend simpler formulas. The Scientific Committee on Consumer Safety (SCCS) publishes guidance on how to assess these exposures, and assessors use it as their reference.
Ingredient choices that matter
Several rules are especially relevant for baby products:
- Preservatives. Some preservatives have specific conditions in the Cosmetics Regulation. For example, certain parabens may not be used in leave-on products intended for the nappy area of children under three. Check Annex V for the preservatives you plan to use.
- Fragrance and essential oils. Many allergens come from fragrance. Many baby brands choose fragrance-free formulas or keep fragrance levels very low, and the labelling of declared allergens was extended by Regulation (EU) 2023/1545.
- Colourants. Only permitted colourants may be used, and many brands avoid colour altogether in baby products.
- Active ingredients and plant extracts. Essential oils and strongly active botanicals may be inappropriate for infants and need careful justification.
Your assessor will identify what is acceptable. Do not assume that an ingredient that is safe in an adult product is automatically acceptable for babies.
Microbiological quality: tighter limits
Products for children under three, like products for the eye area and mucous membranes, are usually held to stricter microbiological limits than other cosmetics. Guidance based on ISO 17516 and SCCS notes commonly applies a limit of 100 colony-forming units per gram or millilitre for total aerobic bacteria, and none of the specified pathogens, in these categories. The exact requirement should be confirmed with your assessor. A microbiological specifications test on the finished product, done about 5 days after we receive samples, shows that your production hygiene meets these expectations.

Preservation: the challenge test
Many baby products are water-based: wipes, lotions, washes and shampoos. Wet wipes are a particularly demanding case, because they are opened repeatedly and left in warm bathrooms and changing bags. A challenge test challenges the product with five reference microorganisms over 28 days, following ISO 11930:2019 or USP 51, and shows whether the preservative system protects the product. Because baby products are used by a vulnerable group, reduced preservation is not an option to accept lightly. If a product fails, the formula needs to be adjusted and retested.
Stability and packaging
A stability and compatibility test shows how the product behaves over time: appearance, odour, viscosity, pH and separation. For baby products, packaging matters too. Pump dispensers, tubes and wipe packs can change what is in contact with the formula, and a test in the final packaging supports the shelf life or period-after-opening symbol on the label. Nappy creams, which often contain high levels of oils and zinc oxide, deserve particular attention for texture over temperature changes.
What changes by product type
Wipes, washes and lotions are water-based, so preservation and microbiological quality come first. Nappy creams and balms are oil-rich or anhydrous, so stability, texture and the choice of skin-contact ingredients matter most. Baby shampoos are rinsed off but can reach the eyes, so mildness and pH deserve attention. Sun protection for babies is a special case with its own rules for UV filters and SPF proof. Whatever the product, the assessor needs the full formula, the intended age and the test reports together.

Patch tests and claims
Parents trust phrases like “dermatologically tested”, “hypoallergenic”, “gentle” and “suitable for sensitive skin”. The Claims Regulation (EU) No 655/2013 says claims must be truthful, supported by evidence and not misleading. A single 48-hour occlusive patch test, performed on adult volunteers, shows the skin tolerance of the formula and provides the basis for such claims. Studies involving infants are a different matter, need ethical approval and are done by specialised centres. “Hypoallergenic” does not mean allergy-free, so avoid wording that suggests a guarantee. Medical claims such as “treats eczema” are not allowed on cosmetics.
A practical checklist
- Define the age group and write it on the label (for example “from birth”).
- Keep the formula as simple as practical and review each ingredient with your assessor.
- Run a microbiological specifications test and a challenge test on the final formula.
- Run a stability test in the final packaging.
- Add a patch test if you use tolerance or “sensitive skin” claims.
- Have the CPSR signed, notify in the CPNP and check the label wording.

Frequently asked questions
Is there a separate law for baby cosmetics in the EU?
No. Baby products fall under the general Cosmetics Regulation, but the safety assessor must give special consideration to products for children under three years of age.
Can I call my product “hypoallergenic”?
Only if you can support it with evidence, such as a patch test and a careful formula review. The term should not suggest that an allergic reaction is impossible.
Do baby wipes need a challenge test?
Almost always, yes. Wipes are water-based and used repeatedly, so proof that the preservative system works is essential.
Key takeaways
- Baby products follow the standard Cosmetics Regulation, with extra scrutiny of ingredients and exposure.
- Expect stricter microbiological limits and solid preservation data.
- Claims such as “gentle” and “hypoallergenic” need evidence, usually a patch test.
- Define the age group clearly and test the final formula in its final packaging.
