Your baby's skin is not a smaller version of yours. It is thinner, more permeable, and covers a much larger surface area relative to body weight. What sits on that skin - for hours at a time, on the most sensitive areas of the body - gets absorbed at a higher rate than it would in an adult. That is why the ingredient standard for baby skincare matters more than it does for anything you put on yourself.

The EU operates the strictest cosmetics regulation in the world. Under Regulation (EC) No 1223/2009, over 1,600 substances are banned or restricted from cosmetics entirely - compared to around 11 under US FDA oversight. The gap is not because European babies are more delicate. It is because the EU applies a precautionary standard: restrict first, prove safety before permitting. The US permits first, restricts after harm is demonstrated.

The 12 to know

01
Parabens
Look for: methylparaben, ethylparaben, propylparaben, butylparaben, isobutylparaben
Parabens are preservatives used to extend shelf life. They are also known endocrine disruptors - meaning they mimic oestrogen in the body. The EU has banned propylparaben and butylparaben in products used in the nappy area of children under 3, because of the higher absorption rate of thin, sensitive skin in that zone. They restrict all parabens to strict concentration limits across baby products. Many US baby products still contain them with no restriction.

02
Mineral oil
Look for: paraffinum liquidum, petrolatum, petroleum jelly, paraffin wax
Mineral oil is a byproduct of petroleum refining. It creates an occlusive barrier on skin - which feels moisturising but actually prevents the skin from breathing or regulating itself. More significantly, certain grades of mineral oil (specifically MOAH - mineral oil aromatic hydrocarbons) are classified as potentially carcinogenic by the EU's Scientific Committee on Consumer Safety. The EU requires cosmetics-grade mineral oil to be highly refined and restricts impure grades. Products using insufficiently refined mineral oil would not be compliant with EU standards - which is one reason EU-certified products are the safer reference point.
EU: Restricted - purity standards required, impure grades banned Source: EU Cosmetics Regulation 1223/2009, Annex II (impure mineral oils prohibited)
03
Synthetic fragrance
Look for: parfum, fragrance, aroma
The word "fragrance" or "parfum" on a label can represent a blend of up to several hundred individual chemicals - none of which have to be individually disclosed. This is a legal loophole used in both the US and EU, though the EU requires the individual listing of 26 specific fragrance allergens if present above certain thresholds. Many synthetic fragrance components are known sensitisers and allergens. For a baby whose immune system and skin barrier are still developing, fragrance is one of the most common causes of contact dermatitis. The EU's ongoing fragrance allergen labelling reforms are expanding the list of substances that must be named. The safest position is fragrance-free entirely.
EU: 26 allergens must be individually labelled - reforms ongoing Source: EU Cosmetics Regulation 1223/2009, Annex III
04
Phenoxyethanol
Look for: phenoxyethanol, 2-phenoxyethanol
Phenoxyethanol is a preservative used as a paraben alternative - and often marketed as such. The EU restricts it to a maximum of 1% in all cosmetics and has specifically warned against its use in products applied to the nappy area or on the chest of breastfeeding women. In 2008, the US FDA warned against a nipple cream containing phenoxyethanol after reports that it depressed the central nervous system in breastfed infants. The French agency ANSM subsequently issued its own precautionary ruling in 2019 requiring that leave-on products containing phenoxyethanol carry a warning that they must not be used on the nappy area of children under 3. It is not banned under EU law, but the regulatory trend is clear.

05
Formaldehyde and formaldehyde releasers
Look for: DMDM hydantoin, quaternium-15, imidazolidinyl urea, diazolidinyl urea, bronopol
Formaldehyde itself is banned in EU cosmetics above trace levels. But formaldehyde releasers - preservatives that slowly release formaldehyde over time - are common in baby shampoos, wipes, and lotions. Formaldehyde is a known human carcinogen. The EU requires that if a product contains formaldehyde releasers and the product releases more than 0.05% formaldehyde, the label must state "contains formaldehyde." Many products containing these ingredients never trigger that threshold in testing but still release low-level formaldehyde over the product's life. The EU is progressively tightening limits on releasers.
EU: Formaldehyde banned above trace levels - releasers must be labelled Source: EU Cosmetics Regulation 1223/2009, Annex II entry 5
06
PEGs (polyethylene glycols)
Look for: PEG followed by a number (PEG-40, PEG-100, etc.), also ceteareth, polysorbate
PEGs are used as emulsifiers, penetration enhancers, and humectants. The concern is twofold. First, their manufacturing process can leave residues of ethylene oxide and 1,4-dioxane - both of which are classified as carcinogens. Second, as penetration enhancers, PEGs can increase the absorption rate of other ingredients through the skin - which on a newborn is already significantly higher than in an adult. The EU restricts certain PEG compounds and requires purity standards. Certified organic cosmetics exclude them entirely.
EU: Restricted - manufacturing impurities classified as carcinogens Source: EU Cosmetics Regulation 1223/2009, Annex II
07
Methylisothiazolinone (MI) and Methylchloroisothiazolinone (MCI)
Look for: methylisothiazolinone, methylchloroisothiazolinone, MIT, CMIT/MIT
MI and MCI are preservatives that the EU's Scientific Committee on Consumer Safety (SCCS) concluded have no safe concentration in leave-on cosmetics due to their extreme sensitising potential. MI is now banned from all leave-on cosmetics in the EU. MCI/MI mixture is permitted only in rinse-off products at very low concentrations. Despite this, products containing MI still appear in US and some UK baby ranges. The SCCS was explicit: there is no safe level for leave-on use.

08
Phthalates
Look for: often hidden under "fragrance" - also dibutyl phthalate (DBP), diethyl phthalate (DEP)
Phthalates are plasticisers used in fragrance fixatives and nail products. Several are banned across EU cosmetics as endocrine disruptors - substances that interfere with hormonal development. Because some phthalates have historically been used as fragrance fixatives, and because fragrance blends do not require full ingredient disclosure, the fragrance-free choice eliminates a potential route of exposure. You cannot know what is in a fragrance blend - and documented endocrine disruptors are among the possible components.

09
Sodium lauryl sulphate (SLS) and sodium laureth sulphate (SLES)
Look for: sodium lauryl sulfate, sodium laureth sulfate, SLS, SLES
SLS and SLES are surfactants - the foaming agents in shampoos, body washes, and bubble baths. SLS is a known skin irritant that strips the skin's natural lipid barrier. In babies, whose barrier is thinner and still developing, repeated use of SLS-containing products can disrupt the microbiome of the skin and increase transepidermal water loss. SLES is milder but its manufacturing can leave 1,4-dioxane residues - the same carcinogen found in PEG compounds. Neither is banned in the EU, but both are avoided entirely in certified organic baby cosmetics.

10
Retinoids (vitamin A derivatives)
Look for: retinol, retinyl acetate, retinyl palmitate, retinoic acid
Retinoids are used in anti-ageing skincare but also appear in some baby and child products as vitamin A sources. In 2024, the EU introduced strict new concentration limits for retinol and retinyl derivatives in leave-on and body products - specifically because of cumulative vitamin A exposure concerns. Vitamin A toxicity in infants is a real clinical risk. The EU requires that all products containing retinoids carry a label warning. They are not banned, but the EU's position is clear: these concentrations should be minimised, especially in products for young children.
EU: Restricted with mandatory labelling - new limits introduced 2024 Source: EU Commission Regulation 2024/996
11
Triclosan and triclocarban
Look for: triclosan, triclocarban, 5-chloro-2-(2,4-dichlorophenoxy)phenol
Triclosan is an antibacterial agent that was widely used in baby products until its risks became clear. It is an endocrine disruptor shown to affect thyroid hormone levels and has been linked to antibiotic resistance development. The EU has banned triclosan from cosmetics. The US FDA also banned it from hand soaps in 2017 but it still appears in some products. Triclocarban, used similarly, faces equivalent restrictions. Both are included here because they still appear in products marketed as "antibacterial" for babies in less regulated markets.
EU: Banned from cosmetics Source: ECHA Cosmetics Annex II - Triclosan entry 1369
12
Oxybenzone and chemical UV filters
Look for: benzophenone-3, oxybenzone, octinoxate, homosalate, octisalate
Chemical UV filters absorb UV radiation but penetrate the skin to do so - which means they enter the bloodstream. Several are endocrine disruptors. The EU restricts their maximum concentrations and has banned several entirely, while the FDA is still reviewing their safety. For babies under 6 months, most dermatologists recommend avoiding sunscreen entirely and using shade and clothing instead. For older babies, mineral UV filters - zinc oxide and titanium dioxide - sit on top of the skin rather than penetrating it, and are the recommended alternative in both EU and US guidance.

What to do with all of this

Reading an ingredient list on a baby skincare product while standing in a shop is not realistic. Here is the shortcut version: look for certification. Products certified under COSMOS Organic, NATRUE, or Ecocert have been independently verified against ingredient standards that exclude the vast majority of the above. They are not perfect - certification does not guarantee that every ingredient is beneficial - but they exclude the most problematic ones systematically.

Fragrance-free is the single most useful filter if you are not buying certified organic. Most of the hidden ingredients on this list - phthalates, certain preservatives, sensitising compounds - enter baby products through the fragrance blend. Fragrance-free removes that entire category of risk.

A practical label-reading rule

The shorter the ingredient list, the lower the risk. A baby balm with four ingredients - shea butter, calendula extract, beeswax, vitamin E - has fewer places for something problematic to hide than a lotion with 28. Complexity in baby skincare is rarely a feature. It is usually a cost and shelf-life decision.

The EU standard is the reference because it is the strictest globally verified benchmark available. That does not mean every non-EU product is dangerous - it means that when a product meets EU standards, the scrutiny behind that approval is the highest available. For a baby whose skin will be absorbing whatever you apply to it, the margin for benefit of the doubt is narrow.

The short version

Avoid: parabens, mineral oil, synthetic fragrance, phenoxyethanol, formaldehyde releasers, PEGs, MI/MCI, phthalates, SLS/SLES, retinoids in leave-on products, triclosan, and chemical UV filters in the first six months.

Look for: COSMOS Organic, NATRUE, or Ecocert certified. Fragrance-free. Short ingredient lists with recognisable names. Mineral UV filters (zinc oxide, titanium dioxide) for sun protection after 6 months.

The one sentence version: if you would not be comfortable with it on your own most sensitive skin for 24 hours a day, it should not be on your baby's.

"We apply the same ingredient scrutiny to baby skincare that we apply to formula - because the same logic holds. What goes on the skin matters as much as what goes in the bottle."
