Children's skin is thinner, their barriers less developed, their sensitivity far greater.
In the quiet routines of early parenthood — the dusting of powder, the scented wipe, the colorful bath toy — a Hyderabad oncologist finds cause for gentle but serious reflection. Dr. Arrjun Sankaran warns that children's thinner skin and developing systems absorb chemicals far more readily than adults, making many trusted nursery staples a source of unintended exposure to phthalates, endocrine disruptors, and formaldehyde-releasing agents. His counsel is not alarm but awareness: that the smallest choices made in a child's earliest years carry a weight parents deserve to understand.
- Children's bodies are not small adult bodies — thinner skin and immature barriers mean chemicals from everyday products absorb faster, deeper, and with greater developmental consequence.
- Products marketed as safe — BPA-free bottles, scented wipes, talcum powder — may still leach microplastics, release harmful compounds when heated, or deposit endocrine-disrupting substances on delicate skin with every use.
- The cumulative pattern is the danger: repeated daily contact with fragranced lotions, chemical sunscreens, and plastic feeding bottles creates a slow, invisible accumulation of exposure across months and years.
- Sankaran is urging a practical pivot — mineral sunscreens over chemical ones, unscented wipes over fragranced, glass or stainless steel over degrading plastic — small substitutions with meaningful long-term impact.
- The medical community is increasingly focused on the nursery as a site of preventable risk, with childhood endocrine disruption now linked to developmental concerns that may not surface until years later.
The shelves of a typical nursery — talcum powder, plastic bottles, scented wipes, squeaky bath toys — represent what most parents take to be safety. Dr. Arrjun Sankaran, an oncologist based in Hyderabad, sees something more complicated. Children's skin is thinner than adults', their chemical barriers less developed, their sensitivity to synthetic compounds far greater. What feels protective may be quietly introducing substances a young body was never meant to encounter.
Talcum powder, Sankaran notes, carries longstanding contamination concerns and should be avoided entirely on genital areas and near the nose. Plastic feeding bottles — even those labeled BPA-, BPS-, or BPF-free — present a different problem: not their initial composition, but their degradation over time. Each sterilization cycle breaks the plastic down incrementally, allowing chemicals and microplastics to migrate into milk or formula across months of daily use.
Sunscreen is its own paradox. Chemical formulas widely available in stores contain endocrine-disrupting compounds; mineral alternatives using zinc oxide or titanium dioxide offer equivalent UV protection without hormonal interference. For children under three, whose skin absorbs substances especially quickly, the distinction matters most.
Fragranced products extend the concern further. Bath toys release phthalates more readily in warm water. Scented wipes, used multiple times daily on sensitive skin, may contain polyethylene glycols and residual ethylene oxide. Lotions and powders with added fragrance often rely on formaldehyde-releasing preservatives. At doses that would barely register in an adult, these substances can interfere with a child's developing endocrine system.
Sankaran's message is not one of fear but of informed substitution. Mineral over chemical sunscreen. Unscented over fragranced wipes. Water and cloth over powder. The nursery need not be stripped bare — but the small, deliberate choices made in these earliest years can meaningfully reduce a child's unnecessary chemical burden.
The shelf of a typical nursery holds what most parents assume to be safe: talcum powder for diaper rash, plastic feeding bottles marked BPA-free, colorful bath toys, scented wipes. But according to Dr. Arrjun Sankaran, an oncologist based in Hyderabad, many of these everyday items carry a hidden cost. Children's bodies process chemicals differently than adults do. Their skin is thinner, their barriers less developed, their sensitivity to fragrances and synthetic compounds far greater. What feels protective to a parent—a dusting of powder, a convenient wipe—may be introducing substances a child's body simply doesn't need to encounter.
Talcum powder has long carried contamination concerns, Sankaran notes, and the risk is particularly acute in sensitive areas. The oncologist advises parents to skip it entirely on genital regions and around the nose. The same caution applies to plastic feeding bottles, even those marketed as free of BPA, BPS, or BPF. The problem isn't the initial material but what happens over time. Each sterilization cycle degrades the plastic incrementally. Chemicals and microplastics gradually migrate into the milk or formula a child drinks, a slow leaching that accumulates across months of daily use.
Sunscreen presents a similar paradox. Protecting skin from UV damage matters, but chemical sunscreens—the kind most readily available—contain compounds that act as endocrine disruptors. Mineral-based alternatives using zinc oxide or titanium dioxide offer gentler protection without the hormonal interference. For children under three, the stakes are higher still. Their skin is substantially thinner than an adult's, meaning absorption happens faster and deeper.
Fragranced products pose a broader threat. Bath toys that squeak and float, seemingly innocent fixtures of childhood, often contain phthalates. When placed in warm water, these chemicals leach more readily. The combination of heat, moisture, and repeated contact accelerates exposure. Scented baby wipes, convenient for quick cleanups, may contain polyethylene glycols, fragrances, and residual ethylene oxide. Used multiple times daily on delicate skin, they create a pattern of repeated chemical contact that can trigger irritation or sensitivity over time. Unscented wipes or simple cotton cloths dampened with water accomplish the same task without the additives.
The broader category of fragranced items—lotions, powders, oils—all carry similar risks. Phthalates and formaldehyde-releasing agents are common ingredients, chosen for their preservative or scent-fixing properties. For developing bodies, these substances interfere with endocrine function at doses that would barely register in adult exposure. Sankaran's message isn't alarmist. Parents need not purge every product from the house or live in fear of ordinary items. What matters is mindfulness: reading labels, understanding what ingredients do, and choosing alternatives where they exist. Mineral sunscreen instead of chemical. Unscented wipes instead of fragranced. Water and cloth instead of powder. Small shifts in what enters a child's environment during these formative years can meaningfully reduce unnecessary chemical exposure.

Why does a child's skin absorb chemicals so much more readily than an adult's?
It's a matter of thickness and development. A young child's skin barrier is still forming—it's literally thinner, more permeable. The protective mechanisms adults rely on haven't fully developed yet. That means anything applied to or near the skin penetrates more deeply and stays in the system longer.
So when a parent uses talcum powder, they're not just applying powder. They're introducing something that can travel deeper into the body.
Exactly. And talcum powder specifically has a history of contamination issues. But the broader point applies to almost everything on that shelf—scented wipes, fragranced lotions, even those "safe" plastic bottles. Each one is a small exposure that compounds over time.
The plastic bottle issue surprised me. It's marked BPA-free. Isn't that enough?
The initial material might be safe, but it degrades. Every time you sterilize it—heat, pressure, repeated cycles—the plastic breaks down slightly. Chemicals and microplastics migrate into the milk. It's not a single exposure; it's daily, across months. That accumulation matters.
What about sunscreen? That seems like something you'd want to use.
You do want sun protection. The distinction is chemical versus mineral. Chemical sunscreens absorb into the skin and work by converting UV rays into heat. Many contain endocrine disruptors—compounds that interfere with hormonal development. Mineral sunscreens sit on top of the skin and reflect rays. Zinc oxide and titanium dioxide do the job without the hormonal risk.
Is the concern that parents are being deceived, or that they simply don't know?
Mostly the latter. These products aren't hidden or banned. They're on shelves, marketed as safe, convenient. Parents aren't being reckless—they're trusting what they're sold. The issue is that "safe for adults" doesn't mean "safe for children." A fragrance that causes mild irritation in an adult might trigger sensitivity in a child. An endocrine disruptor at low doses in an adult might affect development in a child.
So what's the practical takeaway?
Don't panic and don't overhaul everything overnight. But start paying attention. Read labels. When you have a choice, pick unscented over scented, mineral over chemical, simple over complex. Water and cloth instead of wipes when possible. Small shifts add up.
