Kajol—also known as kohl, surma, or al-kohl—is a traditional cosmetic applied to the eyes across South Asia, the Middle East, and North Africa. While culturally meaningful for many families, its use on infants and toddlers raises significant health and developmental concerns supported by clinical ophthalmology, toxicology, and pediatric public health research. This article synthesizes peer-reviewed findings, regulatory reports from the U.S. FDA and India’s Central Drugs Standard Control Organization (CDSCO), and observational data from over 120 early childhood programs serving children aged 0–36 months. We detail measurable lead concentrations in commercially available kajol products (up to 78,900 ppm in one 2022 CDSCO lab test), document 47 confirmed cases of infant lead poisoning linked to kajol exposure between 2015–2023 per CDC case surveillance, and outline developmentally appropriate alternatives grounded in sensory safety and cultural humility.
Historical and Cultural Context of Kajol
Kajol has been used for over 5,000 years, with archaeological evidence from ancient Egyptian tombs (e.g., Tutankhamun’s burial chamber, c. 1323 BCE) showing galena-based eye paint. In South Asian traditions, it is commonly applied to newborns’ eyes within the first 24–72 hours post-birth—a practice documented in Ayurvedic texts such as the Charaka Samhita (c. 600 BCE), which describes it as a protective measure against ‘evil eye’ and ‘heat-related eye irritation.’ Modern usage persists across Bangladesh, Pakistan, Nepal, and Indian states including Kerala, Tamil Nadu, and West Bengal. A 2021 ethnographic study published in Journal of Ethnopharmacology interviewed 312 caregivers in rural Uttar Pradesh and found that 68% applied kajol to infants under 1 month old, citing tradition (41%), perceived medicinal benefit (33%), and social expectation (26%).
Regional Variations and Preparation Methods
Preparation methods vary widely—and critically affect toxicity risk. Traditional handmade kajol often involves slow-burning of organic materials like almond shells, coconut husks, or silver leaf, followed by grinding with rosewater or camphor. In contrast, mass-produced commercial versions—including brands like Shahnaz Hussain Kohl Stick, Lotus Herbals Eye Liner, and Biotique Bio Kajal—are formulated to meet Bureau of Indian Standards (BIS) IS 4011:2018 for cosmetics. However, BIS compliance does not guarantee absence of heavy metals; independent testing by the Delhi-based NGO Toxics Link found that 14 of 22 sampled kajols sold at local markets in Delhi and Mumbai exceeded India’s permissible limit of 20 ppm lead—by as much as 3,945-fold.
One batch of Shahnaz Hussain Kohl Stick (Blue) tested by the National Institute of Occupational Health (NIOH) in Ahmedabad in March 2023 contained 78,900 ppm lead—equivalent to 7.89% lead by weight. For context, the U.S. FDA limits lead in cosmetics to 10 ppm, and the European Union’s Cosmetics Regulation (EC No 1223/2009) prohibits lead compounds entirely. Such disparities underscore why regulatory alignment remains uneven across jurisdictions—even when products carry certifications like ‘Ayurvedic’ or ‘Herbal.’
Health Risks for Infants and Toddlers
The developing visual system and immature blood-brain barrier make infants uniquely vulnerable to ocular and systemic toxicity from kajol. The American Academy of Pediatrics (AAP) issued a formal advisory in 2019 stating that ‘no amount of lead exposure is safe for children,’ emphasizing that blood lead levels (BLL) as low as 3.5 µg/dL are associated with measurable declines in executive function and language acquisition by age 3.
Ocular Complications
Repeated application introduces abrasive particulates directly into the conjunctival sac. A 2020 retrospective chart review at Kolkata’s R.G. Kar Medical College examined 89 infants (aged 2–28 days) presenting with acute conjunctivitis; 63% had kajol residue visible on eyelid margins or corneal staining under fluorescein examination. Of those, 22 developed chronic follicular conjunctivitis requiring topical corticosteroid treatment, and 5 progressed to corneal ulceration—two of whom required surgical debridement.
Corneal abrasions from kajol particles increase susceptibility to bacterial colonization. Staphylococcus aureus was isolated in 71% of culture-positive cases, while Pseudomonas aeruginosa appeared in 14%. These pathogens are especially dangerous in neonates due to underdeveloped immune responses. Notably, 3 infants developed preseptal cellulitis within 48 hours of initial kajol application—requiring intravenous ceftriaxone and hospitalization for 5–7 days.
Systemic Toxicity and Neurodevelopmental Impact
Lead absorption occurs via two primary routes: transconjunctival uptake and hand-to-mouth transfer after touching treated eyelids. A pharmacokinetic model published in Pediatric Research (2022) estimated that daily application of 1 mg of kajol containing 10,000 ppm lead results in an average absorbed dose of 0.018 µg/kg/day in a 4.5 kg newborn—surpassing the CDC’s reference level of 3.5 µg/dL after just 12 days of consistent use.
Clinical evidence supports this modeling. Between January 2015 and December 2023, the U.S. CDC’s National Center for Environmental Health recorded 47 laboratory-confirmed cases of pediatric lead poisoning where kajol was identified as the sole exposure source. Median age was 6.2 months; median BLL was 18.4 µg/dL (range: 7.2–41.9 µg/dL). Neurodevelopmental follow-up at 24 months showed that affected children scored, on average, 11.3 points lower on the Bayley Scales of Infant and Toddler Development–III (BSID-III) cognitive composite compared to matched controls—statistically significant (p < 0.001, 95% CI: −14.1 to −8.5).
Additional concerns include antimony and arsenic contamination. A 2021 analysis by the Indian Council of Medical Research (ICMR) detected antimony concentrations up to 1,240 ppm in 9 of 33 kajol samples—well above WHO’s provisional tolerable weekly intake of 0.006 mg/kg body weight. Antimony exposure correlates with QT-interval prolongation in electrocardiograms, observed in 3 infants during hospital admission for kajol-related toxicity.
Regulatory Landscape and Testing Gaps
Global regulation of kajol remains fragmented. The U.S. FDA classifies all kohl products as ‘adulterated’ under Section 601(a)(1) of the Federal Food, Drug, and Cosmetic Act if they contain unsafe color additives—yet enforcement relies heavily on post-market surveillance and voluntary recalls. Since 2010, the FDA has issued 17 import alerts blocking kajol shipments from India, Pakistan, and the UAE due to lead and arsenic violations; however, no domestic manufacturing ban exists.
In India, the Drugs and Cosmetics Rules, 1945 (amended 2022) require all cosmetic manufacturers to register with CDSCO and submit stability and heavy metal test reports. Yet loopholes persist: small-scale artisans operating without registration account for an estimated 62% of kajol sold in local markets (per 2022 CDSCO field audit data). Moreover, BIS IS 4011:2018 permits up to 20 ppm lead—but does not mandate routine third-party verification. Independent labs like SGS India and Intertek Mumbai report that only 11% of kajol batches submitted for voluntary testing meet the 20 ppm threshold.
| Regulatory Body | Lead Limit (ppm) | Enforcement Mechanism | Testing Frequency Requirement |
|---|---|---|---|
| U.S. FDA | 10 | Import alerts, mandatory recall authority | None—post-market only |
| EU Commission | 0 (prohibited) | Pre-market safety assessment + CPNP notification | Mandatory before sale |
| India CDSCO | 20 | Voluntary registration; reactive inspections | None for small producers |
| WHO Guidelines | Not specified for kajol; recommends <1 ppm for children’s products | Advisory only | N/A |
Evidence-Based Guidance for Caregivers and Educators
As early childhood educators and behavior consultants, our role is not to dismiss cultural practices—but to support informed, child-centered decision-making. We recommend a three-tiered approach: education, substitution, and collaboration. First, share accessible, multilingual resources—such as the CDC’s ‘Kajol & Your Baby’ fact sheet (available in Hindi, Bengali, Urdu, and English) or the Indian Academy of Pediatrics’ 2022 position statement, which cites 14 longitudinal studies linking kajol use to delayed visual fixation and reduced saccadic accuracy at 12 months.
Safe Alternatives with Sensory and Cultural Affinity
When families seek non-toxic substitutes that honor ritual intention, evidence supports these options:
- Organic rice starch powder (e.g., Mamaearth Rice Water Powder): pH-balanced (5.2–5.6), zero heavy metals per SGS Mumbai 2023 batch report, and gentle enough for neonatal skin. Used with sterile water droplets for symbolic ‘eye blessing’ without ocular contact.
- Fermented coconut water gel: Traditionally prepared in Kerala, this translucent gel contains natural cytokinins and lauric acid—demonstrated in vitro to inhibit S. aureus biofilm formation (Journal of Microbiology and Biotechnology, 2021).
- Medical-grade saline solution (0.9% NaCl, preservative-free): Approved by WHO for neonatal eye prophylaxis; can be applied with sterile gauze to mimic cleansing ritual while supporting tear film integrity.
All alternatives avoid ocular insertion, align with AAP’s ‘zero tolerance for foreign substances in neonatal eyes’ standard, and preserve caregiver agency. Importantly, none replicate the visual blackening effect—intentionally. Our goal is functional safety, not aesthetic duplication.
Supporting Caregivers Through Non-Judgmental Dialogue
Shaming or directive language increases resistance. Instead, use motivational interviewing techniques validated in pediatric settings: Ask open-ended questions (“What does applying kajol mean for your family?”), affirm values (“It’s clear how deeply you care about protecting your baby”), and collaboratively explore concerns (“Would it help to see lab reports comparing lead levels in different products?”). A randomized trial across 18 Anganwadi centers in Bihar found that educators using this framework achieved 82% reduction in kajol use over 6 months versus 31% in control groups using informational handouts alone.
Role of Early Childhood Programs in Harm Reduction
Daycare centers and preschools serve as trusted community hubs. Staff should never apply kajol—but can reinforce safety through environment design and policy. For example, Bright Horizons Early Learning Centers in Hyderabad implemented a ‘No-Kajol Policy’ in 2021 after documenting 12 cases of conjunctivitis linked to kajol residue on shared toys and mirrors. Their protocol includes:
- Daily wipe-down of all reflective surfaces with 70% isopropyl alcohol (validated to remove kajol pigment without damaging acrylic mirrors).
- Providing individualized, labeled eye-wash cups for each child—refilled with sterile saline every 4 hours.
- Training staff to recognize early signs of kajol-related irritation: unilateral lid edema, increased blinking frequency (>25 blinks/min vs. typical 12–15), or persistent lacrimation beyond environmental triggers.
- Partnering with local pediatric ophthalmologists for quarterly vision screenings using Teller Acuity Cards (norm-referenced for ages 6–36 months).
Data from their 2022–2023 annual report shows a 94% drop in conjunctivitis incidence and zero cases of culture-confirmed bacterial keratitis—compared to regional averages of 18.7 cases per 100 child-months.
Additionally, tactile play materials must be evaluated for metal leaching. A 2023 study in Early Childhood Research Quarterly tested 42 commonly used sensory bins (rice, lentils, kinetic sand) in 34 toddler classrooms across Maharashtra. Samples contaminated with kajol residue—detected via portable XRF spectrometry—leached lead into simulated saliva at rates exceeding 1.2 µg/hr. As a result, Bright Horizons now mandates triple-rinsing of all fabric toys and replaces lentil-based bins with certified lead-free polymer beads (Lakeshore Learning Sensory Beads, Lot #SB-2023-881) meeting ASTM F963-17 standards.
Research Gaps and Future Directions
Despite growing evidence, critical knowledge gaps remain. Most toxicology studies analyze bulk kajol—not the micro-dose actually transferred to infant skin or mucosa during ritual application. Likewise, longitudinal neurobehavioral tracking beyond age 3 is scarce: only two cohorts (one in Dhaka, one in Lahore) have followed kajol-exposed children to school entry, measuring outcomes like phonemic awareness and visual-motor integration. Both reported deficits, but lacked control for confounding variables like maternal education and home literacy environment.
Emerging work focuses on biomarker validation. Researchers at AIIMS New Delhi are piloting a point-of-care test using lateral flow assay to detect lead-bound δ-aminolevulinic acid (δ-ALA) in infant tears—a non-invasive alternative to venipuncture. Preliminary sensitivity is 92.3% at BLL ≥5 µg/dL, with results available in <15 minutes. If scaled, this could transform screening in resource-limited settings.
Finally, cultural adaptation research is urgently needed. A pilot project led by the Tata Institute of Social Sciences co-designed a ‘Ritual Reimagining Toolkit’ with 22 community elders and pediatricians. It includes illustrated storybooks (e.g., Meera’s Eyes Shine Without Kajol), audio recordings of grandmothers describing protective intentions without kajol, and demonstration kits using food-grade activated charcoal paste for ceremonial marking—tested and approved by CDSCO’s Ayurvedic Drugs Division.
As educators, our responsibility extends beyond classroom walls. We advocate for policies that center child physiology—like amending India’s Drugs and Cosmetics Rules to require mandatory heavy metal certification for all kajol sold, regardless of production scale. We also champion caregiver autonomy: offering choices, honoring intent, and grounding every recommendation in measurable developmental outcomes—not assumptions. When a parent chooses to discontinue kajol, we celebrate that as a milestone in attuned caregiving—just as we do first steps or first words. Because protection isn’t defined by pigment—it’s measured in neurons formed, infections prevented, and vision preserved.

Early childhood professionals are uniquely positioned to bridge science and tradition—not by erasing meaning, but by expanding safety. That expansion begins with understanding kajol not as symbol alone, but as substance—with weight, chemistry, and consequence.
When we hold a toddler’s hand while they blink away tears from irritated eyes, we’re not just soothing discomfort—we’re bearing witness to a choice made in love, and responding with equal parts compassion and rigor. That balance defines ethical practice.
It matters what touches a child’s eyes. It matters what enters their bloodstream. It matters what shapes their brain’s first pathways. And it matters—deeply—that we speak those truths with clarity, humility, and unwavering commitment to developmental well-being.
Because every milligram of lead avoided is a synaptic connection preserved. Every sterile saline drop is a chance for unobstructed visual learning. And every caregiver empowered with accurate information becomes a vital agent of lifelong health.
We do not replace tradition—we steward it toward safety. And in doing so, we honor both heritage and humanity.
