Is Coal tar safe for babies and kids?
High risk for kidsInfants are more vulnerable to Coal tar than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.
What is coal tar?
Also known as: Alphosyl, Capasal, Clinitar, Coal tar,colloidal.
- CAS number
- 8007-45-2
Risk for babies
High riskInfants are more vulnerable to Coal tar than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.
Neonates and infants up to 12 months have incomplete blood-brain barrier development, immature Phase I/II metabolic enzymes (particularly CYP3A4, UGT1A1), and higher gastrointestinal permeability. Equivalent doses produce higher internal concentrations and longer residence times.
Risk for pregnant and nursing people
Elevated riskPregnancy alters the metabolism and distribution of Coal tar, potentially increasing fetal exposure. The developing embryo/fetus is vulnerable during organogenesis (weeks 3-8) and neurological development. Placental transfer should be assumed.
Suspected reproductive toxicant (GHS H361) or suspected endocrine disruptor. Precautionary approach warranted. Animal studies or limited human data suggest developmental toxicity potential.
Regulatory consensus
10 regulatory and scientific bodies have classified Coal tar. The classifications differ — that's the data.
| Agency | Year | Classification | Notes |
|---|---|---|---|
| IARC | 2012 | Group 1 (carcinogenic to humans) | IARC Monograph 100F (2012). Coal tar (crude) and coal tar pitch are IARC Group 1 based on sufficient evidence in both humans and animals. Primary cancer sites: skin (squamous cell carcinoma from topical exposure; historically the first occupationally identified carcinogen — Percivall Pott's 1775 chimney sweep scrotal cancer observation), lung (from inhalation of coal tar fume in occupational settings), and bladder. Coal tar consists of thousands of PAH compounds including benzo[a]pyrene (IARC Group 1, hq-c-org-000029), dibenz[a,h]anthracene (Group 1), naphthalene (Group 2B), and many other PAHs and phenolic compounds. Consumer products containing coal tar (0.5–5% coal tar in dandruff/psoriasis shampoos and topical treatments) are approved by FDA as OTC drugs but carry lower concentrations of carcinogenic PAHs than industrial-grade coal tar; nonetheless, dermal carcinogen absorption from therapeutic coal tar preparations is documented. |
| US EPA | 2008 | Known/likely human carcinogen (coal tar pitch volatiles classified as known) | US EPA IRIS: Coal tar pitch volatiles listed as known human carcinogens based on occupational epidemiology (aluminum production, coke oven workers, roofing). EPA has also flagged coal tar-based sealants used on parking lots and driveways as a source of PAH runoff into urban waterways, with associated aquatic toxicity concerns. The EPA's Stormwater Program has published guidance on coal tar sealcoat as an environmental concern for urban watersheds. |
| EPA CTX / NTP RoC | — | Known Human Carcinogen | |
| EPA CTX / IARC | — | Group 1 - Carcinogenic to humans | |
| EPA CTX / Genetox | — | Genotoxicity: positive (Ames: positive, 3 positive / 0 negative reports) | |
| EPA CTX / Genetox | — | Genotoxicity: positive (Ames: positive, 3 positive / 0 negative reports) | |
| EPA CTX / Skin-Eye | — | Skin Sensitization: Skin sensitisation - category 1 (score: high) | |
| EPA CTX / Skin-Eye | — | Eye Irritation: Category 1 (score: very high) | |
| EPA CTX / Skin-Eye | — | Skin Irritation: Category 3 (score: moderate) | |
| EPA CTX / Skin-Eye | — | Skin Sensitization: Category 1 (score: high) |
Regulators apply different standards of evidence — animal-data weighting, exposure-pattern assumptions, epidemiological power thresholds — which is why two scientific bodies can review the same data and reach different conclusions. The disagreement is the data.

Frequently asked questions
Is coal tar safe for kids?
Infants are more vulnerable to Coal tar than children or adults due to immature hepatic/renal clearance, higher intake-to-body-weight ratio, rapid organ development, and increased gastrointestinal absorption.
What products contain coal tar?
Coal tar appears in: Manufacturing plants (Industrial facilities); Chemical storage areas (Industrial facilities); Factories (Occupational environments); Warehouses (Occupational environments).
What should I do if my child is exposed to coal tar?
Minimize infant exposure through source control. For breastfeeding mothers: reduce maternal exposure. For formula-fed infants: use certified low-migration bottles and verified water sources. Consult pediatrician regarding any concerns.
Why do regulators disagree about coal tar?
Coal tar has been classified by 10 agencies including IARC, US EPA, EPA CTX / NTP RoC, EPA CTX / IARC, EPA CTX / Genetox, with differing conclusions. Regulators apply different standards of evidence (animal data weighting, exposure-pattern assumptions, epidemiological power thresholds), which is why two scientific bodies can review the same data and reach different conclusions.
