Frequently asked questions

Is hc blue no. 13 safe during pregnancy?

HC Blue No.13 is a nitro‑/amino‑containing HC (hair colour) dye used in rinse/semipermanent hair products; no harmonised CLP (H360/H361) or SCCS/SCCP reproduction classification was found, and CIR lists HC ‘Blue’ dyes among ingredients reviewed as “safe as used.” However the chemical contains nitro/aromatic‑amine functionality (structural concern for metabolic activation), so I score a theoretical structural/class‑based reproductive concern only (h=1) with a theoretical mechanism (m=1). Measurable but low systemic exposure is expected from topical hair applications (evidence: product ingredient lists and CIR references). Sources: CIR quick reference and ingredient registries. (Citations: CIR quick reference; Cosmile/perflavory listing; product ingredient pages).

Is hc blue no. 13 safe while breastfeeding?

Same rationale as pregnancy: no harmonised reproduction classification or clinical human reproductive signal located, but aromatic‑amine/nitro structure creates a theoretical hazard (h=1) and theoretical mechanism (m=1). Dermal/topical hair use gives low but measurable exposure; transfer into breastmilk not demonstrated in available literature. Sources: CIR lists, ingredient/product listings; lack of ECHA harmonised classification noted.

Is hc blue no. 13 safe for baby skin?

No infant‑specific reproductive/toxicology data located. Per the requested scoring rules, infant exposure score is adult exposure +1 when measurable — here adult e=1 → baby e=2 because infant skin has higher permeability and HC Blue No.13 is used in topical hair colour formulations that can contact skin. Hazard and mechanism remain theoretical (h=1, m=1) because no infant‑specific adverse data were found. Sources: product ingredient listings and CosIng/COSMILE entries; CIR quick reference; no harmonised CLP found.
