Frequently asked questions

Is aminoguanidine bicarbonate safe during pregnancy?

Harmonised EU classification for aminoguanidinium hydrogen carbonate (CAS 2582-30-1) lists Reproductive toxicity Category 1B (H360), which indicates presumed human reproductive toxicity (ECHA). Animal/experimental studies with aminoguanidine report fetal developmental effects in rodents (fetal toxicity, growth effects), and aminoguanidine is a biologically active iNOS inhibitor affecting nitric oxide pathways relevant to pregnancy, supporting a demonstrated mechanism. Topical cosmetic exposure would likely give low but measurable systemic exposure for adults (no data showing negligible/permanent non-absorption). ([echa.europa.eu](https://echa.europa.eu/brief-profile/-/briefprofile/100.018.143?utm_source=openai))

Is aminoguanidine bicarbonate safe while breastfeeding?

Because the substance has an EU harmonised classification as Repr.1B (H360), the hazard score for breastfeeding is aligned with pregnancy (h=3). The mechanism (iNOS inhibition; demonstrated biological activity) supports potential effects on reproductive/offspring endpoints; no specific lactation transfer data were found, so adult topical exposure is assumed to give low but measurable systemic levels absent formulation-specific data.

Is aminoguanidine bicarbonate safe for baby skin?

Harmonised Repr.1B classification (H360) applies irrespective of age; therefore hazard remains h=3 for infant skin contact. Mechanistic evidence (aminoguanidine biological activity) is applicable. Exposure rating is increased by +1 for baby skin because aminoguanidine is a small, water‑soluble molecule with measurable absorption potential; infant skin has higher absorption per weight, so exposure is likely moderate relative to adults in the absence of specific dermal absorption/formulation data.
