Frequently asked questions

Is ammonium nonoxynol-30 sulfate safe during pregnancy?

No EU Cosmetic Annex II ban or harmonised CLP reproductive H‑codes were identified for ammonium nonoxynol‑30 sulfate itself, but it is a nonylphenol ethoxylate derivative and NPEs are restricted under EU REACH (Annex XVII) because of environmental and endocrine concerns; CIR reviewed nonoxynols and concluded use in rinse‑off cosmetics is acceptable (supports lower consumer hazard), so class‑based concern applies (h=1). Exposure from topical rinse‑off cosmetic use is low but measurable (e=1). Sources: REACH Annex XVII restriction on nonylphenol ethoxylates; CIR safety assessment of nonoxynols; PubChem entry linking CAS 31691‑97‑1 to nonylphenol ethoxylates.

Is ammonium nonoxynol-30 sulfate safe while breastfeeding?

Same rationale as pregnancy: class‑level concern from NP/NPEs (endocrine activity reported for nonylphenol in literature) gives h=1 and m=1 (theoretical/class‑based mechanism). No specific harmonised reproductive classification or human pregnancy/breastmilk transfer data for this exact ammonium salt were found; topical rinse‑off exposure to nursing parent is low (e=1). Sources: CIR nonoxynol assessment; PubChem; ECHA/REACH documentation on NPE restrictions.

Is ammonium nonoxynol-30 sulfate safe for baby skin?

Hazard and mechanism remain class‑based (h=1, m=1). Because infant (0–3 yr) skin has higher permeability and surface‑area‑to‑weight, exposure score is increased by +1 (adult e=1 → baby e=2). No infant‑specific dermal absorption or toxicity studies for ammonium nonoxynol‑30 sulfate were located. CIR concluded nonoxynols are safe in rinse‑off uses, which reduces practical concern for typical rinse‑off cosmetic use on children, but class restrictions (REACH Annex XVII) reflect broader regulatory caution. Sources: CIR review; REACH Annex XVII; PubChem.
