Frequently asked questions

Is isobutane safe during pregnancy?
Isobutane (CAS 75-28-5) has no harmonised reproductive classification in ECHA Annex VI and no CIR or SCCS safety findings indicating reproductive hazard; available registrations and PubChem list it as a volatile hydrocarbon/propellant with no reproductive toxicity evidence. In typical cosmetic use as an aerosol propellant exposure is primarily inhalation of a rapidly evaporating gas rather than dermal/systemic absorption, so pregnancy exposure from topical cosmetic use is considered negligible.
Is isobutane safe while breastfeeding?
No data indicate reproductive or lactation-specific toxicity for isobutane and there is no harmonised CLP repro classification; systemic transfer into breastmilk after cosmetic use is unlikely given its high volatility and lack of lipophilic biopersistence. Regulatory dossiers (ECHA registrations, PubChem summaries) do not report lactation hazards for cosmetic uses.
Is isobutane safe for baby skin?
Dermal exposure of infants (0–3 yr) to isobutane from cosmetic products is expected to be negligible — isobutane is a volatile propellant with minimal skin retention and no data showing developmental or infant-specific toxicity. Given lack of absorption and no reproductive/developmental signals in regulatory sources, infant skin use does not indicate a hazard.
