About
A prescription bronchodilator drug not permitted in cosmetic products due to its pharmacological activity and potential cardiovascular effects.
Metaproterenol sulfate is a synthetic catecholamine that acts primarily on beta-2 adrenergic receptors to relax bronchial smooth muscle. In the EU, substances with pharmacological activity are generally prohibited in cosmetic products under Regulation (EC) No 1223/2009. The H332 hazard statement (harmful if inhaled) and its status as a US-approved drug substance indicate significant safety concerns for dermal exposure.
Known concerns
- Pharmacologically active substance not permitted in EU cosmetics
- H332 acute inhalation toxicity
- Potential cardiovascular effects at systemic exposure
- Not evaluated for cosmetic use safety
