Regular soap and water are just as effective as triclosan-based products for hygiene — without the long-term risks.
🧠 Enrichment Notes (UPSC Lens)
- Regulatory status:
- Partially banned by US FDA
- Restricted in several countries
- India: limited regulation so far
- Common UPSC Trap:
- Assuming all antimicrobials are preservatives (❌)
- Exam Value:
- Connects chemistry, health, regulation, and environment
🪶 IAS Monk Closing Whisper
More chemicals do not always mean more protection.
