Syensqo introduces Mirapol Hygiene Boost, a freshness-boosting polymer that interacts “optimally” with fabric surfaces to prevent the development and buildup of persistent odors after repeated washes — a phenomenon labeled as “permastink.” “Amid the growing trend of freshness claims in laundry products, consumers are increasingly seeking effective solutions against persistent malodors,” says Max Chabert, Home Care Global marketing manager at Syensqo.
