PROBLEM TO BE SOLVED: To provide an allergen reducing antimicrobial composition capable of effectively inhibiting generation of bad smell such as room-dry smell or half-dry smell, and capable of inhibiting generation of allergy by allergens adhered to washed articles during drying.SOLUTION: There is provided an allergen reducing antimicrobial composition containing an allergen reducing agent and a cationic antimicrobial composition, and the allergen reducing agent has a property for inactivating allergen by modifying proteins. There is provided an allergen reducing antimicrobial composition, which exhibit both of an action effect of allergen reduction (suppression) or inactivation, and a sterilization, disinfection or antibacterial action to bacteria, especially bacteria causing room dry smell at same time because the action effect of reduction or inactivation of allergen is not inhibited by the cationic antimicrobial composition.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】部屋干し臭または生乾き臭などの悪臭の発生を効果的に防ぐことができ、かつ乾燥中に洗濯物に付着したアレルゲンによるアレルギーの発生を抑制することができるアレルゲン低減抗菌性組成物の提供。【解決手段】アレルゲン低減剤と、カチオン系抗菌剤とを含有するもので、タンパク質を変性することによってアレルゲンを不活性化する性質を有するアレルゲン低減剤を含有するアレルゲン低減抗菌性組成物。カチオン系抗菌剤によって、アレルゲンの低減ないし不活性化の作用効果が阻害されないので、アレルゲン低減（抑制）ないし不活性化の作用効果と、細菌、特に部屋干し臭の原因菌に対して除菌、殺菌もしくは抗菌作用の両方を、同時に発揮するアレルゲン低減抗菌性組成物。【選択図】なし
