Kororo mouthwash

Kororo mouthwash is an antiseptic gargle solution developed by Saraya Co., Ltd., primarily used for oral hygiene and the prevention of throat infections. Its active ingredient is typically lauryldiaminoethylglycine sodium, an amphoteric surfactant that provides bactericidal and cleaning actions. It is designed to disinfect the mouth and throat while removing odors and providing a refreshing sensation through the inclusion of l-menthol. In Japan, it is classified as a quasi-drug and is commonly found in public dispensing stations, offices, and healthcare facilities. The formulation is intended to be mild, making it suitable for frequent use without the harshness associated with some other antiseptic gargles.
