Title DISINFECTANT COMPOSITION, CLEANING COMPOSITION, ANTIFOULING COMPOSITION, VIRUS-INACTIVATING COMPOSITION AND NON-BACTERICIDAL COMPOSITION, AND COMPOSITION FOR REMOVING BIOFILM AND INHIBITING BIOFILM FORMATION
Abstract The purpose of the present invention is to provide a novel disinfectant composition, a novel cleaning composition, a novel antifouling composition and a novel virus-inactivating composition, a novel composition for removing a biofilm and inhibiting the formation of a biofilm, and a novel non-bactericidal composition. According to the present invention, a disinfectant composition, a cleaning composition, an antifouling composition and a virus-inactivating composition each comprising sophorolipid and sodium dodecyl sulfate (SDS) are provided. According to the present invention, a composition for removing a biofilm and/or inhibiting the formation of a biofilm, which comprises sophorolipid and SDS, is also provided. According to the present invention, a non-bactericidal composition containing sophorolipid is further provided.
Outline of related art and contending technology BACKGROUND ART
Cleaning compositions containing a surfactant as an active ingredient are widely known, but they are mainly chemically synthesized, and environmental toxicity thereof is a major problem. In contrast, biosurfactants have been problematic for practical use, although there are few problems of safety with respect to the human body and the environment, and are expensive.
Soiled materials also include bacteria-forming biofilms, which are widely found in the environment and present various problems in the life of people. For example, the formation of a biofilm on a catheter in the medical field causes chronic infections, and the formation of a biofilm on food processing equipment or cookware in the food field causes food poisoning. both of these are significant problems from the perspective of hygiene management. Furthermore, biofilms are often reformed once removed and are not easy to completely remove. Examples of cleaning compositions proposed so far for the purpose of removing and suppressing the formation of biofilms include those disclosed in Patent Documents 1 and 2.
Surfactants are also known to be effective in inactivating viruses, and are thought to be inactivated by destroying the viral envelope (film-like structure found in viral particles). Non-Patent Document 2 describes an example of a virus inactivating composition having a surfactant proposed so far as an active ingredient.
