Description
Technical Field
The invention relates to a bactericidal detergent composition for hard surfaces.
Background
In facilities surrounding our living environment, there are various hard surfaces made of ceramic tiles, plastics, metals, etc., which are exposed to environments where various kinds of dirt adhere in a living scene. Among them, hard surfaces used in bathrooms, kitchens, floors, etc. are also surfaces that people regularly contact, and therefore, a large amount of dirt is easily left and accumulated, and further, they have a property that they are difficult to clean and remove.
In general, a composition suitable for various applications is used as a hard surface cleaner for removing various stains on a treatment target such as a bathroom, a kitchen, and a floor. For example, as a cleaning agent for kitchen surroundings used in kitchen surroundings such as a kitchen range, an oven, a wall or a mat around the kitchen range, and an exhaust fan, a cleaning agent containing a surfactant, a solvent, and an alkaline agent is used in order to remove oil stains that have been deteriorated by the action of heat, sunlight, oxygen in the air, and the like. In addition, as a bathroom cleaner used in bathrooms such as bathtubs, bathroom walls, and floors, a cleaner containing a surfactant, a solvent, a metal ion-blocking agent, and the like is used in order to remove dirt of metal soap, particularly fatty acid calcium salt.
In addition, when cleaning hard surfaces around toilets, bathrooms, kitchens, and the like, it is desired to obtain cleaning power and excellent bactericidal properties. Therefore, a bactericidal component is added to the hard surface cleaning agent.
