Abstract
An indoor cleaning tool having a dry fibrous base material is provided. An antigenicity-reducing composition including an antigenicity-reducing component, an oil and a surfactant are applied to the fibrous base material. Preferably, the antigenicity-reducing component is an extract of an olea or a ligustrum plant extracted with water or an organic solvent.
Claims28
A cleaning tool for indoor wiping comprising:
- an electrostatic fibrous base material electrostatically chargeable at least during use;
- wherein
- the electrostatic fibrous base material comprises a combination of two or more types of fiber having different triboelectric series and an antigenicity-reducing component for reducing antigenicity of allergy-inducing substances, and
- the antigenicity-reducing component includes oleuropein derived from an olive leaf extract and is achieved by
- adding ethanol to the extract to prepare a 0.6% oleuropein solution defining an antigenicity-reducing agent;
- adding at least water to the antigenicity-reducing agent to prepare an antigenicity-reducing component dilute solution;
- and
- applying the antigenicity-reducing component dilute solution to the fibrous base material to obtain the antigenicity-reducing component.
