Title:
AQUEOUS SOLUTION FOR USE IN CLEANING VIA IRRADIATION BY ULTRAVIOLET RAYS AND/OR NEAR-ULTRAVIOLET VISIBLE LIGHT AND/OR LIGHT IN 800-900 NM NEAR-INFRARED REGION, DENTIFRICE INCLUDING SAID SOLUTION, DENTAL TREATMENT DEVICE, TOOTHBRUSH, AND TOOTH CLEANING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/199974
Kind Code:
A1
Abstract:
[Problem] Sterilization of an affected part has conventionally been attempted by supplying hydrogen peroxide water to the affected part to be sterilized, and irradiating the affected part with ultraviolet rays to decompose the hydrogen peroxide and generate hydroxy radicals. However, since ultraviolet rays decompose not only hydrogen peroxide but a variety of substances as well, it is possible that carcinogens and other chemical substances harmful to the human body will be formed by, inter alia, decomposition of stabilizers included in the hydrogen peroxide water. [Solution] An aqueous solution for use in intraoral cleaning via irradiation by ultraviolet rays and/or near-ultraviolet visible light and/or light in the 800-900 nm near-infrared region is employed as the hydrogen peroxide water, the aqueous solution having a hydrogen peroxide concentration of 1 to 7 w/v% and a hydrogen oxide stabilizer concentration of 81 ppm (mg/L) or less.
