Abstract
A cleaning composition for an oral appliance, including (A) and (B). (A) 0.05 mass % or more and 8 mass % or less of an anionic homopolymer or copolymer which has a mass average molecular weight of 2,000 or higher and 500,000 or lower and includes a constituent unit derived from (a1) an anionic monomer having a carboxyl group, a sulfo group, or a phosphoric acid group. (B) one or more surfactants selected from the group consisting of an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant.

A cleaning composition for an oral appliance, comprising the following components (A) and (B):
- (A) 0.05 mass % or more and 8 mass % or less of an anionic copolymer which has a mass average molecular weight of 2,000 or higher and 500,000 or lower and comprises a constituent unit derived from (a1) one or more anionic monomers selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, and sulfonic acid;
- and
- (B) 0.1 mass % or more and 15 mass % or less of one or more surfactants selected from the group consisting of an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, wherein
- a mass ratio of a content of the component (A) to a content of the component (B), ((A)/(B)), is 0.05 or more and 50 or less, and
- a content of (C), which is a monohydric or dihydric alcohol having 2 or more and 6 or less carbon atoms, is less than 8 mass %.
A method for cleaning an oral appliance, comprising applying a cleaning composition to the oral appliance, and leaving said cleaning composition in contact with said oral appliance for 3 to 30 minutes, followed by rinsing with water, the cleaning composition comprising the following components (A) and (B):
- (A) 0.05 mass % or more and 8 mass % or less of an anionic copolymer which has a mass average molecular weight of 2,000 or higher and 500,000 or lower and comprises a constituent unit derived from (a1) one or more anionic monomers selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, and sulfonic acid;
- and
- (B) 0.1 mass % or more and 15 mass % or less of one or more surfactants selected from the group consisting of an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, wherein
- a mass ratio of a content of the component (A) to a content of the component (B), ((A)/(B)), is 0.05 or more and 50 or less, and
- a content of (C), which is a monohydric or dihydric alcohol having 2 or more and 6 or less carbon atoms, is less than 8 mass %.
