| abstract |
The invention is a bactericide composition comprising from 0.1 mass% to 5 mass% of component (A), component (B), and optionally component (C), wherein the mass ratio, component (C)/component (A), is from 0 to 1.2, and the mass ratio, (component (B) + component (C))/component (A), is from 0.1 to 6. Component (A): a specific quaternary ammonium salt including a C 12-16 aliphatic hydrocarbon group. Component (B): a specific sulfuric acid ester salt including a C 8-16 aliphatic hydrocarbon group. Component (C): at least one type of anion surfactant selected from component (c1) and component (c2). Component (c1): an alkyl sulfate salt including a C 8-20 linear aliphatic alkyl group. Component (c2): a C 8-20 fatty acid or salt thereof. |
