Abstract:
1. A method of washing a fabric product, comprising applying to an object to wash a liquid detergent composition comprising the following components (a), (b), (c) and (f), wherein the total sum of contents of component (a) and component (b) is from 50 to 90% by mass in terms of [(a) +(b)], and a mass ratio of component (a) to component (b) is from 25/75 to 90/10 in terms of (a)/(b); and wherein the pH value of the liquid detergent composition is 8 to 10 measured at 25° C. according to JIS K 3362:1998: Component (a): from 15 to 75% by mass of a nonionic surfactant obtained by a process comprising adding pl moles of ethylene oxide to a compound represented by R—OH, wherein R represents an alkyl group or an alkenyl group with from 8 to 18 carbon atoms, then adding q 1 moles of an alkylene oxide with from 3 to 5 carbon atoms and further adding p2moles of ethylene oxide, wherein p1 represents a number of from 3 to 30, q1 represents a number of from 1 to 5, (p1+p2) is from 14 to 50, and p1/(p1+p2) is from 0.2 to 0.8; Component (b): an anionic surfactant; Component (c): from 5 to 40% by mass of a water-miscible organic solvent; and Component (f): from 0.5 to 8% by mass of an alkaline agent.
