Liquid detergent composition

2:

• The liquid detergent composition according to claim 1, wherein (b2)/(b1)+(b2), which is a mass ratio of a content of the component (b2) to a total content of the component (b1) and the component (b2), in the liquid detergent composition, is 0.1 or more and 0.83 or less.

3:

• The liquid detergent composition according to claim 1, wherein [(b1)+(b2)]/(a), which is a mass ratio of a total content of the component (b1) and the component (b2) to a content of the component (a) in the liquid detergent composition, is 0.13 or more and 0.65 or less.

5:

• The liquid detergent composition according to claim 1, wherein the component (b1) is one or more selected from the group consisting of an alkanolamine and an amino acid.

6:

• The liquid detergent composition according to claim 1, wherein the component (b1) is one or more selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine, and glycine.

7:

• The liquid detergent composition according to claim 1, wherein the component (b2) is one or more selected from the group consisting of sodium carbonate, potassium carbonate, sodium sesquicarbonate, potassium sesquicarbonate, sodium hydrogen carbonate, and potassium hydrogen carbonate.

8:

• The liquid detergent composition according to claim 1, wherein the composition is for use in washing textile products.

9:

11:

• The method according to claim 10, wherein (b2)/[(b1)+(b2)], which is a mass ratio of a content of the component (b2) to a total content of the component (b1) and the component (b2) in the washing liquid, is 0.1 or more and 0.83 or less.

12:

• The method according to claim 10, wherein (b1)+(b2)/(a), which is a mass ratio of a total content of the component (b1) and the component (b2) to a content of the component (a), in the washing liquid, is 0.13 or more and 0.65 or less.
