Abstract
The present invention provides a detergent composition for textile products, containing the following component (A) and component (B): component (A): an internal olefin sulfonate having 16 or more and 18 or less carbons; and component (B): an alkyl sulfate having 12 or more and 14 or less carbons.
Claims11
A detergent composition for textile products, comprising the following component (A), component (B) and water:
- component (A):
- an internal olefin sulfonate having 16 or more and 18 or less carbons;
- and
- component (B):
- one or more anionic surfactants selected from an alkyl sulfate having 12 or more and 14 or less carbons and an alkane sulfonate having 12 or more and 14 or less carbons,
- wherein the component (A) is an internal olefin sulfonate having 16 or more and 18 or less carbons and, in the internal olefin sulfonate, a mass ratio of an internal olefin sulfonate having the sulfonate group at position 2 or higher and 4 or lower and having 16 or more and 18 or less carbons (IO-1S) to an internal olefin sulfonate having the sulfonate group at position 5 or higher and having 16 or more and 18 or less carbons (IO-2S), (IO-1S)/(IO-2S), is 0.75 or more and 5.5 or less;
- wherein a mass ratio of the content of the component (B) to the content of the component (A), (B)/(A), is 0.25 or more and 6 or less, and
- wherein the composition is used by diluting with water having a hardness of 4° dH or more in terms of German hardness and the total content of component A and the total content of component B is 1 mass % or more and 50 mass % or less.

A method for improving the resistance to hardness of a detergent composition for textile products, comprising using the following component (A) and the component (B) in combination:
- component (A):
- an internal olefin sulfonate having 16 or more and 18 or less carbons;
- and
- component (B):
- one or more anionic surfactants selected from an alkyl sulfate having 12 or more and 14 or less carbons and an alkane sulfonate having 12 or more and 14 or less carbons,
