Description

This invention relates to a liquid detergent composition for textile products. In the field of liquid detergents for textile products, there is growing awareness of environmental impact. Therefore, efforts are being made to reduce energy consumption in logistics and decrease waste by miniaturizing the containers that hold these liquid detergents. With the miniaturization of containers, there is a growing demand for liquid detergents that not only have high cleaning power but also require less detergent per wash. To meet these demands, concentrated liquid detergents with a higher concentration of surfactants have been proposed (for example, Patent Document 1). Japanese Patent Publication No. 2010-229387 A liquid detergent composition for textile products according to one embodiment of the present invention (hereinafter also simply referred to as "liquid detergent composition") contains component (A), component (B), component (C), and water. <(A) Ingredients> Component (A) is a nonionic surfactant represented by the following formula (a1) (hereinafter also referred to as "nonionic surfactant (a1)"). (A) Component (A) may be used alone or in combination of two or more components. R 11 -O-[(EO) s / (A 11 O) t ]-(EO) u -R 12 ...(a1) [In formula (a1), R 11 is a linear hydrocarbon group having 8 to 22 carbon atoms, R 12 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or an alkenyl group having 2 to 6 carbon atoms, EO is an oxyethylene group, s is a number from 3 to 25 indicating the average repeating number of EO, A 11 O is at least one of an oxypropylene group and an oxybutylene group, t is a number from 0 to 6 indicating the average repeating number of A 11 O, and u is a number from 0 to 20 indicating the average repeating number of EO.] In formula (a1), the hydrocarbon group R 11 has 8 to 22 carbon atoms, preferably 10 to 18, and more preferably 12 to 18. The hydrocarbon group R 11 is linear. The hydrocarbon group R 11 may or may not have unsaturated bonds. The carbon atom of R 11 bonded to -O- can be either a primary or secondary carbon atom. If the carbon atom of R 11 bonded to -O- is a primary carbon atom, -O- bonds to the carbon atom at the end of the linear chain among the carbon atoms constituting R 11. If the carbon atom of R 11 bonded to -O- is a secondary carbon atom, -O- bonds to the carbon atom of R 11 that is not at the end of the linear chain. When R12 is an alkyl group, the number of carbon atoms is 1 to 6, and preferably 1 to 3. When R 12 is an alkenyl group, the number of carbon atoms is 2 to 6, and preferably 2 to 3. R12 is particularly preferably a hydrogen atom. s is 3 to 25, preferably 5 to 25, more preferably 7 to 20, even more preferably 7 to 18, and particularly preferably 7 to 15. t is between 0 and 6, preferably between 0 and 3, and more preferably 0. u is between 0 and 20, preferably between 0 and 15, and more preferably between 0 and 10. s+u is preferably 3 to 30, more preferably 5 to 25, even more preferably 5 to 20, particularly preferably 7 to 20, and most preferably 7 to 15. When t is not 0, that is, when the nonionic surfactant (a1) has EO and an oxypropylene group (hereinafter also referred to as "PO"), EO and an oxybutylene group (hereinafter also referred to as "BO"), or EO, PO and BO, there are no particular limitations on the distribution (order of arrangement ) of EO and PO, EO and BO, or EO, PO and BO in [(EO) s / ( A 11 O) t]. These may be arranged in blocks or randomly. Also, EO may be bonded to "R 11 - O -", or PO or BO may be bonded to "R 11 - O -". If t is not 0, the nonionic surfactant (a1) preferably has EO and PO, or EO and BO. <(B) component> Component (B) is a Garbet alcohol-type nonionic surfactant represented by the following formula (b1). (B) Component may be used alone or in combination of two or more types. R 1 -CHR 2 -CH 2 -O-(R 3 O) p -H ...
