Document Type and Number:
WIPO Patent Application WO/2013/084717
Kind Code:
A1
Abstract:
Provided are a cleaning agent composition and an acrylic acid (salt)-maleic acid (salt) copolymer composition having excellent calcium scavenging capability and gel resistance. Furthermore, a manufacturing method that can obtain the acrylic acid (salt)-maleic acid (salt) copolymer composition having these excellent properties is provided. The acrylic acid (salt)-maleic acid (salt) copolymer composition is a copolymer composition that contains acrylic acid (salt)-maleic acid (salt) copolymer and a low molecular compound containing a sulfur atom, wherein the copolymer includes a specific structural unit, the weighted average molecular weight of the copolymer is 2000 or higher and 10,000 or lower, the low molecular compound containing a sulfur atom includes 3-sulfopropionic acid (salt), and the amount of the 3-sulfopropionic acid (salt) is 0.01 to 10 mass%, in relation to 100 mass% of the total solid content of the copolymer composition.
