Abstract (en)
[origin: WO2018065177A1] The invention relates to a solid laundry detergent composition containing an amphoteric polymer, said amphoteric polyemer being characterized in that least 30% of its monomeric units are betaine units represented by the following formula (I): H2C=C(R1)-C(0)0-(CH2)n-N+(R2)(R3)-(CH2)p-X (I) wherein: • R1 represents a hydrogen atom or a linear or branched Ci to C6 alkyl group; • R2 and R3, independently of each other, represent an alkyl, hydroxyalkyl or aminoalkyl group in which the alkyl group is a linear or branched C1 to C6 alkyl; • n is an integer in the range of 1 to 4; • p is an integer in the range of 2 to 8; • X represents COO". The inventors have discovered that laundry detergent compositions containing the aforementioned amphoteric polymer are capable of increasing the oil repellency of fabrics.
