Detergent composition comprising detersive surfactant and biodegradable graft polymers

A detergent composition comprising a detersive surfactant and a graft polymer comprising:

• (A) a copolymer backbone as a graft base, wherein said copolymer backbone (A) is obtainable by polymerization of at least two monomers selected from the group of ethylene oxide, 1,2-propylene oxide, 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentene oxide or 2,3-pentene oxide,
• a. wherein the distribution of the alkylene oxide moieties within the copolymer backbone is in random order, and
• b. wherein the molecular weight of the copolymer backbone Mn in g/mol is within 500 to 7000,
• and
• (B) polymeric sidechains grafted onto the copolymer backbone, wherein said polymeric sidechains (B) are obtainable by polymerization of at least one vinyl ester monomer (B1), and optionally at least one other monomer (B2), wherein—if present—the weight ratio of monomer (B2) to monomer (B1) is less than 0.5, preferably less than 0.4, more preferably less than 0.3, even more preferably less than 0.2, and most preferably less than 0.1,
• comprising in percent by weight in relation to the total weight of the graft polymer
• 25 to 85%, preferably 30 to 80%, more preferably 35 to 80%, even more preferably 40 to 75%, and most preferably 55 to 75%, of the copolymer backbone (A),
• and
• 15 to 75%, preferably 20 to 70%, more preferably 20 to 65%, even more preferably 25 to 60%, most preferably 25 to 45%, of the polymeric sidechains (B).
