• wherein R14 is of formula (VI);
• and wherein each R1 is independently selected from the group consisting of formula (II), formula (III), formula (IV) and formula (V)
• wherein the * indicates the point of attachment to formula (I);
• wherein each R2 is independently of formula (VI);
• wherein the * indicates the point of attachment to formula (I);
• wherein each R3 is independently according to formula (VI);
• and wherein each R4 is independently selected from the group consisting of a hydrogen and a methyl group;
• wherein the * indicates the point of attachment to formula (I);
• wherein each R5 is independently according to formula (VI);
• wherein f is 1 to 2;

• wherein the * indicates the point of attachment to formula (I);
• and wherein each R6 is independently according to formula (VI);
• wherein the * indicates the point of attachment to the associated base formula;
• wherein R7 is selected from the group consisting of a hydrogen and a C1-22 alkyl group;
• wherein each R8 and R9 is independently selected from the group consisting of a hydrogen and a C1-2 alkyl group, with the proviso that at least one of R8 and R9 is a hydrogen in each subunit a;
• and wherein a is 0 to 30, with the proviso that a is 2 to 30 in 70 to 100 mol % of the occurrences of formula (VI) in the cleaning booster.
