Home care compositions

A fabric care composition comprising:

• (a) an esterquat, and
• (b) a carbodiimide,
• wherein the carbodiimide is a compound of formula:
• R—N═C═N—R′
• wherein:
• R and R′ are each independently C1-6 alkyl, aryl, cycloalkyl, or —(CH2)xNRmRn;
• wherein x is a number from 1 to 5;
• and
• Rm and Rn are each independently H or C1-6 alkyl;
• wherein the carbodiimide is a dimer of a compound of formula R—N═C═N—R′, wherein R and R′ are each independently is a C1-6 alkyl, aryl, cycloalkyl, or —(CH2)xNRmRn;
• wherein x is an integer from 1 to 3, Rm and Rn are each independently C1-6 alkyl;
• or
• wherein the carbodiimide is a polymer of a compound of formula R—N═C═N—R′, wherein R and R′ are each independently is a C1-6 alkyl, aryl, cycloalkyl, or —(CH2)xNRmRn;
• wherein x is an integer from 1 to 3, Rm and Rn are each independently C1-6 alkyl.
