This invention relates to a fabric care composition comprising a polycarboxylic acid or a derivative thereof, a catalyst and a thermoplastic elastomer, a method of treating fabric with such a composition and the use of such a composition to increase the tensile strength (especially the tear strength) of a fabric, to reduce creasing and/or wrinkling of a fabric and/or to improve the elasticity and/or shape retention of a fabric.
The laundry process generally has several benefits for fabric, the most common being to remove dirt and stains from the fabric during the wash cycle and to soften the fabric during the rinse cycle. However, there are numerous disadvantages associated with repeated use of conventional laundry treatment compositions and/or the actual laundry process; one of these being a fairly harsh treatment of fabric in the laundry process causing fabric to lose its shape.
One aspect of the present invention is therefore directed towards maintaining the new appearance of fabric, that is to give better return (after being stretched) to the articles original shape (shape retention).
