Description

[Detailed description of the invention] Detergent composition containing polyhydroxy fatty acid amide surfactant and clay softening system Technical field The present invention provides a softening through-the-touch system containing a clay softening system. UGH THE WASH) COMPOSITION.

Background technique Clays, particularly smectite clays, are known fabric softeners and fabric softeners. ・The use in The Wash is technically disclosed. What represents this technology is the specification of British Patent B 1 400 898. In addition, the application of these clays It is equally well recognized that clothing is never perfect. In fact, a typical European Under state washing conditions, less than half of the available clay is deposited on the fabric and the remainder is washed away after subsequent rinsing. It is rinsed away with the washing liquid during the process.

One reason for incomplete adhesion is that when used in substantial amounts (i.e., greater than 4%) is due to the negative interaction between normal nonionic surfactants and clays. It was discovered that

Therefore, so far, in order to achieve good softening performance of clay, Limiting the amount of nonionic surfactant in the softening through-the-wash composition or clay flocculants, such as those disclosed in EP-A 299,575. It was necessary to add something.

Polyhydroxy fatty acid amide, which acts as a nonionic surfactant, improves fabric softness. It has now been found that it is better compatible with softened clays.

This finding is now better due to the large amounts of nonionic surfactants that can be given. Increased clay cleaning performance and without the absolute need for clay flocculants Treated with softening through-the-wash compositions that exhibit better softening performance for adhesion. make it possible to
