Abstract
The behaviour of various soil and colour pigments which contribute to redepositions in detergency was studied. Though the systems of surfactants and builders are essential to a good soil suspending power of the liquor they do not provide totally satisfying washing results when used as such. Today polymers are therefore used to inhibit graying and colour transfer. They are optimized in their special effects. Their efficiency correlates with the physico-chemical parameters of the interactions of additives and pigments or additives and fibres, respectively. The connection between the molecular structure, the properties and the specific effects of polymer additives is demonstrated by examples. To optimize a formulation one must not only consider the effect of a single additive, as there are often additional effects and additives can complement or affect adversely each other. The difficulties of a complex system of pigment substrates, additives and fibres are demonstrated by the examples of optimized combinations of vinylpyrrolidone polymers and amphiphilic block polymers.
