Abstract
A crosslinked, nonionic, amphiphilic polymer is prepared by polymerizing a monomer mixture comprising an amphiphilic additive. The obtained polymer is useful for forming a clearer yield stress fluid in combination with a surfactant. The yield stress fluid is capable of suspending insoluble materials in the presence of electrolytes, perfumes, fragrances and/or organic acid preservatives.
