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.

A tooth whitening oral care composition is made by combining ingredients comprising flakes of a water soluble whitening film, a dye with a hue angle in the CIELAB system ranging from 200 to 320 degrees, and an orally acceptable carrier vehicle. The flakes of the water soluble whitening film comprise: (a) a film-forming polymer comprising hydroxyalkyl cellulose wherein the hydroxyalkyl cellulose has a viscosity of about 1 to about 1000 millipascal seconds (mPa.Math.s) as determined as a 2% by in the CIELAB system ranging from 200 to 320 degrees.

The present invention relates to cosmetic agents having a low emulsifier content which include a combination of a specific non-ionic polyurethane polymer and at least two emulsifiers having different HLB values.
