Abstract: Compositions comprising sun-care actives and self adapting polymers are disclosed. Self adapting polymers align themselves with the hydrophilic group pointing to the surface during application thus delivering an aesthetically pleasing surface to the consumers with a pleasant after feel. These polymers then rearrange upon contact with water so that the hydrophobic groups now point to the surface which then increases the water resistance of the formulation.

Optionally, the method may also include adding a crosslinking agent, diluent or both to the soy flour/urea adhesive and/or adding an emulsified or dispersed polymer. Adhesives and dispersions prepared according to the methods of this invention offer increased stability and strength properties.
