  • Patent number: 5053221
    Abstract: A novel mascara composition is disclosed. The composition comprises: (a) an effective amount of water; (b) an effective amount of microsphere particles selected from the group consisting of silica beads, polymethylmethacrylate beads, and combinations thereof; and (c) an effective amount of a water dispersible, high molecular weight, amorphous anionic polyester polymer having an approximate molecular weight, MN, of about 14,000 to about 16,000 and a melt viscosity at 200.degree. C. of about 2000 to about 42,000 poise as measured with a Sieglaff-McKelvey Capillary Rheometer, 100 sec.sup.-1 shear rate. The polyester polymer is added to the mascara composition as a water dispersion having a solids content of not more than about 40% by weight of the dispersion. Prepared mascara compositions contain silica beads polymethylmethacrylate beads and an effective amount of the emulsifier C12-C15 alcohols benzoate.
