  • Astringent or degreasing lotion
    Patent number: 4294823
    Abstract: A skin care product such as a cleansing lotion or pre- or aftershave lotion comprising ethanol, water, spherical polymer or copolymer microspheres, e.g. of polyethylene, polystyrene or polymethylmethacrylate, and a suspending agent for the microspheres. The ethanol:water weight ratio is in the range 1:19 to 19:1 and the microspheres, which may be sized from 5 to 7 microns, amount to 3 to 10% by weight of the product. The microspheres have a smoothing and matting effect on the skin, improving the observed degreasing effect of the product.

  • Cosmetic degreasing and matting composition
    Patent number: 4246257
    Abstract: Skin treatment product for greasy or oily skin comprising an unpigmented oil-in-water or water-in-oil emulsion having dispersed therein 3 to 10% by weight of spherical polymer or copolymer particles having an average size of 5 to 15 microns. The polymer or copolymer particles are cross-linked polystyrene, polymethylmethacrylate or polyethylene microspheres. The oil of the emulsion is a volatile organic liquid in the amount of 1 to 30% of the weight of the emulsion and may be a silicone or silicon glycol.
