  • Patent number: 4263363
    Abstract: A water-in-oil emulsion at a ratio of 80/20 or less when incorporated into a water absorbing material (such as a polyurethane sponge) will aid in retaining water that may be subsequently added to the absorbing material. The effect is believed due to the increased viscosity of the emulsion when water is added. The effect is particularly useful for improving urine retention of diapers, such as disposable diapers or similar articles.
