The product is applied to the skin in a finely divided form to give a dry, non-sticky deposit for absorbing skin moisture such as perspiration. The polymer is capable of absorbing an amount of moisture at least equal to its own weight after depositing the product onto the skin.
    Type: Grant

  • Patent number: 4662892
    Abstract: A composition for use in the dyeing of keratinous fibres, particularly human hair, in order to produce a true dark black color, comprises an aqueous, substantially oxygen-free solution of the dye-precursors 2-methoxy-p-phenylenediamine and 2,4-diaminophenol, the composition having a pH value of from 6 to 12. The molar concentration of one dye precursor to the other is preferably from 1:10 to 10:1, and together they form from 0.25 to 15% by weight of the composition. Optionally, the composition can also contain a detergent and/or a thickening agent.
