  • Skin composition
    Patent number: 4822596
    Abstract: A personal antiperspirant product contains a moisture-absorbent polymer instead of or in addition to the usual metal salt. 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.

  • Antiperspirant emulsion
    Patent number: 4264586
    Abstract: An antiperspirant liquid composition in the form of an emulsion comprises a volatile polydimethylsiloxane, a wax, an antiperspirant agent, an emulsifier and water. The wax is first dissolved in the polydimethylsiloxane and then emulsified with the remaining ingredients. The composition can be sprayed on the skin yet is thick enough not to form runs or dribbles on the skin under the influence of gravity.
