  • Patent number: 8409596
    Abstract: This invention relates to deodorant compositions containing polytrimethylene ether glycol homo- and copolymers and/or polytrimethylene glycol ester(s) in a variety of physical forms. In at least one embodiment, the polytrimethylene ether glycol homo- and copolymers and/or polytrimethylene glycol ester(s) can be made from monomers (e.g., 1,3-propanediol) obtained from renewable resources, and can thus be more environmentally friendly than conventional deodorant compositions in terms of manufacture, use and disposal.
