  • Patent number: 8309116
    Abstract: Personal care compositions comprising esters of 1,3-propanediol and acceptable carriers are provided. The esters can have at least 3% biobased carbon, and the compositions can further comprise 1,3-propanediol that is biologically-derived. Also provided are processes for producing personal care compositions comprising esters of 1,3-propanediol and acceptable carriers. The processes comprise providing biologically produced 1,3-propanediol, contacting the 1,3-propanediol with organic acids, which produces the esters, recovering the esters, and incorporating the esters into personal care formulations. Also provided are processes of making a personal care composition comprising providing an ester of 1,3 propanediol and mixing the ester with an acceptable carrier to form a personal care composition.

  • Publication number: 20120107260
    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.

  • Patent number: 8114423
    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) are derived predominantly from monomers (e.g., 1,3-propanediol) obtained from renewable resources, and are thus more environmentally friendly in terms of manufacture, use and disposal.

  • Patent number: 7960575
    Abstract: A process for forming an ester from 1,3-propanediol comprising providing 1,3-propanediol with at least 90% biobased carbon, contacting the 1,3-propanediol with an acid, thereby forming the ester, and recovering the ester is provided. The acid can be an organic acid. Additionally, a process for producing an ester, either or both a monoester and a diester, from biologically-produced 1,3-propanediol is provided. This process includes providing 1,3-propanediol produced biologically through fermentation and catalytic conversion of atmospheric carbon, contacting the 1,3-propanediol with an organic acid, wherein said ester is produced; and recovering the ester. In this process the 1,3-propanediol can have has at least 95% biobased carbon, or can have 100% biobased carbon.

  • Publication number: 20100233300
    Abstract: Compositions comprising 1,3-propanediol and an extraction product are provided, and the 1,3-propanediol in the composition is biologically derived. Also provided are processes for extracting an extract from a source. These processes comprise providing an ester of 1,3-propanediol and mixing the 1,3-propanediol ester with the source. This serves to extract the extract from the source into the ester. The processes also include separating the source from the ester and extract. Also provided are compositions comprising an ester of 1,3-propanediol and an extraction product. In these compositions, the ester can have at least 3% biobased carbon.

  • Publication number: 20090325853
    Abstract: A process for providing detergent compositions comprising synthesizing mono and di esters from biologically derived 1,3-propanediol an incorporating said esters into detergent formulations. The basic process involves producing and purifying biologically derived 1,3-propanediol, synthesizing mono and di esters by the condensation of 1,3-propanediol with an acid using a catalyst, recovering the ester and incorporating said ester into a detergent formulation. The compositions made from the biologically derived 1,3-propanediol are also encompassed by the invention.
