Ann M. Andrews has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Benzoate esters of polyalkoxylated block copolymers
    Patent number: 5271930
    Abstract: Benzoic acid esters of a polyalkoxylated block copolymer, i.e. PLURONICS, exhibit enhanced characteristics that make these esters ideally suited for skin and hair care compositions. These esters demonstrate enhanced capabilities as foam boosters, emollients, conditioners, clarifiers, solubilizers, and carriers (dilutents). In addition, both oxybenzone and benzocaine can be solubilized by these esters.
    Type: Grant
    Filed: November 20, 1991
    Date of Patent: December 21, 1993
    Assignee: Finetex, Inc.
    Inventors: Ismail I. Walele, Nicholas J. Scarangella, Anthony Ansaldi, Ann M. Andrews
  • Benzoate esters of alkoxylated methyl glucosides
    Patent number: 5270461
    Abstract: Benzoic acid esters of an ethoxylated methyl glucosides and of a propoxylated methyl glucosides exhibit enhanced characteristics that make these esters ideally suited for skin and hair care compositions. These esters demonstrate enhanced capabilities as foam boosters, emollients, conditioners, clarifiers, solubilizers, and carriers (diluents). In addition, oxybenzone, benzocaine, ibuprofin and dihydroxyacetone (DHA) can be solubilized by these esters. These esters have the ability to solubilize both hydrophilic and hydrophobic materials such as DHA. The benzoate esters have lower surface tensions than the glucam polyol molecules from which they were derived.
