Michael M. Carpenter 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).

  • Alkyl allyl amines and low voc hair styling compositions using same
    Patent number: 6361801
    Abstract: The present invention is directed to alkyl allyl amine monomers and their use as a polymerizate in a low VOC hair spray formulation. The hair spray formulation preferably includes a polymerizate of an alkyl allyl amine monomer, preferably an alkyl diallyl amine monomer alone or in combination with other known monomers. The hair spray formulation preferentially satisfies low VOC requirements while maintaining characteristics desired in a hair fixative product.

  • Method for using novel high solids polymer compositions as flocculation aids
    Patent number: 5725780
    Abstract: A method for flocculating suspended solids from an aqueous system containing water and said suspended solids comprising adding to said aqueous system an effective amount of a flocculating agent, wherein said flocculating agent is a pourable non-aqueous, polymer composition containing less than about 5%, water and greater than 60%, polymer solids. The polymer of the instant polymer compositions may be anionic, non-ionic, cationic or amphoteric. Related compositions are also claimed.
