  • Patent number: 9598358
    Abstract: Acylalkylisethionate esters are produced by reacting one or more carboxylic acids with one or more alkyl-substituted hydroxyalkyl sulfonates under esterification reaction conditions. The alkyl-substituted hydroxyalkyl sulfonates used as a raw material in producing the esters are prepared by reacting bisulfate with one or more alkylene oxides. The acylalkylisethionate esters may be used in consumer products.

  • Patent number: 7880346
    Abstract: Apparati and methods for generating electricity which comprise in one embodiment a pair of stationary magnets oriented so that their like poles are facing one another with a space between them, and having a stationary length of wire disposed in the space between said magnets of said pair and enabling or causing the passing of a piece of metal through said space sufficient to cause an electrical potential in the wire. In one embodiment, the length of wire comprises a coil of wire having any number of turns between about 10 and about 5000. In another embodiment, the length of wire comprises a plurality of serpentine sections or loops disposed along the length of a tube or other form inside of which the piece of metal is made to move.

  • Patent number: 7629487
    Abstract: Provided herein are catalysts useful in enabling and promoting the insertion of alkylene oxides into ester linkages. The esters employed as a substrate to be alkoxylated include esters of fatty acids, such as methyl esters of C14 to C22 fatty acids, and mono-, di-, and tri-esters of glycerine, including vegetable oils, animal fats, and plant oils. A catalyst according to the invention includes at least two alkaline earth compounds, which may include any known stable compounds of the alkaline earths, and optionally contains one or more additional materials such as a carboxylic acid or a polyalkylene glycol having a molecular weight between about 100 and 1500 or a C1-C10 alkyl-capped polyalkylene glycol having molecular weight between about 100 and 1500, which has been acidified with a strong mineral acid. The preferred alkaline earths employed are salts and compounds of magnesium and calcium.

  • Publication number: 20090215626
    Abstract: By the present invention, a surfactant system containing glyphosate has been created which can be used to yield formulations containing an ultra-high load of glyphosate, in which the glyphosate concentration is higher than previously possible in any agriculturally-acceptable formulation. Higher loadings are desirable to reduce shipping and container costs, as well as reduce wastes. The higher loading reduces storage requirements and allows the farmer to handle less volume of pesticide. The main advantage is that maximizing the loading minimizes the cost to deliver the active ingredient, which in turn maximizes economy in use of glyphosate.

  • Publication number: 20090110657
    Abstract: Provided are compositions which are suitable for topical application to mammalian skin for cleansing and anti-microbial properties. In one embodiment, the compositions include an ester of polyalkylene glycol monoazelate monolaurate. It is postulated that bacteria on or in the skin may cleave the ester linkage of a compound according to the present disclosure that is applied to the skin, which causes liberation of the acid moiety from the ester, which acid moiety then inhibits or kills the bacterium. Compositions according to the present disclosure may comprise skin creams, soaps, shampoos and lotions, and are especially effective in treating acne and acne-like skin ebullitions.

  • Publication number: 20090111875
    Abstract: Provided are compositions which are suitable for topical application to mammalian skin for cleansing and anti-microbial properties. In one embodiment, the compositions include a glyceryl monoazelate monolaurate ester. It is postulated that bacteria on or in the skin may cleave the ester linkage of a compound according to the present disclosure that is applied to the skin, which causes liberation of the acid moiety from the ester, which acid moiety then inhibits or kills the bacterium. Compositions according to the present disclosure may comprise skin creams, soaps, shampoos and lotions, and are especially effective in treating acne and acne-like skin ebullitions. The glyceryl portion of the molecules is believed to facilitate penetration of the ester into the skin prior to release of the azelate or laurate residue.

  • Publication number: 20040205599
    Abstract: The present invention provides patentability search reports and methods for producing same. The search reports of the present invention include a listing of prior art turned up during the course of a patentability search for a proposed invention, in addition to statements pointing out the differences between the features of the proposed invention and those contained in the prior art. However, a report according to the present invention also includes a draft patent claim, which is preferably drafted by a patent Practitioner. By constructing a draft claim, it is possible for the writer of the report to put themselves in the place of a Patent Examiner and make a mock rejection(s) of the draft patent claim based upon the prior art identified during the course of the search. A report according to the invention may include a discussion of the merits of such mock rejections, and rebuttal arguments presented, including suggested means for obviating such mock rejections.
