标题:An Improved Greener Esterification Of Fatty Alcohols Using A Renewable Acid-ionic Liquid Couple As Catalyst-solvent
摘要:We Have Developed A Simple And Efficient Method For The Esterification Of Various Organic Acids With C4-C18 Alcohols Using The 1-octyl-3-Methyl-Imidazolium Tetrafluoroborate-Para-Toluenesulphonic Acid (Omim/bf4-Ptsa) Couple,Without Organic Solvent,Either By Classic Heating Or By Microwave Irradiation. The Utilisation Of The Omim/bf4-Ptsa Couple Presents Considerable Advantages: High Yield,Low Temperature,Short Reaction Time,Isolation Of The Ester By Simple Decantation,Easy Reuse Of The Catalyst Couple.

标题 :Compositions comprising a manganese mineral and methods of use
发明人:REYNOLDS RUTH
权利人:OHM CREATIONS LLC
摘要:Compositions comprising a manganese mineral are provided. In specific embodiments, the manganese mineral contains manganese carbonate (MnCO 3 ), which may be in the form of rhodochrosite. The compositions may be administered topically to a subject, or in some versions by inhalation. For example, the compositions may be administered by direct contact with the subject's skin or by inhalation through the subject's nasal passages or mouth. Such application of the disclosed compositions may increase the subject's collagen synthesis, prolidase activity (an enzyme responsible for collagen function), and manganese superoxide dismutase activity (an antioxidant having manganese in its active site) in the subject.

摘要:This invention provides compositions and methods of manufacturing such compositions that employ GRAS compounds which can act to promote the generation of stem, epidermal or other skin cells in the epidermis, activation of collagen synthesis, activation of hyaluronic acid synthesis, enhanced skin hydration, and dermal healing by stimulating stem cell and fibroblast migration to sites of needed repair. These compositions and methods are useful for rejuvenating the skin and for treating some skin-related aging or other dermal damaging conditions, including wrinkle reduction and treatment of minor dermal wounds.
