  • 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.

  • Patent number: 5122603
    Abstract: A method for purifying two distinct insulin mediators to substantial homogeneity, and relative purity values above 80%, comprises adsorption on first anion exchange resin and subsequently on a chelex cation exchange resin column. The chelex resin ion exchange column substantially increases the activity of the recovered mediator. Following purification, the already treated fraction is subjected to three successive thin layer chromatography purification steps, the last giving, in the presence of ninhydrin stain, a characteristic salmon-color spot, which is indicative of the presence of the mediator. This process can also be used as a screening process, the absence of the salmon-colored spot being indicative of the diabetic state. Structure information on the insulin mediators obtained is given.

  • Patent number: 5079355
    Abstract: The invention pertains to a process for the synthesis of polyol fatty acid polyesters involving transesterification of a reaction mixture comprising a soap emulsifier in which during the reaction at a degree of conversion within the range of from 15 to 60% the soap level is substantially reduced. By this process the high-viscosity and separating-out problems attached to the soap emulsifier in the later stages of the reaction are avoided.

  • Patent number: 5077397
    Abstract: Sialic acid derivative with active ester groups expressed with the formula [I] ##STR1## Where R.sup.1 denotes hydrogen or an acetyl group, R.sup.2 denotes hydrogen or a lower alkyl group, R.sup.3 denotes C.sub.2 H.sub.4, C.sub.3 H.sub.6 or C.sub.2 H.sub.2, R.sup.4 denotes an hydroxyl group, the residue left after removing hydrogen from the alcohol portion of the active ester or alkyloxycarbonyloxy group, AC denotes an acetyl group, Ph denotes an phenyl group, and X denotes oxygen or sulfur. This sialic acid derivative has high reactivity because it has active ester groups in the molecules and can be used as a raw material or intermediate for synthesis of various sialic acid derivatives.

  • Patent number: 5071975
    Abstract: A process for preparing polyol fatty acid polyesters, e.g. sucrose polyesters (SPE) is improved by(1) mixing the polyol with an alkaline catalyst such as KOH, NaOH or their carbonates, preferably in aqueous solution or dissolved in C.sub.1-5 alcohols or ketones at atmospheric pressure and 10.degree.-80.degree. C.(2) preparing a mixture of fatty acid lower alkyl esters with an emulsifier, preferably a fatty acid soap, and(3) adding the alkaline polyol solution to the mixture of (2), whereby preferably the solvent is removed during the addition of (1) to (2), e.g. at 60.degree. C. and 5 mbar.The ratio fatty acid lower alkyl esters:polyol is preferably (10-20):1.The reaction is improved so that SPE are formed at 110.degree.-145.degree. C. within 5-10 hours.
