A method for preparing fatty hydroxamic acids and salts thereof comprising reacting a fatty acid derivative with an aqueous solution of hydroxylamine.

The invention concerns the preparation of cationic surfactants derived from the condensation of an acid, preferably a fatty acid or a hydroxy acid with a number of carbon atoms of 8 14 with esterified amino acids, preferably basic-type amino acids, more preferably (L)-arginine. The method comprises a first step in which the esterifiction of the amino acid with an alcohol is performed and a second step for the condensation with a chloride of an acid, preferably an acyl chloride of a fatty acid or...

Described is a genus of undecatrienoic acid derivatives useful in imparting, augmenting and/or enhancing flavors, aromas and somatosensory effects in or to consumable materials such as foods, beverages, skin care products, oral care products, medicinal products and the like. Also described is a synthesis process for producing such derivatives.

Fluorinated compounds and emulsions including the compounds. The compositions are useful as oxygen carriers and surfactants. In one embodiment, the fluorinated compound is pH sensitive. In one embodiment, the fluorinated compound is a vitamin E derivative. In one embodiment, the fluorinated compound is a vitamin K derivative.

A photoaffinity-labeled sphingomyelin analog of the following formula: ##STR00001## wherein R.sup.1 is C.sub.1-20 alkylene group, R.sup.5 is C.sub.1-20 alkyl group, aryl group or C.sub.1-6 alkyl group substituted by aryl group, Z is photoaffinity-labeled group and Me is methyl group, or an optically active compound thereof.

Amides are prepared by reacting an aromatic amine with an acid chloride in the presence of a neutralizing agent and a catalytic amount of a strongly basic tertiary amine; for example, N-(4-anilinophenyl) methacrylamide prepared by reacting p-aminodiphenylamine with methacryloyl chloride in the presence of sodium carbonate and triethylamine.

Novel analogs of arachidonylethanolamide are presented which have higher affinities for the cannabinoid CB1 and/or CB2 receptor sites. Further, most of the analogs exhibit greater metabolic stability than arachidonylethanolamide. The improved receptor affinity and selectivity and/or greater metabolic stability make these analogs therapeutically useful as medications for relief of pain caused by cancer and nausea caused by chemotherapy, as well as for peripheral pain. The compounds may also be us...

Novel alkanolamides prepared by the reaction of an alkanolamine and shea butter, preferably mild-processed shea butter (MPSB). Materials of the present invention are useful as cosmetic and personal care ingredients; they thicken shampoos and body washes, stabilize foam, and deliver to the hair and skin highly desirable unsaponifiables present in shea butter, including natural antioxidants.

Novel dimethyl amidopropyl amines prepared by the reaction of dimethyl amidopropyl amine (DMAPA) and shea butter, preferably mild-processed shea butter (MPSB). Materials of the present invention are useful as cosmetic and personal care ingredients, allowing for the delivery of highly desirable active ingredients present in shea butter including natural antioxidants, in a cationic material that is substantive to the skin and hair.

Processes for preparing amides of retinoic acid are disclosed. Intermediates useful in the preparation of amides of retinoic acid are also disclosed. In one version of the invention, fenretinide is produced via activation of retinoic acid (tretinoin) via its corresponding mixed anhydride or mixed carbonate followed by reaction of the activated intermediate with 4-aminophenol. Other amides of retinoic acid and isomers of retinoic acid, such as the 9-cis-form or 13-cis-form can also be made by thi...
