摘要:
A surfactant concentrate is provided that includes C8-C22 acyl amido compounds, a polyol and C8-C22 fatty acids. The concentrate is formed via an interesterification reaction between a C1-C3 alkyl ester of a C8-C22 fatty acid and an amino compound or salt thereof in a polyol. The resultant surfactant concentrate will have a Hunter Lab Color Scale value L ranging from 70 to 100.

摘要:
Oil-in-water emulsions can be formed using surfactants with biospecific headgroups. Emulsion droplets adhere to surfaces of microorganisms or to various biological surface bearing appropriate adhesins, thus delivering surfactant materials directly to various surfaces. Lipophilic materials and essential oils can be targeted in this way. The emulsions may be incorporated into oral hygiene non-food compositions or compositions for topical application to skin, hair or nails.
摘要:
A process of preparing N-substituted aldonamides, the process including the steps of mixing and reacting an aldonolactone and an amine in an organic polar solvent, in the presence of an antioxidant and a reducing agent. The aldonamides have improved color; the discoloration or browning of the aldonamides upon storage or elevated temperature processing is eliminated or substantially minimized.
摘要:
N-substituted aldonamides are synthesized by the reaction of alkylamines and aldonolactone. Commercially available sources of aldonolactones (e.g., lactobiono-1,5-lactone) include aldonic acid (e.g., lactobionic acid). The presence of the acid leads to the formation of an ammonium salt impurity. The ammonium salt formation during the synthesis of N-alkyl aldonamides was minimized by the addition of an external acid. External acids and, optionally, emulsifiers were utilized to substantially reduce or eliminate the formation of an ammonium salt and to obtain N-substituted aldonamides of high purity.
