摘要:The disclosure relates to methods of forming a dihydrochalcone using electrocatalytic dehydrogenation. In particular, the disclosure relates to methods of forming a dihydrochalcone electrocatalytically hydrogenating (ECH) a reactant compound over a catalytic cathode in a reaction medium having a non-alkaline pH value, thereby forming a dihydrochalcone product; wherein the reactant compound has a structure according to Formula (I). The method can be used to prepare dihydrochalcone sweeteners, such as, for example, naringin dihydrochalcone and neohesperidin dihydrochalcone.

摘要:A method for managing skin tone comprising reducing the synthesis of melanin by applying a skin treatment composition to skin. The skin treatment composition may include about 0.1 to about 25 wt. % of acetyl trifluoromethylphenyl valylglycine; about 0.5 to about 30 wt. % of a polyol; about 0.1 to about 30 wt. % of a silicone, fatty compound, or a mixtures thereof, wherein the skin treatment composition is an emulsion, and all weight percentages are based on the total weight of the skin treatment composition.
