For example, E300 is ascorbic acid, E330 is citric acid.
addition of L-ascorbic acid up to certain limits.
5,6-O-Isopropylidene-L-ascorbic acid is produced by the reaction of L-ascorbic acid with acetone in the presence of sulfuric acid.
It is therefore appropriate to approve L-ascorbic acid.
A composition of L-ascorbic acid derivatives is described comprising L-ascorbic acid and lysine or lysine moieties, wherein L-ascorbic acid is covalently bound to the lysine or lysine moieties.
Sodium L-ascorbate; L-Ascorbic acid monosodium salt
Vitamin C is known by several different names, including ascorbic acid, ascorbate, L-ascorbic acid and L-ascorbate.
The present invention relates to topical aerosol compositions comprising L-ascorbic acid.
A primary advantage of the disclosed process is that high concentrations of extracellular L-ascorbic acid are produced and at the pH of the disclosed process, significant degradation of extracellular L-ascorbic acid by oxidation does not occur.
Further, any excess NO radicals are also deleted by the L-ascorbic acid.
An aqueous solution or solid substance containing ferrous ion and L-ascorbic acid, with the content of L-ascorbic acid being 2.0 parts by weight or more per 100 parts by weight of ferrous ion.
Positive test for ascorbic acid/colour reaction
The composition need not contain ascorbic acid in order to obtain desirable stability.
A biochemical compound is described comprising ascorbic acid and at least one essential aminoacid, wherein the ascorbic acid is covalently bound to the aminoacid.
