That describes this inventory, not the law. No imported rule is not evidence that an ingredient is permitted: a rule may exist under another name or identifier, or in a dataset not yet imported here.
Chemical identity and properties
Pyridoxine
Pyridoxine is a hydroxymethylpyridine with hydroxymethyl groups at positions 4 and 5, a hydroxy group at position 3 and a methyl group at position 2. The 4-methanol form of vitamin B6, it is converted intoto pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters, sphingolipids and aminolevulinic acid. It has a role as a cofactor, a mouse metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a member of methylpyridines, a vitamin B6, a monohydroxypyridine and a hydroxymethylpyridine. — ChEBI

Vitamin B6
Vitamin B6 is a group of water-soluble vitamins essential for metabolism and normal physiological functions. B6 vitamins, including pyridoxine, pyridoxal, and pyridoxamine, are converted in vivo to pyridoxal phosphate, a cofactor necessary for the synthesis of amino acids, neurotransmitters, and sphingolipids. More than 100 enzymes involved in protein metabolism require vitamin B6 as a cofactor. Vitamin B6 is essential to red blood cell, nervous system, and immune systems functions and helps maintain normal blood glucose levels. Vitamin B6 is found in a wide variety of foods including cereals, beans, meat, poultry, fish, and some fruits and vegetables. (NCI04) — NCI Thesaurus (NCIt)
