D-malic acid is supplied at ≥98.0% assay on the dried basis, with ≥99.0% enantiomeric purity on a separate line. The two numbers answer different questions, and only one of them can catch a stereoche

Soy protein is a family name; the two grades that carry most of the trade differ by about twenty points of protein.
That difference decides the fill weight, the cost per gram of protein and the cla

The 0.6% cosmetic limit is measured as acid, not as powder. What that does to a sodium dehydroacetate dose, and how to pair it without breaking two limits.

Tea polyphenols grades differ by EGCG share, caffeine per serving and which daily limit applies. Read the ladder and the certificate before you order.

Oligopeptide-1 is the same three-amino-acid sequence sold under at least four names, and one of those names carries copper while the others do not. That single difference changes colour, storage tempe

Four cosmetic peptides on one catalogue state their recommended use level in two units, over a span of four orders of magnitude. That is not a mistake in the sheets; it is what happens when use level

Bisphenol S across three grades: what the assay figure does and does not tell you, the six documents a shipment needs, and where the EU food contact restriction attaches.
