Branded Ingredient

Suppliers sell materials, not products, and a material that can be told apart from its competitors acquires a name, a logo and a folder of studies. Brands buy it and print the name on the box. Sometimes what has been bought is a single molecule at a particular grade; often it is a blend — a little active carried in solvent, with the trademark on the whole blend.

The studies behind such a name are usually the supplier's own: run or commissioned by the company selling the material, on the material rather than on any product made with it, at a use level the supplier recommends, and often in a plain base rather than a finished formula. That does not make them wrong, and suppliers do serious work. They are simply not independent, and were not run on the thing in your hand. Where a figure comes from a supplier's dossier, it is worth saying so.

The percentage stays hidden. Naming a trademarked complex says it is present, not at what level, and because blends are supplied dilute, present can mean far less active than the supplier's own studies used. Some brands publish the figure. Most do not, and asking is reasonable.

The name is still useful, for a different reason than intended: a trademark makes a material traceable. You can find out what it is, what it is meant to do, and whether the same material turns up in something cheaper.
