For thermosets, thermoplastic, rubbers and biopolymers, the first constituent is the major constituent, by example Galactomannan A. pavonina (0.5%w/v)/Glycerol (1.0%v/v)

The scientific name is the preferred label and the commercial one a synonym

The scientific name is composed of the names of the constituents separated by le character "/"

One material could belong to several categories. For composites and multilayers, the material must be referenced in one of those categories AND in the category of its main component. For instance metalized PLA belongs to "multilayers" and "Biopolymers" (because PLA is the main component).

Name of materials for Multilayers separate each layer by a "/", for Blend separate each component by a "_", for Composites begin by the % of fillers , name of filler / name of the matrix, for LbL indication of composition of the multilayers between brackets followed by the number of mutlilayers, example (Polyacrylamide/Sodium Montmorillonite)5- Polyethylene terephthalate
