What does the slash in polymer nomenclature, e.g. Acrylates/ Beheneth-25 Methacrylate Copolymer, mean? I was given a task to find SDS-Sheets for polymers/microplastic particles in cosmetics and I am confused, since there are often two chemicals divided by "/", e.g. Acrylates/ Beheneth-25 Methacrylate Copolymer. So would it be correct to look for the SDS-sheets for the both of them separately? Is it just the mixture of the two? Maybe someone can provide me with some information of how I am supposed to read these kinds of names.
Acrylates/Beheneth-25 Methacrylate Copolymer is an INCI name for a copolymer


  … formed from the ester of 2-methylpropenoic acid and docosanol, ethoxylated, 25 mol EO (average molar ratio) and one or more monomers of acrylic acid, methacrylic acid or one of their simple esters

Also known by the trademark Aculyn™ 28.
Dow Chemical provides cumulative MSDS datasheet (pdf) for the entire Aculyn family, so I assume you can use it for your copolymer as well.
