Where it comes from
A crosslinked copolymer of acrylic acid, methacrylic acid, methyl methacrylate and vinyl isodecanoate, all petrochemical monomers, partly neutralised with sodium hydroxide. Exact monomer ratios are not disclosed, so the sodium content is estimated.
In plain English
A thickening and stabilising polymer used in creams and lotions, built from several synthetic acrylate-family building blocks. Only the sodium neutraliser is natural in origin.
