Description;
White powder with a mild odor.
Polymethacrylic acid, also known as a-methacrylate or methakrylsaeure, belongs to the class of organic compounds known as carboxylic acids.
Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH.
Polymethacrylic acid has been detected, but not quantified in, asparagus (Asparagus officinalis) and roman camomiles (Chamaemelum nobile).
This could make Polymethacrylic acid a potential biomarker for the consumption of these foods.
