The Health business of Lubrizol Life Science (LLS Health) manufactures high performance Carbopol® polymers and Noveon® polycarbophil, which have been used extensively in oral care applications for decades. Initially used in aqueous toothpaste formulations as a thickener and co-binder, Carbopol polymers are now preferred thickeners for anhydrous toothpaste formulations. They are also used in a variety of other toothpaste, mouth rinse, and denture adhesive products. LLS Health additionally manufactures tetraacetylethylenediamine (TAED) as a bleach activator for denture cleaners to prevent bacterial build-up.

Carbopol polymers and Noveon polycarbophil ingredients are utilized in oral care products as:
There are multiple grades of Carbopol polymers, each for specific applications and with slight chemical differences to provide various benefits. Products within the Carbopol polymer family are chemically similar in that they are all high molecular weight, crosslinked polyacrylic acid polymers. Noveon® AA-1 Polycarbophil USP is also a high molecular weight acrylic acid polymer but has a different crosslinking agent than Carbopol polymers. See Table 1 for our available polymer grades and their applicable dosage forms.
Our Carbopol and Noveon multifunctional polymers are:
