    Abstract: This application is directed to methods of assessing polymer deposition on dental surfaces using near infrared spectroscopy, providing a rapid and efficient method to screen for and identify optimal polymers for use in oral care formulations, (i) near infra red (IR) absorption of a dental substrate is measured in the absence of a polymer under test, and subsequently of the test sample comprising the dental substrate contacted with the test polymer. After washing or rinsing the test sample near IR of it is determined again (iii). The IR absorption of the test polymer itself is also measured (ii). Through the comparison of the three measurements (i), (ii), and (iii) the degree of deposition and retention of the test polymer on the test sample is determined.

    Abstract: Described herein are dual component oral care systems comprising a first component comprising a peroxygen compound and having a first pH and a second component comprising at least one salt of a weak mono or polyprotic acid and having a second pH wherein the second pH is higher than the first pH and is less than 10.0 wherein when combined the first and second components form a tooth-whitening composition having a pH of greater than 6.0 and less than 10.0 is provided.
