Abstract
1,234,422. Toothpastes. C. BLANC and J. ASSAL. 4 June, 1968 [5 June, 1967], No. 26642/68. Heading A5B. Toothpastes contain a substance which undergoes a chemical colour change after a sufficient tooth brushing operation has been carried out. The substance may be a pH indicator such as methyl red when the toothpaste is an acidic medium with an initial pH of 4.5, or the substance may be sensitive to the peroxidative action of haemoglobin such as. a mixture of benzidine, a peroxide and ethylenediaminetetraacetic acid. The toothpaste may contain a buffer to increase the time required to bring about the colour change e.g. citric acid and phosphates.
