15 Mar 2024 --- Colgate says its first all-purple toothpaste will instantly color-correct yellow tones “in one brush.” Colgate Optic White Purple uses Purple Brighteners and the company’s exclusive Micropolishing Technology to remove surface stains and tackle an “often long and expensive process” that can take days, weeks or months. “While brushing your teeth may seem to be one of the most basic steps to having a good oral routine, sometimes people forget that the outward appearance of their teeth also matters,” says Laura Vogel, senior director, Oral Care, Marketing Asia-Pacific, Colgate-Palmolive.
