On April 7th, 2005, domestic media reported that "Colgate toothpaste may contain carcinogenic ingredients". With the spread of this news in China, the brand trust of Colgate among consumers in China has been seriously questioned. Some supermarkets in major cities in China are looking forward to the final test results of relevant state departments, while some supermarkets have begun to take Colgate products off the shelves. Then some media said that not only Colgate toothpaste contains triclosan, Crest's all-purpose toothpaste and tea-refreshing toothpaste, but also black toothpaste, various therapeutic toothpastes and mouthwashes on the domestic market contain triclosan. Most of the domestic media reports originated from a report published in the British Evening Standard on April 15. However, the report only relayed a research process or possibility and did not reach a conclusion. As a result, many domestic media are busy interviewing experts, AQSIQ and Colgate toothpaste manufacturers. But at present, it seems that most media have not thought of consulting original research papers or interviewing the author himself. On April 18, the Legal and Government Affairs Department of Colgate-Palmolive Company in Guangzhou issued a statement to major media, saying that Colgate toothpaste was safe and there was misunderstanding in the media. On April 27th, 2005, Colgate-Palmolive Company reiterated the safety of Colgate Total Effect Toothpaste to consumers in China, but the press conference was not attended by authoritative organizations such as the Ministry of Health and AQSIQ. Next, Colgate released advertisements about toothpaste 100% safety on CCTV and other media to set the record straight.
