Editing Chlorophyll (section)

===In marketing===
In years 1950–1953 in particular, chlorophyll was used as a marketing tool to promote toothpaste, sanitary towels, soap and other products. This was based on claims that it was an odor blocker — a finding from research by F. Howard Westcott in the 1940s — and the commercial value of this attribute in advertising led to many companies creating brands containing the compound. However, it was soon determined that the hype surrounding chlorophyll was not warranted and the underlying research may even have been a hoax. As a result, brands rapidly discontinued its use. In the 2020s, chlorophyll again became the subject of unsubstantiated medical claims, as [[Social media marketing|social media influencers]] promoted its use in the form of "chlorophyll water", for example.<ref name=O'Hagan>{{cite journal |doi=10.1108/jhrm-11-2021-0057 |doi-access=free |title=All that glistens is not (Green) gold: Historicising the contemporary chlorophyll fad through a multimodal analysis of Swedish marketing, 1950–1953 |date=2022 | vauthors = O'Hagan LA |journal=Journal of Historical Research in Marketing |volume=14 |issue=3 |pages=374–398 }}</ref>
