Colgate goes into space

Colgate-Palmolive has announced plans to send the first-ever private sector oral care experiment to the International Space Station (ISS), under the sponsorship of the ISS U.S. National Laboratory. Colgate designed the experiment to learn more – in a unique microgravity environment – about the bacteria that affect oral and overall health. The experiment will travel to the orbiting laboratory aboard SpaceX’s 22nd commercial resupply services mission, (SpaceX CRS-22, contracted by NASA, in the Dragon spacecraft. It is scheduled to launch on or after 3 June 2021 from Kennedy Space Center in Florida.

“Colgate’s purpose is to reimagine a healthier future for all people, their pets, and the planet,” says Pat Verduin, chief technology officer at Colgate-Palmolive. “We constantly strive to push the limits of research and development – and now we’re pushing even further, into space. Our partnership with ISS National Lab and the University of Nevada – Las Vegas will help us go beyond what’s expected, beyond what’s known, and even beyond our planet to test and accelerate the science of oral health.”

The on-board experiment is designed to learn more about the growth and metabolism of oral biofilms, which in our mouths take the form of dental plaque that can lead to cavities and gum disease. To conduct the experiment on the ISS, the crew will use microfluidic devices developed by faculty from the College of Engineering at UNLV and Colgate’s microbiologists to simulate bacterial growth on a tooth-like surface. After more than a month of exposure to microgravity, the devices will be returned to Earth aboard the SpaceX Dragon spacecraft, and our scientists will analyse and compare results to matching control experiments conducted on the ground.

“This upcoming SpaceX mission to resupply the space station with critical supplies also includes research that brings value to our nation and enables a robust market in low Earth orbit,” says Michael Roberts, interim chief scientist on behalf of the ISS National Lab. “We welcome Colgate to the space station research community, and hope this is the first of many successful investigations launched by the company’s scientists to the unique environment of the orbiting laboratory.”

The company anticipates that the results of the mission could benefit more than half of the world’s population in the next five to ten years, as Colgate looks for new-found ways to create more effective therapies to fight disease, cavities, and anything that threatens oral health.

Going where no private oral care company has gone before, this is the first of several research projects in space that Colgate has planned in partnership with the ISS National Lab.

“This is one small step towards advancing oral health, and one giant leap towards furthering Colgate’s research and development centered around smart health solutions,” says Verduin.
