In 2001, NASA sent the science behind toothpaste and salad dressing into space; the research later helped produce three P&G patents

Since 2001, NASA has explored the behavior of colloids aboard the International Space Station, where the lack of gravity permits intricate study of how particles separate and settle. This pioneering research, in collaboration with Procter & Gamble, has led to the development of three patents aimed at enhancing the stability of everyday products, ensuring improved consistency in items ranging from toothpaste to salad dressings.
