P&G’s Tide is headed to space

Tide, the detergent used by millions across the United States, wants to make lunar laundromats a thing.

Parent company Procter & Gamble Co is working with the National Aeronautics and Space Administration on a formula that can withstand conditions off-planet so astronauts can do laundry while on missions.

The first shipment made its way to the International Space Station on a SpaceX rocket on Dec 21, and its performance is undergoing tests.

Astronauts wear clothes several times, replacing them with new apparel delivered on resupply missions. But spacecraft have limited cargo capacity, and replenishment dispatches aren’t possible on longer trips to far-flung locales such as the moon or Mars.

That makes laundry one of many questions for scientists to answer as demand for space travel heats up.

“There’s no effective laundry solution that exists in space,” said Marc Pritchard, P&G’s chief brand officer on Wednesday.

Mundane on Earth, washing clothes faces several hurdles in space. One is that each load relies on a small amount of water, which then needs to be purified back into something astronauts can drink.

P&G developed a fully degradable Tide detergent that aims to meet that challenge, and the company hopes the experience will inform the development of more sustainable cleaning products back home.

The process will be optimised to use about 15 litres of water for a 10-pound load of laundry, according to P&G, compared to roughly 49 to 77 litres when washing at home.

“This innovation will not only advance cleaning solutions in space but for resource-constrained environments, like water-scarce areas on Earth,” Pritchard said.

For smaller stains that befall astronauts, P&G is also testing Tide To Go Pens and Tide To Go Wipes in a microgravity environment.
