Predosed laundry detergent innovations are making waves, so I wanted to talk about a particularly cool one and the science behind it: Nellie’s laundry cubes! Nellie's Clean
These laundry cubes don’t dissolve, they disintegrate!!! Citric acid + sodium bicarbonate react on contact with water, releasing CO2 that fizzes and cracks the cube apart from the inside out.
That’s why it breaks up fast: not agitation or heat wearing it down, but a real acid-base reaction doing the work so the surfactants and enzymes can get to your laundry.
Let me know what you think in the comments
