LiquiGlide, a slippery coating for the inside of bottles, could save “one million tons of food from being thrown out every year,” according to MIT Ph.D. candidate Dave Smith. Smith, along with a team of mechanical engineers, created the substance that would allow ketchup, mayonnaise, mustard and other condiments to slide easily and completely out of a bottle.


The tons of food saved are the remnants of condiments that stay in the bottle — despite consumers' best efforts to scrape, shake and smack the ends out of the bottle.



The team made sure that the materials in the LiquiGlide are food safe, at least according to the Food and Drug Administration. But, the FDA also says that bisphenol-A (BPA) and artificial food dyes are food safe, and there’s plenty of evidence to suggest otherwise. Just because the FDA says something is safe to ingest in our bodies, doesn’t mean it is.


One question that should be asked here — since the materials in LiquiGlide aren’t being revealed by the creators; Is the prospect of less food waste worth the risk of contaminating our food with an unknown product? I don’t know; I don’t have enough information, but it’s certainly something to question.


I first saw this story on Co.EXIST, and like many online stories, this one is worth reading, especially the comments that follow the article. Some people have the same question I do, “Is it really safe for food?” Others wonder what other applications this super slippery coating could have. Could it stop soap scum and toothpaste from building up on a bathroom sink? If they used it shampoo bottles, would the chemicals in the coating harm your hair? Could it coat PVC fixtures and stop drains from being clogged?


If the materials in LiquiGlide really are safe, then this product could stop a lot of waste, and if it really could coat PVC fixtures, could stop a lot of drain-clearing chemicals from being dumped into the water supply.


It’s certainly worth keeping an eye on to see what happens with the product.
