The Nail Polish Of The Near Future
It's been only a couple of days since your manicure, and you're already bored with the shade. Don't you wish making a quick color change was as easy as waving a magic wand? Well, in the not-too-far-off future, it may be.
A team of chemists at the University of California recently identified a way to change pigments in a liquid. Made of the iron oxides commonly found in mineral makeup, the polymer-embedded pigments can be instantaneously and reversibly manipulated by a magnetic field. In other words, the nail polish that goes on coral could be shifted to a new shade-say burgundy, black or beige-and back again when exposed to a variable magnetic force. Conceivably, the technology could work on any liquid cosmetic made with iron oxide pigments, including lip gloss, foundation and more.
Although the researchers know they could impact cosmetics, their findings are likely to be applied to other industries, as well, such as electronic displays and paint.
In addition to this technology being both fun and convenient, it's also eco-friendly, as it would allow for less use of sometimes-toxic dyes.
