WHAT IS IT?
Water permeable polish is made from a formulation which allows oxygen molecules to transfer from one side of the nail polish layer to the other. This occurrence happens only on a molecular level and is not visible to the naked eye, making DIY checks inaccurate. Tests have shown that if oxygen can permeate a nail polish film, then hydrogen atoms attached to the oxygen can also travel with it to the other side of the film. This action enables water to transfer from one side to the other, hence making the nail polish water permeable and breathable.
WHY CHOOSE WATER PERMEABLE?
Using water permeable nail polish can help to improve the health of your nails and the quality of your manicure. This new and improved base allows nails to behave naturally and grow without the restrictions of non-breathable polishes. This has also made the product available to a wider market of consumers, including Muslim women who choose to wear water permeable polish.
HOW IS IT TESTED?
A nail polish film sample is put inside a diffusion chamber which separates the top half of the chamber from the bottom (as seen in figure 1.0). Oxygen then flows into the top half of the chamber and an oxygen-free carrier gas (i.e. nitrogen) flows into the bottom on the other side of the film. Once the oxygen permeates the nail polish film, we know that the polish is breathable. The experiment is carried out according to ASTM D 3985 and ISO 15105-2 standards. These exacting standards have far greater technical relevance than the coffee filter paper test, which is a highly inaccurate representation of the chemical reaction.
WHY HAS KESTER BLACK MADE WATER PERMEABLE NAIL POLISH?
We have an ongoing vision to improve the quality of all of our products wherever possible. Not only have we improved the quality of our nail polishes, but we’ve also made them available to Muslim women who choose to wear breathable, water permeable nail polish.
