7-free, 10-free, 12-free nail polish explained

Nail polish has something of a dubious reputation when it comes to the ingredients list. A lot of conventional nail polish still contains some pretty dodgy stuff. Formaldehyde, anyone? Us neither.

When non-toxic nail polish arrived to support our health, planet and our manis, the X-free branding of nail polish was developed to show people the number of chemicals a polish is free from. But over time, this has turned into something of a marketing arms race. With no cosmetic governing body, the X-free labelling got out of hand very quickly, with some companies even including animal products in their ‘free from’ list.

We decided to step back from the brouhaha and let our formula do all the talking. We are confident our polish is the cleanest AND will give you a durable manicure. But don’t just take our word for it. We are certified by Made Safe who have analysed every single ingredient and deemed us the cleanest.

Sienna nail polish has always been free of Formaldehyde, DBP, Toluene, Tosylamide/Formaldehyde Resin, Synthetic Camphor, Xylene and Benzophenone -1.

In the name of our commitment to full transparency, we list all the ingredients in our products on our FAQ’s.

It is worth mentioning that Sienna polish has never contained Benzophenone-1, a known endocrine disrupter. Some of the polishes labelled X-free still include it in their formulas, so when in doubt, check the ingredients list.
