Our PURE Color nail polishes are 84% bio-based. What does that mean? We’ve replaced solvents derived from petrol or natural gas (yuck!) with plant-derived solvents (that’s more like it!). So, we use solvents made from natural origin raw materials such as cotton, maize, potato, wheat and manioc. What about the remaining 16%? This allows the polish to retain its easy application, shine and hold with natural and/or organic pigments (depending on the shade), filmogenic agents and plasticizers. It’s part of a necessary, controlled and accepted compromise. As a plus: our polishes are enriched with plant keratin and starflower oil to nourish nails.
