Our Philosophy

Spotlight on the ingredients

Sugar cane

We extract the ingredient ethyl acetate from cane sugar, which forms the basis of the polish and gives it its liquid texture. 


We extract the ingredient butyl acetate from cassava, which forms the basis of the polish and gives it its liquid texture.


We get the ingredient nitrocellulose from cotton, which helps the polish form a solid film on the nail.


The ingredient acetyl tributyl citrate is extracted from corn. It helps the polish create its smooth, shiny coat on the nail.
