Sometimes the term natural dye can be a misnomer, as “natural” is not always the same as “non-toxic.” Many natural dye recipes rely on heavy metals such as lead and copper to bring out the plant based colors; such metals are both hazardous to the people working on them as well as the ground they are often dumped into.

While tonlé uses some natural dyes in our production, all of our natural dyes are inert, non-toxic, and 80% in fact come from edible materials like soymilk and lemon.
