This eco-approach that we have undertaken is applied (modus operandi) in the management of obtaining our raw materials.
We require our suppliers to use raw materials that have a good track record with respect to the soil. Each raw material, for example, is accompanied by a certificate of analysis which must comply with ecological standards for pesticides and heavy metals, etc.
It is quite normal to notice, from time to time, small shades of color resulting from the marriage of our components. Nature is labile (unstable) in color.
This in no way affects the quality of the product on the contrary!
