Pigments are essential in cosmetics: in eyeshadows, nail polishes, and lipsticks ... They give a unique dimension to the face thanks to their subtle nuances and haunting colors.
However, there are pigments and pigments! While synthetic pigments have taken over since the twentieth century and raise more questions, natural pigments come back in strength. Support them!
Natural pigments for an organic make up
Pigments are solid molecules that bring color and nuance to a liquid or solid preparation. Pigments are found both in cosmetics and in murals.
In the great family of pigments, we find:
• mineral pigments (from precious or semi-precious stones such as cinnabar or azurite);
• organic pigments (from living matter such as plants, flowers);
• metallic pigments (from iron, copper, etc ...);
• Chemical pigments (composed of elements such as carbon, lead chromates, zinc oxides, titanium dioxides, cadmium sulphide, or iron oxides to obtain all the desired colors).
Watch out for artificial pigments
The development of organic chemistry has led to the creation of synthetic organic pigments at the expense of natural pigments. Yes, it is the petroleum chemistry, and more precisely the derivatives of aniline, which has led to the very marked appearance of pigmentary shades!
These synthetic dyes are easy to produce, cheaper, mix well with various ingredients and have an amazing covering capacity. But the use of synthetic pigments raises for some years deep concerns about their dangerousness.
These pigments are extracted from ores or from industrial waste, then undergo several modifications to obtain the desired colors. For iron oxides, it is the degree of calcination temperature that allows the hue variations.
Lipsticks, for example, are very rich in synthetic pigments. For experts, tar derivatives are carcinogenic, and can cause allergies instantly. Not to mention acid dyes with eosin which can cause photosensitivities in particular.
Prefer natural pigments
One of the fundamental principles of organic makeup is to use only dyes and components of natural origin. That's why rigorously selected ingredients come into their composition. The bio prohibits among others the azo dyes, pigments used in Europe in the manufacture of the classic make-ups, whereas they are proscribed in the United States.
Naturally, natural pigments offer a more limited range of colors and shades compared to conventional cosmetics, but creativity continues to serve the natural world to create larger ranges.
Indeed, although the manufacturers of natural makeup only benefited from iron oxides and some natural dyes, more and more of them offer a wider range of colors, whether for powders, lipsticks, eye shadows or mascaras. Let's enjoy while protecting our health!
