Laboratory for the analysis of organic and inorganic color pigments
Colored pigments: they make you see all the colors?
REACH registration: a guide for registrants
As part of REACH 2018 registrations, the Color Pigment Manufacturers Association (CPMA) is providing a document listing inorganic pigments by composition and manufacturing process to guide potential registrants – paint, stain, pigment manufacturers – in identifying and registering their substances.
The regulation states that any substance present at more than 10% of the total concentration must be mentioned in the name of the registered pigment.
Industrial companies are required to ensure that all substances used in their production process have been registered and accepted under REACH, in order to validate the compliance of the product before it is put on the market.
Problems with colored pigments: FILAB's expertise at the service of manufacturers
In the industry, a pigment is a chemical coloring substance used in liquid or powder form, for its opacifying and coloring power. A pigment can be of mineral, organic, synthetic or natural origin. They are used in the construction, cosmetics, fashion and decoration industries.
Each pigment is associated with a name and a number according to its chemical composition, listed in the international index of colors.
The development of the industrial dye industry has complicated the compositions and analysis of pigments in a substance or material. The synthetic elements are most often derived from chemical mixtures of which some molecules may be classified as toxic or be concerned by specific regulations (eg: cadmium, white ceruse …).
Thus, chemical analysis performed on colored pigments can have different uses:
1. Determination of the elements present in the organic and inorganic pigments to verify that their content is in conformity with the regulations.
2. The search for specific impurities that can disturb the final performance of the product (adhesion, homogeneity, opacity…).
3. The study of substitution elements for molecules classified as toxic to meet new regulations.
At FILAB, we have a wide range of analytical equipment for the analysis of organic and inorganic color pigments, including the following techniques
ICP for the analysis of the chemical composition of colored pigments
X-Ray Diffraction (XRD) is also relevant to study the crystalline structure of the pigment and to determine the content of the different compounds observed.
Finally, Scanning Electron Microscopy (SEM FEG EDX) can be used to analyze the homogeneity and distribution of colored pigments in powder form on the sample.
The contribution of a chemical expertise laboratory allows you to optimize the use of your colored pigments, by ensuring their compliance with the regulations and REACH registrations. Do you want more information about our services? Contact us for more information!
