Agrocer® – Seed Coloration
Colorants for Seed Treatment, Fertilizer and Crop Protection
Clariant offers a dedicated range of powder pigments and pigment preparations (aqueous dispersions based on pigments) as well as selected dyes (Sanolin, Duasyn) for seed coloration. Additional products are offered in the regions, and tailor-made products are available on request.
Colorants for Seed Treatment
AGROCER is Clariant’s brand for pigments and pigment preparations for the coloration of seed.
The range is based on the six most globally significant color indices used in this application field and all global products are exempted from the requirement of a tolerance under U.S. EPA 40 CFR §180.920 and are cleared to be used on crops for food use. The products are also compliant with the European REACH Regulation.
The coloration of seeds, which are treated with pesticides is mandatory in most legislations to avoid misuse. Besides this important safety feature, there are other important aspects such as individual colors and color shades for branding, identification of a specific treatment between different seed varieties, easy monitoring of uniformity and consitency of seed treatments or value perception and cosmetic appeal for high-value seeds.
Agrocer products are manufactured without nonylphenol ethoxylates (NPE), alkyl phenol ethoxylates (APE), and are free of hazardous labeling. The products have been tested for seed safety and do not show a negative impact on germination.
Colorants for Fertilizers
Plants require more than a dozen nutrients for optimum growth. Fertilizers supply the most essential nutrients to plants. Clariant provides pigments, pigment preparations and dyes for fertilizer colorations, helping to differentiate qualities and applications.
Colorants for Crop Protection
Clariant offers selected dyes (Sanolin, Duasyn) for crop protection products.
Six basic pigments – endless color variations
Color has always been used as a branding and marketing tool in various application fields. And, more seed companies and professional seed coaters are looking for new color options to optically differentiate their products. Clariant’s Agrocer colorants are available in the most relevant color indices that can be blended to make a variety of custom colors. Combinations of the different pigments or pigment preparations can be used to generate a virtually indefinite number of individual color shades. The addition of white, black or pearlescent pigments adds further options to fine-tune the appeal of a seed coating. For example, Agrocer White 006 Disp. adds hiding power and enhances the coverage of seeds.
Powder Pigments for seed coloration
Agrocer powder pigments are easily dispersible, exhibit a high color strength and show good hiding power, which is important to achieve good coverage on various types of seeds. The brand names of the Agrocer products include the color and a three-digit figure based on the underlying color index.
Agrocer powder pigments are the preferred solution for seed treatment pesticide formulations in which a high pigment loading is required and where no additional water can be introduced into the formulation. In order to utilize the full potential of these products, the pigments need to be dispersed properly, using appropriate equipment.

Pigment preparations for seed coloration
Agrocer Disp. pigment preparations are aqueous dispersions based on the Agrocer pigments. Compared to powdered pigments, Agrocer pigment preparations offer fast and more cost-efficient production to agrochemical, seed and seed treatment companies, and for on-farm seed treatment looking for safe, regulatory-compliant solutions for eye-catching, high-value products. All Agrocer Disp. pigment preparations show excellent compatibility with seed treatment pesticide formulations as well as seed coating products. The preparations are based on wetting and dispersing agents as well as other additives, which are commonly used in seed treatment pesticide formulations.
Clariant's Agrocer seed colorants are now available in pre-dispersed granulated pigments with a very small particle size making them easy to disperse in cold water. The new pre-dispersed granules flow like liquid, can be metered and are suitable for applications where a dust-free dry stir in process is needed. The new granulated formula requires minimal storage space.
