Powder Color Measurement

Powdered chemicals are used across many industries including coatings, food, building materials, pharmaceuticals, cosmetics and cleaning materials to name a few. Whether you are measuring the white of calcium carbonate, the blue of copper benzoate, the green of nickel chloride or the deep magenta of cobalt chloride hexahydrate, HunterLab has been providing color measurement solutions for the chemical industry for over 60 years, and many of the world’s leading chemical manufacturers rely on HunterLab solutions to ensure quality and consistency of the raw materials used in their products throughout their supply chain.

The color of powders such as limestone or raw pigment powders are often measured as an incoming QC check to ensure lot-to-lot consistency of raw materials, and to ensure color accuracy of the final product, such as cosmetic facial powder or baking powder.


The preferred method for measuring powders is to use a Directional  45°/0° reflectance geometry for its ability to measure color the way the human eye ‘sees’ color. This is the geometry that is recommended by HunterLab for color measurement of opaque materials that will be viewed by the customer.

Many of HunterLab’s spectrophotometers are versatile enough to accommodate most applications of color measurement. However, based on 60+ years of experience and a thorough understanding of our customers’ needs and product use, these particular instruments are most suited for this industries application.
