Keeping it Fabulous: Spectrophotometry Shines In Cosmetic Quality Assurance

When it comes to cosmetics, color is everything. Whether you are looking for a dramatic smoky eye shadow, or enhance your natural skin tone a shade lighter or darker can change the entire look. In fact, most cosmetic consumers will find a color palette they like and continue to purchase colors that work best for them. That is why repeatability in cosmetic production is vital, as it will increase both brand loyalty and sales.

Precise color measurements is key to achieving consistency in cosmetic production. Often, basic visual analysis is the first step to confirm that a color shade is in the same ballpark as the hue in production. Unfortunately, not only is visual inspection a very limited method for ensuring color quality, the different shine and textures of some powdered cosmetics can make discerning the exact hue difficult.

To solve this problem use a color measurement instrument to create a quantifiable numeric value. Sphere-based spectrophotometric technology, found in instruments like the CM-700d Spectrophotometer, are the best way to ensure colors are within the acceptable tolerance. With spectrophotometers manufacturers can quantify color using the CIE L*a*b color space. Color tolerance can also be easily established by using the ΔE*ab color difference formula, or the more modern CIE 2000 (delta E00), some high-end manufactures may have their own standards for all their suppliers and subsidiaries to comply.

Applied at multiple points throughout the stages of development and manufacturing to make sure the color remains consistent through each step Spectrophotometry is a versatile quality control method.

Overall, spectrophotometry is preferred in the cosmetic industry because it confirms the data obtained with visual inspection and quantifies it numerically, which reduces potential color errors early on in the process. This saves cosmetic manufacturers valuable time and money while securing them a consistent, high-quality product with a high resale value at the outset.
Of course, color measurements are only as accurate as the instruments used to make them. Konica Minolta is an industry leader in top-of-the-line color measurement instruments like the CM-5, the CM-700d, and, CM-3700A. Such highly accurate instruments are able to deliver precise color measurement data for manufacturing applications within the cosmetic industry keeping cosmetic consumers looking fabulous.

In addition to instrumentation, Konica Minolta also has a suite of software for Quality Control and Color Formulation. Combining these software products with color instruments provides all departments in the cosmetic industry with highly accurate and traceable data to control color through the production process.
