“Not that one, Mom,” said Ted. “I don’t want that one. I’m not putting it on my hands. Buy this one.” Eva sighed. Had she been this picky as a kid? Was this what her mother had meant when she’d said that Eva would understand someday? “There’s nothing wrong with it, Ted,” she said. “What reason could you possibly have for not liking this hand sanitizer? They’re the same.” Ted took a deep breath. He was trying as hard as he could to be patient. Why didn’t his Mom get it? “That one was yellow last time,” he said. “It’s not supposed to be yellow. There’s something wrong with it. I don’t want to put it on my hands.” Eva looked at her watch. Ted’s little sister would be done with dance in 12 minutes. This wasn’t the time to be arguing in Walgreens. “Okay,” she said. “Fine. We’ll get the other one. Let’s go.”

Color consistency is an important facet of quality control for manufacturers of hand sanitizer. While a customer may not be aware that they are looking for a particular color of sanitizer, they are likely to notice if the product is not the color they expect it to be, compromising saleability and damaging brand reputation. As such, color measurement is an integral part of product quality control, helping manufacturers ensure their product meets customer expectations.

Instrumental Color Quality Control Ensures Consistency

To ensure consistently colored sanitizer from batch to batch, manufacturers turn to instrumental color measurement. Instruments are able to objectively determine the color of a product, with a much higher degree of repeatability than human observers. Manufacturers input their desired color or a range of acceptable shades. The instrument rapidly assesses the color of the sample, and compares it against the pre-determined standard. Rapid and accurate, this measurement guarantees that any off-color batches will be detected in time for manufacturers to take corrective action. Should repeated batches fail to meet tolerance standards, it can alert manufacturers that there is a problem with their process.

For measuring transparent liquid or gel products like hand sanitizer, the transmission spectrophotometer is the preferred instrument. These instruments measure the changes in the color of light that passes through an object. Built for industry use, they are durable, dependable, and long-lasting.
