New scientific method to analyse detergent efficiency published in Tenside Surfactants Detergents journal

Biolin Scientific announce today that study results for a new scientific method to evaluate and rank the cleaning ability of new detergent formulations have been published in the journal Tenside Surfactants Detergents (TSD).

A paper entitled ‘Revealing Detergent Efficiency and Mechanism by Real-Time Measurement Using a Novel and Tailored QCM-D methodology,’ has been published online ahead of print in TSD.

The publication covers a recently completed study using Quartz Crystal Microbalance with Dissipation (QCM-D) technology to determine how to scientifically and rapidly screen detergent formulations in real-time. The study was performed by scientists at Biolin Scientific AB in Sweden in collaboration with the Center For Testmaterials in the Netherlands.

The scientists screened nine (9) commercially available dishwashing formulations and ranked them based on their ability to remove/swell standardized cooking grease soiled onto a silica surface. All measurements were performed using the Q-Sense Pro instrument.

The study showed that by combining three QCM-D cleaning parameters - cleaning rate; swelling time; and overall mass removal – a ranking of the screened detergents is easily achieved.

Biolin Scientific's Vice President for Analytical Instruments, Johan Westman, comments,

“Detergent manufacturers worldwide are still struggling with old-fashioned ways to measure how effective their products are. We are delighted that the results from this study have been published in a well-known, peer-reviewed journal. They add to growing evidence that QCM-D is a powerful technology that detergent manufacturers can benefit from, in real-time, to scientifically understand how clean and how fast their detergent formulations work.”
