Very simply put, osmolality is a measure of how much one substance has dissolved in another substance. This is the exact type of information product researchers, developers, manufacturers, QC, QA, want to ascertain, especially when it comes to drinks, functional beverages, water, gels, creams, ointments, and just about any topicals. But osmolality measurement isn’t just useful information, there are certain products such as personal lubricants where the FDA actually requires osmolality testing.
So, why test products for osmolality? Osmolality testing is key to understanding and optimizing absorptions, purity, stability, characterization, shelf-life, and more. These variables are critical to overall product quality and consistency. Anyone with questions about a product’s potential behavior should look to osmolality.
