Osmolality testing has unlimited applications in areas of personal care and hygiene. Products that come into contact with or penetrate the skin must have an osmolality within a physiological range to avoid damaging cells and tissues. In some instances, slightly hypo- or hyper-osmotic solutions are generated to promote wetting or drying effects. The manufacturing of skincare products, personal lubricants and optical products
One key to a youthful look is healthy and moisturized skin. Proper hydration of skin depends on a balance of water flow into and out of skin cells and, thus, depends on osmolality. Osmolality testing of skincare products provides assurance that the product will have moisturizing effects and serves as a control during the production process.
The osmolality of personal lubricant formulations impacts their effect and safety. The World Health Organization (WHO) stated that the osmolality of these solutions should not exceed 1200 mOsm/kg, with this limit decreasing to a more iso-osmotic level in the future.
Similar value for osmolality testing can be clearly seen in optical applications. Eye drops and other optical products are designed to lubricate or protect the eye. The goal of these solutions (e.g. adding moisture, removing moisture, etc.) dictates an ideal osmolality range.
