Scientists investigated how temperature and concentration affect the physical properties of liquid mixtures containing panthenol, a form of vitamin B5 commonly used in skincare products. They mixed panthenol with propylene glycol and hexylene glycol, which are humectants that help products retain moisture, along with water. By measuring how these liquids behaved at different temperatures ranging from about 50 to 113 degrees Fahrenheit and at varying amounts of panthenol, the researchers could understand how the different ingredients interact with each other at the molecular level. They used specialized techniques to measure how dense the liquids were and how sound traveled through them.
The findings showed that these interactions change significantly based on temperature and how much panthenol is present. This research provides useful information for companies developing cosmetic, food, and pharmaceutical products that rely on panthenol and glycol-based ingredients, helping them optimize formulations for better performance.
