To convert Glycerin 85 to Glycerin 98, one can use a process called distillation. Distillation involves heating the Glycerin 85 to its boiling point, allowing it to vaporize, and then condensing the vapor back into a liquid form. This process separates the Glycerin from any impurities or water, resulting in a higher concentration of Glycerin. By repeating the distillation process, one can continue to increase the concentration of Glycerin until reaching the desired 98% concentration. **

Yes, glycerin can evaporate. Glycerin is a hygroscopic compound, meaning it can absorb moisture from the air. When exposed to air, glycerin can slowly evaporate over time. However, glycerin has a relatively low evaporation rate compared to other liquids like water, so it may take longer for glycerin to fully evaporate. **

Glycerin is a versatile ingredient that can achieve several benefits for the skin. It is a humectant, meaning it attracts moisture to the skin and helps to keep it hydrated. Glycerin also helps to improve the skin's barrier function, making it more resilient to external aggressors. Additionally, glycerin has emollient properties, which can help to soften and smooth the skin, making it a popular ingredient in skincare products. **

Glycerin is a common ingredient in many food products and is generally recognized as safe for consumption by regulatory agencies like the FDA. However, consuming large amounts of pure glycerin can have a laxative effect and may cause gastrointestinal discomfort. It is best to consume glycerin in small amounts as part of food products rather than on its own. **
