Isopropyl alcohol, also known as isopropanol, is a clear, colorless liquid that is soluble in water. It has a strong alcoholic aroma and is widely used in the production of perfumes, cosmetics, and other personal care products due to its excellent solubility and volatility. In addition, isopropyl alcohol is also used as a solvent in the production of paints, adhesives, and other products.

When used in the production of adhesives and other products, it is often necessary to add water to the isopropyl alcohol to adjust its concentration and viscosity. However, adding water to isopropyl alcohol may also cause some changes in its properties. For example, when water is added to isopropyl alcohol, the polarity of the solution will change, affecting its solubility and volatility. In addition, adding water will also increase the surface tension of the solution, making it more difficult to spread on a surface. Therefore, when adding water to isopropyl alcohol, it is necessary to consider its intended use and adjust the proportion of water according to the requirements.

If you want to know more about isopropyl alcohol and its uses, it is recommended to consult professional books or consult relevant experts. Please note that due to the different properties of different products, it is not possible to know the specific information simply by adding water to 99% isopropyl alcohol without relevant experience and knowledge. Please make scientific experiments under the guidance of professionals.
