What is usp alcohol mean?

USP alcohol is ethyl alcohol that meets the standards set by the United States Pharmacopeia (USP). The USP is a compendium of standards for medicines, including their purity, strength, and quality. USP alcohol is used in a variety of pharmaceutical and personal care products, including hand sanitizers, antiseptics, and medications.

To meet USP standards, ethyl alcohol must be at least 95% pure and free of impurities such as methanol, acetone, and benzene. It must also be free of color and odor. USP alcohol is typically denatured with a small amount of a denaturing agent, such as methanol or isopropyl alcohol, to make it unfit for drinking.

USP alcohol is used in a variety of applications where a high-quality, pure alcohol is required. In pharmaceuticals, it is used as a solvent, preservative, and disinfectant. In personal care products, it is used as an astringent, antiseptic, and deodorant. USP alcohol is also used in the food industry as a flavoring agent and preservative.

Because USP alcohol is a flammable liquid, it should be handled with care. It should be stored in a cool, dry place away from sources of heat and ignition. USP alcohol should also be kept out of the reach of children.
