All functions
SD Alcohol 40-B


SD Alcohol 40-B is a blend of ethyl alcohol, or ethanol, with a denaturant. A denaturant is a bitter-tasting and/or poisonous ingredient that is added to ethanol used in skincare products to prevent recreational consumption.

In the case of SD Alcohol 40-B, the denaturant is denatonium benzoate, an extremely bitter compound. SD Alcohol 40-B is the active ingredient in many hand sanitizers, and it also serves as an astringent.

Beyond these two functions, it also makes an excellent solvent, as it dissolves a very wide range of other ingredients that would otherwise not be soluble together. It also controls viscosity by acting as a thinning agent.
