What is Propanediol?
Propanediol is a colorless liquid that is naturally derived from corn sugar or corn glucose. It's also made synthetically in a laboratory and added to a variety of personal care products. This ingredient is fully dissolvable in water and helps to create a consistent, uniform solution when combined with water. The chemical makeup of propanediol consists of alkaline and diol, which means that a chain of carbons and hydrogens attached combine with diol, a form of alcohol.
What is Propanediol in Cosmetics?
Propanediol acts as an emollient and a humectant, which means that it helps to add nourishing moisture to the skin while reducing moisture loss. This is a great way to help improve your skin texture, and that's why it may be included in a wide range of cosmetics. Some examples include makeup primers, BB and CC creams, and foundations.
Propanediol in skin care
There are many reasons why propanediol is used in skin care products. It is an excellent solvent, so it helps to dissolve other ingredients in the product you use for optimal application. It works great when used with anti-acne products containing salicylic acid, for example, since it helps this important ingredient deliver to the skin more effectively. It also helps to make products more fluid. Items that have a sticky or tacky feel will be much smoother and easier to apply when propanediol is added to the mix.
