Methylpropanediol

Methylpropanediol is a unique glycol that contains two primary hydroxyl groups. The presence of these two primary hydroxyl groups has a few advantages.

First, the physically unhindered nature of these chemical groups allows them to bind to water very readily. This results in methylpropanediol being able to act as a powerful humectant, which is a type of moisturizer that draws water into the outer layers of the skin.

Second, the presence of the hydroxyl groups on a short carbon chain makes this ingredient an excellent solvent. It is capable of dissolving a wide range of polar ingredients to combine otherwise incompatible ingredients.
