NBT Naturals – 1.3 Propanediol

Propanediol is a popular ingredient used in cosmetic and skin care products. 1,3-propanediol is a colorless and odorless liquid that is very effective and is a low-cost ingredient. Propanediol is a humectant as well as an emollient which means that apart from adding moisture to the skin, it also reduces moisture loss from the skin. Additionally, it is an excellent solvent and dissolves all the other ingredients in a formulation.

Usage rate:– 1–20%, though I find it can feel draggy beyond 3%—this does depend on the formulation.

Solubility:- Water
