Propylene Glycol Dibenzoate



Propylene Glycol Dibenzoate description

Propylene glycol dibenzoate is a diester combination of the humectant propylene glycol and the preservative benzoic acid. A diester is a chemistry term that means an ingredient formed from two separate esters, resulting in an ingredient that has a different form and result. In this case, combining esters of propylene glycol and benzoic acid results in a fluid ingredient that works as a lightweight emollient to soften skin and helps prevent moisture loss. Propylene glycol dibenzoate is a synthetic ingredient that is sometimes used as a silicone replacement. Due to its high refractive quality on skin, it works well to reflect light, creating the look of a healthy glow.
