Diglycerin
Diglycerin is a dimer of glycerin (chemically: Oxybispropanediol, CAS 59113-36-9 / 25618-55-7) and is classified as a skin-identical ingredient. It has a larger molecular structure than glycerin, which causes it to penetrate the skin more slowly. It functions as both a humectant and a skin-conditioning agent according to CosIng.

humectant● Benefits
Diglycerin is a natural moisturizing factor that reduces water evaporation from the upper layer of the skin and helps retain moisture, keeping skin hydrated. Compared to glycerin, its larger molecular structure provides longer-lasting moisture and a less sticky, improved skin feel.
