Diglycerin and Exfoliation

You've observed that Diglycerin is listed under the "Exfoliant" category on the website and are asking if it can act as an exfoliant in addition to being a humectant.

Based on the information available, Diglycerin is primarily known and used for its properties as a humectant. It functions similarly to glycerin, helping the skin retain moisture, and is often preferred for its potentially better moisture retention efficiency. It can also act as a foam booster in soap formulations.

Diglycerin does not possess the chemical or physical properties that would classify it as an exfoliant. Exfoliants work by removing dead skin cells from the surface of the skin, either through chemical action (like AHAs or BHAs) or physical abrasion. Diglycerin does not perform this function.

It appears there might be a categorization error on the website, as Diglycerin's role in formulations is related to hydration and texture, not exfoliation.
