Dipropylene Glycol

Low risk

FunctionSolvent

What it is — Dipropylene Glycol (INCI: Dipropylene Glycol) is a solvent and formulation base.

What it does — It is commonly used as a humectant and solvent that helps dissolve other ingredients.

Typical use — It is a foundational component across almost every water-based category, carrying and dissolving other ingredients. How much is present depends on the format, from watery toners to richer creams.

Who it suits / good to know — Broadly compatible and non-active. It functions as part of the base rather than as a performance ingredient. There is little to react to here; it is essentially the carrier for everything else.

Safety — DHALIORA grades it low risk: widely used, low-irritation solvent. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.

Why we grade it Low: Low risk — widely used, low-irritation solvent.
How grades are set — Risk reflects our own reading of publicly available safety data, an EWG-style reading shown at the worst-case grade we've assigned this ingredient across products. It isn't a third party's proprietary score, and it isn't medical advice. Always read the packaging and patch-test where indicated.
