A high-molecular polyethylene glycol used as a binder, stabiliser and solvent.

What it is

PEG-400 is a polymer of ethylene oxide (polyethylene glycol) with an average of 400 ethylene oxide units. CosIng lists it as a binding, emulsion-stabilising and solvent ingredient. It is a synthetic ingredient.

Where it is used

Limits of interpretation

The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.

The INCI name PEG-400 does not correspond to the commercial grade called PEG 400, which is named PEG-8 in INCI; the number refers to the average chain length, so the raw material is a mixture.
