INCI name

PEG-7

A low-molecular polyethylene glycol used as a humectant and solvent.

What it is

PEG-7 is a polyethylene glycol, a polymer of ethylene oxide with an average of 7 ethylene oxide units. At this chain length it is a liquid. CosIng lists it as a humectant and solvent.

Where it is used

Found in toners, gels, serums, cleansers and other water-based products.

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 number 7 refers to the average number of ethylene oxide units, so the raw material is a mixture of chain lengths.

Functions

Humectant: Retaining and/or preserving the moisture in a product during use.
Solvent: Dissolving other components of cosmetics. Solvents are usually liquids (aqueous and nonaqueous).
