A humectant that attracts and holds water.

What it is

Glycerin (glycerol) is a small polyol molecule that binds water. It can be obtained from plant oils, animal fats or synthetic processes; the INCI name does not say which.

Where it is used

Used in moisturisers, serums, cleansers, toothpastes and many other products as a humectant and solvent.

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 label does not reveal the source of glycerin (plant, animal or synthetic).
