What are PEG/PPG?

Polyethylene glycols (PEG) and polypropylene glycols (PPG) are humectants (which help retain or preserve moisture) or emulsifiers that can be found in many cosmetic products.

What are PEG ?

To identify them in our products, take a look at the ingredients list on packaging. They can usually be found by names starting with PEG- or PPG-.

What are they used for?

What are they used for?
  • Mainly used as emulsifiers to homogeneously mix ingredients that are normally immiscible such as water and oils

  • Also used as thickening or gelling agents

  • Key ingredients in cosmetic products also used as a food additive in certain food items (E1521)

Why are they questioned?

They are accused of being carcinogenic, of being toxic to the liver and kidneys and of causing allergies. They are also suspected of being toxic for the environment. 

●    PEGs present no risk for health. They have been used in the medical field for decades.

●    According to the general opinion of scientists and health authorities, PEGs are well tolerated by the skin: they do not present any allergenic potential at their concentration level in our products. PEGs can be irritating if used pure but present no risk in formulas when used in low concentrations.

●    They are not toxic to the environment, yet they are not biodegradable.

Why and how do we use them?

  • PEGs and PPGs allow to formulate products of many different kinds of textures. Their diversity makes it possible to offer products with various sensorialities and which are adapted to each type of skin.

  • In a process of continuous improvement, we are working closely with our suppliers to improve the production process of PEGs and PPGs and their impact on the environment.
