Namely
PEG-100 Stearate is an ester of Polyethylene Glycol and Stearic Acid. The origin of this synthetic ingredient is therefore a plastic material. It is used mainly in cosmetics as emulsifier, emollient and surfactant. It is in the form of a soft solid of white to beige color. In addition to its cleaning capabilities, it gives products a velvety texture.
Due to its ethoxylation pollutant production, PEGs and their derivatives are banned in organic form.
In a study published in the journal Toxicology in 2005 titled "Assessment of the safety of polyethylene glycols (PEGs) and their derivatives in cosmetics", it was concluded that: "Taking into account all available information from On the basis of the available data, it is therefore concluded that PEGs from a wide range of molecular weights (200 to over 10,000), their ethers (laureth, ceteth, ceteareth, steareth and oleth) and fatty acids (laurate, dilaurate, stearate, distearate) are safe for cosmetics. "
However, according to other studies of the same newspaper, it is also mentioned that PEG may contain impurities harmful to health including ethylene oxide, 1,4 dioxane, iron, hydrocarbons polycyclic aromatic hydrocarbons (PAHs) or arsenic. It is advisable to avoid this type of ingredient if you have sensitive skin.
