PEG-4 Dilaurate is a synthetic ingredient derived from lauric acid, a naturally occurring fatty acid found in coconut oil. It is used in cosmetics and personal care products as an emulsifier, solubilizer, and surfactant. It helps to form emulsions by reducing the surface tension of the substances to be emulsified. It also cleans the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away. PEGs are often contaminated with impurities such as ethylene oxide, 1,4-dioxane, polycyclic aromatic compounds, and heavy metals.

Avoid if skin is sensitive or damaged
PEG-4 Dilaurate has been associated with several potential side effects, including skin irritation, allergies, and organ system toxicity. In short-term feeding studies, PEG Laurate ingredients were irritating to the gastrointestinal tract, but not necrotizing. In chronic oral toxicity studies, there was some evidence of liver damage and hyperplasia in several tissues. PEGs may also enhance the penetration of other ingredients into the skin, which can be both beneficial and harmful depending on the ingredients used.
PEG-4 Dilaurate should be used with caution in individuals with sensitive skin or allergies. It should also be avoided by individuals with organ system toxicity.

Safe for use in cosmetics with some qualifications
Restricted
PEG-4 Dilaurate is a synthetic ingredient that is not naturally derived. Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in the PEG Dilaurate and PEG Laurate ingredients. PEGs can also be contaminated with other impurities such as ethylene oxide, polycyclic aromatic compounds, and heavy metals.
