PEG-6, PEG-8, PEG-32, PEG-75, PEG-150, PEG-14M and PEG-20M are polymers of ethylene glycol. PEG is an abbreviation for polyethylene glycol. The number in the name is the average number of units, or monomers, of ethylene glycol. The letter "M" associated with the number stands for 1000, so PEG-14M has an average of 14,000 units of ethylene glycol.
PEG-6, PEG-8, PEG-32, PEG-75, PEG-150, PEG-14M and PEG-20M are used in a wide variety of products including bath products, shaving products, skin care products, makeup, skin cleansing products, shampoo, hair conditioners and deodorants.
The safety of PEG-6, PEG-8, PEG-32, PEG-75, PEG-150, PEG-14M and PEG-20M has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that PEG-6, PEG-8, PEG-32, PEG-75, PEG-150, PEG-14M and PEG-20M were safe for use in cosmetics and personal care products.CIR Safety Review: The CIR Expert Panel noted that in general, the PEG ingredients have a low order of oral and dermal toxicity. Lower molecular weight PEG ingredients were minimally absorbed and higher molecular weight PEGs (PEG-75 and greater) were not absorbed through intact skin. The PEGs were minimally irritating to human skin, and were not sensitizers. The available data indicated that the PEGs were not mutagenic or carcinogenic.
The Expert CIR Panel reviewed studies which reported kidney toxicity in severly burned patients treated several times each day with a PEG-based antimicrobial cream. The PEG content of the antimicrobial was determined to be the causative agent. However, no evidence of systemic toxicity occurred in studies with intact skin. Because of the observation of kidney effects in burn patients, the CIR Expert Panel qualified their conclusion on the safety of the PEG ingredients to state that cosmetic formulations containing these ingredients should not be used on damaged skin.
Small amounts of 1,4-dioxane, a by-product of ethoxylation, may be found in polyethylene glycol ingredients including, PEG-6, PEG-8, PEG-32, PEG-75, PEG-150, PEG-14M and PEG-20M. The potential presence of this material is well known and can be controlled through purification steps to remove it from the ingredients before blending into cosmetic formulations.
