PEG-7 Glyceryl Cocoate Goed Reinigingsmiddel Hydratatie PEG-7 Glyceryl Cocoate at a glance Emollient, surfactant, and emulsifier that’s partially derived from coconut Often used in moisturisers, hair conditioners, and cleansers Purification process helps control any potentially dangerous byproducts Deemed safe as used in cosmetics PEG-7 Glyceryl Cocoate description PEG-7 glyceryl cocoate is a complex blend of a polyethylene glycol (PEG) derivative and coconut + glycerin-derived cleansing agent, meaning that it can be described as coconut-derived. The blend can be an emollient, emulsifier, and surfactant. As an emollient, it helps soften and smooth skin, making it a useful addition to moisturisers, hair conditioners, and cleansers. There have been some concerns about the safety of this ingredient because of the presence of ethylene oxide in it. Ethylene oxide can react with other chemicals in a process called ethoxylation, which can lead to contamination by 1,4-dioxane, a dangerous byproduct. This byproduct can be eliminated through controlled purification processes, which is how cosmetic PEG-7 glyceryl cocoate is produced. The Cosmetic Ingredient Review panel has ruled that PEG-7 glyceryl cocoate is safe as used in rinse-off products and is safe in leave-on products in amounts up to 10%.
