Olive Oil PEG-7 Esters description

Olive oil PEG-7 esters comes from a process known as transesterification, where pure olive oil is combined with PEG-7, a synthetic humectant and solvent. Transesterification is an eco-friendly chemical conversion where fatty acids such as triglycerides react with alcohol and other esters to form a new compound that is water soluble despite being made from an oil. In skin care products, olive oil PEG-7 esters works as an emollient, emulsifier, and mild, secondary cleansing agent (”secondary” meaning it assists the primary cleansing agent which precedes it on the ingredient list). This ingredient can also be used as solubilizing agent for essential oils and fragrance ingredients. Olive oil PEG-7 esters has been deemed safe as used in cosmetics by the Cosmetic Ingredient Review Expert Panel. Their 2014 assessment looked at maximum use concentration ranges for olive oil PEG-7 esters up to 12% for leave-on products and 97% rinse-off formulations.
