olive oil PEG-7 esters
Olive oil PEG-7 esters comes from a process known as transesterification, where pure olive oil is combined with PEG-7, which is 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). This ingredient is considered safe as used in cosmetics.
