In plain English

Ethyl Dimethyloctadienoate is a lab-made chemical that smells fruity, often like citrus or berries. It is added to lotions, cleansers, and perfumes just for the scent. It does not moisturize, treat, or protect your skin in any way. If you have sensitive skin or a known fragrance allergy, this ingredient could cause irritation, though for most people it is safe at the tiny amounts used.
