In plain English

Allyl Trimethylhexanoate is a man-made chemical that smells fruity and floral. It's added to products like lotions and perfumes just for the scent. It doesn't moisturize, treat, or improve your skin in any way. Because it's a fragrance ingredient, it could potentially cause irritation for people with very sensitive skin, but it's generally considered safe at the tiny amounts used in cosmetics.
