Eau de cologne is traditionally linked with fresher styles and spray formats, although modern products vary.

Perfume oil describes a carrier and application method, not a universally fixed percentage of aromatic ingredients.

Compare actual formulas, directions and scent experiences before deciding which format suits you.

Compare formats intended for skin, hair and other purposes, and understand why their directions differ. This guide offers general information and does not establish the ingredients, safety or availability of any unfinished XASIS concept. Use the exact finished-product details when buying or applying fragrance.
