Bi-phase eye makeup remover

A bi-phase remover is the bottle on the shelf that looks unfinished: a clear layer floating on a watery one, often tinted, that will not mix until it is shaken. The top layer is oil, or light silicones and hydrocarbons that behave like oil; the bottom is water with a little mild cleanser and soothing ingredients. Shaken, the two form a brief, cloudy mixture that soaks into a cotton pad, and within a minute or two the bottle separates again.

The design is a compromise. Waterproof mascara, gel liner and long-wear lipstick resist water and need oil to dissolve them, but a pure oil around the eyes leaves a greasy film. A two-phase remover carries enough oil to shift the makeup and enough water to leave the skin feeling clean. Micellar water, which has no oil phase, struggles with waterproof formulas; a cleansing oil handles the whole face but has to be rinsed off.

Shake the bottle until the layers merge into one cloudy liquid; unshaken, the pad takes up mostly water and the remover does little. Soak a cotton pad, close the eye and hold the pad against the lid and lashes for ten seconds or so, long enough for the oil to loosen mascara and liner. Then wipe down and outward in one stroke rather than scrubbing back and forth. A second pad, folded and pressed under the lower lashes, catches what runs.

On the lips, press a soaked pad on for a few seconds and wipe. The oily phase leaves a light film, and several makers suggest washing or rinsing the face afterwards. Keep the cap closed, and shake the bottle every time you use it: the layers separate again within minutes.

If mascara smears instead of lifting, the pad has usually moved before the oil had time to work. Soak a fresh pad, hold it on the closed eye for longer, twenty seconds rather than ten, and lift it away. A cotton bud dipped in the shaken remover picks out what is left at the roots of the lashes and in the inner corner. Glitter and heavy liner come away more cleanly if the pad is pressed on and lifted straight off rather than wiped across the lid.

Tubing mascaras are the exception. They are made to slide off the lashes in tiny sleeves with warm water and a little pressure, and oil does little to them. Whatever the makeup, resist scrubbing: rubbing tugs at the lashes, and a lash that breaks is simply gone until it grows back.

The balance between the layers varies, and some makers print it. One Korean remover gives its oil-to-water ratio as three to seven, another as two to eight. More oil dissolves heavier makeup and leaves more behind; less oil feels lighter but works more slowly on waterproof mascara. Some bottles are sold for eyes and lips only, others for the whole face, and a few are sold as oil-free, although they separate into two layers all the same. A narrow neck or a dispensing cap wets the pad without a splash; a wide-mouthed bottle tipped over a cotton pad rarely stops at the right moment.

Labels do the rest of the selling. “Ophthalmologist tested”, “hypoallergenic” and “for sensitive eyes” are the makers’ claims. In the United States there is no federal definition of “hypoallergenic” or similar terms, and the Food and Drug Administration says it knows of no studies showing that products sold that way cause fewer reactions than others.^[1] If fragrance troubles your eyes, the ingredient list, not the front of the bottle, will tell you whether a remover contains any.

While makeup was built to come off with cream, cream took it off. Theatrical cold creams were sold to remove greasepaint, and as street makeup spread, cold cream was promoted for powder, rouge and lipstick too, spread on thickly and wiped away.^[2]

Waterproof eye makeup changed the problem. The story goes that Helena Rubinstein launched a waterproof mascara at the New York World’s Fair of 1939, made for the swimmers of the Aquacade. The historian James Bennett calls the story very dubious and thinks the mascara more likely licensed from Vienna, from the woman he takes to be the “Mascara Countess”, Helene Winterstein, with the Aquacade as a publicity stunt. Rubinstein’s advertising in 1940 promised that powder, mascara and lipstick “stays on hour after hour in the water or out”; the claims were later softened to “water-resistant”.^[3] Makeup that sheds water needs oil to take it off, and the long-wear makeup built on silicone resins resists soap and oil-based cleansers alike, according to a 2024 paper in the Journal of Cosmetic Science.^[4] When the two-layer bottle first appeared is harder to say: the record found for this article does not date it.

The words on those bottles have a history of their own. In 1975 the FDA issued a rule that only products shown in human tests to cause fewer reactions than their competitors could be called “hypoallergenic”. Almay and Clinique, both makers of such cosmetics, challenged it, and an appeals court held it invalid.^[5] Both houses sell a remover in the carousel below; the word on the label still means whatever its maker says it does.
