Everything about the cosmetic composition of a two-phase makeup remover.

The biphasic lotions are cosmetic products used for removing makeup from the skin. They are highly valued because they are particularly effective at removing water-resistant or long-lasting makeup. Biphasic makeup removers combine the benefits of both micellar waters and makeup removing oils.

sensitive skin, as they are very gentle.

The effectiveness of biphasic makeup removers stems from the fact that they are composed of two separate phases, an aqueous phase and an oily phase, each containing specific ingredients.

• In the aqueous phase.

  Denser than the oil phase, the aqueous phase forms the lower phase of a biphasic lotion. It is typically based onhydrosol. Less concentrated than essential oils, hydrosols are gentle ingredients that are very well tolerated by the skin. Among the most commonly used hydrosols to formulate a biphasic makeup remover, we find those of orange blossom (INCI: Citrus Aurantium Dulcis Flower Water), Damask rose (INCI: Rosa Damascena Flower Water), lavender (INCI: Lavandula Angustifolia Flower Water) and cornflower (INCI: Centaurea Cyanus Flower Water).

  This can be supplemented with actives such as vitamins, amino acids, or minerals. They provide an additional property to the makeup remover, making it more hydrating or soothing. Finally, it is in this phase that we find the preservatives, important molecules in a cosmetic product, as they help prevent microbial contamination and extend the product's shelf life. Preservatives are preferably added in the aqueous phase, as water is a naturally more conducive environment for the growth of fungi, bacteria, mold...

• In the oily phase.

  The majority of the oily phase is made up ofvegetable oils, which are rich in fatty acids. Vegetable oils have beneficial properties for this type of care because their texture allows them to gently remove makeup without damaging the skin.

  Biphasic makeup removers often contain several different vegetable oils, such as those of jojoba (INCI: Simmondsia Chinensis Seed Oil), ofsweet almond (INCI: Prunus Amygdalus Dulcis Oil), of apricot kernels (INCI: Prunus Armeniaca Kernel Oil) or ofavocado (INCI: Persea Gratissima Oil).

  These vegetable oils have skin-softening properties and serve as natural thickeners. To enhance their effect, silicones or other emollients are sometimes added to the oil phase of biphasic makeup removers, such as isopropyl myristate or caprylic/capric triglyceride.
