Definition of
biphasic
biphasic it’s a adjective which alludes to what has Two phases (states, values, stages). The concept is often used in the field of electricity to describe the current that is composed of two alternating currents that are equal and come from the same generator, but that are one semi-period displaced from each other.
Alternating current is a current electrical whose direction and magnitude vary according to different cycles. Generally, appeal is made to sinusoidal oscillation, since it allows the transmission to be more efficient. Typically, electricity reaches homes and businesses through alternating current.
The biphasic systems generation and distribution of electricity are based on two alternating currents that are 90° out of phase in their frequency. These systems they are in equilibrium and symmetry when the stresses are added vectorially and their result is zero. In two-phase lines there are two conductors for each phase: that is, four conductors in total.

The concept of biphasic in chemistry
On the ground of the chemistrythere is talk of biphasic catalysis when two solvents that do not mix with each other (are not miscible) are used, causing the catalytic system to remain contained in one of the phases, while the products and reactants remain in the second. The reaction is generated in the catalytic phase or in the interface, and both phases can be separated by decantation.
It should be noted that biphasic catalysis is applied in processes industrial hydrodesulfurization, hydrogenation and hydrogenolysis, among others.

The term in the cosmetics industry
It is called biphasic make-up remover to a product of the cosmetic industry that is made up of two phases: a watery onewhich always comes first, and an oily, which remains above the previous one, since its weight is less. These products are generally capable of removing stubborn makeup. water; this is due to the action of its oily ingredients, which are also ideal for dissolving grease and dirt.
It is very important to shake well cosmetic biphasic before using it, since this is how the two phases emulsify; If we skip this step, we may not get the desired results. The most recommended make-up removers of this type have equal parts of both phaseswhich can be composed of pure rose hydrosol and oils (the best are sweet almond, coconut, sunflower, apricot kernel and olive).

Advantages and disadvantages of biphasic make-up removers
These ingredients are highly sought after by consumers, because they have many beneficial properties, as well as being very light. In the first place, they do not make the skin greasy, but rather help clean it and close the pores; on the other hand, they exert a action Sebum regulator and bactericide, something that is ideal for treating oily or combination skin.
Biphasic make-up removers can also act positively in the fight against the appearance of wrinkles and the regeneration of the skin. fur. As if this were not enough, people with particularly sensitive skin really appreciate the fact that it helps soothe irritation and reduce redness.
In any case, it is necessary to bear in mind that some biphasic make-up removers can cause adverse skin reactions, especially on the eyelids, due to some of their components; for this reason we must make sure to buy the most suitable product for us. For example, if they have soap in the aqueous phase, it is possible that some people will cause irritation in the eyes and skin. Something similar occurs with ingredients such as perfumes and preservatives, which should be avoided by individuals with special sensitivity.
