Biphasic it’s a adjective that alludes to what has Two phases (states, values, stages). The concept is often used in the field of electricity to qualify the current that is made up of two alternating currents that are the same and come from the same generator, but are displaced one half-period from each other.
Alternating current is a stream electric whose meaning and magnitude vary according to different cycles. Usually it appeals to the sinusoidal oscillationas it allows the transmission to be more efficient. Typically, electricity reaches homes and businesses through alternating current.
The biphasic systems The 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.
In the field of chemistry, there is talk of biphasic catalysis when two solvents are used that do not mix with each other (they are not miscible), causing the catalytic system to remain contained in one of the phases, while the products and reagents remain in the second. The reaction is generated in the catalytic phase or at the interface, and both phases can be separated by decantation.
It should be noted that biphasic catalysis is applied in processes industrial hydrodesulfurization, hydrogeneration and hydrogenolysis, among others.
It is called biphasic makeup remover to a product of the cosmetic industry that consists of two phases: a watery, which always ranks first, and an oily, which remains on the previous one, since its weight is less. These products are generally capable of removing makeup resistant to weathering. 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 a cosmetic biphasic before using it, since this is how it is achieved that the two phases are emulsified; skipping this step may not achieve the desired results. The most recommended make-up removers of this type have equal parts of both phases, which can be composed of pure rose hydrolate and oils (the best are sweet almond, coconut, sunflower, apricot kernel and olive).
These ingredients are highly sought after by consumers, because they have many beneficial properties, in addition to being very light. In the first place, they do not greasy the skin, but they collaborate with its cleaning and with the closing of the pores; on the other hand, they exercise a action sebum regulating and bactericidal, something that is ideal for treating oily or combination skin.
Biphasic makeup removers can also act positively in the fight against the appearance of wrinkles and the regeneration of the skin. As if this weren’t enough, people with especially sensitive skin greatly appreciate the fact that it helps soothe irritation and reduce redness.
In any case, it is necessary to bear in mind that some biphasic makeup removers can cause adverse reactions on the skin, especially on the eyelids, due to some of its components; for this reason we must make sure that we 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 happens with ingredients such as perfumes and preservatives, which should be avoided by individuals with special sensitivity.
