Tween 20 and Tween 80 are both products belonging to the Tween series, the numbers 20 and 80 refer to the solvent lipophilic or hydrophilic values, the value is small, representing hydrophilic, that is, the emulsified grease is biased towards water, more mild, the larger the value, the more pro-oil. The emulsified grease is oily and has a strong detergency.
Tween 80 and Tween 20 characteristics comparison:
Tween 80, also known as T80, has strong decontamination ability and foam, which is more suitable for viscous oil. Of course, the makeup remover oil made is more suitable for girls who often wear heavy makeup.
Tween 20, also known as T20, its decontamination is slightly weaker, relative to the foam is less than Tween 80, more suitable for lighter oil. Suitable for removing general makeup, most of the daily makeup can be removed. Of course, the advantage of Tween 20 is that it is less irritating, so the best thing for sensitive skin is to use Tween 20 with makeup remover oil.
Tween 80 and Tween 20 are suitable for skin:
The common misconception is that lipophilic Tween is used for dry skin, and hydrophilic Twain is used for oily skin. That is to say, from the purpose of removing makeup, which kind of Twain to use is not based on whether the skin is oily or dry, but depends on the strength of the skin.
If the skin is fragile, use Tween 20, which has good hydrophilicity, because its emulsified oil is milder; if the skin is stronger, use Tween 80 with good lipophilicity.
In general, people with dry skin may have thinner skin, so it is safer to use Tween 20.
In the process of daily use, Tween 80 will cause the layering of the cleansing oil, which needs to be shaken when used, and generally needs to be used in conjunction with the disc series during use, and the effect is the best.
