Mascara is another cosmetics, which aims to enhance the eyes by darkening and thickening eyelashes. Going back in time, mascara was first created as early as 4000 B.C. by Egyptians to darken their eyelids and eyelashes. However, the mascara formulations have been significantly changed since then.
The chemistry of mascara can be described as follows. It is formulated as an emulsion cream or solvent suspended liquid or a pressed or moulded cake. The main purpose of such formulation is to obtain a product able not only to wet the eyelashes but also readily spread along them.
The main problem of many ordinary mascaras is their sticky nature, which may cause lashes to cake together. Good mascaras should be able to dry quickly forming a hard-plasticised layer. Hence, it is important to try to maximise the content of wax and water, while minimising the amount of oils, fats and hygroscopic materials in mascaras.
There are different types of mascaras. The first one, emulsified cream mascara, is formulated as oil in water emulsions. The cream is aimed to dry quickly and is usually incorporated into collapsible metal tubes. The second one, liquid mascara, can either be liquid oil in water emulsion or aqueous suspension. Sometimes they also contain a little amount of suspending agent to stabilise the emulsion and retain the colour of pigment. The pigment itself should be inert, which means it has to be unable to combine with other elements present in the formulation.
WUNDEREXTENSIONS Lash Extension & Volumizing Mascara is based on a few main ingredients, which are presented below:
In addition, WUNDEREXTENSIONS introduce the new breakthrough formula, consisting of two separate formulas, which can be combined together to provide multiple lash benefits upon single application. While the ‘Black’ Extension Technology contains the mini tinted 3-Dimensional lash extensions, which would stick to the lashes ensuring a long-term lasting effect due to the presence of wax, the ‘Blue’ Volumizing Technology provides the lash coverage with advanced “micro-hydra-tubes”. Thus, lashes are effectively nourished and protected.
You must have noticed that there are two main types of mascaras: waterproof and non-waterproof. So what is the difference between them?
Mascaras that fall into “non-waterproof” category are hydrophobic, which means they are soluble in water. They usually contain water, glyceryl stearate, ammonium acrylates copolymer, polyvinyl alcohol, and alcohol. Ammonium acrylates copolymer has nitrogen molecules strongly bonded to a hydrogen molecule by hydrogen forces due to their difference in electronegativity. In fact, there are hydrogen bonds present in a water molecule as well. As a result, two compounds would be attracted to each other so that the non-waterproof mascara can be easily removed by water.
“Waterproof” mascaras are defined as hydrophobic and work oppositely to the “non-waterproof” ones. As a rule, they consist of petroleum distillate, polyethylene, carnauba wax, pentaerythrityl hydrogenated rosinate, and tall oil glycerides. The large amount of waxes and oils found in waterproof mascaras demonstrates the nonpolar nature of a compound, and, hence, its inability to dissolve in polar substances e.g. water. Other substances, which should be nonpolar e.g. petroleum distillate oil, are required in order to remove a waterproof mascara from the lashes.
