Contrary to popular speculation, the use of cosmetics is not a modern phenomenon. Although we can not say for sure if our obsession with beauty began the human is the fact that it has been around for a very long time. In other words, back to the first archaeological evidence of cosmetics usage on the way to Egypt around 3500 BC, was recorded. This shows that there are cosmetics for thousands of years. It is said that ancient Egyptian women used to darken the eyelids actually carbon.
With more people involved in its present form, it is not surprising, is perfume, cosmetics and skin care products a multibillion-dollar industry that confuses its customers a wide range of products to choose from. Unlike before, where the lack of regulations on the manufacture of cosmetics to extreme side effects such as malformations or has even led to death, are now the governing bodies that establish guidelines for the manufacture of cosmetics. The rules for these agencies, the companies that manufacture or sell cosmetics is responsible for any side effects that may occur as a result of the use of this product are.
To prevent cases of civil liability, cosmetic companies have dug deeper into the science in order to save their businesses. Using the technology to make cosmetics safer in a position, by making specific ingredients in their products, skin can be beautiful. Here are some examples:
In short, dispersed emulsifiers, emulsifiers oil droplets in water or water droplets dispersed in the oil. In any case, the droplets, which determines dispersed to the surface tension of water and oil phases thereby to change the separation. The result is often a product that is not only a uniform texture of the skin, but also safer. Emulsifiers also by reducing transepidermal water loss, which act sometimes cause itching. Allergic reactions to certain cosmetic oils are also reduced through the use of emulsifiers.
Preservatives, preservatives for the sole purpose of prevention to compensate for the growth of microorganisms. Conservatives such as benzyl alcohol have been known to kill bacteria and fungi, the cosmetics that ultimately harms degrade the user. The removal of mercury-based preservative thimerosal, for example, also be carried out after it has been shown to be highly toxic to the nervous and immune systems.
PH stabilizers – Introduction of stabilizing the pH had to face the unwanted side effects such as skin allergies, a skin rash caused when the product was applied to fight. The work of these stabilizers is to prevent excessive acidity or alkalinity on this issue. Creation on the fact that most cosmetic ingredients readily soluble in water and thus were based, had special solvent to be developed for such ingredients as a solution, if the need arose.
The important thing to remember is that if science is to reduce the harmful effects of cosmetics, it is certainly more convenient to consider that chemical compounds have become very complex and gain a deeper understanding of the ingredients used are very useful in the long run , is especially if the skin is affected.
