Allergies and everything you should know about them

The allergy substance is always known HEMA In nail design products.

This type of allergy can also develop after years of product use. HEMA Should not be with Di-HEMA Be confused.
There are 2 substances of different substances that have different benefits in the product. HEMA is needed and the fabric Di-HEMA is produced.

HEMA = 2-Hydroxyethyl Methacrylate or Hydroxyethyl Methacrylate

Di-HEMA = Di-HEMA trimethylhexyl dicarbamate

Both substances are monomers used for the polymerization of UV gels.

The Polymerisation Is a chemical reaction in which monomers, mostly unsaturated organic compounds, under the influence of catalysts and by dissolving the multiple bond to form polymers (molecules with long chains consisting of interconnected monomers) React. (Source: Chemie.de )

However, the molecular size of Di-HEMA is much larger than that of HEMA and therefore can Di-HEMA not so easily absorbed into the skin , Like HEMA.*

According to the British Association of Dermatologists (BOD) and all other published scientific articles is HEMA the allergen product No. 1 for nail design products . *

As proof of this, the published European Scientific Committee for Consumer Safety (SCCS) In 2018 a report stating that there is no scientific evidence that Di-HEMA causes allergies !

ATTENTION-Cross allergy-HPMA

Hydroxypropyl methacrylate ( 2-HPMA ), Which is also known as hydroxypropyl methacrylate ( HPMA ) Is referred to, by the way, this is 2t-most common nail product allergen According to BOD. This is used by some manufacturers as an alternative to HEMA and in HEMA-free acrylic liquid. Subsequently, those who switched to HEMA-free monomer because they already had an allergy to HEMA could often also develop HPMA allergy. *

* Please note that this is not a medical recommendation, because I am not a doctor. You may also not develop an allergy or cross-allergy.

What is Scientific Committe for Consumer Safety (SCCS) ?

SCCS is a Consumer Safety Scientific Committee. It is a panel of dermatologists, toxicologists and EU scientists who decide which ingredients can be used for cosmetic purposes, in which region of the human body and whether the amount of ingredient should be limited for a given application.

In 2018, the SCCS published a report on the safety of HEMA and Di-HEMA And shows that these substances are different.
