Always Read Lash Adhesive Ingredients & Patch Test New Adhesives.

Check the list of ingredients to verify it contains no ingredients you may be allergic to. If you are allergic to Latex, ensure your adhesive consists of latex-free ingredients. The same advisory precaution applies to adhesives consisting of Formaldehyde.

What Is Cyanoacrylate?

We highly recommend Patch Testing your lash adhesive prior to regular use. Lash adhesives contain Cyanoacrylate. To give you a better understanding of Cyanoacrylate, let’s dive deeper into the technicalities.

Many lash adhesives contain a chemical compound that is composed of a biodegradable Acrylic Resin. Formally identified as Cyanoacrylate, the liquid form monomers are generically known as Super Glue or Krazy Glue. The sticky Cyanoacrylate molecules are easily polymerized, thus they are quickly cured. The Acrylic Resin property sustains tolerance towards repeated heat exposure, bending and cooling.

Cyanoacrylate molecules are used in lash adhesive because its polymerization abilities are unlike traditional water-based adhesives. In the presence of water, humidity and moisture, Cyanoacrylate releases a chemical reaction when curing. The chemical reaction generates strong, long chains of repeating monomers and bonds adjacent surfaces together within seconds of contact. 

Because Cyanoacrylate is an Acrylic monomer, once the liquid compound polymerizes, it transforms to a plastic state. The appearance of cured Cyanoacrylate is a clear result and utilized for industrial, domestic and commercial purposes. Since Cyanoacrylate is impervious to water, its biodegradable feature requires a particular organic solvent to dissolve the adhesive, like Aceton for example. 


Cyanoacrylate Warnings

Cyanoacrylate is a chemical that releases fumes which may cause irritation to your eyes and lungs. Do NOT inhale or ingest lash adhesives as it is extremely unsafe. Do NOT patch test your lash adhesive using generous amounts, rather a tiny drop is feasible for testing purposes. Use caution when applying lash adhesive near your eyes. Avoid getting Cyanoacrylate into your eyes as it may affect your vision. Do NOT apply lash adhesive to your eyelids to prevent gluing your eyes shut accidentally. Avoid overusing lash adhesive, repeated exposure may contribute to flu-like symptoms. When applying lash adhesive, we recommend you are in a ventilated area. 

Cyanoacrylate is flammable, do not expose to excessive levels of heat or fire. Also, excessive application of Cyanoacrylate to your skin is toxic and may result in chemical burns. Avoid heating Cyanoacrylate because it will generate toxic vapors which form explosive air mixtures. Containing no cyanide and non-carcinogenic, Cyanoacrylate is relatively hypoallergenic. However, there is risk of allergies to Cyanoacrylate in rare cases. Irritation from Cyanoacrylate is most common with improper use and handling techniques. Cyanoacrylate may result in adverse reaction to any medication you are taking, proceed carefully.


How To Patch Test For Cyanoacrylate Allergies

Now that we have discussed what Cyanoacrylate is and its warnings, you may proceed with patch testing if you choose. As you have probably discovered by now, lash adhesives is not a one-size-fits-all, as there are various levels to adhesives. We recommend starting with level 1 and 2 adhesives.

To begin patch testing your lash adhesive for allergic reactions to Cyanoacrylate, the application process is simple. You will only need to place a small drop of adhesive 1 in an identifiable spot behind your ear. Next, you will apply a small drop of adhesive 2 within an identifiable distance from adhesive 1. Be sure to keep track of which adhesive is which for test result purposes.

After you have placed the adhesives behind your ear, leave it for 24 hours. Once 24 hours have passed, remove the adhesive and check your results. If you notice reddening around both testing sites, we recommend discontinued use of both adhesives. However, you may proceed at your own discretion and risk if you choose. If you notice reddening around only one of your testing sites, the site that is unaffected would ideally be a safer option for your skin type.
