Eyelash Extension Glue Ingredients: What’s in Our Adhesive?

March 5, 2018 by The Lash Professional. 

It is oh so important to know what’s in the products you use and to feel confident and comfortable using them on your clients! It is also pretty cool to sound like a scientist when you know what each individual ingredient does! Let’s break down eyelash extension glue ingredients and talk about what’s in our adhesive (The Lash Professionals Pro Adhesive)!

Our Professional Lash Adhesive is perfect for both volume and classic lashes. Its 1-2 second bond time provides an instant, almost magnetic hold! But how? Well… Lets take a look at each ingredient to find out!


    Methyl and ethyl are two chemistry terms that you can refer back to as you read. Ethyl and methyl are always attached to another word and merely describe the amount of carbon atoms in a compound:

    • Meth = 1 carbon atom
    • Eth = 2 carbon atoms

    Meth means one, as in there is one carbon atom in a compound beginning with methyl. Eth means two, as in there are two carbon atoms in a compound beginning with ethyl.

    Ethyl Cyanoacrylate in Lash Adhesive

    Now that you know what ethyl means, let’s talk about the big scary word: Cyanoacrylate. It is pronounced SIGH-UH-NO-CRY-LATE. Now that the hardest part is out of the way, we can break down what the heck it means! It actually breaks down into two words: cyanide and acrylate.

    • Cyanide is a carbon atom that has been (triple) bonded to a nitrogen atom. Simple enough, right? Cyanide, alone, can be incredibly dangerous, but it is necessary in this ingredient as a thickening agent. It is important merely for manufacturing purposes but isn’t present at all in the bottled adhesive. Phew!
    • Acrylate is derived from acrylic acid. Acrylic acid is an organic acid that quickly self-polymerizes (hardens or thickens) when exposed to air.

    OMG… What does it all mean? It means acrylate is combined with cyanide to create what we call a cyanoacrylate. It is a quick self-hardening solution. Cyanoacrylates are used in just about any form of quick drying adhesives and are biodegradable. The ingredient in our Pro Adhesive, ethyl cyanoacrylate, has two carbon atoms and is the ingredient that causes the adhesive to bond and hold almost instantly.

    Poly (Methyl Methacrylate) in Lash Adhesive

    This ingredient breaks down into 3 parts:

    • Polymerization
    • Methyl
    • Acrylate

    When you understand those three things, you will be able to easily understand the ingredient. We have touched on all three already, but lets go over them again. To polymerize means to harden. Methyl means one carbon atom. Acrylate is a self-polymerizing (hardening) substance. Put all three together and you have a polymerized version of acrylate containing one carbon atom! Why is this important for adhesive? Because it makes the bond strong! Poly (methyl methacryliate) is another hardening agent used to reinforce and strengthen the ethyl cyanoacrylate. The ethyl cyanoacrylate creates a quick bond, poly (methyl methacrylate) creates a strong bond. Together, it’s an unbreakable bond! (Just kidding, our remover will break it but we can get into that another time!)

    Hydroquinone in Lash Adhesive

    I know, another scary word. Say it with me HIGH-DRO-QUEEEEEEEEEE-KNOWN; Hydroquinone. Hydro can be very simply broken down; it means hydrogen, go figure. Hydroquinone, as a whole however, is pretty difficult to break down in one blog post, so I will do my best by calling it a stabilizer. Its mere purpose in adhesive is to stabilize the polymerization (hardening) of the other ingredients. Without this ingredient, your adhesive would not last! It would quickly harden inside the adhesive bottle.

    Carbon Black in Lash Adhesive

    Yep, the last ingredient. What can it possibly mean? Carbon Black is used not only as a reinforcing agent, but as a pigment! Its name says it all… This ingredient is what gives our adhesive its deep, dark, lash-like color!

    Put all of these components together and The Lash Professionals Pro N1 Eyelash Extension Glue is a quick-bonding, strong-bonding, long-lasting, and WONDERFUL ADHESIVE!

    I hope this will help guide you through your journey of learning all about eyelash extension glue! An entire chemistry class would be necessary to completely understand the ins and outs of eyelash extension glue ingredients. This will, however, give you a general knowledge and break down of what you are using on your clients. Did I mention that our adhesive is also well-priced and artists love it?!
