What is in my Lash Glue?

Eyelash glue plays such a vital role to lashing, it is our trunk to our tree, our apple to our pie, as let’s be honest where would we be without it?  The lash game is high & nowadays the more knowledge you have, the more that you learn that there is much more to just sticking the lash on a lash… In fact, where does it stop?  So do you have all the info to pass an exam on lash glue?  If not here are some detailed informative facts about lash glue, that I have learnt from my 15 years lashing & 7 years supplying lash products.  This information is also great if you ever have a client who requires to know more information about eyelash glue & it’s properties.



First thing’s first as we have probably all heard of this one.. Formaldehyde is a by-product that occurs during the production process of other components coming together.  All lash adhesives contain formaldehyde, a completely formaldehyde lash adhesive does not exist, as it is impossible to mix the important components together without the creation of it!

It is more importantly how much of it is in our eyelash glues that we need to worry about, at BBgroup we offer lash adhesives with the lowest possible measures, exposure to such small amounts is not harmful to health.  Formaldehyde becomes toxic to humans when inhaled in large quantities over long periods of time, which is not possible when regularly working, however we do always recommend that you work in a well ventilated environment & wear the correct PPE to avoid inhalation.


Cyanoacrylate is a base ingredient used in lash glue to hold the lash in place for several weeks & also allows the adhesive to dry in seconds.  This is also the component that gives adhesive the fume & odour.  There are 5 different types of cyanoacrylate, Ethyl cyanoacrylate is the most commonly used for it’s fast drying time.  All lash adessives contain cyanoacrylate, for sensitive lash clients look for an adhesive that contains a softer cyanoacrylate such as Alkoxy-2.  BBGroup do not currently offer a sensitive adhesive due to slower setting times & reduced retention & after thorough research into lash adhesive allergies it is extremely evident that sensitive adhesive have no better effect than a regular adhesive. 

Methyl Methacrylate

Methyl Methacrylate or also known as PMMA is the component that works with cyanoacrylate to ensure a long-lasting bond to the natural lash.  It is the strong hold that ensures several weeks of retention, ensuring the lashes stay in place for a long time.


Hydroquinone is present in a small amount to ensure the glue stays liquid in the storage bottle.

Carbon Black

As the name suggests, this is the component that adds depth & the black colour to the adhesive.  Lash clients who have a carbon allergy could be offered a translucent adhesive where carbon is not present.


Latex is a natural rubber that adds excellent viscosity & durability to lash glue, the reason we do like to avoid latex in adhesive is simply to avoid the higher risk of allergy, as latex is a commonly known component that can cause reactions.  Generally, clients will know if they have a latex allergy, therefor it I advised to ask during consultation.  Here at BBGroup we offer both latex free & latex adhesives.

In summary

The key components discussed here can vary from brand to brand.  It is important to do your research & choose a lash glue that is right for you & your clients, avoid cheaper adhesives, if they seem to good to be true, generally they are & will more than likely contain higher contents of ingredients that are expected to give your clients a reaction.
