Is it safe to use eyelash extension glue with Cyanoacrylate?

Introduction to Cyanoacrylate use in cosmetics

Cyanoacrylate is a fast-drying, powerful adhesive widely used in professional eyelash extension glues. Its ability to create strong, long-lasting bonds makes it an essential component in the lash industry.

Cyanoacrylate history: from World War II to modern cosmetic use

Cyanoacrylate was accidentally discovered in 1942 by American chemist Harry Coover at Eastman Kodak, while developing clear plastics for rifle sights during World War II. Due to its extreme stickiness, it was initially dismissed for military use.

Years later, Coover revisited the compound and, in 1958, launched Eastman 910, the first commercial product, later known as "Super Glue" thanks to its impressive bonding capabilities.

During the Vietnam War, military medics used Cyanoacrylate sprays to close battlefield wounds quickly and stop bleeding. Although not FDA-approved at the time due to potential skin irritation, it proved life-saving in emergency settings.

This led to the development of derivatives like 2-octyl cyanoacrylate, which was FDA-approved in 1998 for civilian medical use under brand names like Dermabond. Its journey from accidental discovery to medical and cosmetic applications is a testament to its versatility and importance.

What exactly is Cyanoacrylate?

Cyanoacrylate is a reactive adhesive that polymerizes rapidly in the presence of moisture. It is ideal for bonding non-porous surfaces like artificial eyelashes to natural lashes, offering secure and long-lasting adhesion.

Common types of Cyanoacrylate used in lash adhesives

• Ethyl Cyanoacrylate (CAS #7085-85-0) – The most widely used in lash glues due to its balance of fast drying and strong bonding. [1]
• Ethoxyethyl Cyanoacrylate (CAS #21982-43-4) – Known for lower fume emissions, suitable for sensitive eyes. [2]
• Polymethyl Methacrylate (CAS #9011-14-7) – A film-forming agent often added for texture, not an adhesive itself. [3]

European regulations on Cyanoacrylate

According to the COSING database of the European Commission, Cyanoacrylate is permitted in cosmetic use without special restrictions when used within accepted concentrations. [4]

Approval by health authorities

The Spanish Medicines and Medical Devices Agency (AEMPS) includes Cyanoacrylates in its inventory of authorized cosmetic ingredients. The World Health Organization (WHO) has also acknowledged the compound’s utility in medical adhesives. [5], [6]

Can Cyanoacrylate cause allergies or reactions?

Cyanoacrylate can cause irritation or allergic responses in sensitive individuals. Some glues are formulated as “low fume”, emitting fewer vapours. However, these products have a slower drying time (5–7 seconds) and are generally unsuitable for advanced lash techniques like Russian Volume, where quick setting is crucial to maintain fan shape.

What to do in case of accidental contact?

• Inhalation: Move to fresh air. Seek medical attention if discomfort continues.
• Skin: Soak in warm soapy water and gently separate. Never pull apart.
• Eyes: Rinse thoroughly with water and go to the emergency room.
• Ingestion: Do not induce vomiting. Let saliva work to detach adhesive. Contact medical services.

Essential safety precautions when working with Cyanoacrylate

• Work in well-ventilated spaces or use fume extractors.
• Wear nitrile or PVC gloves (avoid latex).
• Do not apply directly to skin or mucous membranes.
• Store sealed and away from heat or sunlight.

Are there safer alternatives?

Some companies offer Cyanoacrylate-free or hypoallergenic adhesives. However, these typically have weaker bonding and slower drying times. No alternative currently matches the performance of properly used Cyanoacrylate in professional settings.

Conclusion

When used professionally and under regulated conditions, Cyanoacrylate remains one of the safest and most effective options for eyelash extension adhesives. Its development from a WWII-era discovery to a cosmetic staple illustrates its reliability and scientific backing.
