Product Description
Eyelash extension glue, or adhesive, is a specialized liquid formula primarily made of cyanoacrylate that chemically bonds synthetic lash extensions to natural eyelashes, creating a strong, lightweight, and long-lasting hold. The cyanoacrylate polymerizes and hardens upon contact with moisture in the air, a rapid process that allows lash artists to apply extensions precisely and quickly. Different types of cyanoacrylate and added compounds like thickener, accelerator, or pigment are used to vary characteristics such as drying speed, viscosity, and irritation potential.
Key Components and Function
- Cyanoacrylate: The main ingredient responsible for the quick-drying and strong bond of the glue.
- Polymerization: When exposed to humidity (moisture), cyanoacrylate molecules link together, creating a solid, macromolecule bond.
- Specialized Additives: Other compounds are added to enhance the glue’s properties, such as thickeners, hardening accelerators, stabilizers, and black pigment.
Why Specialized Glue is Necessary
- Strength and Retention: Eyelash extension glue is formulated for a durable hold that keeps extensions in place for weeks, far longer than typical adhesives.
- Rapid Curing: The fast-drying time allows lash artists to precisely apply extensions without the risk of smudging.
- Eye Safety: Professional glues are formulated to be lightweight and minimize irritation to the sensitive eye area.
Types of Cyanoacrylate
Different types of cyanoacrylate exist, each with unique characteristics influencing drying time, viscosity, and sensitivity:
- Ethyl–cyanoacrylate: A common type that dries very quickly with a strong bond but can be irritating for some individuals.
- Alkoxy-cyanoacrylate: A less irritating option, often used in glues designed for people with sensitive eyes.
- Other Types: Other forms like methyl-, butyl-, and octyl-cyanoacrylate offer a range of properties for different applications.
