Nail glue is primarily made of cyanoacrylate, often in combination with other ingredients to improve its properties.
Here's a breakdown of common components:
-
Cyanoacrylate: This is the main adhesive component. Different types of cyanoacrylate may be used, such as:
- Beta-methoxyethyl cyanoacrylate
- Ethyl cyanoacrylate (most common)
- Octyl cyanoacrylate
-
Polymethyl Methacrylate (PMMA): This polymer is sometimes added to enhance the glue's strength and durability.
-
Other Additives: Manufacturers may include other ingredients for various reasons, such as:
- Plasticizers: To increase flexibility and prevent brittleness.
- Stabilizers: To extend shelf life and prevent premature hardening.
- Thickeners: To control viscosity and application.
- Odor Masking Agents: To reduce the strong odor of cyanoacrylate.
In summary, nail glue formulations vary but generally contain cyanoacrylate as the active ingredient, often in combination with PMMA and other additives to enhance specific characteristics like flexibility, strength, and odor.
