Many lash glues contain hidden toxins like PMMA and Hydroquinone—both linked to serious health risks. This is bad news for artists and clients alike. But there’s a safer solution. In this guide, I’ll explain what PMMA-free & Hydroquinone-free glue is—and why switching is crucial.
PMMA-free and Hydroquinone-free eyelash extension glue is a type of adhesive that excludes two high-risk chemicals—Polymethyl Methacrylate (PMMA) and Hydroquinone—both of which are classified as potential carcinogens. These glues are safer for both lash technicians and clients, especially those with sensitive skin or allergies. They offer strong retention, fast drying time, and are often compliant with strict international safety regulations.
Let’s dive deeper into what makes traditional glues harmful—and why going chemical-free is the smarter, safer choice.
What is PMMA in lash glue?
PMMA, or Polymethyl Methacrylate, is a synthetic plastic added to many lash glues to reinforce the bond between the natural lash and the extension. While it does help with retention, PMMA is classified as a Class III carcinogen in several countries. Continuous exposure can lead to respiratory issues, eye irritation, and in worst cases, contribute to cancer development. As awareness grows, PMMA-free glues are becoming the preferred choice among health-conscious beauty professionals.
Why is hydroquinone used in lash glue—and what’s the risk?
Hydroquinone is used as a stabilizer to prevent the glue from curing prematurely inside the bottle. However, this chemical is known for its potential health risks. It’s commonly banned or restricted in countries like South Korea, Canada, and California due to its toxic and carcinogenic properties. For lash technicians and clients exposed regularly, using Hydroquinone-free lash glue is not just safer—it’s essential.
What eyelash glue can I use if I’m allergic to lash glue?
If you or your clients have experienced redness, irritation, or itching after a lash appointment, your current glue may be the culprit. Sensitive lash glues contain reduced levels of common irritants like cyanoacrylate, and completely exclude PMMA and Hydroquinone. Glues like Cosey Lashes’ NC05 and NC06 are ideal—they’re designed specifically for sensitive eyes and still deliver professional-level performance.
What are the safest eyelash extension glues?
The safest lash adhesives are those free from PMMA, Hydroquinone, formaldehyde, and excess ethyl cyanoacrylate. Brands like NovaLash have led the way with formaldehyde-free products. However, Cosey Lashes offers a high-performance, health-conscious option with their PMMA-Free & Hydroquinone-Free NC Series—combining safety with salon-grade effectiveness.
What are the key eyelash glue ingredients to avoid?
Here’s a quick list of eyelash glue ingredients to avoid:
- Polymethyl Methacrylate (PMMA) – Increases cancer risk and respiratory irritation.
- Hydroquinone – A banned stabilizer in many countries.
- Formaldehyde – Can be formed as a byproduct and causes allergic reactions.
What’s the difference between NC05 and NC06 glue?
| Feature | NC05 Glue | NC06 Glue |
|---|---|---|
| Drying Time | 0.5 seconds | 1 second |
| Retention Time | 6–7 weeks | 6–7 weeks |
| Viscosity | 100–110 cps | 130–140 cps |
| Ideal Humidity/Temp | 40–65% / 20–27℃ | 40–65% / 20–27℃ |
| PMMA & Hydroquinone Free | ✅ | ✅ |
Both options are high-performing, but NC05 is ideal for advanced lash artists who work quickly, while NC06 is great for beginners or warmer climates.
Can I private label PMMA-free lash glue?
Absolutely! At Cosey Lashes, we offer private label PMMA-free & Hydroquinone-free glues to lash brands, salons, and resellers. Whether you’re launching your own brand or upgrading your product line, we provide wholesale and customized packaging solutions tailored to your needs.
What laws regulate eyelash extension glue ingredients?
Countries like South Korea, Canada, and California (USA) have implemented strict bans or limitations on the use of PMMA and Hydroquinone in cosmetic products. These regulations are based on evidence linking these substances to serious health risks. Using compliant glue not only protects your clients—it also keeps your business safe from legal issues.
Summary
Safer lash glue isn’t just a trend—it’s a necessity. By choosing PMMA- and Hydroquinone-free adhesives like NC05 and NC06, you protect your clients, your artistry, and your health. Got questions or want private label options? Let’s connect!
