Lash glue

The primary ingredient in most professional lash glues is Cyanoacrylate (Ethyl, Methyl, or Alkoxy). For sensitive clients, prioritize Alkoxy-cyanoacrylate as it produces lower fumes. Ensure the product is Formaldehyde-free and Latex-free to minimize allergic reactions. Compliance with REACH (EU) or FDA (US) ingredient safety standards is essential for cross-border trade to avoid customs seizures.

Lash glues are highly sensitive to environment. You must select a glue that matches your target market's climate: High-humidity glues (55-65% RH) cure faster, while low-humidity glues (40-50% RH) prevent the adhesive from drying too slowly. Always request the optimal operating temperature range (usually 20-25°C) from the supplier to ensure the glue maintains its viscosity and bonding strength.

Focus on three main metrics: Drying Time, Retention Period, and Fume Level. Professional-grade glues typically offer a 1-2 second drying time for experienced technicians and a retention period of 6-8 weeks. High-quality suppliers on Made-in-China.com provide MSDS (Material Safety Data Sheets) to verify these performance claims and ensure the viscosity is consistent across batches.

Lash glue has a short shelf life (typically 3-6 months unopened and 1 month opened). Ensure the supplier uses specialized nozzle designs to prevent air intake and aluminum foil bags with silica gel desiccant for individual bottle packaging. Check if the supplier provides batch coding and production dates to ensure you are not receiving old stock.

Lash glue is classified as sensitive cargo or dangerous goods (Class 9) in some jurisdictions due to its flammable nature. You must ensure the supplier provides a Report for Safe Transport of Goods and an MSDS. Use temperature-controlled shipping if possible, as extreme heat during transit can cause the glue to polymerize (cure) inside the bottle, rendering the entire shipment useless.

Look for Audited Suppliers who have undergone on-site inspections. Request a sample test from a specific production batch before placing a bulk order. To ensure transaction security, use Secured Trading Services on Made-in-China.com to protect your payment until the goods are verified to meet your specifications.

When negotiating for Private Label (OEM), discuss the Minimum Order Quantity (MOQ) for custom bottles versus custom stickers. Often, a 100-500 unit MOQ is standard for custom labeling. Negotiate for tiered pricing where the unit cost drops by 15-25% as volume increases, and clarify who owns the printing plates for the packaging design.

For the US, ensure the supplier follows Cosmetic Good Manufacturing Practices (ISO 22716). For the EU, the product must be registered on the CPNP (Cosmetic Product Notification Portal) and have a Responsible Person (RP) located within the EU. Failure to provide these documents can lead to permanent bans on your importing license.
