* Chemical Compatibility: Regular acrylic powders are formulated to react with traditional, strong-smelling monomers (liquids) that contain ethyl methacrylate (EMA). Odorless monomers are typically based on different types of acrylates that require different initiators in the powder for the polymerization (hardening) process to work correctly.
* Curing Issues: If you mix a regular powder with an odorless liquid, the acrylic may not cure properly. It could result in a soft, gummy, or brittle finish. It might also take an excessively long time to harden, or not harden at all.
* Strength and Durability: Even if it appears to harden, the resulting acrylic enhancement will likely be weak and prone to lifting, cracking, or breaking.
* Yellowing: The combination can sometimes cause the acrylic to yellow over time.
* Product Stability: Mixing incompatible ingredients can also compromise the shelf-life or stability of the acrylic nails.
In summary: To achieve the best results, use acrylic powders and liquids that are specifically designed to work together as a system. If you're using an odorless acrylic system, make sure the powder is labeled as "odorless" or "compatible with odorless monomer".
