Jel ojede fotobaşlatıcı 184 (CAS 947-19-3) ile fotobaşlatıcı TMO (CAS 270586-78-2, non-TPO) arasındaki fark nedir?
| Characteristic Dimensions | CHLUMINIT® 184 (CAS 947-19-3) | CHLUMINIT® TMO (CAS 270586-78-2) |
| Chemical Type | α-Hydroxyketone | Acetyl Oxyphosphine (Methyl Oxy Substituted) |
| Absorption Wavelength Profile | Short-wave absorption type. Primary peaks at ~245nm and ~280nm, with weak absorption of LED light above 365nm. | Long-wave, high-efficiency absorber. Peak absorption typically ranges from 380-400nm, offering exceptional compatibility with modern LED nail lamps (365-405nm) and superior absorption intensity compared to TPO. |
| Core Curing Capability | Surface/shallow-layer curing specialist. Rapid surface curing under suitable light sources. | Deep/penetration curing specialist. Its strong absorption of long-wave light enables penetration through highly pigmented color gels and thicker layers, achieving thorough curing of underlying layers. |
| Yellowing Properties | Extremely low yellowing. Essential initiator for producing colorless, transparent, light-colored, and white gel polishes to ensure pure color. | Significant yellowing. Its photolysis products cause noticeable yellowing in the system, making it absolutely unsuitable for white, light skin-tone, transparent, or any products demanding high color purity. |
| Light Source Compatibility | Requires light sources containing sufficient short-wave UV. Poor compatibility with certain narrow-spectrum LEDs, prone to incomplete curing. | Nearly perfectly matched with modern mainstream LED nail lamps, delivering exceptional curing efficiency. Serves as the core initiator in “LED-curable formulations.” |
| Function in Formulation | Provides rapid surface curing while preventing color yellowing. | Provides powerful deep-penetrating curing capability, solving curing challenges for colored gels and thick layers. |
| Storage Stability | Relatively stable under indoor light; excellent thermal stability. | Extremely sensitive to visible light. Must be stored strictly away from light (use dark/amber bottles) to prevent rapid decomposition and degradation. |
Specific Effects on Gel Polish Formulations and Selection Strategies
Impact on Curing Effectiveness
Using Only TMO: May result in incomplete curing of dark, high-coverage color gels (e.g., black, red, royal blue), manifesting as tackiness, surface wrinkling, poor durability, and easy peeling. However, it cures transparent and light-colored gels well without discoloration.
Using TMO Only: Ensures complete curing for all colors (including dark shades) and thick layers (UV gel polish). However, it causes severe yellowing in light-colored polishes (white turns beige, nude pink turns dirty orange) and shortens formulation shelf life, requiring strict light-blocking packaging.
Best Practice: Blended Use
In professional gel polish formulations, blending 184 with TMO (or TPO) is the standard approach to balance performance and aesthetics:
Role of 184: Provides rapid surface initiation and resists yellowing.
Role of TMO: Delivers deep penetration for complete curing.
Blending Ratios:
Clear gels, top coats, light/white gels: High 184 ratio (e.g., >90%), with minimal TMO (<10%) added for curing assistance. Strict yellowing testing required.
Dark/solid color gels: Reduce 184 ratio and significantly increase TMO ratio (e.g., 30% : 70%). Yellowing is masked by dark pigments; thorough curing is the primary requirement.
Universal color gels: Use a balanced ratio (e.g., 50% : 50%) and adjust based on actual testing.
Conclusion and Direct Recommendations
They are not substitutes but complementary agents. TMO cannot simply replace 184 entirely, nor vice versa.
Selection Criteria:
If your goal is to formulate non-yellowing clear gels or ultra-pure white gels, 184 is your primary initiator.
If your goal is to ensure 100% cure of deep red, black gels, or 3D thick layers under LED light, TMO is your primary initiator.
For the vast majority of colored nail gels, both must be used in combination. By adjusting the ratio, find the optimal balance between “color preservation” and “cure assurance.”
Special Note: When using TMO, production, storage, and packaging must be strictly light-protected throughout the entire process. Otherwise, the product will prematurely degrade and become ineffective in the bottle.
In short, 184 safeguards the gel polish’s “appearance” and color authenticity, while TMO safeguards its “inner qualities”—complete curing and durability. A successful formula requires both to work in tandem.
