I am Harold, the founder of CHROMÉCLAIR. Three years ago, when I mixed the first bottle of nail polish gel in a small nail salon in Guangzhou, I never imagined that I would one day be at the forefront of industry transformation. However, the EU’s ban on TPO and HEMA served as a wake-up call—true beauty should never come at the expense of health. Today, I would like to share the details of this 678-day formulation revolution.
A Stinging Sense of Responsibility
When the European Commission issued Regulation (EU) 2023/1545, my inbox was flooded with panic-stricken messages:
‘Is HEMA to blame for my nails peeling and bleeding after each removal?’
‘Is TPO really capable of penetrating the nail bed, making it unsafe during pregnancy?’
Laboratory data was alarming: traditional TPO photoinitiators release formaldehyde migration levels three times above the safety threshold during curing, and HEMA monomers are the primary cause of 90% of contact dermatitis cases. More critically, these substances accumulate through repeated exposure at the fingertips of nail technicians—many of whom have already developed nail atrophy!
The path to breakthrough: 137 failed iterations
Phase 1: Searching for TPO alternatives
Traditional photoinitiators are a double-edged sword: removing TPO means a drastic drop in curing efficiency. We tested 32 materials, including 184 and 907:
√ 184 photoinitiator has a 40% slower curing speed
√ 907 photoinitiator leaves a pungent residual odour
√ ITX may cause photosensitivity
The turning point came with Dr. Schmidt’s patent for natural extracts. The photosensitive polysaccharide complexes extracted from seaweed produce remarkable effects at specific wavelengths:
▶ Curing speed increased to 5 seconds (traditional formulas require 9 seconds)
▶ LC-MS testing shows zero volatile organic compound emissions
▶ Migration tests indicate safety exceeds EU standards by 92%
Phase 2: The HEMA monomer replacement challenge
Removing HEMA was like removing the ‘scaffolding’ of the formula, causing a complete collapse in flowability and adhesion. When the engineer presented the 43rd batch of clumped samples, I wrote on the lab whiteboard:
‘We will never compromise on performance, nor will we compromise on safety!’
The breakthrough came from medical-grade dental resin materials—hyperbranched acrylic acid ester dendritic polymers:
✅ Molecular weight increased by 300%, unable to penetrate the nail bed
✅ Hydrogen bond self-assembly technology achieves silk-like flowability
✅ Passed the OECD 439 skin irritation test (0.3 points out of 4)
Real-world proof: When sensitive skin meets safe adhesive
We invited 50 severely allergic nail technicians to participate in a blind test:
Test item Traditional UV gel Safe Renewal Gel
Redness rate after 24 hours 68% 3%
Nail bed peeling cases 17 cases 0 cases
Pungent odour during application 4.2 points 0.5 points
Parisian nail technician Sophie’s feedback moved me: “When doing crystal extensions for clients, my right index finger always had a band-aid on it. After using your new gel for two weeks, I removed the last bandage—a wound that had been festering for ten years had healed!”
Performance Peak: Safety and Beauty in Harmony
At the Milan Nail Championship, the judges were surprised to discover:
✨ Mirror-like self-levelling: Self-levelling angle reduced to 8° (industry standard 15°)
✨ Ultimate durability: no scratches after 500 steel wool abrasions
✨ Colour accuracy: RGB colour difference ΔE < 0.8 (indistinguishable to the naked eye)
What excites salon owners even more:
- 15% less adhesive per bottle (precise flow minimises waste)
- 230% increase in repurchase rate for allergy-prone customers
- UV lamp power requirement reduced to 24W (40% energy savings)
Transparent commitment: safety you can see

Dr. Laura’s Review:
‘Traditional formulas are like applying preservatives to nails, while Harold’s breakthrough lies in using biocompatible materials to create a protective barrier—like wrapping nails in a smart breathable membrane.’
This is not just a formula upgrade; it is a awakening of industry conscience.
When my daughter first used the Safe Gel to apply ‘Galaxy Purple’ for me, the twinkling stars on her fingertips showed me what nail art should truly be: fearless creativity, safe and vibrant.
