What is HEMA?
HEMA = 2-Hydroxyethyl Methacrylate. It’s used in most gel polishes to improve adhesion, but it’s the #1 allergen in the nail industry
Why HEMA-Free Matters
Repeated exposure to HEMA can cause contact dermatitis, nail plate thinning, and permanent allergies for both clients and nail technicians. Once an allergy develops, it’s permanent.
Catalea HEMA-Free Formula
All Catalea gel polishes are formulated without HEMA. We use alternative monomers that deliver professional adhesion, durability, and 1-coat color payoff without compromising nail health or technician safety.
What is TPO?
TPO = Trimethylbenzoyl Diphenylphosphine Oxide. It’s a photoinitiator used in gel polish to cure under UV/LED lamps.
Why TPO-Free Matters
TPO is classified as toxic to reproduction under EU regulations. Many professional salons now avoid it to protect technician and client safety during daily exposure.
Catalea TPO-Free Formula
All Catalea gels are formulated without TPO. We use safer photoinitiators that cure fast and strong under UV/LED lamps without compromising performance or 21+ day wear.
Professional Safety Standard
HEMA-Free + TPO-Free means safer daily use for nail technicians, healthier nails for clients, and reduced liability for salon owners. Catalea meets the highest EU professional safety standards.
