The Benefits of Using HEMA & TPO-Free BIAB
When it comes to nail enhancements, BIAB (Builder in a Bottle) has become a game-changer for both nail technicians and beauty lovers at home. Known for its strength, flexibility, and beautiful natural finish, BIAB has transformed how we care for and style our nails. But not all BIABs are created equal.
At Belle Beauty, we’re proud to launch our new HEMA & TPO-free BIAB collection, specially formulated to reduce the risk of irritation while still delivering flawless, long-lasting nails. In this blog, we’ll break down what HEMA and TPO actually are, why avoiding them matters, and the key benefits of choosing a safer, healthier BIAB formula.
What is BIAB?
BIAB (Builder in a Bottle) is a type of builder gel packaged in a convenient bottle with a brush, just like regular gel polish. It’s designed for:
-
Strengthening natural nails
-
Overlaying for added durability
-
Creating a smooth base for colour application
-
Gentle sculpting on short nail extensions
BIAB is loved by nail techs because it’s easier to work with than traditional builder gels, cures quickly under UV/LED lamps, and gives clients a long-lasting manicure with a natural look.
What is HEMA and Why Does it Matter?
HEMA (2-hydroxyethyl methacrylate) is a common ingredient found in many nail products, including gels, acrylics, and polishes. Its main job is to improve adhesion — it helps the product stick to the natural nail.
But here’s the issue:
-
HEMA is one of the leading causes of allergic reactions in nail products.
-
Repeated exposure can cause skin irritation, redness, itching, or swelling around the nails.
-
In more severe cases, users may develop a permanent allergy, making it impossible to wear gel or acrylic products in the future.
For nail professionals, constant contact with HEMA can also pose a risk. That’s why there has been a strong move in the industry toward HEMA-free formulations that are safer for both clients and technicians.
What is TPO and Why Avoid It?
TPO (Trimethylbenzoyl Diphenylphosphine Oxide) is a photoinitiator used in gels and polishes to help them cure (harden) under UV/LED light.
Until recently, many nail brands relied on TPO to achieve smooth curing and long-lasting results. However, due to growing safety concerns, the EU has now officially banned its use in nail products.
👉 From September 1st, 2025, TPO can no longer legally be included in nail products sold within the EU.
This regulatory change reflects increasing evidence that TPO can act as an allergen and potentially cause sensitivity over time. By choosing a TPO-free BIAB, you’re not only protecting yourself and your clients, but you’re also staying fully compliant with EU standards.
Why Choose HEMA & TPO-Free BIAB?
Switching to HEMA & TPO-free BIAB comes with a range of benefits for both nail techs and clients:
1. Reduced Risk of Allergies
