BPMMA có an toàn cho móng giả không?

A reader who creates press-on nails reached out with an important safety question: “I’ve heard of PMMA being used in nail products, but what is BPMMA, and is it safe to use?”

To answer this question, we consulted our in-house expert in cosmetic ingredients and nail product safety. Here’s what you need to know about BPMMA, its connection to PMMA, and the potential safety concerns when using these materials in press-on nails.

Understanding BPMMA: A Derivative of PMMA in Nail Products

BPMMA likely refers to **Butyl Poly(methyl methacrylate)** or a similar derivative of Poly(methyl methacrylate) (PMMA). PMMA is a common acrylic resin used in many products, including nail enhancements and press-ons. BPMMA would be a modified version of this, where the “B” could stand for butyl or another chemical variation added to adjust its properties, like flexibility or adhesion.

While PMMA is widely used in the beauty industry, safety concerns arise when it’s used improperly (e.g., in unregulated formulations) due to the potential for allergic reactions or skin irritation. BPMMA might be less common, so if it’s a derivative, its safety would depend on its formulation and concentration in the product.

To ensure safety, it’s essential to check with regulatory agencies or product guidelines, like those from the FDA or the EU’s Cosmetics Regulation, which set standards for safe cosmetic ingredients.
