Do I need to wear protective clothing when using PBTC?

August 7, 2025 admin No Comments

Yes, wearing appropriate protective clothing is recommended when handling PBTC (Phosphonobutane-1,2,4-Tricarboxylic Acid), especially in concentrated forms or during prolonged exposure. While PBTC is generally less corrosive than strong acids, it can still cause mild skin/eye irritation and requires basic safety precautions. Here’s a detailed guide: 1. When to Wear PPE for PBTC Concentrated Solutions (>20% active ingredient). Prolonged or…
