HOCL Quality Testing: How We Ensure Stability and Safety in Every Batch
Why HOCL Quality Control Is Non-Negotiable
Hypochlorous acid (HOCL) is only as effective as its stability and purity. Poorly produced HOCL sprays degrade into saline within weeks—or worse, grow microbial contaminants that harm users.
At XJ BEAUTY, we’ve built rigorous quality testing protocols to ensure every batch of HOCL spray we produce is safe, stable, and compliant.
Here’s how we do it.
The Challenges of Maintaining HOCL Stability
HOCL is a highly reactive molecule. Its efficacy depends on maintaining:
Precise pH (3.5–5.5) for stability
Consistent active chlorine levels (ppm)
Protection from UV light, oxygen, and contamination
Without strict controls, shelf life drops dramatically.
Our HOCL Quality Testing Process
✅ 1. pH and ORP Monitoring
Every batch is tested for pH and oxidation-reduction potential to ensure HOCL remains active and skin-safe.
✅ 2. Active Chlorine Validation
We measure free chlorine (ppm) to verify antimicrobial potency for both cosmetic and EPA-grade sprays.
✅ 3. Microbial Challenge Testing
Preservative-free HOCL sprays are prone to contamination. We test for bacteria, fungi, and endotoxins under GMP conditions.
✅ 4. Accelerated Stability Testing
We simulate months of storage conditions to confirm product performance over time.
✅ 5. Packaging Compatibility Tests
We verify that bottles prevent UV and oxygen penetration to maintain shelf life.
