Advanced HOCL Formulation: Balancing Potency, Stability, and Skin Compatibility

The Art and Science of HOCL Formulation

Hypochlorous acid (HOCL) sprays sit at the cutting edge of beauty and hygiene innovation. But creating an HOCL spray that is powerful, stable, and gentle enough for daily use is far more complex than it appears.

Here’s how advanced manufacturers like XJ BEAUTY engineer HOCL sprays to meet these demands.

Potency: Ensuring Efficacy

HOCL is a highly effective antimicrobial—but only when formulated at the right concentration and pH:

• ✔ Concentration (ppm): Lower levels (50–100ppm) for facial sprays; higher levels (200ppm+) for disinfectants.

• ✔ pH Optimization: A pH between 3.8 and 5.5 maximizes antimicrobial power while staying skin-safe.

Stability: Overcoming HOCL’s Fragility

HOCL breaks down rapidly without stabilization. Expert formulators use:

• Electrolysis precision to create active HOCL

• Antioxidant buffers to slow degradation

• Airless, UV-blocking packaging to protect from light and oxygen

Skin Compatibility: Designing for Daily Use

Even at microbe-fighting strength, HOCL sprays must feel gentle:

• Alcohol-free and preservative-free

• Dermatologist-tested for sensitive skin

• Non-disruptive to the skin microbiome
