FC-9.9-P
Professional acidic bathroom system
Ingredients
| Kit Component | Key Actives | pH | Purpose |
|---|---|---|---|
| Step 1: Acidic Pre-Clean | Phosphoric acid 8% + SLES 3% + BTA 0.1% | 1.5–2.0 | Heavy limescale, soap scum removal |
| Step 2: Disinfectant Rinse | BAC 0.2% active | 6.0–7.0 | Surface disinfection after acid cleaning |
| Step 3: Protective Coating | Polyquaternium-22 1% + silicone emulsion 2% | 5.0–6.0 | Hydrophobic protective film, shine |
| Step 4: Odor Control | HP--cyclodextrin 3% + encapsulated fragrance 0.5% | 6.0–7.0 | Malodor neutralization, sustained freshness |
Formulation Notes
The professional tier integrates four coordinated products for commercial facilities (hotels, healthcare, institutional settings).
Procedure (Step 1): Dissolve phosphoric acid in water. Add SLES and BTA sequentially. Tint with distinct color (orange) for product identification.
Procedure (Step 2): Dilute BAC 50% concentrate to 0.4% in water (0.2% active). pH adjust to 6.0–7.0 with dilute citric acid or sodium carbonate.
Procedure (Step 3): Prepare polyquaternium-22 solution (2.5% as-supplied in water). Add silicone emulsion (40% active) with moderate shear. Homogenize 10 min.
Procedure (Step 4): Dissolve HP--cyclodextrin powder (or add aqueous solution) in water. Add encapsulated fragrance with low-shear mixing.
The system is designed for sequential use at defined intervals: Step 1 (acidic pre-clean) weekly or as needed for scale buildup; Step 2 (disinfectant rinse) daily; Step 3 (protective coating) weekly after cleaning; Step 4 (odor control) daily or continuous via passive dispenser. The protective coating from Step 3 reduces subsequent soil adhesion by creating a hydrophobic surface with water contact angle >90°, causing water to bead and sheet rather than evaporate and deposit minerals. The odor control in Step 4 functions continuously through slow release of both cyclodextrin (binding incoming malodor molecules) and fragrance from gradually ruptured capsules.
