Processing Methods & Reference Formulations
A. Cosmetic cream
Add BZK during the cool-down phase to prevent degradation. Use compatible emulsifiers to avoid destabilization. Typical concentration is 0.1–0.2%, and ensure the preservative system complements BZK’s antimicrobial spectrum.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Water (Aqua) | 70% |
| Glycerin | 5% |
| Cetearyl Alcohol | 4% |
| Caprylic/Capric Triglyceride | 6% |
| Isopropyl Myristate | 3% |
| Stearic Acid | 2% |
| Triethanolamine (TEA) | 0.8% |
| Benzalkonium Chloride (50% sol.) | 0.2% |
| Allantoin | 0.5% |
| Panthenol (Pro-Vitamin B5) | 1% |
| Tocopheryl Acetate (Vitamin E) | 0.5% |
| Dimethicone | 2% |
| Fragrance | 0.5% |
| Phenoxyethanol & Ethylhexylglycerin | 1% |
| Citric Acid (10% solution) | 0.4% |
B. Cosmetic cleansers
For cosmetic cleansers, add Benzalkonium Chloride during the final formulation stage at temperatures below 40°C to preserve its antimicrobial activity.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Emollients | 20-30% |
| Preservatives (BKC) | 0.01 to 0.1% |
| Humectants | ~0.8% |
| Water | 70-80% |
| Fragrance, pH Adjusters, Surfactants etc. |
C. Shampoo
When adding Benzalkonium Chloride (BKC) to shampoo, incorporate it during the cool-down phase to maintain its antimicrobial efficacy.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Benzalkonium chloride | 0.5% |
| Aqua | 96.85% |
| Lauryl Methyl Gluceth-10 Hydroxypropyldimonium Chloride | 0.2% |
| Glycerin, Rosa Canina Fruit Extract | 1% |
| Hexylene Glycol | 0.8% |
| Sodium Chloride | 0.5% |
D. Hand Wash
When formulating hand wash with Benzalkonium chloride, ensure it is added during the cooling phase to prevent degradation.
| Key Ingredients | Indicative Dosage (% w/w) |
|---|---|
| Benzalkonium chloride | 0.13% |
| Cocamidopropyl Betaine | 1.4% |
| Water | 85-95% |
