- Haircare: Perfect for preserving shampoos, conditioners, and other water-containing haircare products.
- Anhydrous Products: Can be used in non-water-based formulations, such as balms and butters, though its efficacy is less optimal in fully anhydrous systems.
- Emulsions: Works well in oil-in-water (O/W) and water-in-oil (W/O) emulsions to maintain stability.
Usage Instructions
- Recommended Use: 0.5% to 1.5% of the total weight of the formulation.
- Temperature Considerations: Add Optiphen during the cool-down phase, ideally when the formulation is below 60°C (140°F), to prevent destabilization or degradation of the preservative.
- pH Compatibility: Best used in products with a pH between 4.0 and 8.0.
- Formulation Tip: Optiphen can be prone to destabilizing emulsions if added at too high a temperature. It’s recommended to mix thoroughly as the product cools to maintain formulation integrity.
