Compatibility of PoreNin™ with Chitox-3000, ActiveProtec™, and Vitamin B6 in Toner

Combining PoreNin™ (Natural Extracted Tannic Acid) with the ingredients you mentioned requires careful consideration of chemical interactions and solubility limits. Here is the breakdown of the compatibility:

1. PoreNin™ + Chitox-3000 (Chitosan Oligosaccharide)

• Compatibility: Likely Incompatible (Cloudiness/Precipitation).
• Rationale: Although you noted that Chitox-3000 is a "sugar" (oligosaccharide), its INCI is Chitosan. Chitosan is a cationic (positively charged) polymer. PoreNin™ (Tannic Acid) is a polyphenol that acts as a powerful anionic (negatively charged) cross-linker.
• Result: When combined in a water-based formula like a toner, these two ingredients typically react to form a "polyelectrolyte complex," which results in immediate cloudiness or the formation of sediment/precipitation. This is similar to how tannic acid reacts with proteins.

2. PoreNin™ + ActiveProtec™ UV & ActiveProtec™ OX

• Compatibility: Risk of Cloudiness and pH Conflict.
• ActiveProtec™ UV: This is a micellar system. Tannic acid, being a strong polyphenol, can sometimes disrupt micellar structures or interact with the surfactants used to solubilize the UV filters, potentially leading to cloudiness.
• ActiveProtec™ OX: This product contains stabilizers like Sodium Metabisulfite and chelators. It is an electrolyte. Tannic acid is sensitive to high electrolyte concentrations, which can reduce its solubility.
• pH Conflict: ActiveProtec™ OX requires the formula pH to be above 4.0 to remain stable. However, if you include Vitamin B6, it will naturally pull the pH down to 2.0–3.0, which would cause ActiveProtec™ OX to become unstable.

3. 3% PoreNin™ + 2% Vitamin B6 (Clear Toner?)

• Compatibility: High Risk of Precipitation/Cloudiness.
• Solubility Limit: The maximum recommended usage for PoreNin™ is 3.0%. At this concentration, it is at its limit of solubility in water.
• Electrolyte Effect: Vitamin B6 (Pyridoxine Hydrochloride) is an electrolyte. Adding a high concentration (2%) of an electrolyte to a solution already saturated with Tannic Acid often triggers a "salting-out" effect, causing the Tannic Acid to precipitate or the solution to turn cloudy.
• Recommendation: To maintain a clear toner, it is recommended to reduce the concentration of PoreNin™ (e.g., to 1-1.5%) if using it alongside other high-concentration actives or electrolytes like Vitamin B6.

Summary Table

Suggested Action: If you desire a clear toner, avoid combining PoreNin™ with Chitox-3000. If using Vitamin B6, ensure you test the solubility at lower percentages of PoreNin™ first, and check the final pH to ensure compatibility with your preservative and stabilizer systems.
