คำถาม

When combining Niacinamide and Witch Hazel in a formulation, is there a possibility of crystallization occurring, appearing as 'flower-like' crystals? What factors contribute to this?

Niacinamide and Witch Hazel Crystallization

Combining Niacinamide and Witch Hazel does not inherently cause crystallization. Both ingredients are water-soluble.

However, Niacinamide itself can crystallize in a formula, especially under certain conditions:

  • High Concentration: If Niacinamide is used at a high percentage.
  • pH Level: Niacinamide is most stable and soluble within a pH range of 4.0-7.0. While Witch Hazel distillates typically have a pH between 3-5, which is within Niacinamide's acceptable range (3-8), the lower end of this range combined with high Niacinamide concentration could potentially contribute to crystallization.

Therefore, while the combination itself isn't the direct cause, the overall formulation, the concentration of Niacinamide used, and the final pH of the mixture are factors that can lead to Niacinamide crystallization. Ensure Niacinamide is fully dissolved and the final pH is within its optimal range to minimize this risk.

Relevant products include various grades of Niacinamide like Safe-B3™ and Extreme-B3™, and Witch Hazel options such as Witch Hazel (Distillate) and Witch Hazel (Alcohol Free) Plus Allantoin.
