Toner Formula Instability After Opening

Asked by: aon.ohn On: April 05, 2016 Product Type: Cosmetics

Question

I have a toner formula with the following composition:

  • Water
  • Vitamin B5
  • Vitamin B3
  • Salicylic Acid EZ (water-soluble)
  • Global Guard preservative

The formula is stable and clear when sealed. However, after opening and using it for a while, it becomes cloudy and develops precipitation/sediment. The staff has tested the sealed formula and found it stable, suggesting the issue is not microbial contamination. What could be the cause of this instability after opening, and how can it be resolved?

Answer

Regarding the issue with your toner formula becoming unstable after opening and use:

You used a formula containing Water, Vitamin B5, Vitamin B3, Salicylic Acid EZ (water-soluble), and Global Guard preservative.

The staff has tested this formula and did not encounter the same instability issue when the product was sealed. They believe the problem is likely not due to microbial contamination, which means increasing the amount of preservative might not resolve the issue.

The staff is continuing to test the formula under different conditions to determine the cause of the instability you are experiencing after opening and use.

Please wait for further updates and recommendations from the staff, as they are actively investigating this specific problem with your formula.
