Question
How much WS-23 Cooling Agent should be used for a cooling toothpaste formula?
Answer
For cooling toothpaste, use WS-23 Cooling Agent (FEMA 3804) at the catalog toothpaste range of 100-1000ppm (about 0.01-0.10%).
Practical starting point:
| Cooling level | Suggested WS-23 level |
|---|---|
| Mild cooling | 100-200ppm (0.01-0.02%) |
| Medium cooling | 300-600ppm (0.03-0.06%) |
| Strong cooling | 700-1000ppm (0.07-0.10%) |
Recommended trial: start around 100-300ppm (0.01-0.03%), then adjust after taste and cooling evaluation. Do not exceed the catalog toothpaste range of 1000ppm (0.10%) unless you have separate safety and regulatory support for the finished oral-care formula.
Note: this is the toothpaste/oral-care WS-23 catalog item. The cosmetic WS-23 item uses a different cosmetic-use range, so use the FEMA 3804 product data for toothpaste work.
