Oral care demands cooling that reads as clean and active – menthol character plus WS-agent endurance combine for toothpaste and mouthwash applications.
Key Highlights
- Menthol 0.1-0.5% provides classic clean-mint character
- WS-23 0.2-0.8% extends cooling endurance through brushing
- Cooling must survive surfactant and fluoride matrices
Two-Agent Strategy
Menthol delivers the recognizable mint-clean opening; WS-23 extends cooling sensation well past the rinse or brush. The combination outperforms menthol alone in consumer cooling-duration testing.
Matrix Considerations
- Toothpaste: high-abrasive, surfactant matrices demand robust integration
- Mouthwash: aqueous-ethanol systems, rapid flavor release profile
- Both: fluoride and active ingredients interact with flavor perception
Frequently Asked Questions
How much menthol in toothpaste?
Typically 0.1-0.5% with WS-23 at 0.2-0.8% for extended cooling endurance.
Does cooling agent survive mouthwash matrices?
Yes – WS-23 remains stable in aqueous-ethanol mouthwash systems at standard dosages.
