Using Thyme Care™ at 1% instead of 0.8%: Effects on Scent and Irritation
Question
Regarding the ingredient Thyme Care™, the recommended usage concentration for germ control is 0.8%. Can I use it at a higher concentration of 1%?
If so, what effects might this have on the product, specifically concerning:
- Efficacy in germ control
- Potential for skin irritation
- The resulting scent of the product
Answer
Based on the information, using Thyme Care™ at 0.8% is sufficient for effective germ control in cosmetic formulas, as confirmed by MIC and Challenge Tests. While using a higher concentration like 1% might be easier for calculation, the primary reason for recommending 0.8% is to minimize the strong natural scent of Thyme Care™. The product description and previous staff reply indicate that Thyme Care™ does not cause skin irritation. Therefore, using 1% is unlikely to cause irritation, but it will result in a significantly stronger scent in the final product. It is recommended to use the effective concentration of 0.8% to balance efficacy with product aesthetics (scent).
