How To Set The Right Level
- Start at the low end and increase until the desired strength is reached; the camphoraceous note is strong
- For medicinal use, follow the pharmacopoeia/regulatory dose in the finished product (e.g. injection concentration is set by the approved formulation)
- For food, always work from the minimum self-limiting level per GB 2760 flavouring principles
- Always dilute before skin contact; never apply undiluted
- Validate with stability and safety testing at the final concentration before launch
