Using Lavender Water as a Cream Base and Preservative Needs
คำถาม
When using Lavender Water as a base for making cream instead of distilled water, is it still necessary to add a preservative? If so, how?
คำตอบ
Using Lavender Water as a Cream Base
When using Lavender Water (Lavandula Angustifolia) as the base for your cream formulation, you might not need to add an additional preservative if you are using it as the main ingredient (over 60% of the formula). This is because the specific Lavender Water product you mentioned already contains Phenoxyethanol at 0.8% as a preservative added by the manufacturer.
However, if you use Lavender Water at a lower concentration (less than 60%) or if your specific cream formulation requires additional preservation based on a challenge test, then you would need to add a suitable preservative. The choice of preservative depends on the pH of your final cream and other ingredients in the formula.
Some examples of broad-spectrum preservatives that could be suitable, depending on your formula's pH and requirements, include:
- Mild Preserved™ COS
- Global Guard™ 221
- NaturePreserve™ LB2
- Preserve-BSB™
- Coco-Preserve™
It is always recommended to perform a challenge test on your final product to ensure it is adequately protected against microbial growth.
