💧 Because rose water is a water-based ingredient, it needs preservation, especially if you're using it in DIY skincare like lotion, serum, or toner.
🌹 Here's the breakdown:
✅ Commercial rose water
-
Usually already contains a preservative (natural or synthetic), especially if:
-
It has a long shelf life,
-
It’s sold in stores without refrigeration,
-
It's labeled as "cosmetic grade."
-
⚠️ Homemade rose water (e.g., from boiling petals)
-
Contains no preservative unless you add one.
-
Can grow bacteria, yeast, or mold within 3–7 days, even if kept in the fridge.
🦠 Why this matters:
Any time you're using water, rose water, aloe juice, cucumber water, etc. in a recipe:
-
You must add a preservative or use it immediately and store it in the fridge for a short time only.
-
Without this, the product can contaminate your skin or cause infections.
✅ Tip:
If your rose water bottle says something like:
-
"Ingredients: Water, Rosa Damascena Flower Extract, Potassium Sorbate"
Then yes — it already has a preservative and can be safely used in formulations.
If it's homemade or food-grade (like for drinking), be cautious — it might not be preserved for skincare use.
