Why does the cream evaporate when in a closed jar and have humectant ?
I am making cream with the following formula:
- Water: ~80%
- Propylen Glycol: 4%
- Aquagel 45 (Laureth-7 & C13-14 Isoparaffin & Sodium polyacrylate): 4%
- Lanolin: 3%
- Jojoba oil: 9%
- Pigments: 0.2%
- Prevasertive: 1%
I’m packing by a jar with a screw cap. the cream contains 50% of the jar.
When i test for stability at 40c, water droplets appear on the lid of the jar.
What should I do to fix this problem?
