Persistent Foam in PEG1500 and Pro Polymer Silk Gel Formulation
Question
I followed the instructions provided by the staff for using `PEG1500`.
The instructions were to first dissolve `PEG1500` in water, then create the gel texture using `Pro Polymer Silk`. After the gel was formed, I was instructed to gradually add other ingredients into the gel texture and blend or stir until dissolved.
Despite following these steps, there is still a lot of foam.
I have waited for a full day, but the foam persists. What should I do?
I used a hand blender for a 100g batch.
Also, regarding storage, which method reduces foam faster: refrigerating it or leaving it at room temperature?
Answer
It's common to get a lot of foam when using a hand blender, especially with ingredients like PEG1500 and gel thickeners such as Pro Polymer Silk. The high-speed mixing incorporates a lot of air into the mixture.
To reduce the foam:
- The best way is to simply let the mixture sit undisturbed. The foam will dissipate naturally over time. Since you've already waited a day, continue letting it sit.
- If you need to mix, use very gentle stirring by hand instead of the hand blender.
Regarding storage temperature:
- Leaving it at room temperature is usually sufficient for the foam to dissipate.
- Refrigeration might increase the viscosity of the gel slightly, which could potentially slow down the rate at which bubbles rise and pop. So, room temperature might be slightly faster for defoaming, but the main factor is just letting it sit still.
Continue letting your 100g batch sit quietly, and the foam should reduce significantly over the next day or two.
