Few minutes of irritation with Polymeric emulsifiers & thickeners
I prepared different cream gels using either lecigel (1.2-1.5%) or sepinov emt 10 (1%). In all these formulations I added sepimax zen (0.5 to 1%) towards the end for additional thickness.
Oil phase not more than 2%.
Immediately after making cream gel if I apply over my skin I feel this tingling and urge to itch kind of feeling. However, it goes away after a few minutes.
I apply these preparations few days after making them and my skin doesn’t react the same way. Although I still get a little tingling.
So my question if polymeric emulsifiers are used in a formula (with no other emulsifiers or thickeners) then should the preparation be not used immediately and left for few days?
