Adding heat sensitive ingredients
Hi, I was wondering if anyone had any suggestions as to how best to add heat sensitive ingredients to a batch. I have a couple formulations which use ingredients such as Vitamin E, dimethicone, Germall Plus and Panthenol (d/l) when I cool a larger batch down to “safe temperatures” the viscosity becomes much higher and mixing is very difficult with larger batches. I want to ensure good homogeneity with these cooldown ingredients but I am never completely happy with the mixing method. I have used a paint mixer on a drill and a bread mixer at times. Scaling up to large scale equipment is quite costly especially for formulations which might not be viable after stability testing etc..

Dimethicone doesn’t need to be added on the cool down phase. And you won’t notice any formulation difference if you add Panthenol hot either. But it all comes down to the quality of your mixer.
