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..
