Practical advice for using highly viscous ingredients
I am climbing the “scale ladder” so to speak and some of my formulations will be made at a much larger scale. How do some of you handle viscous compounds such as Polysorbate-80, Decyl Glucoside, CDEA and Polyquat 7 ?
D-Panthenol has been especially difficult to handle. I feel like I am losing quite a bit in transfer losses. Luckily I don’t need to currently use this ingredient in my larger sized formulations but I really struggle on how to efficiently measure and pour this particular ingredient.
What I have been doing is weighing a larger amount than needed into a sterilized beaker and then pouring the necessary amount by simply measuring the weight of what is left in the beaker. I don’t like the idea of re introducing unused raw materials to their original containers.
Any tips would be greatly appreciated.

If they’re water soluble materials, try weighing out what you need into a larger vessel than necessary and premixing with 2-3 times volume of water - should work with panthenol. For polysorbate-80 & decyl glucoside, I’d suggest gently warming them to lower the viscosity - a water bath is good for this.
