Comparative Testing of Ingredients
Lise
This is a side by side setup for a small batch of shampoo bars. Ingredients are identical in both except for the guar gum. I’m trying to see if there will be any discernible difference - how they are to work with, and how they perform in the final product.
It’s always a good idea to have a ‘back-up’ supplier of ingredients - no matter what you work with - as cosmetics ingredients can disappear in the wink of an eye - most particularly if they are green and trending.
More to Come!
PS. I wrote about how guar gum isn’t always the same thing right here.
Do Tell
Do you do side by side tests to compare ingredients?
