Orange/red layer in cream
I have been struggling with scaling a cream formula. Both jars contain the same formula - however, the jar on the right was made in a small batch.
Went ahead and tried scaling it to a larger batch and noticed within a day or two, that it had an orange/red top layer and was wondering why that was.
Preservative used is caprylhydroxamic acid at 1.1%
Essential oils used are sweet orange - 0.15% , bergamot (bergapten-free) - 0.25%
Xanathan gum - 0.3%
Emulsifier - Olivem1000
Glyceryl stearate - 1.5%
Colloidal Oatmeal - 2%
I am guessing it can’t be the formula - since the exact same formula seems to be holding up alright when made in a small batch.
Has the second batch not emulsified well enough? Has the oil and water phase not been heated to the right temperature in the bigger container?
Also, the first batch was emulsified in a glass container whereas the second batch was done so in a stainless steel container.
What could be wrong? Is it oxidation or bacterial? It seems like the orange layer starts at the top but over time spreads to the whole jar.
Ph for both jars is the same at 4.5.
Really appreciate your input!!
