I would recommend removal of the Stearic Acid. You have no alkali to help saponify and you already have a good emulsifier in the GS/PEG100. Plus the Shea butter should have a high level of SA already. Also Liquid Germall is heat sensitive, it not is recommend to go above 50C. So make sure to add it as it is cooling down after emulsification or you would lose efficacy.
As for the temperature increase stuff, I don’t see how the seasons would play a role, unless you are formulating outside? It could play a role depending how you are storing the sample. Are you putting it in the heat and in direct sunlight? then sure, there could be issues from that. Temp and humidity certainly play a role but I don’t imagine natural seasonal change would be causing such a big difference formulation-wise, especially if you are in a climate-controlled room as I would hope. Did you switch to a new supplier? are these different lots of materials from those batches; or are the same and have expired/been contaminated? Did your method change? Did your workspace change or are there new possible contaminates? I would not question the ingredients first if the formula worked originally because they’re chemical properties have not changed since last fall.

Hi, I would definitely recommend increasing the level of poly suga mulse. You are on the low end at 1%, where in a leave on product you’re within the recommendation to use up to 3%. If you don’t do it already, a premix would be helpful as well. The TEC shouldn’t be causing any issues, it is only slightly miscible in water, so it will take awhile to go in.

Hello, so the IU is specific to the compound in question. So the retinol IU only applies to retinol, if a product contains a different Vitamin A derivative or a different version of retinol (ex Beta-retinol, retinyl acetate) it will have a different IU. So it would follow the actual ingredient, not products.
I do not believe IU is exactly what you are looking for however. IU is a measure of the required amount to have a biological effect (i.e. 3 mcg = 1 IU of retinol) it is a specific measurement that is measured for food and supplements, I don’t believe it would be measured for skin effect. This is basically the reason that a company using retinol won’t put an IU, but just the %, compared to a Vitamin A supplement that may put it on there as its more applicable (or the updated “…mcg RAE”). If it helps you think about it more clearly, then by all means, it is just a conversion to a different unit, but I think it is an unnecessary conversion to make in your head.
