Please help a dummy understand formulating with ceramides.

Evonik recommended it not to store it below 10C. -
@ngarayeva001
I have just looked up the storage recommendations of Evonik on UL Prospector, this is what it says:Storage
• The product is stable for 1 year when
stored at 10 - 15°C.• Kept at room temperature the product is stable
for half a year.
• The product should not be stored at temperatures
lower than 10°C. -
@Doreen, I just checked Evonik complex. It has a bit different LOI than the one I was talking about. I bought an identical complex (the only difference is the country of origin) from the lotioncrafter and from makingcosmetics. They both send it wrapped in ice (that obviously melted by the time I received it) and labelled it “to be stored for 6 months under refrigeration“.
Ceramide NP (and) Ceramide AP (and) Ceramide EOP (and) Phytosphingosine (and) Cholesterol (and) Sodium Lauroyl Lactylate (and) Carbomer (and) Xanthan Gum.
Good to know. I thought all ceramides should be refrigerated.

The LOI you list is the same as the SK Influx.
I have attached the Evonik data sheet, hopefully it’s helpful.

You are right. They are the same. I wonder why makingcosmetics and lotioncrafter recommend to store ceramides in the fridge then..

Thanks @Doreen and @ngarayeva001 for the info!
Frustratingly, I don’t think I’ll be able to use the SK Influx as I’ve been patch tested at the dermatologist for different skin sensitivities (a major issue I have) and reacted badly to carbomer (which is part of the ingredients of SK Influx).
I realize it’s a very small amount of carbomer in the total product, and even smaller when you’re adding a minimal percentage such as 3% to a formula, but I’m not sure I feel comfortable putting it on my face given the reaction my skin experienced (bright red stinging + acne). Yikes!

Wow - every single bit of this thread was well worth the read. Thanks to @MJL from a fellow “dummy” for eliciting all the good info, to those who shared their experiences and to @OldPerry for sharing the studies and the examples of the critical thinking we should have about them.
I just pulled the trigger on some of the LotionCrafter product and was curious if @Doreen or any others could elaborate on the incompatibility with cationics mentioned in the LotionCrafter description. Like, what bad will happen if say, this was used in a product with BTMS or PQuat-10 (not that I’m thinking of pressing my luck, at the price of this stuff), and how much, if any, can it tolerate before the horrible, Earth-ending bad thing happens?
