Is this the poor man’s option?

My guess is you won’t find that product from a repacker. CP Kelco (now Tate & Lyle) is one of the only manufacturers I’m aware of for personal care, and Lubrizol is the exclusive distributor. It is also known as diutan gum, so you may have better luck searching that. The high acyl product you linked is pretty different, what is the application/intended use for the polymer?

Yes…as a polymer @evchem2
However, with something a little bit more specific aspects in mind. I am making a viscous cream, which currently has a melt point around 38-39C. As a product that might spend some time in a brown truck (UPS) during shipment…and potentially hitting those kind of numbers… looking for some heat stability (not losing its form during shipment, which may facilitate leakage from the container)…otherwise the formula does not need this ingredient, as I already have Cetyl-HEC in place. Their marketing promotes thermal stability as well.
I do have one other question… the marketing made an interesting claim of …. “Its anionic character allows enhanced compatibility with cationic ingredients.” As my formula has 1.5% BTMS 50 as part of the emulsifier (balance is non-ionic) ….. would this gum be ‘compatible’?
Gellan gum… seems to be sourced from the same thing….so as long as the acyl type is the same…. would you suspect them to be ‘interchangeable’? I was able to find a blurb…. where George Deckner seems to pull back the curtain….and use the language interchangeably. I know the brand linked above… on another product I use…. they source from Sisterna…and I get identical performance…buying the Food grade (lower price) over the cosmetic grade.
Aloha, and thank you for your time and consideration.

Both should help with heat stability- high acyl gellan forms a gel around 85-90C and sets close to the same temperature. Diutan is commonly used in oilfield drilling fluid and has good high temp stability. The anionic compatibility is not great with BTMS ( I suspect the fact both have to be in the batch at high temperatures doesn’t help), if you have some salt in your formulation that helps shield the charges. What is your target pH?
Are you asking if high acyl gellan gums from different suppliers/SKUs are interchangeable or if diutan and high acyl gellan are? High acyl across different suppliers? Likely similar performance, there’s less variants that I know of compared to xanthan for example. The higher the use level the more you’ll probably notice sensory differences, high acyl gellan can start to look a bit chunky but will likely have a lighter feel than diutan.
Generally for these fermented products the main difference between food and cosmetic grade is microbial burden (food grade will have higher plate count spec).
