Sugar alcohols
I notice Shiseido uses Xylitol, Erythritol and Trehalose together in some of their facial moisturizers.
Don’t they all perform the same function as a humectant? Is there any noticeable benefit in using a combination? -

Perhaps it is in reality some ferment product they have that just happens to contain a mix of those three sugars. I think sometimes we tend to read too much into an LOI.

I think @Belassi is right. We do a lot of tech scouting for competitors products and actually figured out for one product that 1/3 of their LOI was contained in one ingredient. There were things under 1% that would be added 5-20% traditionally and the reason behind this was they were using the mixture at <5%. If you look at the ingredients see if anything is unusually low in the list and it might be a combination of several things, then look around at the suppliers to see if those ingredients are contained in any one material they offer. Sometimes a hint is seeing a preservative kind of high on the LOI and then another one or two pretty low on there. Even some of the pigments we use come with BHT in the raw material.

Several years ago I spoke with Formulators at a French company that was using that combination. I honestly can’t recall the company. They were using that combination to reduce Aw (water activity). They did Aw testing both during the R&D as well as part of QA/QC in production.
