Let’s compare humectants!
-
Btw I like sodium PCA too and I think it’s similar to lactate, but PCA is several times more expensive so lactate wins.

I tried adding 3% of sodium lactate to my emulsion, and it doesn’t smell great (sea salt + stale smell combined, I’m not great at describing smell though, but it is not a pleasant smell). The scent did go away after a minute or so but i’m wondering is there a way to mask of the scent without using any fragrances. What is your experiences though?
I did like the way it felt on my skin. And i tried it plain as well, and it definitely surpass glycerin and other glycols in terms of skin feel and moisture. It felt very hydrating without any tackiness (but smells awful)
Are you using powder Sodium Lactate or liquid?
I use 60% liquid as well

ngarayeva001 said:I use 60% liquid, but want to try powdered version too. I really like it but I also like carbomers and polymeric emulsifiers. Unfortunately these are not compatible with sodium lactate. If there’s one humectant that feels different (again as per my anecdotal experience) its sodium lactate. Re smell, it’s not that repulsive to me, so I kind of ignore it. Maybe I just got used to it, as it’s in the moisturizer I use everyday..
I am waiting for my sodium PCA to arrive, and yes the price difference is real. Will have to compare then. Does sodium PCA has an odor to it like sodium lactate does?

I’ve been using Zemea/Propanediol as the main humectant in moisturiser I’m trying out. Seems OK but I’m keen to try glycerine for a comparison.

@Pharma for what reasons you prefer xylitol over sorbitol?
-
@Abdullah Lower melting point, lower viscosity of NADES and often higher flexibility as hydrogen bond donor, hence easier for me to work with

Another interesting one to add - Gobiotics preBIULIN AGA (inulin). I’ve only tried it at 2% in water, and not in a formulation. To me it is more hydrating, softening and long lasting than glycerin (against 2% glycerin in water), but there is a very slight sugary, sticky feel that develops after 10 minutes or so, whereas the 2% glycerin feels completely “clean” on the skin. I’m not sure it’s usable due to the sticky feeling… I think I would still feel it even if used at <1%. It does seem to continue hydrating over time though, as per their marketing.

I use pure Inulin (Inutec) in my lotions at 2 - 3% and I’ve never noticed any traces of stickiness.

Hi @ggpetrov, is “Inutec” the full name of the product you use? I couldn’t find an inulin with that name… only “Inutec H25P” (substitute for cationic conditioning polymers) and “Inutec SL1” (stabiliser). I have Inutec H25P but it was also sticky. Thanks.
-
Yes, Inutec H25P
-
ggpetrov said:Yes, Inutec H25P
Thanks, I will try Inutec H25P again then. I only briefly tried it mixed with water.. I didn’t actually try it in an emulsion.

Does anyone know acetamidoethoxyethanol aka ElfaMoist?
-
Has anyone tried or have any feedback for Sodium Polyglutamate (Polyglutamic acid) or Sodium Acetylated Hyaluronate?

I wonder about the stability of the emulsion if I add sodium lactate at 2% since it is an electrolyte, my second concern is sodium lactate is a little exfoliant at 2% and wearing this cream and go under sun may give negative impact on skin, also I have a question could we add sodium lactate to shampoo formulations?
