It’s best to dilute the suspected ingredients and patch test.
-
I believe Hyaluronic acid is anionic, you can check if the cationic version is available.
-
Have you tried Sepinov EMT 10, or perhaps if your formula doesn’t contain any electrolytes, maybe make use of carbomers where there are electrolyte sensitive. They should break down with sweat.
-
What other gelling agents do you have?
-
Depends on how irreplaceable they are. If they are replaceable, then the fancy ones are not worth the hype.
-
It depends on how you want to market it. Ingredients can be part of the marketing, so you can determine for yourself if it’s limiting your marketing ability towards your demographic.

Did you try adding some fatty alcohol to see if the effect reduces.
It sounds like the “quick break” effect. It’s an effect that some people may want, but it depends on the requirements. Eg, https://sunjinbs.com/?p=4620

UV filters for sunscreen can come in powder / solid form, so the esters / hydrocarbons can help to solubilize them to incorporate into a formula.
-
You can follow the product and use Xanthan Gum, if not other thickeners like Sclerotium Gum should also work but would more more expensive.
The issue would be the ingredients that contain sodium, the Saccharide Isomerate might contain Sodium Citrate as an additive as well, so it’s something to take note if you are adding that.
-
What are the steps and phases?
-
You can consider trying a less thickening emulsifier like graillotion mentioned. It depends on your choice, you can go with 165, or Montanov L or 202. Maybe you can also consider adding more humectants that has a different skin feel like Betaine.
-
Probably the combination of surfactants are not suitable. Can’t comment too much about the essential oil, some people might break out from having oils in their cleanser as well, so it’s something that you will need to figure out.
-
What aspects of “wrong” are you trying to ask about?
-
What does your 100% concentration refer to? That the total formula should add to 100%? or the purity of the xanthan or glycerin should be 100%?
-
If it’s a lower quantity, perhaps you can purchase from a repacker, myskinrecipes has both and can ship internationally.
-
The phases look reasonable, but the matcha may cause some issues, so you can consider taking it out if you find that it oxidizes too quickly.
-
The xanthan gum + glycerin + panthenol may be a sticky combo, so you might want to test it out. If you are using 1.5% hyaluronic acid, you may not need that much additional xanthan gum.
The vitamin c may not be in the compatible pH range with the niacinamide, so you will have to consider the choice of vitamin c.

You can take a look at this article https://www.ulprospector.com/knowledge/9837/pcc-how-to-improve-the-bioavailability-and-efficacy-of-skin-care-actives/
-
You should be able to see on the brochure here.
-
If you have to use the electrolyte ingredients, you can look at the carbomer options but you have to tweak it really well to have a good balance between stability and breaking, with the support of the Sepinov. Have you tried Ultrez 20 or 30? I didn’t use too U20 too often because of the wetting time (I prefer to make my batch faster) but it would be my alternative.
-
I understand what you mean since i’m in Singapore, it’s humid here as well. My formula doesn’t contain much electrolytes, which is why mainly use Sepinov, if not I would use the electrolyte sensitive polymers so they can break on the skin when I sweat to give it the quick break effect to avoid the sliminess.
-
Did you continue stirring while the hyaluronic acid hydrates? Just wondering about that.
-
Sodium lactate should also be fine but i didn’t suggest it because I’m not sure how electrolyte sensitive the emulsifier blends are, and if they may go overboard with it. Does it also produce a film on the surface like Betaine does? I find that it’s more penetrative or deeply hydrating instead.

Well, it depends on the pH requirements since it will impact the following:
carbomer
urea
Glycolic Acid
Salicylic Acid
Vit b3
vit b5
Lactic Acid
Zinc oxide

They are from Thailand, there should be others that are on the forum that have bought from them before besides from myself for smaller quantities. I’m not too sure about the source perhaps you will have to ask them since there are different manufacturers producing them.
