Is it some kind of two-phase product to shake before use? If so you don’t actually need an emulsifier. Shaking will disperse the oil and create temporary emulsion

I found the exact INCI:
- Water 50-75%
- Lactic acid 30-50%
- Sodium Lactate 5-10%
- Magnesium Lactate 0.1-1.0%
- Calcium Lactate 0.1-1%

I thought saponified oils is basically another term for a plain soap…
-
And?
You can say this about any skincare ingredient, even water.
What is your point?

I like how they marked Xanthan Gum as “sourced from non-GMO plant”. Does it mean everything else is from GMO-plants?))))
-
Well it is obviously fake. Azelaic Acid is poorly soluble in water so you need a solvent. Solvent would be preceding Azelaic Acid. Also Ascorbic Acid is not stabilized and would oxidize in days giving color. Plus Carbomer should be neutralized to gel, but the product has a lot of acids and probably is meant to have low pH. So I don’t think this product is legit

What do you mean? Fatty alcohols have been used for ages in o/w emulsions as structuring agents.
Edit: Sorry, I misread, you mean w/o…

Thank you both! Now it is clear to me

Perry and Valerie answered this question in episode 326 of the beauty brains podcast

I see you’re into neural network these days. Try stable diffusion network (there are many tutorials on YouTube, search dream booth). It can generate photo of you in any amplua by textual description. Makes appearance even better than Glycerin ????

I think they just added two masses like it is one molecule. But as I understand cetearyl alcohol is not a molecule but a mix of ingredients? I am not a chemist and I am not sure if molecular weight can be applied to a mix of ingredients?

Once I had an experiment to mix salicylic acid with poloxamer liquid. It reacted to form lumps of gel in water. So you can try this to check if it Poloxamer in bought solution. This also described in https://patents.google.com/patent/EP2242476A2/en:
For example salicylic acid can cause Poloxamer to gel

Not sure what’s wrong with your ingredients, but Azelaic acid is soluble in pure PG. Here you can see it: https://youtu.be/VssxLD7skQA

Ah, I see, another clean beauty ad.

This is very helpful, thank you! I checked SDS on DeLonghi one and found only the pH, not concentration. Maybe I overlooked it:
But they also provide density, maybe I can calculate how much acid based on density.

FDA is only valid for USA though.

Under pH 2.5 Lactic acid is about 96% acid and 4% Sodium Lactate (if neutralize with NaOH). It can be in different amount:
1. 20% water, 76.8% Lactic acid, 3.2% Sodium Lactate
2. 40% water, 57.6% Lactic acid and 2.4% Sodium Lactate.
Both formulas have pH around 2.5.
What I am wondering is how much acid is usually used in descaler solutions.
-
I’m confused, what is revolutional in your post then? Liquid soap is a product of ages.
-
Interesting! But why to encapsulate oils in a cleanser? Does it suppose to break down on skin during wash to nourish?

In this patent then say you can dissolve up to 10% of Azelaic Acid in pure PG.
-
Of course it can. The problem comes when you add water. If your formula is pure PG - then many substances (like Salicylic Acid, Azelaic Acid) have no issues with solubility.
-
Sodium Hydroxide is close to EDTA, so it should be in small amount. But this INCI list is all questionable and we can’t make assumptions on ingredients position I guess
-
I am eager to hear.the answer, this question bugs me the whole day and I can’t find easy answer on the Internet
-
I see your point, but could you explain how it actually should be calculated? I tried to search what is molar mass (I still suspect molecular weight is wrong term since as I understand cetearyl alcohol is a mix of two substances in some ratio) of mixes but can’t find easy answer.
-
I just googled “what molecural weight has cetearyl alcohol” and every website claims it has 512+…
