Not sure where are you located, but note that Ethoxydiglycol is allowed only up to 2.6% in sprays in Europe https://echa.europa.eu/cosmetics-restricted-substances/-/legislationlist/substance/100.003.563

This post is obviously just a sophisticated ad of the website attached in the text

Wee need report user/message feature. The forum has grown and first spam messages already here.

Sorry, but I can’t believe you have ever prepared this formula. Salicylic Acid 1% will not dissolve in water solution.
Also, Alpha Arbutin requires 5-7 pH value to be stable and Lactic Acid is mostly neutralized in this pH range.
-
Nothing wrong, these gel-formers do not tolerate low pH and electrolytes. It’s better to read recommended usage from manufacturer before trying.
I would suggest to use gums instead. For example Xanthan Gum, very reliable thickener. Or Hyaluronic acid (high molecular).

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?))))
-
Your response is such a deja vu to me..
I have a lot of conversations on reddit where people spam me with one-minute googled titles of studies and I spend hour to read them and explain why those studies are irrelevant.

How can we report this user for ads?

Sorry, but your friend ether lying to you (because no way SA can be soluble in this solution) or has no clue of what he is doing. It is too many actives to combine in one product and they are not compatible in terms of pH.
BTW what is the pH of your product?
-
You can always check the products on the market. For example I googled several two-phase hair sprays and found that they all use combo of some volatile silicone (like Cyclomethicone) + cationic surfactant (like Cetrimonium Chloride).

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?
-
https://patents.google.com/patent/EP0831768A1/en
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
