I wouldn’t use both in the same formula. I know some people claim Niacinamide can be used in low pH formulations, but I still think it doesn’t worth it. Several reasons:
- Suggested pH for Niacinamide is around 6.0. That’s because Niacinamide has nicotinic acid as impurity and lower pH will boost burning sensation and irritation from it. There are some forms sold by. for example, makingcosmetics, where they claim it has much less of impurity comparing to normal niacinamide.
- Acids cause irritation. Niacinamide in big doses does it too. Combining both together increase irritation even more. But of course it depends on the percentage.
- Products, which usually combine niacinamide and big percentage of acids, have niacinamide at the end of the INCI list near preservatives, meaning it is just a claim ingredient and added in 1% or lower.

Saturated SAP solution is slightly yellow. Here is the image of Revuele 15% SAP serum (quite saturated, see image attached).
One thing no one said is pH adjument. SAP gives quite basic pH and is stable in pH around 6.0. Consider to use citric acid to lower pH.
Revuele formula uses HA to thicken the serum and citric acid to lower pH

How I imagine this works:
Alginate mask is very thick rubish-like (when hardens) coverage. It basically creates a compress which prevents water to evaporate. So if you apply some watery products underneath, the mask will create heavy occlusion and potentially allow the serum to go deeper (because water stays in and the skin kinda swells with the product).
Also, it is somewhat heavy, so it’s weight kinda pulls and stretches the skin down and makes it more smooth temporary.
This is not basked with any science, just my perception of it. And of course no actives from the mask itself goes into the skin, they are locked inside the mask itself, right? So it’s pure marketing.
I guess the same effect can be achieved if put some hydro-gel mask and cover it with plastic wrapper (occlusion part) and some heavy towel or cloth on top (stretching part)

Yes, I tried to play with it. It gives totally unusable formulas. For example it suggested me to dissolve 2% salicylic acid in water. Obviously, it will not dissolve. And as a software developer I understand that ChatGPT is just a compilation of sentences from internet without actual understanding of the material and not always meaningful.
I am more into image generation networks. For example my avatar is not real photo, but generated with a neural network which was trained with my fotos.

Most skincare products add 0.01% of natural ingredients just for marketing. 1% INCI rule allows to put them closer to the start of the list to make people think there is much of it.
Another option is just a perfume.
There are also refined versions of ingredients, like refined shea butter or lanolin, which doesn’t have the smell

As a DIYer I usually see that non-neutralized carbomer is used and then TEA added causing the liquid to jellify. The process produces much less bubbles.

Usually they say UP TO 24h, which means any value but not longer than 24. If you put up to 100000 hours it is still valid, no matter how long it lasts.
Another option is 24 hors *, where the star is “instrumental test” on the back of the label, but what kind of test - not sure. I guess it doesn’t really matter and can be any stupid test

Sucrose is the scientific name for table sugar. Table sugar attracts bees and bugs.

Not a professional from the field.
As a customer I like fragrance free products, like serums, creams, lotions etc. BUT deodorizing body spray I expect to be fragranced, the format kinda implies it should contain one in my opinion

Reduce glycerine or add some silicones

The cooling effect is usually provided by menthol, but I don’t know if it is safe to use around eyes (although it is used in intimate lubes, so probably menthol is safe).
Another option could be Lecigel. Seppic claims it gives cooling effect to skin when applied

Why not just use regular animal shampoo then? What the point of applying “degresear”? Shampoo is already a degreaser

LinkedIn is not actually a forum, it is a social network for job searching, right?

The first column is a ratio of water to alcohol:
1 - 100% water, 0% ethanol
0.7 - 70% eater, 30% ethanol
…
0.3 - 30% water, 70% ethanol <- your solution.
The second column is solubility per liter. According to the chart it is 191.28 g in 1 liter of 30% water, 70% ethanol solution. Or 19,13g + 100ml solution. Since your solution is not 100% pure ethanol-water mixture and SA also counts in your formula, it seems 14% is too high
-
It will crystalize eventually. Also, the lower ethanol content - the lower penetration (but not sure if it is important for ethanol over 60% content)
You can check solubility of SA in ethanol-water solution of different proportions in study called “Solubility prediction of salicylic acid in water-ethanol-propylene glycol mixtures using the Jouyban-Acree model. (see attached image).
As you can see water presence decreases the solubility dramatically.

I see a lot of recipes like starch+vinegar+glycerin to make DIY biodegradable plastic sheets in a mold. How sorbitol and propylene glycol affect the end result?
-
It happens after a few weeks. Of course the process is gradual, but I notice the huge difference in color after few weeks
-
Does it happen in the Dark as well?
Yes
what kind of water are you using
Bottled distilled water from one of suppliers
adding other ingredients that have a bigger load of iones like Xantan for example?
Indeed, in one formula I add a bit of Xanthan. But the green reaction happens even in pure water.

How much does the generated picture look like you
It looks 80% like me in real life. Some details of my face are omitted and people say I look kinda “robotic” on this image, not a natural look.

Hi! Thank you for the response, I am very curious of how this “detective” story ends))

As I understood from media, now it affects products, meaning it is not possible to sell a product with retinol > 0.3% in EU. Previously, it was possible

Here is a link to reddit https://www.reddit.com/r/EuroSkincare/comments/14d4xyp/retinol_ban_in_the_eu/
The title is a bit wrong, but It contains links to documents.
This news is also all around social networks right now. The rationale is that EU lowered the rate due to people’s overall consumption of Vitamin A (including food).
If it doesn’t do much, why to regulate it then?)

What are your results? It’s very interesting to hear

No, silicones are not soluble in water. You need to emulsify them. Dimethicone should be fine
