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

Not a chemist by as I understand any organic acid will react with metal ions? I mean coffee machine descales are usually citric or lactic acid. Also Citric acid is usually mentioned as weak chelator.
There is an option of Sodium phytate, not sure if it can be used at low pH, but lotioncrafter says it works under pH < 6: https://lotioncrafter.com/products/sodium-phytate

Pure ascorbic acid can react with niacinamide under low pH giving yellow Niacinamide Ascorbate: https://skincarewithfriends.com/niacinamide-and-vitamin-c-derivatives-conflict/
But Ascorbyl Glucoside is not pure Ascorbic acid and is formulated at close to neutral pH, so I don’t see any reasons they can’t be combined

1. It is impossible to answer without knowing your FULL formula
2. 10% polysorbate will give foaming. It is a surfactant after all. Usually used to solubilize a SMALL amount of oil soluble ingredients (extracts). In high amount it gives unpleasant foamy feeling.
3. PEG-40 Hydrogenated Castor Oil is somewhat more aesthetically pleasant

As an owner of oily skin type I can say ANY occlusion may cause increased number of pimples. So you should not worry about that, usually natural oils and butter are more acne-prone than synthetic inert materials.
When it comes to Dimethicone and Petrolatum I would vote for the latter. Dimethicone leaves a noticeable film and it can peel. Many people with oily skin type don’t like silicone feeling on the skin (personal observation).
In terms of marketing both ingredients are demonized on the Internet, no win if you use one or another.

You made an acidic product, no wonder it stings at sensitive areas
-
Some oils have some volatile silicone mixed in which allows to decrease oil content and improve spreadability of the product. Thinner film - less greasy
-
If you can afford to make a second batch of the same weight and then mix them both together you could average the percentage to the required specs.
Basically x = 11.4, y = 37.0, z = 38.0

The sediment is most likely Salicylic Acid. It is almost insoluble in 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
-
Not as available for DIY as plain Urea, but you could try to search it’s trade name - Hydrovance

If we make a new batch of the same size and mix it with the original one we will have a double-size batch with averaged percentages. I mean if you take 1g of 10% solution and mix it with 1g 20% solution you will get 2 grams of (10+20)/2 = 15% solution.
The equation is: (original + adjusting) / 2 = target
We know original solution, we know target solution. We can mark adjusting solution as x (y,z, etc) and create an equation. Let’s make one for water (I guess it is the first ingredient):
(64.4 + x) / 2 = 37.9
You need to solve this equation and you will find the numbers:
64.4 + x = 37.9 * 2
x = 37.9 * 2 - 64.4 == target * 2 - original
