To me Sorbitol is much stickier and more costly to buy than just Glycerin
-
I remember AXE advertisement in my country where a guy was spraying it all over the body in shower and then girls were literally sticking to him. So yes, I think it is just a marketing.
There might be some ingredients exposure limits (like it is allowed only under pits, but the whole body is too big surface and exposure) but I doubt it

People earn money with this and you want get it for free?)

No

Your life is so wild ????

Simple answers:
1. No, most customers do not care about preservatives (and INCI in general)
2. To compete with big brands the small ones have to come up with marketing stories, one of them is fearmongering about preservatives (and other components like SLS or silicones)
-
Glycerol/Glycerin and Xylitol are sticky.
-
I guess it is a lotion that you apply in shower on wet skin before the towel
-
Why not using plain old SLS? And thicken it up with table salt?
-
Are you sure it is Betaine Salicylate and not Allantoin? 2% is very high, Allantoin has weak solubility in water, I usually add not more than 0.5% of water content (not the whole formula). Try making a test batch without it and see if it helps

I don’t have an exact answer, but my limited chemistry knowledge says that:
1. Weak acids react slower than the strong ones. Maybe some very weak acid + baking soda will react long enough?
2. Speed of the reaction depends on the temperature. Cooling down the medium will result in slower reaction
Also, another approach could be if you have some equipment to slowly add acid to the baking soda

why is this one stabile?
Is it? Have you ever had it? How long did it take for you to spoil? Based on the reviews I’ve seen on the Internet it is not stable.
From the INCI I see they use Sodium Sulfite as an antioxidant that should keep AA stable, but I doubt it does it for long time (since there is 23% of AA). They might also have very acidic pH, below 3, that helps to have AA not protonated and therefore more stable in water.
If you want to make an AA serum you can go several ways:
1. Skinceuticals formula, where Ascorbic Acid is paired with Ferulic acid and mixed Tocopherols and most of the water replaced with Ethoxydiglycol. (you can read up on it here or on the internet).
This formula is used in many other famous products too: Timeless, Geek & Gorgeous etc.
2. Waterless formula. The main problem is water, if you remove it - the solution will be much more stable. There are several ways, one is to get dispersion of AA in silicones, like The Ordinary does with 30% AA cream and L’oreal with 10% small tube. But this is hard to achieve in DIY setup.
3. Waterless formula with Propanediol (not propylene glycol). You can get 12% of AA + 88% pf Propanediol solution or if you add Urea you can get up to 20% of AA in Propanediol+Urea (the product is Matter of Facts serum)
4. Do fresh batch frequently. There are some DIY suggestions to make a tiny batch once in few days and store it in the fridge in opaque bottle. If you have scales and all you need to to mix AA with water it is not as bothersome.

Depends on what property of mineral oil you want to mimic. Cetiol CC (Dicaprylyl Carbonate) can be used as a liquid lightweight emolient, or Hydrogenated Polyisobutene if you want good occlusion
-
It is stated in the comments - iron ions from bentonite, salicylic acid reacts with iron and creates this purple color.
If you get same result without bentonite that most likely you have water not deionized enough

Hi Perry!
Are there any rules on the forum?
I see the OP all over the forum promoting his brand. Is this allowed? -
Yes
-
Hmm, not sure why you answered to this comment, but I was answering to the topic starter. No one was talking about you and your business.
-
Don’t ruin the moment of fame for the guy. He’s been 40 years in science and even has become a co-founder of a company just to write these titles in every message on this forum)
-
It may be compatible or lose viscosity over time, do stability testing
-
It means the opposite, metal ions decrease viscosity
-
Metal ions can break polymers like Carbomer. That’s why many polymers are advertised by showing viscosity with added table salt (NaCl)
-
The reason they are less sustainable is that you have to spend a lot of water, soil and processing power to make natural ingredients. Then shorter storage time and quick spoilage leads to more amounts of waste.
Synthetic ingredients are easier to manufacture, control quality and store. It requires much less resources and processing power.

I can say Niacinamide 10% or 0.01% ???? Just tested 2 solutions, the one with 10% gives me a flush

If you ask about Benzyl Salicylate then it is a fragrance additive I think
