If it stops sweat, then it becomes an OTC.

Sounds like a challenging project. You’ll need someone with access to some analytical equipment if you don’t already know the composition of the polymer. @chemicalmatt any thoughts?
-
Not a significant amount. The way SLS works it just does not form insoluble salts the same way soap does. The SLS micelles are just much more stable.
-
Raw material suppliers are not under the same regulatory scrutiny as finished goods makers. Essentially they can market their ingredients however they want with the flimsiest of evidence. They know they are not the ones ultimately responsible for claims made to consumers. I take what raw material suppliers say (even big corporations) with a grain of salt.
And winning awards at in cosmetics or another trade show is not impressive either. These awards are given out every year but the reality is that very little changes in our industry. There haven’t been significant innovations since the 1980’s in my opinion. But still they have to give an award for something. Sadly that something typically comes down to the best marketing story.

This may be the way forward for some innovation in the cosmetic industry (there hasn’t been any real consumer perceptible innovation in years).
However, consider me skeptical that this could make much difference. In my experience people are just terrible at noticing subtle differences in cosmetic products. You can make the greatest formula in the world and if you put the wrong fragrance in it, no one is going to want to use it. Conversely, you can make a lame formula that everyone loves just because it has a well-loved fragrance and a good marketing story.
This is also ignoring the legality of creating products that you know specifically impact the biochemistry of people. This would make them drugs.

Since there is no proof of any thing being Supernatural, isn’t everything natural?
-
As to how much of a ratio you use between surfactants, that is just a matter of experimentation. You want to balance performance with gentleness and cost. The ratio / amount is different with different formulas.
-
Typically, the containers you get from the packaging supplier are already cleaned and washed so you don’t need to do anything to them. At least that is the case for large scale producers.
-
They’re probably the same. You’d have to look at the specification sheet.
Most extracts are sold in Glycerin or Propylene Glycol. -
I’m confused.
Do they not think the cosmetic industry has already tried those compounds?
What do you see as the major problems with their study?
Also, to be fair, there are plenty of non-government, academic types who have published equally bad “research”

It really depends on the formula / emulsification system. 10% might be fine for some systems.
In fact, we used to do what was called a “quench cooling” method with one of our hair conditioners. We would add 25% cold water after creating the emulsion. This rapidly cooled the system so instead of taking 8 hours to make a batch we could do it in 2 hours. And we didn’t have any stability problems in that formula. -
I agree that the Glycols are helping.
And with the Baby Daily Moisture cream, they also list 1.2% Dimethicone as the active ingredient. This is actually an OTC drug product ( https://www.aveeno.com/products/daily-moisture-baby-cream ) My guess is that it has a low enough water content that Water Activity is also helping with preservation. Also, it is in a pump which helps and produced in an OTC factory which is going to be cleaner than your typical Cosmetic manufacturing facility.

You’re almost right! You’ve calculated correctly the amount need for 100g. If you want to make a 250g batch then you’ll need to multiply those numbers by 250/100 = 2.5.
SCI: 9.41g x 2.5 = 23.53g
Disodium cocoamphoacetate: 13.33g x 2.5 = 33.33g
Or if you wanted to make a 500g batch you would multiply those numbers by 500/100 = 5.

These are really just marketing terms. When I was working on a shampoo project and our marketing people wanted a “clarifying” version of our shampoo, we simply increased the surfactant level by 1%. Change color, packaging, and viola! You’ve got a clarifying shampoo.
-
Because bacteria and most other microbes can not grow in an alcohol solution greater than about 20%.
-
I’d guess shampoo A because it has SLS
-
If you use Cocamide DEA, yes, it’s possible. With Cocamide MEA, probably not.
-
Agree with @Microformulation - Minoxidil is a drug whether you make claims about it or not. You need to be certified to make products with it.
-
To get closer to a “store-bought” product, you first have to get rid of the ingredients that are either doing nothing or actively making your product worse. Remover (or reduce to <1%) the following….
Glycerin, Bamboo Liquid Extract, Date Palm Liquid Extract, Honeyquat, Panthenol Powder, Vegekeratin Hydrolyzed Protein.
Make that formula first and then see how your needs to be improved. With the exception of Glycerin, the ingredients I listed above are what we call “claims” ingredients. They are just put in formulas (especially shampoos) to give the marketing people something to talk about. They don’t actually work to do anything in the formula.
You don’t include Glycerin because it depresses foam and provides no real benefit to a shampoo.
-
Ha!
-
Yes, if they make that claim then it is an OTC. And if it is an OTC Antiperspirant, they have to use some form of Aluminium salt as the active & label it with a drug label.
-
This is an old discussion! But I say PQ-37 is better for leave in because you need to use less of it to get a reasonable effect. You could use 0.2% of PQ-37 that would give you the same effect as say 2% BTMS. So, this would result in hair that feels less weighed down.
-
Most shampoos don’t use a thickener like Crothix. Better would be something like Hydroxypropyl Methylcellulose. That helps with foam. Or you can just use Salt to thicken and use a cationic polymer like Guar Hydroxypropyldimonium Chloride for foam stabilization and conditioning.
-
You’re arguing something different than my point. My point is that saponification is not more natural than the process used to make SLES. In your way of looking at it, I would agree there are less steps, but that doesn’t make it more “natural”. It is still a man-made process that requires synthetic chemistry that isn’t produced in nature. They are both synthetic compounds.
I also disagree with your assessment of the safety of the ingredient and will defer to toxicologist opinions.

There are lots of people who ride around in cars without seatbelts and never get hurt. That doesn’t mean it’s a good idea.
