Neither of those molecules makes hair stronger such that it doesn’t fall out.
At best they provide a coating that makes the comb or brush slip through the hair more easily. This reduces the chances of the hair breaking and coming out.
The silicone will provide slightly better slip than the Polyquaternium-6.

@ngarayeva001 - This is why I contend that everything is natural. And this will be true until someone can prove the supernatural exists.

That depends on what you mean by “better”. Better at what?
The aminopropyltriethoxysilane is a silicone which will have better feel, slip and shine.

I always imagine little snail ranches and worker with tiny hands who have to milk them daily. I wonder how they collect this material.

@Margreat - I didn’t mean to come off sounding snarky but having been in the cosmetics business for a few decades, I’m a bit jaded when it comes to claims about most ingredients. I’m not cynical as I do believe there are things that have benefits (like surfactants) but I’m swayed by evidence, not anecdote.
The veterinarian who wrote the book may have researched the subject, but more likely was passing on information she heard somewhere along the way or read in some book or marketing material. Also, even really smart people can believe erroneous things.
I did a brief literature search and stumbled on this paper.
https://www.dropbox.com/s/k9rh5nmwaumn69p/aloe-research.pdf?dl=0In it the authors specifically examined the antibacterial effectiveness of Aloe Vera. They conclude that under their test conditions Aloe Vera has an antibacterial effect against some strains of bacteria but no effectiveness against other bacteria.” So, it’s not incorrect to say Aloe has an antibacterial effect, but it is not broadly effective against all bacteria.
Also, the study was done using 100% aloe in petri dishes. It wasn’t incorporated into a shampoo system to look for an effect.More importantly, the idea that you need to add antibacterial compounds to a detergent system is just mistaken. The FDA recently came out to say that there is no additional benefit gained by adding antibacterial agents to detergent systems. (https://www.fda.gov/ForConsumers/ConsumerUpdates/ucm378393.htm)
So even if you believe Aloe has antibacterial properties, there is no proven benefit to adding it to a shampoo system.
As far as Oatmeal goes, there is some research done on this too. For example this paper…https://www.dropbox.com/s/4uij9isak51jejz/oatmeal-itching.pdf?dl=0
…found that burn patients who received a parrafin treatment with colloidal oatmeal reported less itching. So, it’s reasonable to hypothesize that oatmeal is anti-itch. However, going from a topical parrafin treatment to a rinse off shampoo is a gigantic leap! And since oatmeal is water soluble it is very likely to simply get washed away and go down the drain.
This is why we say these are in there for claims purposes. There is no scientific evidence demonstrating putting aloe & oatmeal in a dog shampoo will have any noticeable effect.

@MarkBroussard -
lol! -
Wouldn’t a simpler formula be…
Water
Decyl Glucoside
Preservative
Water-soluble Natural Fragrance (www.carrubba.com)
Xanthan Gum
What noticeable benefits would be gotten from Aloe & Oatmeal extract? -
Did you check Google? There are lots of dog shampoo bars. For example…

@Microformulation - I was just wondering what plant could I grow to get Polyquaternium-10.

Try adding the extract into the water as the second ingredient. Then see which ingredient it is not compatible with.
What type of mixer are you using? If you are using a hand mixer then I would suggest you get a proper, center stir mixer to prevent foaming.
See this discussion for the proper equipment to use.

This is the nature of natural fragrances. If you want something to last for a longer time, you need something synthetic.

My formulation training is in cosmetic products so I don’t know the ins and outs of making a dish detergent product. However, something that works as a shampoo will technically work as a dish detergent but the amount & type of foam you get will probably be wrong. Cocamide MEA will rinse off fine so I don’t see a problem using it.
Phenoxyethanol may be fine enough but above a pH of 5.0 Sodium Benzoate isn’t going to have much effect. Personally, I’d use DMDM Hydantoin.

What are you making?

What type of product do you want to make? Shampoo, conditioner, styling product, other?

Fragrances are already safe for skin. When things are advertised as “skin safe” that is just a marketing gimmick that doesn’t mean anything new.
It’s like saying “wet water” instead of just “water”
-
Well, you’re going to have to tell us what the brand is and give a link to the ingredient list. Otherwise, we’ve given the best answers we’ve got.
-
The chelators actually interact with the microbe’s cell membrane and disrupt it which weakens the microbe and makes it more prone to being killed by the preservative.
-
I should point out this article is a little out of date. Unilever no longer owns VO5
-
Chelators are not used simply for hard water. They are also used to help improve the performance of your preservative system. There is no good reason not to use one.
-
You’ll need to provide more information about your formula to get any good answers. Ethanol does not need to be neutralized.
-
No. You can’t call hand wash anti bacterial according to the FDA.

@Gunther - Yes. It doesn’t evaporate immediately. It evaporates a bit slower than water.

That might work although you’ll probably have to heat the main batch up to ~70C to break the emulsion and reform it . You’ll also have to re-add some preservative and fragrance. But it really depends on what else is in your formula.
