They haven’t been accused of causing breast cancer in people. Nothing causes people to turn on an ingredient like cancer & breast cancer specifically.
To be fair, lots of people absolutely despise Isothiazolinones @Belassi
-
Yeah, you only need to use like 0.02%
-
Cosmetics are not meant to be edible.
-
@ngarayeva001 - yes, most big brands have customized fragrances that no one else is able to buy.

What papers have convinced you of its effectiveness in topical treatments? What are you hoping the Superoxide Dismutase is going to do?
This isn’t a trivial point. If you’re going to use an ingredient in a product you should be able to show that it is doing something. In that way you can prove whether your storage method is suitable.
If you can’t tell a difference in your formula with the ingredient included or not or a deactivated version included then it doesn’t matter how you store it.

What are you hoping the Superoxide Dismutase is going to do? What’s the application? If it is just a claims ingredient, not expected to do much, just reconstitute it in water. It’s soluble.

When I worked at a large company, we bought it for ~$15 a pound. Of course, that was 20 years ago but the prices you list still seem a bit high.

I agree that most of formulating is learned on the job. I have a degree in chemistry and learned next to nothing about formulating cosmetics in college.
Yeah, I think the objectionable thing is claiming an expertise / credit for something that wasn’t earned.
I do wonder what the company did to annoy someone so much that they wrote a whole article about it.
-
What do you want these ingredients to do in the formula?
-
Hmm. I suppose you could add more oil to the system to overwhelm the emulsifying ability of the emulsifier.
-
Salt (NaCl) will usually break an emulsion.
-
Yes

@Belassi - Drugs are as drugs are claimed. No drug claims, no drug. Of course, you have to still be able to prove your product is safe.

This is not even close to a proper ingredient list. Words like “organic”, “infusion”, and “wildcrafted” have no place in an ingredient list. These are marketing terms that belong in advertising copy, not an ingredient list!
As far as mixing ingredients together, sure you can mix them together. That doesn’t mean it will remain stable or effect (it won’t). But consumers probably can’t tell the difference so there won’t be much negative impact on sales.

@mikethair - I was just stating my opinion about soap versus synthetic detergents. I like the modern detergents better than soap. I also think that if someone is reporting irritation from soap, then they would get better results from the modern detergents.
But you are living proof that there is a customer base that wants soap and likes the way it cleans their skin. Clearly, a soap can be made in a way that customers like the way it leaves their skin feeling.

This formula is a classic soap-based mixture. It’s similar to this
https://www.dropbox.com/s/ao2jjn3f2widsmk/soap-based-cleanser-formula.pdf?dl=0
The pH of this formula is 9-10 so your formula seems right in range with that (maybe a little high).
I think the irritation just means you don’t have enough secondary surfactants in there to offset the irritation of the soap. The Ponds formula has Glycol Distearate, Decyl Glucoside & Glyceryl stearate to reduce irritation. It also has a low amount of water.
@ngarayeva001 - Yes, I doubt the salicylic acid is having much effect. It could be first dissolved in the water and tied up in micelles which shield it from the KOH, but it’s probably just a marketing ingredient.
-
No, preservatives in formulas are not adequate to be antibacterial on the surface of skin. You can’t simply increase the level of the preservative either. There are specific regulations as to what can be used as an antibacterial agent.
-
Just to clarify, Cetearyl alcohol is a blend of Cetyl and Stearyl alcohol. not Stearic acid.
-
Have you seen a conflict? Is your preservative system working? What did your tests show?
-
Depends on what you use but pH 12 - 14
-
What regulations are you trying to meet? What country?
-
I’d say the problem is using old technology like soap when you could be using better technology like less harsh surfactants..

1. If you want to make 100kg, just put a kg after the number given in the formula. Propylene glycol 4.00 means 4.00 kg of propylene glycol.
2. Yes, you can try the same amount of CaOH as NaOH but you might need to make adjustments to the formula. You have to make it and figure it out.
3. PQ6 is a conditioning agent. So, you can find another conditioning agent or just not use one. You have to make the product and find out the answer.
4. You have to make the formula. It’s a starting formula that may or may not work for you. I can’t answer your questions because without having the raw materials that you are going to use, I don’t know whether it will work for you.
The formula will have a high pH so you may not need a preservative but you have to test it. Your manufacturing conditions might be such that you should use a preservative. The PEG 75 Lanolin and Cetearyl alcohol work as the emulsion system. I don’t know if you will need a more robust emulsion system. You have to make the formula to find out.
Cosmetic formulating is not something you can do by reading words on a computer screen or even in a book. You have to actually go out and get the ingredients and mix them together and see what you get. I’ve given you a formula that has worked for some people. I don’t know if it will work for you. You just have to experiment.

Cetyl alcohol is not an emulsifier. While it does have an OH group which can make it compatible with polar molecules, this is not enough to make it water soluble. Since it has no water solubility, it is not an emulsifier & the HLB value is a required HLB to get it to emulsify in the system. However, it is a co-emulsifier because when it is in an emulsions, its tails align with the oil groups and the OH aligns with water.
The equation to calculate HLB only applies to emulsifiers.

2 years! lol. The most likely cause is Entropy. Most formulators are happy with emulsions that last 1 year.
