Shear is very emulsion dependent.
I only do lab-scale….so I shear for 2 minutes at elevated temps, before lamellar structures are formed.
I stir the entire time until pouring below 35 C.
Some emulsifiers greatly benefit from one last kiss of shear below 40C. I know PCP is one that likes a late kiss of shear.
So, question is essentially impossible to answer…without more details.

Umh…..every single cosmetic has the formula listed on the packaging. (LOI)

Likely the Mg Chloride. Delete it…it is a placebo ingredient anyway. If you need it for claim, include it at .01%
If that doesn’t fix it…do a knockout starting with the bottom one…followed by the aloe.
Even HA is a well-known irritant if the dalton size is small enough.
You did not list rates…which is certainly not helpful at all. Even Niacinamide becomes an irritant at some point.
Also list pH if you want educated responses vs guesses.

Overall …. looks like something a beginner tossed together to try and ring as many ‘claim’ bells as possible. A plethora of irritants and allergens. Look for something efficacious to model!
Appears to be one of those brands…. that only list…. what they think you want to see. 🙁

MemberApril 23, 2025 at 4:03 pm in reply to: Want to exchange between Mg(OH)₂ and TEC in deodorantI have sensitive skin… Mag or BS would likely send me to the ER.
TEC is NOT low pH…it has NO pH.
TEC is used IN a low pH system. These systems are MUCH MORE difficult to make well….hence the indie brands have dropped back to beginner level concepts without regard to the users skin.
If you simply drop high pH items and sub in TEC….you will be sorely disappointed. It is a tiny piece to a big puzzle.
If you think the Indie brands have the best and brightest and most experienced cosmetic chemists on the payroll….maybe think again.
Good Luck.

MemberApril 23, 2025 at 4:13 pm in reply to: Want to exchange between Mg(OH)₂ and TEC in deodorantThe mag used it deo…is traditionally a higher pH than the BS used. Scratch your head for a minute…its allowed. So why is BS exponentially more irritating than the mag? Solubility. BS creates a very rapid….for lack of a better term…. explosion of high pH. Mag has poor solubility in water (water is introduced by skin and sweat). Hence, for lack of a better term…. it is more like a ‘timed release’ elevation and maintenance of high pH. See the difference?
If you look at where microbes (the source of odor) thrive….in general, the range is 5-8 (of course there are outliers). Hence it is easiest to make a deo….either above or below that range. That is why you see the two systems on the market.
When we use soap on our skin….it is high pH. Hence we ‘wash it off’ after use. So, leaving something in place, that is high pH…is profoundly different….than using soap.

MemberApril 23, 2025 at 3:58 pm in reply to: Can Someone explain how the water is incorporated into this stick product?As mentioned,…it is below the 1% line. I suspect it came along for the ride with another ingredient…and was not directly added as an ingredient. Might even have come with the aloe….but there are other possibilities as well.

MemberApril 21, 2025 at 6:18 pm in reply to: ACV is one of few products that dont irritate my skin but can it benefit phSearch the contents of your skin’s NMF (Natural Moisturizing Factor). This is what YOUR SKIN MAKES…to keep itself moisturized. The list you search should come back something like this:
1) Free amino acid ≈ 40%
2) Various ions (chloride, sodium, calcium) ≈ 18.5%
3) PCA ≈ 12%
4) Lactic Acid/Lactates ≈ 12%
5) Sugars, Inorganic acid, peptides ≈ 8.5%
6) Urea ≈ 7%
7) Ammonia, Uric acid, glucosamines, creatinine ≈ 1.5%
8 ) Citrate ≈ .5%
Look at line #4. Ingredients off this list….are generally well tolerated by skin….as they are things it naturally makes. Hence…I would throw my hat in the ring with adjusting pH with lactic acid.

MemberApril 21, 2025 at 6:11 pm in reply to: does anyone make cosmetic supplements for internal use?First I would remove the word ‘cosmetic’. That is one of the lower standards in industry. I would elevate to ‘food grade’ if I were going to ingest it.
A number of us take supplements that we hope for a positive outcome on our exteriors. The brilliant George Deckner once wrote a piece on this….let me get you the link.
I take: lutein & zeaxanthin and astaxanthin and Hyaluronic acid with collagen orally every day, with my skin in mind.

Humans are like snowflakes (in fact, some are SNOWFLAKES! ????). What that means….is there are no two alike. What bothers you…might not bother me…and Vise versa. So, you have asked a question that is difficult to answer, one that maybe you can only answer for and about yourself.
That being said, the EU has delineated the most common of the allergens contained in essential oils and fragrance ingredients, and even preservatives. With essential oils…it is rather simple to find a GC-MS…and determine how much of these allergens are contained in a specific EO. The only value that will have… is it will give you some insight on the increased or decreased likelihood of the entire population, having any type of sensitivity.
As we like to say….the poison is in the dosing. You can use some of these type ingredients….if you use it at low enough rates (EO’s / fragrances). Some people will not react…if you use many times too much….others will be intolerant to even the smallest amount. Typically, it is pretty difficult to make a cosmetic that the ENTIRE population will find suitable. Hence….you guessed it…. why there is more than one brand. ???? And why ‘unscented’ products are offered. This field extends well past fragrance…and can include about any possible ingredient in a formula.
Good Luck.
The attached link has the EU allergen list in the article. Just use that list…when you study the GC-MS of an essential oil. New allergen list - Cosmacon

Maybe consider a slightly different approach. What I read into your comments is…. “Two things are better than one.” Granted there can be some truth in that statement, but more likely that will lead to having redundant strengths, and redundant weaknesses. You have on the line (Dr Phil Geis) one of the world’s foremost experts in cosmetic preservation. Utilize this opportunity to garner the information you actually need. (Please know…there is nothing wrong with redundance! It should be strived for.)
Approach your questioning to Dr Geis more like this. I will start with a base of PE9010, which I know is proficient against Gram negative bacteria. Dr Geis…. What would you add (if anything) to shore up Gram positive? What would you add for the well-known weakness in the aspect of YMF?
Asking the right questions in life….is always what got me to the desired outcomes and results. ????
And please lose the ‘L’ brand. That is just embarrassing to see that mentioned on this forum.
I came across this nice little piece I had saved a while back from some book I have….forget which one (who know…might even be from Dr Geis’s book) :

Pure lies…. you forgot to mention preservation. ????
How many emulsions of small brand have you not seen, that did not even include an emulsifier.
They believe the FDA only has time to fry the big fish. ????
As they are selling to a ‘special’ clientele, they provide a special LOI. ????

MemberJune 22, 2025 at 5:40 pm in reply to: Methyl Glucose Sesquistearate and PEG-20 Methyl Glucose Sesquistearate pairing.Thank you. I will have to debate that. Not the concept….but the fact that I can never purchase the Evonik MOQ’s… but I can buy the Lubrizol pairing small MOQ at the Thai place.

MemberJune 20, 2025 at 1:43 pm in reply to: Methyl Glucose Sesquistearate and PEG-20 Methyl Glucose Sesquistearate pairing.Thank you.
Question…. Lubrizol’s Methyl Glucose Sesquistearate has an HLB of 6.6. Evonik makes a version that has an HLB of around 12.
Does the Evonik and Lubrizol version match up (make a good pairing)…as they do not have the HLB spread that the two Lubrizols would have. I suspect no….but maybe I am not seeing the big picture?
Aloha
(It happens that I found that I have a sample of the Evonik version, Tego Care PS … after an additional search.)

‘J’ is right of course on the charge…. as well, the higher MW HA’s are disruptive to emulsion formation, so timing is key. Your addition of your pre-hydrated mix of HA should be added post emulsification.
Always memba…. HA is typically a claim ingredient… so use less of it (way less)…. and then you won’t even notice the damage it is doing to the formula. Granted this is not a hair product….but this gives you an inside look at how HA is used in industry:
Best selling eye cream on Amazon….to which I even included the full formula. (You are welcome.) Sells 50,000 units a month. Take careful note of the vast amounts of HA they use.

Most doctors do not study this type of medicine….most of them learn to cut it out…and drug it out. If I come across a ‘Dr recommended’ cosmetic in my FB feed…it is likely with worst product on the market, and often times they attempt to preserve it with spoiled Korean food, which demonstrates they have no acumen in the field.
Where the error lies… just like in mommy blogger deodorant (find one that doesn’t have utterly gross coconut in it) is that they don’t distinguish between free lauric acid, and lauric acid bound in a triglyceride. Guess what…. makes a difference. Just like stearic acid in a butter, which is bound in a triglyceride….does NOT perform the same as free stearic acid. ????

MemberApril 24, 2025 at 7:13 pm in reply to: Want to exchange between Mg(OH)₂ and TEC in deodorantTEC and pH are just parts of a big puzzle. Hence, in and of themselves…you won’t achieve a product with more than a few hours of efficacy (akin to splashing lemon juice, vinegar etc…on your pits in the shower). (Your skin is trying to alter the pH, from the moment you apply.) You need antimicrobials. You have mentioned some. They will be the backbone of the project.
It is very difficult to make an anhydrous, low pH product. How are you as a laymen…gonna measure pH??? The pH can only be measured on the skin in that format…..after it combines with sweat and skin moisture. Lume has both a hydrous and anhydrous package….I suspect the anhydrous option took up 96% of their development time. How to take an acid in a dry format…and make it come out to just the right target pH….when applied to skin! Think about it.
If you don’t have extensive knowledge in the field, I’d probably stick with the very simplistic magnesium version. Essentially all Indie brands lack the knowledge, therefore flood that approach.

Pretty fascinating what you can come up with under the ‘fragrance’ banner. ????

Baking soda does only one thing. It raises pH. The irritation…is essentially a pH burn.

They are the most skin hostile ingredients in all of cosmetics. And just AWFUL for those with any skin maladies. Just a cacophony of irritants and allergens.
If you sell a product with these ingredients…. the least you can do is put the number for poison control on the product.
It is the only group of things put into cosmetics, that require being run through a toxicity screen before using. I think beginners don’t like that kind of language…so they have gotten creative with the name of the toxicity screen….and call it something laughable like…. EO Calculator. ????
