Hey @RDchemist15, thank you! I will try it
-
Or you can swab it. As you would do on your tables, equipment etc …
I believe some tests you can do even yourself. If you buy Agar plates, sterile swaps, nutrient liquid and incubator. You just need to know how to count colonies, what to look for etc .. Just an idea Of course it is better to send it off to more qualified companies.
-
Yep, gums or polymers.
-
Thank you guys. I was really hoping there is something I can do to make EGDS work. I don’t have any other use for it
I don’t have a lot of it, but don’t want to just throw it away. @ketchito hmm, ok, will try to cool it down faster.
-
I think everyone should say a huge THANK YOU for Mark’s time and for sharing his amazing knowledge! We all can learn something new and we do (at least I do) very much appreciate it. So thank you @MarkBroussard

1. Supplier should usually provide nice and clean packaging. If not, I would return it. Cleaning the packaging is not a good thing.
2. You should also conduct some microbial testing on a few packaging.
3. Your preservative system should be strong enough to avoid any issues.
(that is why you’re usually sending product in its original packaging for PET).
4. If you are making things at home (small batches), you can spray it with a rubbing alcohol.You usually do not need things to be sterilized. Sanitized? Yes.
Clean air and GMP is also important. -
Caprylyl/Capryl Glucoside which if I remember correctly is also natural.
I think also Taurates and possibly Isethionates should be strong enough to solubilize small amount of lipid.
-
Do I need an emulsifier? If so, which is appropriate? - I would say no, Sepimax ZEN is your emulsifier at this input. You can lower it and add some other non-ionic emulsifier to make it more creamy (less gelly). However only stability testing will answer your question.
Is it possible to make a transparent gel which contains oil phase? I would say no. Once you introduce lipid (not solubilised) it will turn milky.
What can I do to achieve my intended result? Remove oil or solubilise it.

Those mentioned ingredients are fine and safe if used within their regulatory limits and as meant to. That is all we can tell you. You would need to provide full formula (and method) for us to review it and correct it if needed.
Even though skin itself does not have pH, it likes pH around 4.5 - 5.5. So you are safe to formulate to that levels. (Unless you are using actives/preservative that require specific pH, then you formulate to those needs)
Hope that helps.
-
Niacinamide is really stable ingredient. It tolerates lower pH - best to use between pH 3.5 - 7.5. (It has been mentioned couple of times on this forum).
To get its acid form, you would require quite high pressure and temperature (and low pH). Which won’t happen during your product manufacture.
-
Yeah, tetrasodium glutamate diacetate is a good chelator. And @MarkBroussard uses it. Typical usage rate is 0.2 to 0.3%.
But as mentioned by Phil, NaEDTA’s are good option too.
-
I think above 1000 kDa it is considered high molecular, but again, as Abdullah said, the higher the better (for gelling). I would say 1% is a decent (high) input and it probably does form a thicker layer that eventually dries thus the tightening.
Try to source higher MW and see how it goes.Keep in mind, we do not know what is “thick enough” for you.
You are maybe expecting too much from it? -
You dilute them by adding them into the water.
So you are going to use 14.3% of lactic acid to get 10% solution and 4.05% Glycolic acid to get 4% solution. -
Well, that depends. In hair masks for very dry and damaged hair it is really beneficial. As it draws moisture to the porous and damaged/dry hair. Same as conditioner (it also prevents drying of the product), but it helps retain some of the moisture so the hair don’t get super dry after - Plus it fights frizziness.
In my (humble) opinion, it is good to have a good humectant in hair products.
And @Camel, yeah, 2% should be fine. Try it out and see.
-
Lol @ketchito, I am reading this at little bit after 6 am and … it is a deep thought
… -
I guess the water lifts hair cuticles, therefore the product can “get in” easier.
-
1. Remove HEC and use cationic guar (hydroxypropyltrimonium chloride).
+ Add high HLB non-ionic emulsifier. It will build viscosity and improve wash off.
2. I think 1-2% is fine.
3. Yep, Glycerin is beneficial. Use Glycerin instead of Propanediol. It’s way cheaper and I dare to say way more effective. -
Yeah, I am with @ketchito.
Polysorbates are most like superfatting agents/solubilizers. So share the purpose of the product and we can help you.None of those are salt responsive, so they won’t think with salt. You will need a gum/polymer to thicken it. (HEC did not work in my surfactants at all. Always separated.)
-
Thanks for the update Abdullah
good to hear! -
It looks like foam to me too.
Heat it to 35 - 40°C. As you would do your stability testing. -
I probably started as maximalist too. I remember buying my first CoQ10 and some proteins and Niacinamide and other stuff and thinking everything together will create the ultimate serum/cream. It turned into ugly snot and I soon realized the less is usually better.
At the moment, I am minimalist with extras. Have formula with necessary ingredients and only improving it by a hero ingredient/s and marketing ingredient. Although I do feel like I am cheating my customers. So I am not really crazy about my product story. And thanks to you Perry, many ingredients (Panthenol etc) I am using at low inputs and letting other (well proven) ingredients work the wonders
-
If you are using cationic system, 4.0 - 4.5 is usually the best range to go. And it is safe.
And all cosmetic ingredients that are allowed in cosmetics products are considered safe if used within their regulatory limits and used as meant to.
-
Yep, I am with the boys. Ingredients differ significantly.
That is also why you should use Trade names (and/or supplier’s name) on your formula. So manufacture gets the exact material you have prepared your samples with. -
Yep, try it.
I would measure the pH after adding the aloe juice. The one I had was really acidic and brought my pH to around 4. Try to have it close to neutral before adding cationic guar gum, so it has time to be properly dispersed in the water phase. This is my thinking.Try it and let us know.

It really depends what you want the toner to do.
If it’s for hydration, you could use hyaluronic acid. If it’s for brightening, use the mentioned Niacinamide. If it’s for exfoliation, you could use some AHA … It really depends.Typical usage of humectants is 1 - 10%. But again, it depends.
