Of course there is also the question, why do you want to combine them? What do you hope to achieve by using both actives?

It you are using it in a cleanser then it just rinses down the drain. If you’re using it in a wipe on / wipe off product, then it goes into the wash cloth. Even if some is left behind, it eventually is sloughed off the face along with all the dead skin cells that you are always losing.

According to the USDA who would be the “organic” certifier, only things produced via agriculture can be labeled organic. Thus Zinc Oxide is not organic.
I looked into it a little and while Salt is not organic, if you use certain additives the USDA allows you to label “made with organic ingredients.” https://www.ams.usda.gov/sites/default/files/media/7%20Salt%20and%20Preservatives%20FINAL%20RGK%20V2.pdf
However, I didn’t find anything suggesting you could to the same with Zinc Oxide.

Don’t put that much glycerin in your formula. It kills your foam and can reduce the viscosity.
The Glucoside will also kill your viscosity. You don’t need it in your formula.

The color instability and white patina in your W/O foundation may stem from the interaction between TRIETHOXYCAPRYLYLSILANE-coated pigments and the EASYNOV emulsifier, leading to oxidation and color shifts. To address this, consider testing different pigment coatings, adjusting the pigment-to-emulsifier ratio, and incorporating antioxidants like tocopherols to prevent oxidation. The white residue might be due to emulsifier-pigment incompatibility, so optimizing the formula with compatible fillers or co-emulsifiers could help. Additionally, ensure batch-to-batch consistency by tightly controlling raw material sourcing and manufacturing processes.
But really, without knowing what is all in your formula it is hard to give a more specific answer.

I suspect there will be some lawsuits that reverse these decisions since the FDA is responsible, but if you’re a big company selling international formulas, you were probably avoiding formaldehyde donors already.
No, I doubt anyone would create a special formula just for Oregon and Washington. The chances of product being diverted to those states would be too great and there just isn’t a huge benefit. Replacing formaldehyde donors is not (yet) that big of a problem.

I would think using high HLB surfactants would be better for removing oil which is what you would want to do with makeup removers. Although, maybe you also want a blend of low HLB ones so they can more easily be removed.

You’re trying to mix water and oil without an emulsifier. That’s usually a problem.

Here is what they specifically claim…
3% Citric Acid
Our range formulated with Citric acid, acts from core to surface to deeply eliminate calcium overdose and help neutralise dullness and stiffness.
5% Glycine
Once excess calcium is removed, our products, formulated with glycine, are designed to strengthen the hair fibre’s internal structure. Reducing breakage, restoring hair strength, and leaving it beautifully shiny and supple.
———
I don’t think they mean “this formula has 3% citric acid or 5% Glycine”. They say “Our range formulated with Citric acid…”
They also say “…our products, formulated with glycine…” so again not referring to a specific formula.
So, I would guess that they are referring to the fact that they use a 3% Citric acid solution and a 5% Glycine solution. This seems misleading to me but I think we can safely conclude
No, they are not using 3% citric acid in their formula nor are they using 5% glycine.

Yeah, you’ll need to be more specific with your question.
-
Your understanding is correct.
Also, sure the buffer can be used in both emulsions and water-based products like toners and serums.
As for the amount to add and the timing:
- Quantity: The specific amount of Solution C to add will depend on your overall formulation and desired pH. Typically, you should start with small increments and measure the pH until you reach your target.
- Stage in the process: It is usually best to add the buffer solution during the aqueous phase preparation, before combining with the oil phase in emulsions or before adding any active ingredients in water-based products. This ensures a stable pH throughout the formulation process.
In truth, I don’t really understand the focus on “buffer systems”. It’s not really a thing that is given much attention in professional formulating.
How did you get interested in it?

To make it harder you would need to reduce the levels of Cocoa Butter and Shea butter. And increase the levels of the fatty acids. Of course, that might reduce the effectiveness on hair but that is the trade off you face. Now, if you incorporated a silicone…

I started work with a CM who (without saying anything to me) swapped out my working preservative system with one of the “natural” ones they liked to work with. Of course, the stability test failed. They just didn’t want to work with parabens. I found a new CM.

I agree with @ozgirl - 11% glycerin is way too much! You’re also getting more glycerin from your extracts and the Plantapon. You probably don’t need to add any glycerin but certainly reduce it to 1% or less.
You might try an acid different from citric acid. Try Lactic Acid maybe that might make a difference. If you don’t like Polysorbates, could you use something like Oleth-20? It’s not as well-known and it may help solubilize the essential oils.
-
I agree with @ketchito - use less than 1.5% even. Try 0.1% The ingredients won’t make any difference any way and are simply claims ingredients.

I would guess heating up the sample would accelerate degradation. Just put it in an oven for a while.

There is nothing in the ingredient list that would clean hair or create foam or preserve the product so you are most likely right. They just didn’t list the ingredients that are actually making it work. They say on the label “This is not a cosmetic” so they are admitting to not following cosmetic regulations. Therefore, you can only guess what is really in the product.

While COSMOS and other natural standards might allow Zinc Oxide to be called “natural” no one in industry is using “natural” Zinc Oxide. All of it is synthetically produced. The stuff that is mined is broken down then chemically oxidized (French process). Actually using natural zinc oxide would expose people to dangerous levels of heavy metals.

I think it’s difficult to even get a pure “Lauric acid”. Certainly when you get lauric acid in the cosmetic industry it is still a blend of C12, C14, C10 and residual others. It’s just that it has a higher level of C12 than something like lauryl glucoside. There just isn’t any great benefit to getting 100% pure Lauric acid in our industry.

I think your bubble problem is more a reflection of how you are making your batches rather than the formula itself. If you are using a homogenizer on a 300g batch, I doubt your able to get the head of the homogenizer to be completely submerged. So one strategy would be to make bigger batches.
-
You haven’t asked a question. You simply put “update” then gave some pictures and description.
If you want some assistance please summarize what the problem is and what further questions you want answered.
Honestly, there are dozens of discussions going on here. If you want a response you have to make it EASY to answer. You can’t expect people to go back and review the entire previous thread to figure out what you want to know now.
-
I would think to be safe you should keep the pH below 5.0 since Sorbic acid doesn’t work particularly well above 5
-
I would normally just dismiss it as that but this is from L’Oreal! They know how to make an ingredient list.
-
With just a tiny amount of water, you likely don’t need a preservative. I’d add one just to be safe but I doubt it is ncecssary.
