It should work fine, EDTA has better solubility with increasing pH. Just test and see if it dissolves.
Phytic acid is also a chelator and it will keep your pH very low. I prefer it because it’s more biodegradable than EDTA -
Not enough information to help you. What’s the formula?
Equipment could be the issue but no one can help without more context -
There are different grades of xanthan gum, they all thicken differently. If you can get spec/ or a coa for something you can purchase look for a test on viscosity. Usually there will at least be a percentage they put in solution and you can see what result they got.
Even though there is variation, for most grades I’d use anywhere from 0.2-1.0 %

Can you tell us more about your brand’s positioning? who are you targeting, what will make your brand unique?

From an actual supplier or a repacker?
Trade names:- Dermofeel BGC (Dr. Straetmans GmbH)
- Miglyol 8810 (Cremer Oleo)

You don’t really need the Sodium Benzoate do you? It’s activity diminishes drastically as pH rises, I think above 5.5 it is functionally useless. I don’t know if that’s interacting with HEC but might as well take it out.

This topic has been covered, here are some posts about it with all kinds of suggestions. What you use will depend on polarity of your oils, what you have available, if you want to heat or not etc

I have ultimate and aerosil 200 (silica). I eyeballed and ended up with ~ 4% silica and it made a pretty stiff gel so I’d say yes it will work fine!

The nice thing about percents is if it worked small-scale in theory it would work large-scale. Did you test stability on your smaller batches? The processing equipment will just have to mimic whatever worked for you before.

that’s not how I read it, the first link explicitly says for the EU you still need to comply with the regulation 1223/2009 even if you ship directly from your country to the consumer.
That first article tells you what you should do, as to whether or not you will actually be held to those standards is a different question.

Ecommerce is weird, if you want to be by the book you could consult a regulatory office. Here are some links I found:

You would have to follow the standard OTC rules if you want to deviate from the temporary compounding. So registration, manufacturing in FDA registered facility, testing, etc.

Well that’s what I get for trusting google translate
my spanish is very rough but I was keen to try . @letsalcido lol thank you for clarifying.@Econatural which sharomix? there are several.

Puede permitir si quiere, pero en futuro incluya un preservativo aun la es anhidra. La probaria de nuevo porque usted resultados estan aumentando (lo parece).
e.j Symdiol 68 (1,2 Hexandiol y Caprylyl Glycol)
Google translate:
You can allow if you want, but in the future include a condom even if it is anhydrous. I would try it again because you results are increasing (it seems). -
Clarity depends in part on the kind of carbomer you have (940, 980)
The lemon EO will also affect clarity- how much is there? you are better off adding it into the IPA -
You should list the INCI names or at least the full trade name. jeen has several jeecide products in their line. You could also just email them and ask for processing tips

Prop 65 is a never-ending headache, literally just talking about a similar issue yesterday and here’s what we found

Pretty sure dimethicone with cationic guar goes into 2 in 1 shampoos? https://patents.google.com/patent/WO1999032079A1/en

Majman said:I’ve heard of corbol or corpol, not sure, lease help
I think you mean carbopol, which won’t help for an oil based product. Search the forum for ‘oil gellant’ or ‘oil gel’ and you’ll see there are several materials that could help, depends on what you can get your hands on. Not all oils are the same, avocado might not be the best for dissolving salicylic. You can cut down or change the base oil
-
1% tocopherol or tocopheryl acetate? Tocopheryl acetate provides no benefit if you’re looking for antioxidant potential, and 1% tocopherol is likely overkill. So drop it completely if the acetate, maybe cut in half if tocopherol.
Polysorbate 80 will definitely be sticky, peg 40 HCO with some butylene glycol might not be as bad.
the 10% SAP will likely also feel sticky on skin while drying as well though, our 20% SAP serum does.

You can’t dissolve it, you could suspend it

If you are using 0.05% of the vitamin C derivative I wouldn’t initially suspect that. Licorice extract can brown over time.
To make sure I understand, how old is the formula in question? Do you mean products that have sat in a warehouse for 2 years are browning? Or that a new batch put in this summer has browned? Storing at 40 C or even just inconsistent temperatures you can expect discoloration, possibly separation.
I haven’t used that specific amitose, I used a different kind in the series
-
Uh I imagine it would depend on concentration of each and the particular surfactants’ affinities. I don’t know any specific literature studying how fast that occurs
-
Polymeric emulsifiers like Sepimax Zen or carbomer can still hold the product together, xanthan gum not so much. Your feel will be completely different from the benchmark product. You’ll lose the emolliency and balance that the fatty acids provided.

I see it being used as a humectant in BASF material
AMC Advanced Moisture Complex NP
with trehalose, sodium PCA, hexylene glycol, polyquat 51… so maybe any of those would be a safe substitute
