I would expect to see some variation from any botanical product due to difference between cultivation, season/location/climate of growing. You can get standardized portions of extracts but they will obviously focus on one or two major components.
When you say consistency what is different- color, smell, clarity?

Sodium Methyl Cocoyl Taurate has some nice creamy foam, you could also try HPMC -

You have to give more information, ideally ingredients with standard INCI names and percentages. Nobody can help you without more info

The company Symrise has a couple different ‘anti-irritation’ actives that show some promise. But like most supplier’s their data is self-published and not exactly rigorous. Not sure if they sell those to any repackers either

The pH would probably be high, but I wouldn’t store it for long term use without a preservative, especially if your water is not sterile to start.

LaraCare® A200 (INCI Galactoarabinan ) “LaraCare® A200 is a natural, mild, and water-soluble polysaccharide that enhances emulsion stability, reduces transepidermal water loss (TEWL), and provides moisture control in formulations. This product helps to improve appearance of skin’s superficial fine lines, impart film forming properties, and helps improve formulation uniformity which may ultimately enable SPF enhancement. It is approved by ECOCERT in ecological and organic certified cosmetics

This will show studies and give you some idea what percentages were not irritating when tested -

I would think anything that can maintain the proper temperature/humidity levels for the duration you need will work. I just don’t know if an egg incubator meets those requirements
also this is the post you are mentioning

Building off ketchito, you could swap those microspheres for Aerosil 200 (silica), unless your particle size is already less than 200 m^2/g

MemberSeptember 8, 2020 at 6:13 pm in reply to: WHICH INGREDIENTS REDUCE TACKINESS OF HUMECTANTS IN SERUM?it depends on everything already in your formula. Butylene glycol can help cut tackiness , starch, you could add a water-soluble silicone
-
you can also always try adding a starch to help with the stickyness, but too much will feel filmy. other than that @ngarayeva001 covered a lot of good suggestions

How do you know increased CO2 benefits skin? in what way?
You could get the same result with vinegar and baking soda, though I wouldn’t recommend putting that on the skin. I’ve worked with alginates, but I’m confused what your question is
-
I’m not a color cosmetic person, but maybe add silica (aerosil 200) to get the matte effect?
-
active surfactant:
you have 12% SCG, only 30% is active, so final is = 12*0.3.6%
same for CAPB it’s 2.4%if you are adding xanthan gum after surfactant that could be the issue. Add it in before predispersed in glycerin

https://www.fda.gov/cosmetics/cosmetics-labeling-regulations/cosmetics-labeling-guide#clgl9Definition:
Any processing aid added and removed or converted to a declared ingredient
or
Any ingredient of another ingredient or processing aid present at an insignificant level and having no technical or functional effectNeed not be declared
Incidental ingredients need not be declared on the label.
An incidental ingredient is defined in § 701.3(1) as:
1. A substance added during manufacture and removed from the cosmetic in accordance with good manufacturing practices before the cosmetic is packaged in finished form. Example: Filter aid.
2. A substance that is added during manufacture of a cosmetic, is converted to an ingredient declared on the label, and does not significantly increase the concentration of the declared ingredient. Example: Sodium hydroxide added to a sodium stearate and stearic acid-containing cosmetic.
3. A substance added to a cosmetic during manufacture for its technical effect in processing but present in the finished cosmetic at an insignificant level and not having any technical or functional effect in that cosmetic. Example: Defoaming agent.
4. A substance added to a cosmetic as a component of a cosmetic ingredient and having no technical or functional effect in the finished cosmetic. Example: Preservative of a raw material added to a cosmetic as an ingredient at a concentration which reduces the preservative to a level at which it is no longer effective.

Maybe kester wax k-60 P (polyhydroxystearic acid)?
-
Sugar or salt should work fine here just get the right particle size. The oil could go rancid but you have tocopherol to protect it. I don’t think the rancidity would affect stability but can’t say for sure without testing..
Never used naticide, you could try hydrolite 5 (pentylene glycol)?
-
You can look at the fatty acid/triglyceride profiles of those lipids to try and find substitutes. I’d say keep jojoba because its a liquid wax with pretty unique composition. Most of the others look like drier, fast absorbing oils
-
You’ve got plenty of options, probably best to get a blend to start that offers broad-spectrum coverage (yeast and mold as well as bacteria).
If you can test pH reliably (not pH strips) and keep your product below pH 5.5, then you can use additional sodium benzoate, potassium sorbate. Otherwise stick with something like phenonip or germabenIf you do not add an emulsifier your squalane will sit separate from your water phase.
