I’m in US EST, for us BASF is distributed by IMCD. But @klangridge makes a good point

Everything people have said so far I agree with, but you asked about different forms of vitamin C. 4% ascorbic acid will likely cause you a lot of stability issues, and there are some papers that claim it can’t have all the miraculous effects if the pH is too high- and in your formula it would be. SAP /MAP are less studied, the problem you might see with them is they are salts which are typically problematic to emulsion stability.
Fragrances can contain common allergens, but that doesn’t mean they are always irritating. There are also suppliers (ex Carruba https://carrubba.com/) who can provide ‘aromatic extracts’. They are not true fragrances but they are blends of extracts that can impart smell

Lightening is not going to happen overnight- how long have you used the product for? Also what form of vitamin C are you using?

Where did you pull that quote from if you don’t mind me asking?

Unless you do a private label sunscreen or make *very* small changes (like scent or adding ‘actives’ below 1%) to an existing base, this will get extremely expensive- in the US because sunscreen is a drug there is more rigorous testing and you can expect to pay ~30-50,000 for development at most places

What kind of products- creams/lotions, haircare? Packaged in tubes or bottles jars? Every company has their strengths and core competencies , your best fit will probably require some searching.
What kind of order size are you looking to do? This is probably the first important question because most CMs have a minimum order requirement.There is a whole post where people list their various kinds of formulating services, that could be a good starting place

If it’s a retinol product, your pH will likely be a little high to use sodium benzoate/potassium sorbate- their efficacy drops off significantly the higher pH gets. At pH 6+ they are useless
-
Chempoint has made a page promoting their thickeners for sanitizers , maybe something in here would work
-
My understanding is tocopheryl acetate has no antioxidant activity unless you manage to hydrolyse the acetate, which can reportedly happen in vivo but I have no evidence of that happening in bottle to extend product shelf -life.

I’d recommend trying to neutralize before adding alcohol. You’ve got a high amount of carbomer, it really shouldn’t need to be over 1%. 980 is also not very tolerant of electrolytes, which your aloe juice is full of. If you are able to get Carbopol ultrez 21 or 20 that should help. Hydrate the carbomer totally by itself first, then adding in glycerin/aloe/what have you. You’ll be able to see if the amount of aloe you want to add breaks the gel right away so you know to adjust your amount.
Also, your alcohol level is too high to use NaOH as a pH adjuster, try TEA if possible or cut your alcohol. This document has lots of insights even though it’s for sanitizers with higher alcohol content.
-
The first thing I would look at is if your level of IPA can dissolve all of those actives just by itself. I also attached this guideline in case it helps. If it is separating, is it after neutralization? The large amount of aloe vera juice is going to interfere with your carbomer, you should cut that down significantly.
What is your order of addition? That’s also going to be key here.

I don’t think emulsifiers/ fatty alcohols will be able to impact greasiness as effectively as adding starch, clay, or some other filler.

Does anyone have a source on bentonite as an irritant? The CIR report from 2016 didn’t indicate any dermal irritation or sensitization and CIR is usually my go-to for questionable materials

Nice! just checking because the outer leaf is on prop 65

Just out of curiousity, @PeaceLoveNaturals when you blend the aloe do you keep the skin or just the inner ‘goop’

https://en.wikipedia.org/wiki/Sodium_hypochlorite
^that’s their ~star~ ingredient. That website doesn’t look very technical to be honest -
sodium polyacrylate and carbomer are very sensitive to electrolytes/charges, I have seen issues with both these products holding large amounts of ascorbic acid. That’s all I can say without knowing more.
Vitamin C (L-ascorbic acid) in a water base is going to have horrible stability, i wouldn’t recommend it to even a professional. If you want to use it within a day or two of making it sure but otherwise you’ll waste your money/time

See personally I don’t like Olivem because there’s usually a bit of soaping when I work with it. Most people who are using Olivem for the ~natural~ angle won’t add a silicone which would alleviate the issue.
-
Not surprised at all when you mentioned the ingredients- this formula has been around forever. we have our own version as I suspect many companies do.
The tightening effect is coming from Sodium Silicate aka Liquid glass. When it dries it tightens and also creates the rough feeling and you may see some residue if it dries out too much. As great as the instant results are, sodium silicate has an extremely high pH so please be careful especially since it goes in the eye area. If you do want to make it yourself you have to be aware of that and you’ll want to check wherever you buy it from provides a good CoA (Certificate of Analysis) as sodium silicates are used for lots on industrial purposes and those grades may have more/harsher impurities.
Feel free to message me and I can give you a formula close to our own, I don’t know it if will have the exact properties you like but all these instant wrinkle formulas are just variations of another.

https://online.personalcarecouncil.org/ctfa-static/online/lists/cir-pdfs/pr310.pdf < Here is the safety report for urea. This article is long but you don’t need to read all of it.
The only major safety concern I can think of is the fact urea is a good penetration enhancer, so be careful what else you mix it with. I don’t see a problem with a ‘urea toner’ , and it’s easier to start simple and work your way up- maybe you just add a gum to thicken the toner for easier application before you tackle an emulsion with it.
-
What kind of lotion/actives will you have- how much oil content and are you going to use hot or cold process? Every emulsifier has strengths depending on the environment
BTMS is cationic and common for conditioners- it works well for hair but on skin it might not feel as smooth and spread as nicely
-
1) Yeah emulsifiers are there to help the essential oils stay distributed throughout product.
2) yes- epsom salt won’t affect pH enough to put in in a low-risk scenario. And for a fun read, this paper shows that bacterial growth can occur even with high amounts of magnesium sulfate (as we would find on mars)

They have a formulation for a spray, SDS doesn’t have much information on toxicological inhalation effects.

The first document (SGS) is a little old (2014) but says Malaysia and Singapore are also under ASEAN.
“Cosmetics and personal care products in Hong Kong are governed by Chapter 456 of the Consumer Goods Safety Ordinance” . This article is also from 2014, their definitions seems loose but focus on proving safety/quality by adopting methods like USA GMP or following EU directives.
Another link I found helpful: https://cleanbeautyasia.com/cosmetics-regulations-in-asia
Just my two cents, but in the end you should think about what costs more- paying a regulatory service now or getting hit with warnings,fines,product recalls, maybe even lawsuits or other legal action because you misread another countries regulatory requirements.

@Rizbaig oil based gels have been mentioned on here in other discussions, try searching oil gel to see what ingredients you can use because carbopol will not work
