Is this your product? The ingredients on the label don’t match your ingredients list. Why are the ingredients listed by the the Trade Name on the label?
How was the sample stored? I have seen this sort of separation when samples are stored at elevated temperatures.

Perhaps something like Ethylhexylglycerin (Sensivia SC) would be a better option than Zinc ricinoleate. It is multifunctional with deodorant and emollient properties.
-
The Euperlan Pearlescents require both sufficient viscosity and density to remain stable (Stoke’s Law). It does not look like your formulation would meet these requirements.
-
Try decreasing your CAPB as others have suggested and replace with SCI.
I would also caution using that much SLSa as some people are sensitive to it especially at high levels. If it is for personal use then adjust to your preference. Replace with more SCI.
If you are using this in combination with a conditioner bar you could also reduce the oils.

This previous discussion about this product may be of use.
As may this information about cold creams

You could try adding an amine oxide surfactant and / or a non-ionic surfactant (e.g. alcohol ethoxylate or alkyl glucoside).
There are lots of dishwashing formualtions on UL prospector that you could use to compare your formulation.
Hope this helps

What is your preservative? Is it active at the pH of your carbomer?
Is there any change in pH or odor?

Zinc oxide is an allowed mineral ingredient in COSMOS Organic and Natural Standard but it cannot be counted towards the organic content (because it is not organic).
-
This is not a correct INCI ingredient listing. Words like powder, liquid and crystals are not used in ingredient list.
What is cucumber? Did they just add an entire cucumber
Does it smell like nail polish remover? If the ethyl acetate was that high in the ingredients it would have a very strong odor.
I would not use this product. It is not a “professional” product.

I wouldn’t trust this ingredients list.
They use Leucidal as a preservative which is at best a poor preservative. The recommended usage of this “preservative” is 2 to 4 % so it should not be last in the ingredients list.
I think you can safely assume that this list is inaccurate.
They have likely left out some preservatives and chelating agents along with water to make it sound more “natural”.
If you tried to make this product based on this ingredients list it would likely be a big jar of mould and bacteria in a very short amount of time.
I have also seen people claim they used aloe vera “juice” but in reality it was just a small amount of aloe vera extract dissolved in water (a reconstituted juice?).
Happy learning!

Have you tried it without HEC? Is the HEC added for “cling” on the dashboard surface or for another reason?
You could also try different spray heads on your bottle.

The amount of fragrance and essential oil is very high. Usually the combined total of fragrance and essential oil would be around 0.5% but maybe up to 1% depending on the fragrance/essential oil combination used.
Unless it is a particularly difficult to solubilise fragrance(or essential oil) you usually don’t need an additional solubiliser (i.e. Polysorbate 20) because the other surfactants solubilise the fragrance.
Try reducing the fragrance/essential oil and remove or lower the polysorbate 20. Remove or significantly reduce the glycerin. Doing the above will help to thicken the product and you should be able to reduce or remove the xanthan gum. Sodium coco sulfate should thicken with salt and this would give better sensorials than high amounts of xanthan gum.
Hope this helps

What is the other ~80% of the formula?
You could try changing LABSA to the sodium salt (Sodium docdecylbenzene sulfonate powder).
-
I suggest removing the Euperlan because it will not work in a low viscosity formula. If you want an opaque product look at an acrylate opacifier instead.

Electrolytes and salts can cause shampoo bars to become soft and mushy. Try your bar without any extracts or salicylic acid.

Don’t be dissuaded from using synthetic fragrances just because some people prefer essential oils. Synthetic fragrances are safe if used in accordance to the standards set out by IFRA (International Fragrance Association). Essential oils usage is also subject to the same IFRA standards.
If you are trying to target a natural market then your market may prefer essential oils but this is a marketing preference not a safety one.

Depending on the quality of your fragrance 5% will be too much. Start around 0.5% and increase if needed.
You could decrease the Vitamin E also. More information here https://personalcarescience.com.au/Workshops/cosmeticscienceworkshops-2110/Blog-4192/VitaminEinformulas:antioxidantversusprooxid-7472/
Just start by making small samples 50g or 100g so that you don’t waste too much material.

As I said above it is more difficult not impossible to get good foaming without sulfate.
FYI - Dr Bronner uses sulfate surfactants in their multipurpose cleaning product. It is recommended for washing dishes among other things.

Search websites like UL Prospector for starting formulations. Also look at suppliers websites (e.g. Stepan, Colonial Chem etc). This will give you a good idea of what percentage of surfactants etc you will need and some basic manufacturing instructions.
Without sulfates it will be much more difficult to get good foaming (not impossible just more difficult). Are sulfonates acceptable?

This sounds like there could be contamination in you filling machine. Has it been thoroughly cleaned between products.
If this is happening in less than 12 hours it is probably not microbial contamination.

No sorry.

Thanks for replying. I will put both lots of information together and see how we go.

That is my understanding. Zinc oxide is not organic. It might be “natural” but not organic.
On page 15 of the standard it gives the following information.
6.2.2 Minerals and ingredients of mineral origin
Minerals and ingredients of mineral origin cannot be calculated as organic.Hope this helps.

This review of preservatives from Making Skin care is a good start for looking at preservatives.
For lotions and creams I would probably start with PE9010 with sodium benzoate. If you have the ability to properly test your products (preservative efficacy testing) then you can try some of the other preservatives but pay careful attention to pH and use the hurdle approach for best results.
