You need to provide more information including what other ingredients are in the product.
I am assuming that if they are going PEG-free that the product is also sulfate-free. Sulfate-free systems are more difficult to thicken than sulfate systems.

I am not sure what some of your ingredients are since you only give trade names.
You could try adding a builder (sodium citrate is commonly used but other chelants can also be used)
If your market accepts them, an optical brightener would help make white fabrics appear whiter.
You could also try increasing the concentration of your surfactants.
Have a look on UL Prospector or supplier websites for starting formulations to compare with your formulation.

How big is the batch you are making? Could this be a weighing error from only using very small amounts of dye?
If it is a UV light issue you can also look for PET packaging with UV filters incorporated into the PET.

Preservatives are often not required for anhydrous blends but honey is not anhydrous and you would be best to leave it out if you are only going to use oils and beeswax. FYI-Sweet almond and Rosehip are carrier oils (or emollients) and not essential oils.
If you add water (or water soluble ingredients) it is necessary to use a preservative. It is also necessary to use preservatives if your product will come into contact with water. The preservative you use will depend on the product type (e.g emulsion, surfactant blend) and pH.
Here is a good review of the common preservatives and their limitations.

You could try adding a defoamer/antifoam (silicone based) but it would probably be easier to just find a lower foaming surfactant instead.
If it is for personal use only you could give a small spritz of ethanol to the foam when filling the travel bottle but this is impractical for commercial production

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 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. ????
