You seem to have a lot of overlap in your formula with similar ingredients performing similar functions (e.g. EGMS/EGDS/GMS and PQ7/PQ10/GHTC/Cetrimonium Chloride). Try just using one of each at the maximum recommended percentage to see if this makes a difference.
Try reducing the jojoba oil and vitamin E to 0.01% as these raw materials will reduce your foam and just wash away so don’t have any real benefit.
You could also try increasing CAPB to improve foaming.

You should include your location and types of products you are interested in to your post for a better chance at getting a response.

Taurate surfactants can be thickened with amphoterics (such as cocamidopropyl betaine) and salt (https://www.clariant.com/en/Business-Units/Care-Chemicals/Personal-Care/Sensorial-Effects/Surfactants/Taurates-mild-surfactants). Is there any reason you haven’t tried an amphoteric?
Glucoside surfactants are difficult to thicken so I would suggest lowering the amount of glucosides in your formula.
Try making the formula without all of you extracts and then adding them in one by one as the ethanol in the extracts could also be contributing the low viscosity. Reduce them to claims levels if necessary (0.01%).
Hope this helps 😊

We recently moved to Saboderm DOE (Dicaprylyl Ether) from SABO S. p. A from the Cetiol OE. There is also Cosmacol OE from Sasol.
Not sure about suppliers in the US (I am in Australia) but these are just a few more options to help in your search.

What are your clients limitations on surfactants? Glucosides are difficult to thicken and aren’t great with foaming. The easiest option is to look for anionic surfactants that you can thicken with salt or CAPB.

The main difference seems to be the inclusion of sweet almond oil in the first formula but not the second. Is it possible that the sweet almond oil is oxidizing over time?
-
Have you considered an oil soluble Aloe Vera extract? I am not sure if they have similar properties to the water soluble extracts but it would be easier to incorporate into an oil.

Eeew! Mold is natural 🤮
Tallow is having a resurgence in popularity at the moment so it is not a wonder that they have jumped on that bandwagon.
Looks like a case of ordinary (possibly inferior) product - lots of money for marketing.
I wouldn’t use it.

We need your formula to help more.
When a product with a dye loses color it is often associated with UV exposure. What is your packaging?
-
The Syn-Ake has a lot of glycerin which can be sticky. Do you have any other glycerin in your formula?
-
Sometimes a pink discoloration is caused by bacterial contamination or by some fragrances discoloring. It could also be caused by a reaction between some of your ingredients.
It is possible that you have bacterial contamination due to the honey.
You could try a knock out experiment to see if one of your additives is causing the issue.

A quick google search will lead you to dozens of cold cream formulas.
For example: https://pharmaeducation.net/cold-cream-uses/

Cold Cream: Uses, Formulation, Preparation, Tests
Cold cream is a water in oil (W/O) emulsion. It is known as Fatty Cream according to European Pharmacopoeia.

Croda states that the typical usage is 1- 10% for the BTMS-25 but this seems to be based on usage in liquid products. They also have a conditioner bar formula that uses 59% BTMS-25. Which is about 15% active BTMS.
You can also check Cosmetic Ingredient Review (CIR) for guidance.

I have experience in several household products. I am happy to help in this forum setting. Just post your formula and you issue.

Was your xanthan gum properly hydrated in the manufactured batch?
-
Sodium Bicarbonate is often regarded as irritating by many people when used in these types of products.
Try looking at deodorant actives such as Triethyl Citrate or Ethylhexylglycerin for better performance.

We have batch instructions which are usually only one page long.
The batch instructions have the list of raw materials with amounts required and their location in the warehouse at the top. The raw materials are divided into sections (e.g. Part A, Part B) if required.
Below the raw materials is a brief method on how to manufacture the products.
For example some instructions might be:
Add the raw materials in Part A to Tank 7 in order and stir until combined.
or
Add the raw materials in Part C to the tank when the temperature is 40oC (or less).
We also add in some basic safety instructions when working with Caustic, strong acids etc.
Fortunately our manufacturer’s are experienced or work with an experienced worker until they are competent so they don’t require too many details. You may require more details if your workers are inexperienced.
We don’t include information about the use of the equipment (tanks, pumps, blenders, emulsifiers etc) in our batch instructions. This is in a separate SOP for each equipment type.
Our products are pretty simple surfactant blends, emulsions, blended powders but if you have more complex products or equipment you might need more details.
Hope this helps. ????

You are also forgetting that making a good enough (but not great) product with excellent marketing is generally what is needed to succeed in the cosmetic industry. Marketing plays a very big part of selling cosmetics.

Does it spray well with that much Polyquaternium-7 in it? If not you may want to reduce the PQ-7.
-
What is the pH of your moisturizer? Glyceryl stearate SE needs a slightly alkaline to be most effective.
-
Stearic Acid is going to be draggy on the hair. Try replacing it with some more SCI.
-
Cocamide MEA has some refatting properties so this may be what your testers prefer rather than any difference in silicone deposition.
-
Ethylhexylglycerin is only slightly soluble in water (0.1%). It is is more soluble in glycols (e.g. butylene glycol) and also in paraffin and silcone oils.

In laundry washing machines you don’t want much foam. In front loading and high efficiency machines foam can cause issues with the sensors.

You are correct there is more in the document. This particular tank is a fixed speed tank so no need for additional settings information but that should be added if required. The definition of “until combined” is covered in training our staff and just means until homogeneous. We manufacture simple products so our instructions don’t need to be too complex.
