If you tell us what kind of surfactants you have available we can be a lot more helpful. Can you get SLES? Cocoamidopropyl betaine? Many products on the market use nothing more. ALS? ALES? A better option. Sodium cocoamphoacetate? And, any refatteners? (EG: PEG-7 GC)

If you really want to know properly, the thing is to try different esters. I’ve forgotten the name of the manufacturer for the moment… German sounding name… they supply a whole range of esters from one that is much lighter than water, to ones that are basically a grease. Obviously you don’t want to be asking for samples from all of them, but I got samples for about four of interest that I chose from their chart. They’re listed in order of viscosity. The lightest one is like water or lighter, certainly a lot lighter than eg capric/caprilic tri. The heaviest is like vaseline. As I hoped, it’s possible to craft a cream with the properties you desire, simply by choosing the correct combo.

I’m very sorry to hear about this case. It is the same kind of thing that caused a huge number of complaints about Harz products. This happened to both my dogs. They were covered in lesions, open wounds. MIC or MIT has to be banned in personal or animal care products. That is my position. The evidence is overwhelming that zolinone preservatives are absolutely terrible. If any formulator here is tempted to use them, for the sake of your clients, DON’T.

It really is quite simple. Make two experiments. Assume they used 99% pure in (1) and 90% in (2). Measure the resulting pH and viscosity.

Hardly surprising with SLS. Making shampoos that work properly is not that easy, as you will discover.
-
Not worth wasting your time and materials. Besides, SLS thickens with electrolytes.

Can soap be used as a solubilizer in this case? If yes, in what percentage?
It’s possible that potassium cocoate could dissolve it. You would not want to apply that to the skin, though. -
Use colours in the foam.
-
Sounds similar to another Emulgin I tried which had the same polyester but with decyl instead of lauryl glucoside. It caused a rapid crop of whiteheads when used in a moisturiser. Terrible.

Pepper will not dissolve. You are wasting your time.

“Light the blue touch paper and retire quickly to a safe distance”

You can use some other oil and add stearic acid in sufficient percentage. Must be hot process of course.
-
I did not continue with this experiment so I can’t comment further.
-
could you point me in the direction of an “ideal” cleanser.
Sure. Try what I use: Stepan APB (All-Purpose-Blend). It’s excellent. -
Sodium benzoate for hair products, KEM NAT for skin products.

Thiazolinones are an absolute no-no as far as i am concerned. I have direct bad experiences with them. My wife had AD on her hands using a dishwash detergent containing it. My daughter’s hair began falling out due to the same preservative in Sedal hair conditioner. Both my dogs had serious AD due to being shampooed by a vet’s shampoo using that preservative. And so on. Should be banned. I am in fact running a public safety campaign on Facebook against products that use it.

18% is rather a lot. 12% is more usual. I would recommend reducing it to about 12% and bottling the day after batch production.

In my opinion, as a man, your husband would be better off improving his shaving technique so as not to have the problem in the first place.

caustic soda IS lye.

It’s a boring standard formula like 99% of the SLES in shops. Use more surfactant.
-
Thanks. I don’t use my brand page because I don’t believe in negative marketing. I’m just trying to help consumers identify products that cause dermatitis.

I don’t think you can “use them” on crystalline salts if that is what you mean. I don’t know for sure, but I suspect they get their colours from crystallising in a dyed solution.
-
The formulations are not expressed in proper percentages. I really haven’t the inclination to do all the calculations for you.
