Thanks. I am working with a large marijuana cultivator in the USA with a view to reducing the incidence of botrytis, he's losing 90% of his crop. It mostly goes for edibles and that part's OK, but it is the smoking part that concerns me. I have alre…

I don't even have running water in the lab. I take all the used gear to a washing area.
-
If that's your reaction then it appears that those are not mild surfactants at all.
-
(Quote) Tell that to Coca or Pepsi Cola. That is the preservative they use.
-
Drop the pH to 5 and sodium benzoate is perfectly adequate.

B3! Sure to be. Someone offered me a 500mg supplement. I took it. Within half an hour I thought I was going to spontaneously combust.

I hope to get my lab up and running again in the New Year so I am looking forward to 2021!

would you like to comment ? - Not really. This is someone else's thread. I saw your question and all I can say is, cetyl alcohol is not found in commercial shampoos, do you think there may be a reason?
-
It's basically silica gel (isinglass) and dimethicone.
-
Same problem. CDEA is not a thickener. Thickeners: CMEA (slightly), PEG-150 distearate, methyl cellulose, glucamate VLT, certain gums (poor sensorials), carbopol types (formulation problems)
-
This is the ongoing problem with relying on salt thickening. I found it pretty much impossible to make a product of a required viscosity using salt alone. You will probably have to add thickeners.
-
Provided your preservative system is robust, you don't need to sterilise packaging.
-
Without listing the formula we cannot help.
-
What do you mean by "essence"? Are you talking about fragrance oil? Adding this always decreases viscosity. Often, by a lot. Salt thickened products are quite unstable in viscosity, the slightest thing messes them up.
-
I can't see anything here suspicious except as Perry said, the fragrance. Which seems high at 2%. The preservative system looks very adequate so I doubt it will be 'off', but have it checked anyway.

ngarayeva001 I use my own shampoo on my dogs now. (Only sodium benzoate used as preservative.) I am unable to have them bathed by a vet because the vets all use shampoos sold for veterinarian use, and none of them have any kind of ingredient list. I…

I suggest you simply copy one of the many, many products on the market that are based on SLS, SLES, and CAPB.
-
Yes.
-
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 refattene…

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 th…

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 an…
-
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.
