All the memory hit back, this is my first cosmetic product <3. I still got problem with “air entrapment” when scale up to commercial product, our vaccum homogenizer not so much suitable for manufacturing toothpaste. Special thank for your help @Herbnerd.

The answer to my old topic about Glycerine may help you.
chemicalmatt said:Glycerine is a polyol just as are diols (propylene glycol), which are all part of the alcohol family. All small-carbon chain alcohols decrease foam and viscosity. PEGs with longer chains do not reduce foam but they will reduce viscosity in most cases. Those hydroxyls act as a tertiary surfactant competing with your longer chain surfactants. David beats Goliath so to speak. -
I think you should try divalent salts like magnesium sulfate to reduce the amount of salt used.
-
I think you should raise a bit E-wax NF to 3,5 - 4% and combine with 1 polymer like xanthan gum or carbomer (0,2 - 0,5%) for improving stability of water phase.

I was using 8oz of water! you said 1.6 oz to 1 gram of Suga Mulse wont suffice? Suga mulse was pretty expensive…. so how much should I use?I found the instruction for Poly Suga Mulse D9. Hope this can help you.

I used it in eye drops and liquid (pharmaceutical product) for increasing solubility of preservatives or oil-soluble vitamins . pH 4-6 or 6-8 and never observed discoloration (in transparent eye drops).

MemberJanuary 26, 2021 at 2:52 pm in reply to: Why does Glycerin reduce viscosity of shampoos?Thank you @chemicalmatt. If glycerin competing with long chain surfactant, i can still use it in low concentration (maybe 1-2%) for pre-mix with gum, is that right?
For 2nd question, I realized conditioning agents have many classes : occlusion, silicone and their derivative, polymers, proteins, cationic surfactant …. So each of them have different way to add in shampoo or skin care product. I will very happy if we got a webinar for this. :smiley: -
We use PEG-40 Hydrogenated castor oil (Acrysol K140 or Eumulgin CO40) as the alternative for Polysorbate 80. But IMO, almost the solubilizer will produce foam if they are surfactant.

You can try Euperlan PK 711 Benz if do not mind Cocamide MEA in your formula. It works well with cold-process.
-
You can try with Euperlan from BASF.

@Herbnerd. A kitchenaid mixer is exactly what i need !!!. I never think about this before. Thank you so much.
I work in a small company main focus on health supplement, so a Silverson mixer or somthing like that for cosmetic R&D only in my dream. :smiley: -
@Herbnerd Thank you for your advice. I will try add Carbopol and Sodium CMC in glycerol.@ketchito Thank you. I read this article and another about dispersion Carbopol, but my lab dont have enough equipment. I just have magnetic stirrers, this very hard to homogenize when combine 2 polymers. So I need disperse Carbopol in solvent before swelling. When scale up, with vacuum homogenizer, all things will be easier.

You can dissolve with hot water (approx 80°C) or in a saturated salt solution if you use salt as a thickening agent.
-
You can dissolve PEG - 150 Distearate in hot water (approx 70 - 80°C) with slow mixing to avoid bubbles. Just dissolve it alone, you can add to your SLES before mix with CAPB. And what is percentage of PEG - 150 you are using?
