@PhilGeis thanks
What about ALS? -
@PhilGeis for how much time?
-
@Perry thanks
Were they using SLS powder or liquid?
I use SLS powder and for 10% SLS i need 8% citric acid powder to reduce the pH to around 5. -
@PhilGeis it will be open when vassel during spring alcohol. Do you mean if i close it after spraying i will approach flammability?
Yes i can use hot water.
-
@PhilGeis which surfactants increase the pka of organic acids?
What is the lowest pH at which SCI and sulfosuccinate can work properly?
-
@PhilGeis how should i use alcohol?
I mean is it ok to put some alcohol on a garment and apply to surface of tank or any other method?How should i sanitize the 2 meter pipes?
-
@Perry thanks.
Obviously it may be mild enough for scalp. So SLES/SLS without CAPB can also make a mild surfactant.
what would the ratio of SLES/SLS be to make it mild? -
@Graillotion what cationic surfactant were you using?
Was it unstable without water phase thickener? Because cationic lotion i see in internet don’t have water phase thickener. -
@ketchito that is interesting. I should try and see that.
What about other amphoteric surfactants like lauryl Hydroxysultaine? -
@ketchito you mean this shampoo is preserved in pH 6 with sodium benzoate?
What do you say about stability of CSI and sulfosuccinate in pH below 6? -
@zetein yeah in the past they used coco betaine but in some new formulas there wasn’t any amphoteric.
Maybe i am wrong but as i know SLS and SLES doesn’t make structured system. And this doesn’t have any other surfactant.
-
@Sincityfire i really like CSI and disodium laureth sulfosuccinate but the supplier say they are stable only in pH 6-8. I work in pH 5. I don’t know if i should trust these informations.

@Perry
1. is there any general rule that what types of surfactants need high amount whater phase thickener what what type need less or not at all?2. What factors influence the need for water phase thickener in emulsion?
3. How to reduce the next for phaterphase thickener with non-ionic Polyglyceryl 6 distearate as emulsifier?
-
@Perry thanks
Does type of emulsifier have effect on stability of emulsion without water phase thickener?
I have seen many lotions with cationic emulsifier that doesn’t have water phase thickener.
For example this lotion from AvenoActive Ingredient:Dimethicone 1.2% (skin protectant)Inactive Ingredients: Water, glycerin, distearyldimonium chloride, petrolatum, isopropyl palmitate, cetyl alcohol, avena sativa (oat) kernel flour, benzyl alcohol, sodium chloride -
@PhilGeis how much contact time of alcohol 70% will sanitize the equipments? Seconds or minutes or more?
-
@PhilGeis which equipments should i sanitize?
Tank, homogenizer, Pipes, other small equipment Or all equipments?How many times and when should i sanitize with alcohol?
-
@ketchito thanks
What is charge density?
How to know which surfactant has how many charge density? -
@zetein thanks. Very helpful chart
-
@RedCoast thanks
-
@PhilGeis do you mean that chelating agents will reduce the effectiveness of Piroctone Olamine?
-
@PhilGeis it follows all these guidelines.
how do you sanitize?
i wash them properly befor and after work and store them dry and clean. What else should i do for sanitization and why? -
Graillotion said:Abdullah said:@Graillotion that is very good.
Can you share a photo of your cream that how ot looksLooks like this….and I think a blue container enhances the effect.
But I dispense from a clear plastic bag…into jars…and it is a nice light blue in the bag.
Thanks

I like guar Hydroxypropyltrimonium Chloride more than 400 cps PQ10.
