Actually a lot of levels seem not fine(too high):
As said level of essentiel oil also panthenol, EDTA and maybe shea butter .

Ph changes the viscosity so i guess it changes the slat curve, wich is the highest? May in slight acidic range

@Perry44 @chemicalmatt @ketchito @Abdullah i’am facing same problem low density of after shampoo with keys ingredients :Water, Cetearyl Alcohol, Cetrimonium alcohol, Ceteareth-20, parfum, preservative.
So the best process I reached work with turbine at 30 hz (1800 rpm) for 15 minutes(T=75°C) then slow the speed to 20 hz just for economical reason at T=60°C I stop the turbine then at T=40°C I return on turbine to 30 hz for 10 minutes
All the process I have anchor agitator works from 25 to 35 hz
And at Cool phase I tried work lower speed 25 hz and It gived lower viscosity
Please any solution to solve low density of after shampoo then any correction and improvement for process? Any share, input please
-
@Graillotion need your expertise for solving that please.

Emulsifiers can be also thickner so my question about that . If i have acess to neowax 165 or other i Will not work and ask to replace them. Unfortuently we are surfering from the absence of auto Emulsifiers for a long time now this push to do that…
-
Not really pricise value just thick cream and the level of emulsifiers Will be better lower then seven with 5% and can be more of cetearyl alcohol .
-
You are welcome
-
@PhilGeis thanks for the interesting add, first time I hear about that.

My I will check the pH of mine and tell you but I guess even whitening tooth paste are basic”i know that acidic pH is more efficient for limestone… “
-
Same constation about ph of tooth paste almost are basic however we can find a lot of them contain sodium benzoate so how use it is preservative for toothpaste ph range?

I haven’t problem in viscosity my formulation is pretty good just the product has low density between 0.91 and 0.93 knowing that it can reach 1
So I want what can I improve in process or formulation to reach density equal 1 just when i’am finishing from production not after days
-
@Aniela whatever thanks a lot for your comment.
-
@Abdullah yes it is hair conditioner, and Cetrimonium Chloride not alcohol Cetrimonium and Cetearyl alcohol near to 5%
Also I worked with and without vacuum and really I didn’t notice any important difference.

Soaping in cream is normal if it doesn’t persist this is something of thinking about the box.
-
i don’t think that 0.8% GMS SE cause soaping , actually i find it from best emulsifier for getting better emulsion , may adding silicone will solve the problem (i find that ceteareth-20 not really good for emulsion texture).
-
@KRISTIANA any answer after giving the laboratory details? then when the recirculation is needed? And What is the best cooling rate for emulsion according to you?
-
the batch in laboratory is 100 grammes with turbine agitator.
There is no recirculation system in industrial batch. (is the equipment is qualified I already make description if you can share your opinion about that question)
The process is described in specific paper for sure with all details… And the operator is doctor in chemistry.Cooling speed for laboratory it needs just an hour to decrease from 75 to 40 °C however in industrial batch it needs more then 4 hours.
Wich rest you will check the droplets of emulsion and what will benifit knowing that?
-
Thanks
-
@Herbnerd thanks a lot for you interesting share, I want to know why your preference is sodium cmc and according to what you chose sush surfactants?
-
@chemicalmatt Can you tell me what are the heavy oils please?
-
@chemicalmatt any idea about the stability of Glyceryl Stearate S.E. @ 4.0% | Polysorbate 80 at 1.5% please.
-
Gms se alone will not lead to stable emulsion.
-
Wich is your level of ethoxylated ingredients?
