Great video, cheers
Thank you for watching!
Love your channel. The content is professional and thorough, but still simple to understand for those of us who are not professionally educated. Do you have any videos demonstrating the failures of formulating? For example how to determine when you broke your polymers or troubleshooting common problems with formulas. Similar to the white rubbing video, but other examples. I'm also curious if you have any content on carbomers specifically or thickeners in general. There are many different types and uses for them. It is difficult to know which to choose for each application. I have read about many of them, but there is a big gap between advanced technical content which can be difficult to understand, and amateur content.

Happy Formulating!
hello from greece. A video about the importance of using vacuum in the production process would be very helpfull
We’ll add this to the list thank you!
This was so useful thanks! Would the overhead stirrer replicate what a stick/immersion blender (with a standard blade) could do, but for larger batch size? And which of the stirrer heads you showed would do that best? The propellar or disperser head?

Thanks for this video! Wasn’t sure what low and high shear meant

Shear sensitive liquids change viscosity when under stress or pressure, such as when they are hit by the impeller inside a pump. Some liquids become less viscous with increased force (called shear thinning or pseudoplastic), while others become more viscous with increased force (called shear thickening or dilitant)
Always amazing advices. I always see those sheat but what about of you have a 20-40 kg batch production or more? What are we supposed to shear with?
A homogeniser for larger batches has the same shear through the head unit, its''s just a lot larger.
Thank you for the great explanation, is it possible to get one machine that can provide low and high shear with attachments or do you recommend two machines.
The one thing I did not get was the volume these machines can handle as this was not mentioned.

Hi, Belinda. Regarding the dispersing head (beginning at 3:10), can you please describe what happens to the formulation if you were to use it at, say, 2000RPM? Does it then start vortex-ing and adding air into the mixture? Many thanks.
Depends on the volume and viscosity of what you are stirring. A dispersing head at that speed will shear materials so is not suitable with materials that should not be subjected to shear. If the solution is low viscosity it is likely to create a vortex. If high viscosity and you need to create extra shear, it is a good choice (eg dispersing pigments in oil) - but probably doesn’t need to be at 2000rpm to get the desired result. Depends also on the volume.
Hi Belinda, which stirrer head you would advice which can go well with every kind of emulsions??
It depends on what else is in the emulsion - if you have ingredients that would be affected by high shear, then you should only use the propeller stirrers. Otherwise, high shear is best for emulsions, but this is not suitable advice if you are using ingredients in your formula that are affected by high shear. You can learn more about emulsions, gums and polymers and processing methods in our Diploma of Personal Care Formulation: personalcarescience.com.au/CosmeticScience/DiplomaofPersonalCareFormulation-479/
Hi! Excellent video! Whitch high shear element homogenizer do you recommended for Mascara formulations?: 1-10 um (fine), 5-20 um (medium) or 10-30 um (big).
Thanks!!
Thanks for watching! It depends on what else is in the formula, and if you have shear sensitive ingredients there or if you have ingredients that specifically need shear. Please purchase consulting time with us: personalcarescience.com.au/Advice/Advice-2046/ and send us your formulation details as I can’t comment without reviewing your specific formula and ingredients.
im wodering, if i have my own factory, how do i test the quality etc if i dont have icp, gc, hplc in my lab? hope u did video telling us the main testing equipements for the cosmetics

Thank you this is very helpful. I have one more additional question. Does the smaller particle size provided by homogenizer give significant result in emulsion absorption. I mean is it that much difference compare to overhead stirrer. Thank you for your time
Thank you for watching! While smaller droplet dispersion will usually result in greater amphiphilic absorption and stability, it can also depend on the emulsifiers you have used and of course you also have to consider what else is in the formula before exposing it to high shear e.g. if you have shear sensitive polymers then you can’t expose it to high shear after adding them.
Is possible while using powerful homogenizer to make an emulsion, then smaller/thin particles are suspended in water phases in two phases products?!
i love these videos
Please email us for full formulation, method and supplier details: info@personalcarescience.com.au we provide this free. Happy formulating!
@@theinstituteofpersonalcare6401 I emailed! But I did not get a reply🥹
Are the natural gums (xanthan, guar..) shear sensitive? Thank you for your videos.
No, they are not shear sensitive. Happy formulating!
very useful

I have a problem in industrial making double phases hair conditioner, would u plz kindly inform me which mixer blades is proper for micing silicone phase?
Please note the selection of the mixing blade is normally more important for your gums/polymers and your emulsifiers, but may also depend on other elements such as volatility of materials or the types of ingredients used. It can vary significantly, depending on your specific formula. Please study with us as I can’t give you a ‘general’ answer, it depends on too many things.

Whats the angle of your propeller stirrer head, 30° or 45°? Does it push the liquid up or down?
In the lab it is mounted in the centre but I'm able to move the beaker to alter the angle. In larger production batches it needs to be mounted eccentrically to avoid capturing excess air.
But when I look in the technical specifications of ultra turrax Ika , I found this : permissible ambient temperature is 40°C. What does that mean? Can I use it to homogenise my emulsion at 75°C? Help me Belinda please 😊
I use it with hot products all the time - please check with IKA what they mean by that???
Can you use this for hair products
Absolutely! Please email us for full formulation, method and supplier details: info@personalcarescience.com.au we provide this free. Happy formulating!
I’ve watched 2 videos and do not see what a “sweeper blade” looks like. What is a sweeper blade?
Can i use homogenizer instead ? Thank you so much
Homogeniser is high shear - you can't use this if you have shear sensitive materials in your formula.
Hii to make large production of foaming bath butter( cream soap )I’m having a problem. Lot of powder Chucks coming . To break manually it’s taking lot of time. I planned to invest a machine. But very confused 🤷♀️ which agitators is useful to break that lumps.planning a double boiler tank with attached mixing agitator.can you please please help for this. Which machine and agitator/mixer helps for this problem .🙏
Please do this workshop, which shows you the equipment and methods to use when moving to manufacture: How to manufacture cosmetics: personalcarescience.com.au/Advice/CosmeticManufacturing-2049/ :)
I need these machines to formulate my products
Thanks for watching. Please find information on lab equipment here: th-cam.com/video/Yj7Q0WTr2X8/w-d-xo.html
is the model of the homogenizer shaft S 25N -18G?
please contact us for details on our equipment: info@personalcarescience.com.au
Great Content💓💓
Can i use it to mix #Syrups???
It would depend on what materials you are using. Some materials are shear sensitive, so only low shear can be used when mixing. If you would like to learn move about different materials and suitable stirrers you can enrol in one of our courses.
@@theinstituteofpersonalcare6401 ok THANK U💓💓💓
IKA is my dream, but it is extremely expensive. I have contacted them and got the price list. It is about 5000€.
We have this video all about equipment (from beginners to advanced): th-cam.com/video/Yj7Q0WTr2X8/w-d-xo.html - please watch this video as Belinda explains all about the equipment and what to look for when purchasing equipment (from beginners to advanced needs).
Very informative . Can you use this machine in place of the stick blender?
Hi Adaobi,
Yes - stick blenders tend to cut materials and add a lot of air to a formula so these stirrers are a much better choice for more professional formulations.
Happy Formulating!!
Can I buy it if yes then where should I buy
Thanks for watching! Please contact us for the full formula, method and supplier details - FREE! info@personalcarescience.com.au Happy formulating!
What if you wanna stir bigger batches
Thanks for watching!
You can learn all about this in the link i have provided with all of our Workshops, personalcarescience.com.au/Workshops/Workshops-2110/
Happy Formulating!
remember its the TYPE of head you use not the RPM 😏
