    You could totally market a small version of this to coffee shops everywhere! Keto-coffee blends butter and coconut oil into coffee, and it's difficult to keep it all in suspension.

    it works very well with a vertical blender! that is the way I make my own face and body cream. and I do mix oils and water, and they do not separate after, not a sweat! so physics tells us why water and oil do not mix: water is denser (has more molecules), and that is why it separates below the oil. but, if you put less water, and more oil, and stir them extremely well, with the help of a vertical mixer, in a vertical jar for ex, it will break large drops into smaller ones. but I do this, first heating the oils on bain marie, and then letting it cools down a bit. so, it seems like temperature and stirring with great speed to break the particles in tiny ones, helps to mix oils and water, and create emulsions.

      it stays emusified for forever, in a face cream, if you add a little bit of white wax, on bain marie, too.

      Water is polar. Oil is not polar.

      Is is possible with petrol and water emulsifier?

      Have u figured out that a squirt bottle fits on top of the vitamix and will drip oil into your blender hands free while you begin cleaning up your station?

    Thank you so much for this video. Question can you do it with waste vegetable oil that has been used in a deep fryer? How much does the machine and where can I get one?

      @FacePwn64 thank you for the information. What is the price for one and where can I buy one?

      Dear Rab Rab,
      Waste vegetable oil, such as frier/cooking oil can be emulsified. In fact Hielscher ultrasonic reactors emulsify used cooking oil with methanol and catalyst at large scale to make biodiesel (see: www.hielscher.com/biodiesel_ultrasonic_mixing_reactors.htm for details).
      How much material would you like to emulsify using ultrasonics? Would you like to make clear nanoemulsions (see: www.hielscher.com/ultrasonic-production-of-stable-nanoemulsions.htm).
      For pricing and ordering, please contact us (e.g. use the form at www.hielscher.com/oil-in-water-emulsions.htm)!
      We will be glad to work with you!

    How small (size) are oil droplets after emulsion? How much emulsifying time is needed to reach the smallest droplets size?

    • @HielscherUltrasonics
      @HielscherUltrasonics  9 місяців тому +1

      @niccololovino9650: As so often, it depends on many factors. Some of our customers make 10-30nm nanoemulsion using Hielscher sonicators. You can get to nano in short time. There is another video in our channel showing the production and measurement of a nanoemulsion. See ua-cam.com/video/Nm00Xck_KGA/v-deo.html
      We will be glad to discuss your emulsion project with you. Please contact us directly! Please subscribe for more interesting videos.

    How long does this emulsion stay stable for? A vague question, so more specifically, after how long at say room temp will you begun to see the oil fraction start to form a layer again?

    • @HielscherUltrasonics
      @HielscherUltrasonics  Рік тому +2

      @Wags Slave: This depends on multiple factors. You can make stable emulsion, that won’t separate at room temperature for days.

    Can you emulsify water into oil with this method?
    I would love to see what happens if you try to use it for frying food.

    • @HielscherUltrasonics
      @HielscherUltrasonics  2 роки тому +2

      Yes, you can emulsify water into oil (aka water-in-oil-emulsion) , to create small water droplets (disperse phase) in an continuous oil phase.
      How much would you like to emulsify? We would be glad to run a test for you in our technical lab. Please visit www.hielscher.com to contact us!

    It can stay emulisfied for long if you use surfactant to stabilize this emulsion. We stabilize water-bitumen emulsions by this method

      Dear Benoit,
      In this video, the ultrasonic homogenizer makes an emulsion of oil in water. The same ultrasonic equipment can be used to make liposomes. You can find more information about liposome preparation at www.hielscher.com/ultrasonic-liposome-preparation.htm .
      If you would like to make liposomes, please contact us! We will be glad to assist you with more information, protocols, in-house testing and ultrasonic equipment.

    Is there separation again after being stored for several hours?

    • @HielscherUltrasonics
      @HielscherUltrasonics  4 роки тому +2

      This depends on the oil, the oil/ water ratio, the sonication parameters and the emulsifier / surfactant used. Ultrasonic emulsification can prepare nano-emulsions with stability over several years.

    • @HielscherUltrasonics

      Sorry we cannot help you breaking the emulsion. Actually sonication makes smaller emulsions that are harder to break (more stable).

    is it high or low frequency ultrasound?

    • @HielscherUltrasonics
      @HielscherUltrasonics  4 роки тому +1

      This is low frequency, high power ultrasonics: The Hielscher UP400St runs at 24kHz.
      More information about the UP400St can be found at: www.hielscher.com/up400st-powerful-ultrasonicator.htm

      Dear Olivia,
      Hielscher makes low frequency ultrasonic homogenizes with frequencies from 18kHz thru 40kHz. Other frequencies for special applications are available on request.

    Does this introduce air bubbles into the mixture?

    • @sandim_a1634
      @sandim_a1634 5 років тому

      You can use Thinky Mixer from Japan for degassing method

    • @chrisdenicola4336
      @chrisdenicola4336 4 роки тому +1

      in theory its doing the exact opposite.. its supposed to remove gasses from the liquid.. this is a form of degassing

    • @HielscherUltrasonics
      @HielscherUltrasonics  4 роки тому

      when applied properly, ultrasonic does not introduce air or gas into the emulsion. Indeed, ultrasonics is often used as degassing method.

  • @m8272m
    @m8272m 8 років тому +10

    I don't think this is a well produced video, considering your target market and their assumed level of knowledge about emulsification... this might be impressive to someone who doesn't know much about the topic, but with that amount of force/time, a cheap stick blender could have achieved those results *for as long as you demonstrated*. Do your emulsions last longer, ounce for ounce of emulsifying ingredients (I realized you used none in this demo) compared to your competitors' products? It's unclear because the video didn't provide much information. I'm hoping this is constructive.

    • @abnersilverio
      @abnersilverio 7 років тому +3

      This works without emulsifying liquids which is what makes this so special. The molecule size can be reduced to 30-50micron and it will last a few months before it separates without surfactants or emulsifiers. I don't think it is possible to break it down using shearing mixers this fast or even come near as small particle size either.

    • @Kloashut
      @Kloashut 6 років тому +2

      Assuming you use normal vegetable oil, I'd be really curious to hear/understand how you can keep those microparticles dispersed without the usage of a surfactant. I prepare particles by ultrasound/with ultra turrax/microfluidics/nano droplet/ salting out etc etc, but unless I use modified oils/polymers [amphiphilic] I cant keep the emulsion stabily dispersed without the use of a surfactant. @ Abner Silverio: " I don't think it is possible to break it down using shearing mixers this fast or even come near as small particle size either": Ultra Turrax 5 min, 23000rpm: particles around 100nm with a low dispersity index

    • @HielscherUltrasonics
      @HielscherUltrasonics  4 роки тому

      The stability of an emulsion is influenced ny various factors such as the oil, the oil/ water ratio, the sonication parameters, the emulsifier / surfactant used as well as the storage conditions. Ultrasonic emulsification can prepare nano-emulsions with stability over several years.
