Thanks for amazing knowledge you gave here. I have a question , if I want to suspend 5% herbal water based extract into LLP oil which emulsifier shall be used to homogenize the hair oil product?

Hello. Amazing presentation! I was wondering, perhaps you could point me in the right direction. I don't work with cosmetics, but with printing inks, but since both industries rely on water in oil emulsions, the surfactants and polymeric surfactants are so similar in HLB behaviour. But regarding viscosity, which kind of polymers do you prefer for the mesh effect? Or in other words, how do I go about selecting the best for my water-in-oil emulsion? What chemical family of polymers would be best compatible for increasing viscosity in a soybean oil continuous phase? Thank you so much.
Hi Victor - remember where oil is the continuous phase then you need an oil compatible rheology modifier. I love quaternised clays (e.g. stearalkonium hectorite etc) but I don't know if they would suit your application (I'm not an ink chemist!) But they are good at particle suspension, like in oil based foundations, so may be suitable. They usually suit non-polar lipids but you can get some grades suitable for polar lipids too. They would be my first pick but please speak with the suppliers in your industry for ink-industry suitable materials like these. Hope this helps!
hi, is there any information available for larger batch production,? Hope you can bring some information to start with. Thanks a lot, very useful videos!

Having some electrolytes present (I emphasise: SOME) can help with the polarity of the water phase, increasing its attraction for self, to 'hold' the water droplets together and in dispersion. Too much acid, however, is not suitable. If your w/o emulsion is not holding together because of a highly acid environment (
@@theinstituteofpersonalcare6401 This helps a bunch, thank you. I simple wanted the ph of the water phase to be skin friendly, which is about 5.5, so this is perfect. I would like to know whether the acidity could possibly interact in some way with other electrolytes, Such as MgSO4. If so, should I not use it all all, as more than one kind of electrolyte is unnecessary? Or can I have an acidic water phase with NaCl instead?
While 5.5 is 'ideal' the skin is also perfectly happy with 6.5 - 7 or slightly more! Water is 7! So it doesn't matter especially in w/o emulsions; but it may matter for your preservative or actives. Hope this helps, happy formulating!
Hi Chris, yes we use the HLB system and a combination of low HLB value emulsifiers - that is part of the HLB system principles. I hope this helps, Belinda

It can be a bit problematic as the liposome would go into the water phase - its not impossible, but it may be difficult. You’d need to make a sample and see how stable it was over time.
@@theinstituteofpersonalcare6401 how would you know if such an emulsion is failing? As in, what would the consistency be like to alert you that the emulsion isn't working?
hi! What about for preservatives that are pH-sensitive? Since we can't determine the pH of water in oil emulsions, how do we go about this? I hope you can help me figure this out. Thanks

Just relying on emulsifiers won't give you long term stability assurance - you need the rheology modifier that is compatible with the oil phase to give you a physical barrier to coalescence/instability as well as the emulsifiers.
I have a question, I am making a water in oil mineral sunscreen, but the stability of my viscosity is constantly increasing after different store conditions from 37C to 50C, what do I do to maintain stable viscosity?

EMOSMART range of alkanes will be great for the light feel. Also, EASYNOV is a liquid emulsifier that can help make w/o emulsions without heating.

Thank you.
your presentations and formulations .. really helped me too much .. thank you .. Happy formulations ^_^
Thanks Areej, Happy formulating, please subscribe to keep updated of the latest videos and let us know if there is something you'd like to see! :)
May I ask why you referred to beeswax as an emulsifier? You have wonderful videos btw.
Beeswax has a low HLB value of 4-5, which means it can help form and stabilise water in oil emulsions.
@@theinstituteofpersonalcare6401 Thank you, I see what you mean 🙂
i want to add glycerin in soya bean oil, kindly recommend some good surfactant.

Is it possible to have an acidic water phase in water in oil emulsions??? If so, what complications can arise and how does one troubleshoot them?

Thank you.
whi just not use vacuum blender??? no chemicals needed you can even mix 50:50 oil water - stable solution.
