Thanks Sommya, we have over 70 different videos so make sure you subscribe and visit our channel to see what else you might enjoy! Happy formulating :)
Wowah I watched your new videos but this old video wanted me to have a chemistry mam like you in my school where I hate chemistry but when I started to study about skincare formulation I loved and wanted to learn more about chemistry loved this 🥺 video ❤️❤️❤️❤️ great explaination mam
It depends on what you want to make, please start by watching this video: th-cam.com/video/s0I7ZsGqUhk/w-d-xo.html and then please enjoy our free videos for other topics! If you would like to learn more, please email us: info@personalcarescience.com.au or for information on our various courses, please visit: personalcarescience.com.au/CosmeticScience/CosmeticScienceTraining-386/ Happy formulating!
Yes, everything is pre-weighed before the video to make it simple to add during the video. Please contact us for full formula and method: info@personalcarescience.com.au
It seems really easy to do experiment. I would like to ask two questions, how and when we should add vitamin E to our formulation,secondly if the final pH of my cream is very alkaline(12) so can that be adjusted or is my product totally wasted??? Plz guide,thank you
Please do our Cosmetic Formulation Fundamentals Masterclass to learn these foundation items: personalcarescience.com.au/Workshops/CosmeticFormulationFundamentalsMasterclass-7441/ It’s totally FREE! Happy formulating!
Thank you for this idea, we’ll see if it fits into our video schedule. In the meantime, you can learn with us. Please contact us for course information and which course is going to best suit you: info@personalcarescience.com.au
Great video. Is it important to hold phases for “20 mins” or just until oil phase is melted? Also, is there a difference in results if the water phase is pored into the oil phase vs oil phase into water like you’ve shown? Thank you!
We’re happy to provide the full formula, ingredient, supplier, input and method details, please email us: info@personalcarescience.com.au and we can send you a link to access ALL our free formulas and reports. Happy formulating!
Thanks for sharing this video, I really learn a lot :) Will the whisk method also works for other types of emulsifier (e.g. E-wax NF) without separation in just few days? I've always wanted to create smaller sample of lotion and stick blender is not possible for a small batch size.
Hi, I always recommend NOT to rely on your equipment - the materials should be enough (in most cases) with just a whisk in 100-200g lab samples! Method is important but small lab samples should come together without needing advanced equipment (In most cases). If you are getting separation in small samples from whisk stirring, then the formula needs fixing. Please email us for course information so we can teach you properly: info@personalcarescience.com.au Happy formulating!
We suggest beginners starts with a 10% dilution; when you are a bit more used to pH adjustments you could use a 30% solution. Hope this helps! You can also watch more detail here: th-cam.com/video/s0I7ZsGqUhk/w-d-xo.html and here: th-cam.com/video/kwvLAK3KauM/w-d-xo.html I hope that helps :)
There are various emulsifiers you can use, I would recommend you complete this workshop which has over 20 different emulsifiers from small suppliers you can replace it with! Can I use a different emulsifier: personalcarescience.com.au/Workshops/Emulsifierworkshop-3165/
Piston fillers are used to fill most personal care products like this, even foaming products. You can learn about manufacturing and filling equipment with our manufacturing workshops: personalcarescience.com.au/Workshops/CosmeticManufacturing-2049/
Hello! Thanks for your help in your response. If I change stearic acid to cetyl alcohol in the oil phase, then would that break the emulsion in any way?

You do need to cover it because even with preservatives, you need to protect product from possible microbial contamination from surrounding air. Learn how to formulate with active ingredients, including how to stabilise them in your formulas and check quality/stability with our Certificate in Advanced Cosmetic Science: personalcarescience.com.au/CosmeticScience/CertificateinAdvancedCosmeticScience-478/ or Diploma of Personal Care Formulation: personalcarescience.com.au/CosmeticScience/DiplomaofPersonalCareFormulation-479/

Hi, we get pH strips from various suppliers - look for ones that test pH from as low as 4 through to at least 9 depending on the products you plan to be making. It is also ideal if they provide pH in 0.5 increments, it helps you be more accurate - but it depends on the supplier. There are various suppliers from Laboratory suppliers around the world.
Sodium hydroxide as a diluted solution to adjust pH dissociates in the formula to the hydroxide ion to adjust pH only. It is NOT caustic soda when in solution to buffer the pH. Yes it is perfectly safe to put on your face. Most cosmetics are adjusted with pH in a similar way.
Hi Sya, you should get about 3 years from this product - if you change the materials used remember to check shelf life for a revised expiry date if needed.
Hi Rocio, it won't give the same viscosity or stability at that input, so xanthan is a better gum to use for its stability enhancing benefits. If you use guar, you will need to use more to support the viscosity and stability, so with a couple of trials you will find the right amount to use. I hope this helps, Belinda
Hi Rocio, it will alter the viscosity and stability to use guar; so you'd need to check your sample for suitability, it is not a simple 'swap' situation. Hope this helps, if you want to learn more, then please study our Certificate in Advanced Cosmetic Science or Diploma of Personal Care Formulation for full gum selection and details. Happy formulating!
No - it wouldn't be viscous enough. You need a waxy emulsifier to build viscosity. You will find this workshop useful: Can I use a different emulsifier: personalcarescience.com.au/Workshops/Emulsifierworkshop-3165/
Hey Belinda what is the percentage of emulsifying wax in a formulation like for water you said it's 76% of the total formulation Also kindly what percentage of preservative is recommend

Hi Belinda, can I add 10% Shea butter instead of water. Second question, on recipe on video there is no emulsifying wax. what percent do you use in this formula. Thanks
Yes there is emulsifying wax in there, and the full % can be found in the formula.

Antioxidants only protect against oxidation - so they are only necessary when you have ingredients that have a risk of oxidising e.g. plant oils or essential oils. Antioxidants usually act as a FOOD SOURCE for micro-organisms, so broad spectrum preservation is always necessary when your formula contains water. Please watch this video on preservatives: th-cam.com/video/0pnEdg6ZaAU/w-d-xo.html and I have a vitamin E video coming out on 7th June and it explains antioxidant input and selection, so please subscribe so that you are notified when this video comes out.

Such an informative video. Thanks. U added NAOH, won't it heat up the lotion temperature mam?
No - it’s a diluted form for pH adjustment only - it is not adding straight NaOH like in saponification
Hi. Could you tell me what the dilution rate is for the sodium hydroxide please?
We suggest beginners starts with a 10% dilution; when you are a bit more used to pH adjustments you could use a 30% solution. Hope this helps! You can also watch more detail here: th-cam.com/video/s0I7ZsGqUhk/w-d-xo.html and here: th-cam.com/video/kwvLAK3KauM/w-d-xo.html I hope that helps :)

Are you using caustic soda to lower the pH? is it safe to put on your face?

is glycerin used as emulsifier ?
Hi Areej, no, glycerin is a humectant, it does not have emulsifying properties. The waxes are the emulsifying materials. Happy formulating!
ok .. thank you .. you are very kind for replying me comment
as the lotion is at this runny stage can we bottle it before it sets up? if we are using a pump bottle.
You can but just make sure it is at room temperature before bottling to avoid a condensation layer of free water forming on top. Happy formulating!
Any substitute for olivem 1000
