Well I didn’t learn how to make soap but I sure had an awesome chemistry lesson. Thanks girlie!
😅😅😅
Shave them pits, freak!!
Wow. I watched a video of men making soap with baking soda and olive oil and boiling it.
Everyone in the comments said that the narrator made a mistake and meant lye. I'm glad to see it's actually a thing!
Yup, I watched that one too and was skeptical of their results. Overall, I'd say it doesn't really work in a sense that you can't make a bar of soap with this method, but I've used this soap slurry to make a spray for my plants (to keep aphids off). It totally works for that purpose!!!
I'm pretty sure this is more gentle than what I grew up making from my Grammie.
Lard and ash water.
Very interesting to learn the science.
I just made lye soap from ash water and renderings as a kid.
I like how you laugh and smile teaching this video, you make it fun. 😊
If you use NaOH, a golden rule of thumb is (quotas / proportions per weight): 1 NaOH / 3 H2O / 5 Olive Oil. Caution: Start adding and stirring NaOH to water... Then WAIT it gets cool, because it HEATS UP! ... Then mix this with Olive Oil... Be PATIENT... As by stirring temp starts building up... If it gets too slow... You can heat... but A LITTLE BIT! If you heat MORE than what... Then... You will LOSE control of the reaction... If i.e. you heat to 60 C... Then it will raise heat... To ...BOILING POINT... (Yes... like a ...volcano! lol)... The SECRET in all this... is NOT to allow it boil... or overheat... If so... You will produced at end not soap... but ...washing powder!!! (No joke! lol...) Then... it is "ready" if by stirring it starts getting "thick"... You leave it overnight... Or what... and then... Once it cools... You can use gloves... to rub... balls... soap balls... Letting them dry on a shelf... Allow a month before using! ... So it is by no means any longer caustic! ... TIP: use HERBS / boil herbs you like... (camomile, daphne..., rosemarinum etc in the WATER that you will use in your recipe...)... It is said that camomile is a fast thickening and hardening agent... Playing some the role of catalyst! Good luck! ...
Awesome info! Thanks for sharing.
Fantastic knowledge thanks!! I've seen soap volcano in hot process one time and she had to stir like crazy to get the temperature to go down so it wouldn't overflow from the pot! Haha!
Arrow root also is a thinking agent
Idk what you do for work but you sounds qualified enough that I'm gonna make sure to follow your advice
Thank you for sharing your knowledge!
I wished my college Chemistry professors were as happy as you are and smiling most of the time while explaining all these processes. I am a Chemistry Major and I enjoyed witching your video, keep up the good work.
😂😊
I wished I had you as my teacher when I was young. I totally flunked science because it was beyond boring. I went to has in Germany and basically just learned the tables. You made this experience fun and interactive. 🙂
Thank you so much!!! That means a lot
Thank you for making and sharing this video.
I love your video. Thanks for the experiment
Thank you! =)
This was super cool!
There are still middle eastern companies that make soap from olive oil and Bicarbonate of Soda in huge vats. Perhaps volume makes a difference. They talk in terms of 24 hours, not weeks or a month.
Whoa, that's really cool! Thanks for sharing. Would be interesting to do equilibrium concentration calculations for such conditions.
@@nadiakorovina9869 Check out CZcams videos on Nabulsi Soap made in Palestine. They've been making baking soda-olive oil soap the same way (up to 3 tons per day) for 2,000 years.
@@dalaillamathepctme6957 they're using caustic soda, not baking soda. That was a mistranslation. You'd have to use MASSIVE amounts of baking soda to generate enough hydroxide ions to saponify oil, let alone olive oil (which takes a ridiculously long time to saponify...). Baking soda is a very weak base, which is why it's safe to eat.
@@GabrielleduVent so if coconut oil was used could that make the process quicker? I just watched a video that said after quickly mixing soda/oil they lay it out on the floors for 2 days to harden, then slice into bricks, and then store for 40 days to cure. I just need measurements to test it
I found this very interesting thank you
You need a stick blender to make soap saponify. The oil has to emulsify with the caustic water. Im also not sure why you couldnt just stir the washing soda and the water to get it to dissolve. Im sure you have a reason, but in soap-making we stir the sodium hydroxide with the water before letting it sit to dissolve. Then we have to use a stick blender for 5-10 minutes after putting it in the oil, and up to 20 min if its just olive oil alone. Coconut oil saponifies much faster. A water discount helps. We usually use 36-40 percent sodium hydroxide to water, or between 1:2 and a 1:3 ratio. I might try this. I want to know if it could work!
Very interesting chemistry lesson. Thank you.
Hi, as a person just trying to learn the sciences, your videos help tremendously. Please make more videos. You are very talented. I would be grateful, as well as others too.
Love it thank you so much
You’re adorable! I’m excited to make soap!
This video is awesome! I was trying to find a video that uses baking soda instead of lye since a lot of people said the lye was harsh on the skin I wondered if perhaps baking soda would’ve caused less irritation, but really good video !
Thank you so much!!
Remember this is chemical reactions we are talking about so when you combine lye with oil it's isn't lye anymore, in fact it all gets consumed in the reaction to saponify the oil. If you are using properly made, properly cured soap...then there is no lye in the soap to blame for irritation. However it may just be too concentrated. Dilute more and rinse better.
Super cute!!!
Thank you =)
Actually, you can make Sodium hydroxide from baking soda, but it requires MUCH higher temperatures, over 800°C. It makes Na2O (Sodium-oxide) which you have to hydrolize with water and the reaction is very exothermic, it can cause the water to boil. So generally it's much easier and safer to just buy NaOH directly. Btw the video was good and funny.
Great info! Thanks for sharing. Yea, I totally agree.
What’s 800c ?
Nice idea. Can you share the reference of how bicarbonate can be converted to sodium oxide.
@@dr.faazilchemistry First it breaks down to Na2CO3 in the following equation:
2 NaHCO3 = 2 Na2CO3 + H2O + CO2
And then a calcination reaction takes place as shown here:
Na2CO3 = Na2O + CO2
I assume the temperature must be around a 1000 °C, because this occurs above the melting point of Na2CO3, which is 850 °C.
Just use electrolysis to make caustic soda.
If you were my friend I'd be over there taking notes and trying out samples. I made a coconut and baking soda scrub.
If you add 40 percent Laurel berry oil to the mixture you could make Aleppo soap. It is cooked for 3 days and has a cure time of 4 weeks. If you use sodium hydroxide the cure time is 6 to 9 months. It's a wonderful soap.
What’s 40 percent
@@rameikabentley9268 40 percent of your soap recipe needs to be laurel berry oil to make this soap actually work. You can figure out percents, right? You were on the right track. Just need certain ingredients and alot more cooking time to make this work. 3 days in a crock pot. Pour into a mold and allow to cure for 4 weeks.
Very nice and real video, please never change that real type.
That starbucks joke was pretty funny tbh
Lolll thank you =)
น่าทานมากก ถ้ามีโอกาสอยากให้พี่ฟานทำข้าวผัดเบคอนใส่แม๊กกี้ค่ะ ขอบคุณค่ะ
I think had you used a small amount of boiling water to dissolve the washing soda then cooked the mixture without the double boiler you’d have better luck. Oil and water don’t mix so you need to cook off as much water as possible before adding the oil. By using a pan of water to cook it you’ll never get enough water off if it die the steam that’s produced. I believe you could dissolve the washing soda in 2 tablespoons of boiling water at the start. Then you’d set yourself up closer to success but you’ll still need to cook off the water by just putting the mixture in a very shallow pan heated on low and continuous stirring. You could also pick up a box of washing soda for a couple of bucks at Walmart as a short cut around the problem with water. There’s not enough heat from a double boiler and stirring in this world that’s going to mix water and oil or oil and water. Then you should have no problems at all with it mixing into the olive oil. I’d love to know if you try it and how you make out with it.
Does the type of oil make a difference, as in the type of olive oil? Like virgin olive oil or extra virgin olive oil or ?
I do occasionally make soap. May I suggest that if you try this again that you use a different oil such as coconut oil or palm oil (sustainable please) as they saponify faster than olive oil. It may mean a week or two less heating and stirring 😁
When boiling. Just use direct heat on an stainless steel pot n lower the heat such that it boils gently.
Thanks for the tip!
Cool video. I wonder if you let the sodium carbonate dissolve and then cook it down for longer, letting the water evaporate, if it would concentrate more and actually work? Seems like a fun experiment thanks for making this!
Thanks for sharing
The edit ❤ jajaja love this
Idk what other content you create
But after the basic comment
😆😆💜😆😆
Subscribed✔️✔️
Lololol glad you appreciated the basic comment. I'll be sure to work in some science humor in my next vids =D
Wonder what would have happened if you’d used an immersion blender to mix.
Thank you so much for the demonstration! I was thinking about this... Well, I'll stick to sodium hydroxyde 😉
Thank you! =) I recently bought some sodium hydroxide from a hardware store, and hoping to make a video comparing NaOH and NaHCO3 as a base for soap making.
Are you serious I thought you were actually making soap !
I thought it was gonna work too =((((
I guess if it lathers, then it is soap.
I'm bit lost after watching your video as I was planning to make a home made olive oil soap! May be I will just skip and use the olive oil on my salad!😋😋😋
Dont give up making your own olive oil soap. is very easy to do at home. But you do need to buy some sodium hydroxide. Also easy on the internet. Also watch a few soap making videos many will give you a recipe that you can use. I have a few on my Chanel that might help. But their are many more better than me. Good luck and happy soaping. 🧼
@@catsmother4556 So nice of you to make an attempt to help to bring back my interest! 😊 I will surely check yours and other videos as I never tried an home made soap in my life! Thanks again and take care 😊😊
@@jais7009 Happy to help it is no where as complicated as some videos make it look. I made soap for the first time a couple of years ago it is so easy And lovely to use. I haven’t bought soap since. For a basic olive oil soap I suggest start with
500 grams light olive oil
64 grams sodium hydroxide often called lye. It comes as Cristal that look like sea salt.
190 grams water
Plastic / rubber gloves and a mask your covid mask is just fine.
You can use a washed out cardboard milk or juice box as a mould cut the top open.
or any silicone moulds you might have for baking are perfect.
Again good luck and have fun. 🧼
@@catsmother4556 many thanks again for the detailed information and your time mam! I'm surely trying this and will let you know in few weeks! Stay safe and happy times ahead 😊😊
👍🧼👍
thank you, can i use washing soda directly? I always wonder why they are two separate products. now I know
Yup, washing soda directly will product the same effect. Lye would be best, but it's quite caustic, so you'd have to be very careful with it and only add a proper amount.
@@nadiakorovina9869 Thank you Nadina. I think it could work pouring washing soda directly into warm oil, not diluted
@@PaolaDiMaio I think you would need a bit of water, because the overall reaction is still hydroxide attacking the carboxylate carbon of the oils, and you would make the hydroxide when washing soda reacts with water first. Would love to hear how your experiment turns out!
is it usable as a liquid soap? like for hand washing.
Unfortunately there is still a lot of unreacted oil and it feels kind of oily and not soapy. =\
@nadiakorovina9869 you probably added too much oil to the mix. It is VERY specific for making soap and the saponification process. Too little fats, and you will burn yourself on the unconverted "base/lye" and too much fat and it will not convert all of it, and oils will remain, usually called super fats.
Somehow you would need to do the math to figure out how much of the mock lye you end up with, and at what concentration, inorder to calculate how much oil to mix it with... and a belnder makes the emulsion process go way faster and easier.
I've also seen people talk about the properties in the chemical "oxyclean" being used to create a lye reaction.
Would the sodium bicarbonate become sodium carbonate in the stirring and heating process, thereby eliminating the need to cook it ahead of time? Btw, there is a Palestinian soap company, Nablis, that has a vid here. They say they "cook" baking soda and olive oil for 48 hours.
What's a good ingredient to add to glycerin based liquid soap to make it more sudsy?
Hmm, probably more fatty chain carboxylates. Essentially fatty acids reacted with hydroxides.
This is so cool though
Beautiful
Great video and cute accent! 😊
Thank you for doing the experiment and sharing. I’ll just buy soap to save myself worries & protect my cat. Lol
I have washing soda. I could just use that, right?
How did u mix water and oil
very interesting video
But in palestine they use baking soda not sodium hydroxyde how does it works ? You can see them in youtube videos just type palestine olive soap
That's super interesting! I'd love to look into that more! Please share any links you have for that.
Hot water
@@igerare3745 elaborate please
@@nadiakorovina9869 here it is, sorry didn't see your reply czcams.com/video/yPsYOnGPOZk/video.html
I love how humble you're!
Can't it be made via a cold process? Instead of heating, add the oil, sodium carbonate, and fragrance and then chill overnight?
Love the shirt.
Thank you =)
What if we use less amount of caustic soda than it requires..will it work?
No... product will be oily and soft.
It does work but if you don’t do it right you won’t get the desired effect. I make this a lot. There’s some videos on how the Middle East makes the olive oil soap with only these three ingredients
500er
Hi, thanks for the video but you are mistaken. Nablus soap is made with those exact same ingredients. I'm wondering if the ratio of ingredients is correct and have a suspicion that the cooking temperature is far too low. Having said this, I am not a chemist
That's very interesting!! Thanks so much for the info. I tried adding a lot more washing soda, and did not observe much of an improvement unfortunately. Hmm, do you mean the temperature of the cooking of the baking soda?
In terms of temperature of the cooking of the soap itself, it would be limited to the temperature of the boiling point of water.
@@nadiakorovina9869 no, nablus soap is made with NaOH. Someone mistranslated it (it originally said caustic soda). Its what soapmakers call Castile soap in terms of ingredients.
potassium hydroxide is usually used. would calcium hydroxide do with making soap? mygreathanks and blessings
She reminds me of Jessica hyde. Nice video :)
Thanks so much! =)
Nablus Soap Company makes soap in this way but it is cooked for 3 days.
If my olive oil of very high quality is now 3 years old, would it be any dangerous to use it for soap making?
safe to use
Naw, it's actually traditional to use nasty fats like spoiled lard and rancid oil so it don't go to waste.
Thanks
😁😁😁😁 thank you
Would a pressure cooker work?
Hmm, I have not tried it. I'm kind of hesitant to use those. They seem a bit dangerous. =[]
thanks
🤩
How gram of oil?
Why not just use Washing Soda if that is what you are trying to make before making the soap?
Great point! I only had baking soda at home.
Soo cute
One question, when using sodium carbonate, won't mixing it with water produce enough sodium hydroxide? Also I have been working on a similar project but my results aren't up to my expectations yet. Is there any way I could discuss this project of mine with yours. Thank you and have a nice day
Shounak, it's true that sodium carbonate makes a small amount of sodium hydroxide when dissolved in water, however, the equilibrium constant for that reaction is VERY small. So most of the sodium carbonate stays intact as sodium carbonate when dissolved in water.
This was such a thorough explanation of why you should use lye. Thank you so much!!
Haha exactly! Thanks for your comment =)
How gram baking soda?
Wait you guys don’t have lithium methoxide at home?
Lol, you'd be surprised at what you can find at the hardware stores.
Okay I’ll find another video. If they do it in Nablus it can be done.
Ca we cook the bs in the microwave?whats the quantity?
I used sodium hydroxide and pottasium hydroxide for that.
Yup, those work a lot better. Just have to be careful with proportions.
@@nadiakorovina9869 what are the proportions?
Please change the title of this video. Because at the end of it the soap is not successfully made, its just a un-usable liquid.
Good 👍
She is funny as well. Good 👍
I thought I'd heard that heating baking soda can release harmful fumes. If not that i know touching it after heating barehanded can be bad
Starbucks and leggings are pretty basic! That cracked me up lol
Thank you =D
My olive oil is a green color? That may make difference.
Go for other subscribers . Watched your channel. Like it. Love from Pakistan
I will buy from the store
Can you use lye instead of the baking soda or no
Lye actually works way better! We just couldn't mail lye to our students, but it definitely works and works a lot better. I'll probably make a video comparing soap making with lye and baking soda.
This is how soap producers make their soap in Palestine. It works for them somehow using just olive oil, baking soda and water. That’s how they’ve made soap for over a hundred years.
Can you bring the water to a temperature where you could super-saturate the sodium carbonate (heated sodium bicarb)? What if you started from sodium carbonate right off the bat? Would that help? I’d like to make my own soap as a stain pre-treatment and I don’t want to mess around with lye but I certainly don’t have the patience or the the time to heat something up over and over for weeks. Is there something in between sodium carbonate and lye?
Soap usually is measured out by weight. Perhaps it didn't work because ratio was not exact. It's very picky.
Isn’t this called liquid soap?
I think liquid soap is made with potassium cation rather than a sodium cation. The issue with the stuff I made is that there aren't enough hydroxide ions to convert all of the oil into oleate. =(
If you have lye, use lye.
Where's part 2? Show the bubbles 🧼 😅
Phew!
Dude, you’re hilarious
Sodium bikarbonat as sodium carbonat
I think the title should be how you can’t make soap using baking soda and olive oil.
You look like the Mythbusters girl (that's a good thing)
Thanks =)
1:2
2:4
Can you write ingrediant please
The best soap made from baking soda for cleaning dishes is not made from olive oil or even lard. My daddy said the best thing to mix with baking soda is elbow grease! Just sprinkle baking soda on pots and pans, especially glass baking, dishes, and rub real hard!!😂
Make lye water
No lye?
This video should have title "An ATTEMPT to make soap..."... It will be a blooper to watch this video.
Watch the video of how they make this in the west bank.
Turns out i just needed an Eastern European woman to explain it to me to understand.
Ohh, ok, so you're cooking soap like in Palestine for the last few thousand years❤!❤ Cool!!! My Grammie taught me that way as well.
It takes longer to cook than with ash water, it takes longer to set a d stable itself. It REALLY is so soft and gentle though. Making soap the long way is worth it in my opinion. Just for it's kindness to the skin or clothes and house cleaning.
I've been making it the Palestinian way since about 1978, though that isn't how my kin taught ne.
I learned it from neighbors, very happy to have learned so after all these years. 😊❤😊
Thanks for sharing, can you confirm you start with regular old baking soda using the method employed in Palestine?
