Hey tara, I thought that pH measured the concentration of either hydrogen ions or hydroxide ions in a solution. You said that distilled water likes to take on the pH of whatever you mix it in with, but shouldn't it be diluting the H+ or OH- ions in the solution? Shouldn't you have to take into consideration the amount of water you are diluting your cream or serum to get an accurate pH measurement? I just finished my college chemistry lab and these things are fresh in my mind, but I don't know too much about cosmetic chemistry and formulations, so I thought I would ask.
Yeah, this is what happens. It’ll adjust the pH up or down based on the initial product, so you’ll need a calculation to find out your initial product’s pH. I’m sure there are some online, but if you just did college chemistry, you should be familiar with ICE tables. For this sort of test, you have the change, equilibrium, and starting quantities of water and product, so you should be able to calculate your product’s proton concentration from it.
Hello! Very informative video. Definitely needed this. I am a little confused when you say you add 10% of product & 90% of water. How are you measuring this? There is no batch to measure for, so how are you measuring the 10%? Is it the the weight of the beaker?
Rather than 10% of the original batch, she’s referring to making a new solution that’s 10% product and 90% water. And these are percentages by weight, hence the scale.
I guess it mean putting a certain amount of product in to the point where when put in the water it will dissolve without having too much or too little.
Hey Tara ! I love your videos and you've taught me SO MUCH! I have questions for you. How do you measure the PH of sugar scrubs do you also mix them with water like in the video? Also my sugar scrubs are oil based however I can imagine water getting into them while used. Is It better for me to stick with Leucidal SF complete or Optiphen as a preservative? I could really used your help with figuring this out. Please respond whenever you can I would really appreciate it. Thank you again for all you've taught me!
Great video! I attempted to do this for a solid conditioner bar using 10% conditioner bar and 90% distilled water. The result ended up being similar to the cream consistency you show first in the video, before you diluted it. Any tips you recommend for conditioner bars?
Hello Tara. You are amazing! I learned so much from you about the sugar scrubs that I've always wanted to make and how exactly to measure the pH of the product. Just one questions - since most sugar scrubs have no water (we want to keep them that way, when and how do you measure the pH? Obviously i the process of creation but when? Is this pH meter measures in oil or even in a mixture of oils and sugars? Thank you again. Your videos are precious
when you make a batch of ur cosmetics do u check the ph level each time? or bc u know the recipe works do u only do it when u are formulating the recipe?
elise Yes, you must check the pH of each batch that you make for several reasons. First, the pH of your water may vary slightly, each time, due to the source or qualify of the purification methods used. The pH of your raw ingredients could vary slightly as well due to the age or degree of freshness. Slight errors in measurements can affect pH. The temperature of the room that was used at the time your batch was prepared can also vary pH. The same raw ingredient could be processed differently between manufacturers which can also cause pH levels to vary. All you have to do is check the ph of your final product and you’ll know whether it’s at 5.5 or not.
@Gio Marrocco Once you’ve made your cream, as a final step you’ll always need to add a few drops of a buffer solution, such as diluted citric acid to lower the pH, or diluted sodium hydroxide to raise the pH, to as close as 5.5 as you can. Go to RUclips or do a Google search for “How to adjust the pH of a _____ (cream, lotion, etc...) to learn how it’s done. Good luck!
Nice mam, Can u pls suggest how to make 10% citric acid solution for lower ph of vitamin c serum, is it citric acid 10 : 90 gm water mam. Pls advice mam, thank u in advance.
Hey there Tara!! It’s been a while!! Hope you’re doing good!! Woah, you’ve really grown on youtube!! Congrats💞 I took a break from YT but im back and i had to check you out! The quality of your videos is amazing!! But honestly your content’s getting more and more interesting! Loved this!
i know this is a dumb question but when testing the pH of a product i assume you add whatever you are using to adjust the pH directly into the product and then create the diluted solution with the newly adjusted product and figure out if you need to adjust it again from there correct? Also are you making about 1 ounce to test?
Hi. How do you clean the oily cream residue on the electrode? I don't think just the distilled water will clean it thoroughly. Won't it effect the ph reading of the next sample?
so before we pour the cream/serum/face wash into packaging bottle, we should measure the PH while the product is still inside the beaker right? do we have to add water inside the beaker or do we pour like small amount of our product in another small beaker like you did in this video? after that how do we adjust the actual ones inside the beaker ?
Does the manual of your pH meter instruct you to add water to measure the pH of creams? The reason I ask is I found the following quote online: “Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When a solution is diluted with water the pH of the solution will increase or decrease towards a neutral pH of 7.” If this is the case, won’t adding water to your cream give you inaccurate pH readings? I’ve seen a demo of an expensive Hanna pH meter where the probe was stirred directly into the cream without adding water. But I’m not prepared to pay $500 for such a meter. I need a accurate but economical pH meter designed to be used in creams of light to medium viscosity. I’m curious if there’s any mention of this in the owner’s manual of your meter.
@@KarenxPoulin Get a pH meter with a probe specifically designed to measure the pH of semi-solids such as yogurts or sauces. I got one, it works awesomely on emulsions without having to dilutes these with water. Go to MilwaukeeInstruments.com and search for “food pH meters”. 😉
You really should check the ph of you distilled water, some are not the perfect theoric 7. And no, the pH you are reading is not the pH of your cosmetic, you have to ajust it to your dilution ... You did a 1/10 dilution, so it would bring the pH of your solution 1 unit closer to 7 (being a log10 of concentration of H+ ions). The difference isn't huge, but it's still important, especially if you use pH dependant preservatives, or ahas etc Hope this helps !
Lets say you take out from your cream 2 grams (can be any quantity, less or more), that will make the 10%. Knowing this, you calculate how much means 90% water that you need to add.
you can, but they aren't as accurate. I think they are fine to use if you are just making a face wash, moisturizer, or serum. If you are formulating with things like AHA and Retinol or any other ingredients that need to be in a specific ph range then I recommend a ph meter.
How can I make my facial soap more acidic? I've already bought a facial cleanser but a lot of people say that it's more alkaline and I want to lower its pH. Could I?
It's doesn't matter the size of the test batch. As long as it is enough for the meter to test and is a 10% dilution. Typically the test solution most people make is 1g product and 9g distilled water.
When you are formulating a product, how do you figure out what the ph needs to be before adding the preservative? Do you add the preservative while formulating then change the ph after?
Hey Girl. Just wanted to answer in case she doesn’t see you comment soon. You can use Citric acid to lower it & sodium hydroxide to raise it. Check out her video on changing cosmetic PH for more info. Good luck.
Aleis Sanders np! I like to use Makingcosmetics.com for ordering my stabilizers and ingredients. They have everything and VERY detailed descriptions of products (ph, usage, odor, properties etc.)
Just watched a weed grower say that all those meters are essentially the same components and equally as good. The customer service and warranty is the difference. I notice on Amazon, a lot of things are obviously made in the same factory but be sold by different companies for different prices. I wonder if this is one of those times. They're using the same components. Edit. Okay saw your perks with the better meter. Is there a reason why you chose that brand vs the Apera I see a lot of people use? I'm just starting my PH meter research rabbit hole. I spent days just on beakers omg. I wish there wasn't so much cheap crap we have to sift thru to find quality built items. This throw away culture is really time consuming.
you want to keep your products around 5-6 since our skins PH is roughly around 5.5 Some products may need a lower ph. For example; products containing alpha hydroxy acids need a ph of around 3.5 - 4. There are some other ingredients as well that are only active in specific ph levels. So keep that in mind when you are choosing your ingredients for a product.
Why showing clearly the results of the big PH meter reader and hiding the results of the cheaper PH meter reader 😂😂😂😂😂. What an advertisement. Well paid for 😁😁😁😁😁😁😁
As I said in the video, I can’t show the results of the cheaper one because there is no hold button on it that keeps the ph reading from changing. So I’m not able to lift the ph meter out of the solution to show it. I literally explained this in the video. And actually this video just proved that the cheaper ph meter is a good and accurate ph meter that I recommend. The readings of each ph meter were very close to one another. Both ph meters are great and I recommend both of them. I just think the more expensive one is better for more experienced formulators who use ph meters often. This was not a paid advertisement. I bought this ph meter myself. If this was a paid advertisement there would have been a disclaimer saying so. it’s illegal to have a paid advertisement without disclosure.
@@TaraLeee some people always try to find a reason to complain. Your videos are very informative, super helpful, and accurate. Thank you for doing such a great job and helping us beginners to formulate our own scincare.
Just wondering, how would you know which one is truly accurate between the cheaper and the more expensive ph meter?
Yeah I was wondering that too. She's assuming the cheap one is wrong. Could be the other way around or both could be wrong
use liquid types ie API pH tester to compare it...
