If your soap has cooled down, touch the microwaved soap and notice the texture. Is it the same as the bar of soap?
This is a big clue has to what is happening with the soap. This law explains that when a gas is heated, its volume expands. When soap is microwaved, the air trapped inside of the soap heats up and starts to expand. The water inside the soap also heats up and will turn to steam.
As the gases grow in volume, they push on the remaining soap ingredients, expanding the bar from something small and compact to a fluffy blob. This is also why the soap feels a bit drier. The water in the soap has turned to steam, and has been released from the soap. The same reaction you see with the soap happens when you make popcorn. Water inside of the kernel expands as the kernels are heated. Eventually, the water becomes hot enough that it turns to water vapor or steam.
As the steam expands, it pushes on outer walls of the kernel until they burst exposing the yummy insides for the popcorn kernel. I actually think the microwaved soap looks like a large piece of popcorn. There are a number of sensory activities that use crumbled ivory such as ghost mud. You can also use the soap like, soap. A few years ago, the makers of Ivory, Proctor and Gamble, shared documents from their archives that showed the process their chemists used to develop floating soap.
While a great story of a mistake leading a great invention, no worker accidently whipped more air into the soap. Mask Policy Update: Masks are required indoors for all visitors ages 2 and older.

Today we are sharing a great article about the uses of Ivory soap! We will also share the fascinating history behind this soap which I think is what makes it so unique. Of course, we will also be diving into some soap science which is really important to us on Chemistry Cachet.
We have shared posts like old-fashioned skincare tips that work and old-fashioned cleaning products that work amazing! Not only is the history so incredible behind vintage products, but the science is also amazing! I am amazed how there are many products we use today that were create in the s. These products continue to outshine many other products which goes to show good science-based items never go out of style.
Which brings us to Ivory Soap. Thank you for providing these for our post! There was an old black and white movie playing the other day, and in the movie, she was using a bar of Ivory soap. I know my grandmother loves Ivory soap and has talked about it many times. Then, I was scrolling through Pinterest the other day checking out vintage ads from the s and an Ivory soap ad popped up.
I have also been dealing with some pretty severe hand eczema, so I had a visit with my doctor. He told me to switch to a gentle bar soap like Ivory soap for hand washing. This is when I decided to do a post on Ivory soap! It just keeps popping up, and it has been a popular product since the s. According to this article from Jrank Science website , soap is the result of a chemical reaction between triglycerides and a base today this is typically lye.
This is called saponification where the triglycerides are broken down to fatty acids and neutralized into salts. This is what I love about vintage products…the history! It is amazing to me that a product created in the s is still in use today. You know it is a good product when it is still being manufactured and sold centuries later.
This was an important property to people back in this time period who bathed in rivers and lakes. If your soap fell, it would sink and you might never see it again.
But if your soap floated, you never had to worry! In , Harley Procter was thinking about this new soap. As he sat with his family in church one morning, he listened to the 45 th Psalm.
And this was the beginning of brand-named products as we know them today. Another fascinating part of Ivory soap history is the science on how it works. The soap machines were set to mix up a batch of soap much longer than the typical requirement, working so much air into the batter, it made the mixture lighter. This made the soap float! According to information found in James N. Gambles original lab notebook from the s, his notes show he actually invented floating soap over a decade before Ivory soap would launch.
James N. As we talked about above, soap is simply made from oil or fat with a caustic substance. What made Ivory soap so superior, was quality of ingredients along with the skill of how it is blended.
From the beginning, Ivory soap represented value. People knew when they purchased a bar of Ivory soap it would be good quality each time. The remaining eight raw materials used for Ivory must meet more than 20 raw material specifications.
The intermediate product, called base soap, contains more than sampling instructions listed in Manufacturing Standards, from every 30 minutes to once a month. At individual plants, the finished Ivory bar undergoes more than 25 lab examinations including odor, color, bar feel, density, and moisture plus product and wrapper appearance.
There are so many more things that go into the quality of Ivory, but the ones listed above really blew me away! Now that we know more about what makes Ivory soap so unique and interesting, here are some great ways you can start using it today!
These are ways I have tried out and enjoyed. It had so many neat ways to use Ivory soap. Please refer to this publication if you would like more details on some of our tips below. This is how I am using Ivory soap the most. With all the extensive hand washing I have been doing, my poor hands have eczema pretty bad. I had a visit with the doctor, he said to switch my hand soap to a simple bar soap like Ivory soap this is what inspired me to do this post today.
Anyways, it has been great to use it for hand washing. It is so gentle, but also gets hands clean. While this may sound a little too convenient, there are well documented cases of such happy accidents happening. For example, artificial sweetener was discovered because a researcher ate a sandwich after forgetting to wash his hand s; Super Glue was invented by accident, not once, but twice; the Slinky was originally supposed to be used as a tension spring in horsepower meters in battleships before the inventor accidentally knocked one off his desk… the list of famous accidental inventions goes on and on and on.
And as Ivory has insisted that that's how it happened for 12 decades or so, case closed right? Perhaps the first tip-off should have been the "unnamed employee. But the nail in the coffin came in , when this accidental floating soap origin story was officially debunked. I think we'll make all of our stock that way. But here's the weirdest part, the chemist who made that discovery was none other than James Gamble , the son of the man who co-founded the company, James Gamble Sr.
Yet, somehow, the fact that he invented one of the company's most famous and enduring products was forgotten about for over a century. Although Gamble discovered the process to make soap float way back in and seemingly had plans to "make all our stock that way", the idea was shelved for quite some time, further demonstrating that the eventual launch was purposeful, not accidental.
