How do you make slime using soap?

Answer 1

Soap noodles are essentially already soap, which has been shredded or ground and pushed through an extruder dye and cut into "noodles".

The soap noodles need only to be reheated with a bit of liquid added to facilitate the melting of it. Once the mixture resembles thick mashed potatoes, you would add fragrance, colour, botanicals, etc, and then scoop the mix into a mold (either lined wooden mold, silicone, heavy plastic, etc)

Once the soap mixture has cooled completely, it can be unmolded and it is ready to use immediately. There is no curing required for soap noodles, however, depending on how much liquid was added to melt the noodles, you may want to let the soap sit to further evaporate any excess liquid.

Answer 2

i recommend buying it.

But if you insist...soap is made by reacting fatty acids with hydroxides. The standard hydroxide is lye, but potassium hydroxide works too. There are quite a few difficulties here...start with the fact lye is the most dangerous chemical you'll find in the home. If you use too much lye the soap will be very harsh. There's an old TV show The Beverly Hillbillies about a family of...well, hillbillies...who found oil on their land and made enough from selling the mineral rights to buy a huge mansion in California. One of the running jokes on that show was Granny's caustic soap...which got that way because Granny used way too much lye in it. So...between the danger of the chemicals, the possibility of making soap that'll strip paint off the bathtub and the low price of factory made soap, it's not worth making.

It's really easy to make soap out of vegetable glycerin. Here's an article that gives you really good step by step instructions:

Answer 4

Making soap at home is a relatively simple process. The soap starts with a base of glycerin or lye and ingredients are added depending on the use of the soap and for scent. Common additives are oatmeal, mint, lavender, rose, and citrus.

Answer 5

Firstly, let us go through the structure of a soap molecule. Essentially, all a soap molecule is is a long chain fatty acid tail with a hydroxy group at the head. This enables the soap to interact strongly with non-polar molecules (e.g, most dirt and fat molecules), and with polar molecules as well (water). The colours and aromas are added during the industrial process.

We can make soap through a saponification reaction. If you have done some chemistry before, you might be able to recognize this reaction as esterification in reverse. What we will do is take an oil and react it with NaOH, giving us the original alcohol and carboxylic acid. You may be questioning this method, but if we go through the following reaction it might make more sense:

Triglycerol + NaOH ----> glycerine + soap molecule

In this sense, the fat can be anything - when i was back at school we used olive oil, and reacted it with NaOH, giving us the glycerol and the soap. Upon forming this, we can further add some NaCl, which will increase the precipitation rate of the salt - this step is known as "salting out" the soap, by adding an excess of Na+ ions.

A few things to be cautious of! Be very careful that you wash off all the excess NaOH. NaOH is one of the strongest bases and even in small concentrations can cause corrosion of your skin. It is not a pleasant experience - one of my friends actually used this soap that we made to wash his hands, and didn't thoroughly wash off enough of the NaOH. As a result, for the next couple of days he had the epidermis of his skin peeling off and it was quite an unpleasant sensation - therefore, if you plan on doing this yourself at home, be very careful!

In industry, the glycerol can also be reused. Therefore, it is important to save the gycerol if possible! It's used in making all sorts of things including lollies, plastics and explosives, making it quite essential to get the glycerol back in a large-scale reaction.

Answer 6

Back in the old days, you could make it from a mixture of ash and animal fat. Today, it's a lot more convenient to buy it at the store. Basically, soap is a long chain of a molecule with one end that acts like a non-polar hydrocarbon and another end that has a metal atom attached to it. The non-polar hydrocarbon end is "hydrophobic," meaning it doesn't like water (which is polar) and therefore repels it. But it does like greasy stuff, which is also non-polar. The end with the metal atom (usually sodium or potassium) makes that end of the soap molecule act like a salt, which is ionic and therefore polar. Water is polar, too, and so that part of the molecule is "hydrophilic," meaning it likes water very much. This allows the soap molecule to "bridge the gap" between polar water and greasy non-polar yucky stuff that's on your hands. So the water can surround the grease using soap as a medium, and washes it right off.

Answer 7

Just mix soap and put it in the freezer for 30 minutes or more and you get slime!

Answer 8

It is called saponification - the hydrolysis of triglycerides to remove fatty acids and glycerol.

Answer 9

Melt glycerine and pour on wax paper. when dry remove wax paper. I put in a small tin and carry them in my purse..
