To make Machine-made/hand-crafted soap, Sodium Hydroxide and animal/vegetable fat are mixed together to form the soap lye and then adding some essential oils/fragrances this mixture can finally be poured into the soap dye and cut into pieces. Watch the Videos to learn the complete process of making soap bars using Lye and Fat.
Animal Fat Soap Making:
Animal or vegetable fat reacts with sodium hydroxide, a caustic substance to create SOAP. They add water to mix it all up and encourage the chemical reaction. The soap settle at the bottom of the cattle. Now they spray hot liquid soap onto a big metal role and a big blade scrapes head of the role creating ribbons of the soap. This ribbons follow all the way to the next floor, two big steel rollers mix and compress the soap.
It pushes the soap to an extruder called a Noodle plate, that shapes it into soap noodles. As the noodles far from the extruder, which are then dumped into a mixer. At this point they add color in powder in liquid form.
Steel blades tear it up until the color coats the soap noodles. They add some fragrant oils and the blades toss it all together. When the batch is ready, a trap door opens, nudging the soap, then it’s forced to another needle plate. Next they push the soap to a Forming plate making a long bar. Drains mounted on a track slice it into shorter pieces called slugs.
The soap slugs are on their way to the next stage into a dye Press. The mechanical arm pushes the slugs through an oval plate, trimming it and then loading it into the dye. The dye rotates to accept the slugs. Mechanical presses move into shape and stamp them. Mechanical arms suction the bars to remove them from the dye. These mechanical pushers help may nudge the soap bars towards the suctioning arms.
The soap bars now travel through a wrapping station, delayed cramps and heat feels the plastic wrap in one fell swoop. Then automated creepers grab their apt bars and load them into a machine which slides them into little boxes. Now it’s time to pack it in and scrub up with the soap of your choice.
Vegetable Fat Soap:
It all starts with ordinary Olive oil and hydrogenated canola oil. It first has to be melted in these large stainless steel tanks. Getting the correct ratio for each ingredient is critical. So as each ingredient is added to the mix for saponification. The final ingredient made from sodium hydroxide or caustic soda as it’s more commonly known. This isn’t the kind of store you want to get on exposed skin. So protective clothing is the must.
Although the technique give producing handmade soap hasn’t changed much over the years today process is a little easier and for today’s soap makers that’s good news. Meanwhile being final purely cosmetic ingredients are being added to this new batch in this case and natural fragrance together with the second color to get the soap will attract its will decide just from start to finish the entire process has taken a little under 30 minutes and that’s how you make Handmade soap.
1. Weigh out your liquid and lye. Add the lye to the water and stir until combined.
2. Weigh out the oils, place in a stainless steel pot and melt.
3. When the oils reach about 90 – 95 degrees F. and the lye cools to about the same temperature they can be combined.
4. Pour the lye solution slowly into the oils and stir with a whisk to combine.
5. When the mixture become thick and opaque, it will be ready to mold. This thickening is called tracing and can be anywhere from 5 minutes to days depending on your ingredients.
6. Once the mixture is traced, pour it into the mold and cover with a blanket.
7. Leave it to rest for the next 24 hours. It will heat up and then cool down. Once it is cool, you can unmold the soap.
8. Cut the soap into bars and let the bars cure for 4 to 6 weeks. Until the cure time is over, the soap will be very harsh. The longer you let the soap cure, the gentler the soap will be.
You can also make soap from glycerin; you get clear bars rather than opaque ones that result from animal fat.
