For us to be able to fully understand on how to make soap from soap noodles or in other word how to make bar soap, we need to first of all know what is noodles. Noodles are the raw materials used mainly in the making of soaps and they comprise of Fatty Acids from both animal and vegetables. Sodium hydroxide is used to convert these oils to a salt of the fatty acids.
Soap manufacturers use noodles, their preferred fragrance and pigments to manufacture their unique brands of soaps. Different noodles are used to manufacture different types of soaps. In developing countries, cheaper noodles are used to produce affordable soaps.
Most noodles are mainly produced and exported from Malaysia and Indonesia. Other noodles facilities can also be found in countries where palm and coconut plantations are found. In India the noodles are mainly made from palm stearin and palm fatty acid distillates. On the other hand, noodles from China are made from palm oil and animal fats.
In this review we will try to guide on How to Make Soap . We will cover at least three methods which can be used to make soap from noodles. These methods include the following:
Since its discovery in 1779, glycerine, also known as glycerin or glycerol, has been used extensively in
pharmaceuticals and cosmetics. It has a wide variety of uses, including being an antimicrobial preservative, solvent, emollient, humectant and sweetener.
It is environmentally safe and occurs naturally in animal and vegetable fats and oils, many of which are consumed as part of a normal diet. The glycerine that is used in topical products can be produced synthetically or from vegetable sources, but is most commonly produced as a by-product of
the meat industry.
Prior to use in topical products, glycerin is purified, with most manufacturers of topical medicines using pharmacopeia grade glycerine.
Glycerin occurs naturally in the skin and comes from the circulation, the breakdown of sebum triglycerides and topical application. Changes in skin hydration have been shown to correlate with
Glycerin has a significant role in cell proliferation, skin hydration, skin elasticity, barrier recovery and lipid synthesis, while also playing a role in wound healing.

What are the soap noodles uses ?
The soap noodles uses are:
- to manufacture toilet soap bars or bath soaps
- to manufacture laundry soap bars
- to manufacture Bath or Shower Gel or Cream
- to manufacture translucent soaps
At the manufacturing plant soap noodles are added with fragrance, pigments and many other components their own specifications of soaps. The simplified process enable manufacturers to make variety of soaps with different fragrances and features.
Bar Soap Production : Re-batching
This is a soap making method which involves grinding of soap bars. Milk or water is then added to the ground bar soap and then the mixture is blended again.
Melt and Pour
In this process of bar soap production, pre-made, un-scented and un-colored blocks of soap are used. A boiler or microwave is used to melt the blocks of bar soap. Once the soap has melted fully, add your preferred fragrance and color. The soap is then molded and is ready for use as soon as it has cooled and hardened.
The following items are required in order to make soap from this method:
- A clean working space or counter with either a double boiler or microwave.
- Spoons or whisks.
- Measuring spoons.
- Soap pour and melt base.
- Preferred fragrance, color or additives.
- Heat-resistant bowls.
- Containers to mold the soap in.
All soap making processes have their advantages and disadvantages and this process is not any special. The following are the pros and cons of melt and pour soap making process.
This process of bar soap production entails boiling the oils in the soap to close to 100 degrees. Once the oils have boiled, add the lye and water mixture slowly until you achieve a thick texture. Start adding your preferred fragrance, color and additives once the mixture has achieved trace. Your soap will harden after 24 hours and take close to four months to fully cure and be ready for use.
– Vegetable oils or animal fats,
– Fragrance and preferred additives,
– A cool and dry place where the soap can cool and cure.
– A flat and clean working space.
– Natural or synthetic coloring.
Bar Soap Production
Bar Soap Production or making soap from noodles is easy since soap noodles are essentially soap. You only need to reheat the noodles using a liquid to facilitate its melting. Once the mixture has resembled mashed potatoes, you can add the color, fragrance or botanical and mold the mixture you have scooped.
Soap made from noodles can be used immediately it has cooled completely. Curing is not necessary but you may have to wait for the soap to sit for longer for the liquid to fully evaporate depending on the amount of liquid used.
Noodles are classified into the following categories depending on the type of soap they are used to manufacture. They include the following:
- Laundry soap noodles — used to manufacture laundry washing soap.
- Toilet soap noodles – this noodles are used in the manufacture of toilet soaps, bathing soaps and hand wash.
- Multipurpose soap noodles – Used in the manufacture of multipurpose soaps.
Laundry Noodles (LSN)
LSN are used to manufacture economic laundry soap. LSN is more economical compared to laundry noodles which is of a higher quality. Laundry soaps are manufactured using cheaper palm oils which also have a lower oil content compared to toilet soaps.
Sodium silicate and kaolin are used when manufacturing laundry soap noodles since they help add the hardness required in laundry soap noodles. This hardness is necessary when producing laundry bar soaps.
Multipurpose Noodle (MSN)
These are noodles used to manufacture multipurpose soap. Multipurpose soap is economical since it can be used for washing clothes and bathing instead of buying different soaps.
Toilet Noodles (TSN)
TSN are used to manufacture bathing soap and hand wash. TSN are more expensive compared to other noodles. This is mainly because they have higher oil content. TSN are off-white, snow-white or extra-white.
It is also possible to find translucent noodles being sold in the market. This translucency is not natural and it is achieved when soap molecules are forced to line in a way that allows the passage of light. This can be achieved when special or powerful finishing lines are used together with additives like sorbitol, glycerin or propylene glycol.
