Laundry Soap Noodles
Toilet soap noodles is a soap noodle derivative created from saponification of oils and fats. Toilet soap noodle is a type of soap noodles that specialize in producing personal care products. The largest sources of soap noodles are Malaysia and Indonesia (mainly from palm oil). Other countries of origin include India, Brazil, Southern Europe, China, and the Middle East.
There are several manufacturing methods to produce soap noodles on an industrial scale: hot and cold methods.
Hot method involves the saponification of palm oil and fatty acids. A boiler is used to melt the saponification product by reaching its melting point. The product of saponification is the breakdown of triglycerides into fatty acid chains and glycerine. As the heat from the boiler ensures the temperature is at the melting point of the mixture. The newly melted soap noodles are molded into small portions by using a noodle-mould.
Cold methods utilize the mixing of palm oil with fatty acids under high heat. The palm oil is heated to the melting point before being mixed. In this method, no chemical preservatives are added and the newly formed soap noodles are molded 5 weeks after processing. The cold method is used to fabricate hand crafted soaps.
Laundry soap noodles are produced from lower grades of palm oil with lower oil content. Furthermore, laundry soap noodles are fabricated with the addition of fillers such as sodium silicate and kaolin. Hardness of the soap is affected by the amount of fillers added.
The percentage of TFM represents the amount of fat matter in the soap. The fat matter signifies the hardness and the quality of the soap. As total fat matter decreases in percentage, the soap is less capable of hydrating and is more harmful to the skin.
Toilet Soap Noodles - Application
Laundry soap noodles are the base raw material for the manufacturing of soap bars used in household applications. Laundry soap noodles are used mainly in cleaning applications. The cleaning process of clothing and other apparels utilize laundry soap noodles instead of toilet soap noodles due to the hardness and low TFM.
