Description

Brief overview

Soap noodles are produced by saponifying vegetable oils such as palm oil, coconut oil or olive oil, and/or animal fat (tallow) using sodium hydroxide. Soap noodles are considered to be the basic precursors of soap.

Both soap makers and hobbyists use soap noodles because it can be easily customized with pigments, fragrances and other additives to produce soap. This soap can be further customized by molding, pressing and stamping to provide the final product.

Different specifications of soap noodles can be used to make various types of soap, for example, toilet soap, laundry soap, translucent soap, high-lather, medicated and so on. 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. Trade Asia sources provide soap noodles to the world, providing you with the best products and best prices for your industrial needs.

Manufacturing Process

Saponification of Oil/Fat

Direct saponification is the most common method used to make soaps, where triglyceride molecules react with sodium hydroxide by the reaction.

Neutralization of fatty acids

Fats and oils are hydrolyzed into their constituent fatty acids and glycerol. The fatty acids are then neutralized with sodium hydroxide.

Saponification of fatty methyl esters

The oil/fat is trans-esterified with methanol to produce methyl esters. The methyl ester was then saponified with sodium hydroxide to produce soap with methanol as a by-product.
