Coconut oil contains key chain fatty acids ( eg, lauric ) with 12 carbon materials form a chain . For soap making , the short carbon chain oils have better features . Palm stearing is a long carbon chain fatty acid with 18 carbon atoms in a chain .
So why soap is made from pure coconut oil than the other soaps ? The percentage of sodium ions mainly. Soap is a surface nullify the natural pressure of the water surface . The sodium ion adhesion molecules socks ' dirty ' in the cleaning process , so that water can flush out impurities . The rate of the chemical sodium soap containing 12 carbon ( lauric fatty acid ) is higher than the rate in the chemical sodium soap containing 18 carbon chains ( stearic fatty acids ) . Soap contains sodium ions will have better cleaning properties .
Benefits of the cooling process ?
- The soap factory scale use of palm oil and other vegetable oils and these oils must be refined oil ( RBD through the process ) and then boiled soap . This requires a high energy and a lot of expense .
- Coconut oil is extracted from fresh coconut good quality should not refined or boiled to produce a product of high quality soap . And this production process does not require energy .
- During the heating process , glycerin is often removed . Cooling process removes glycerin soap .
Why remove the glycerin soap ?
- Glycerin ( C3H8O3 formulas ) is a specialty solvents and soluble in water .
- So , glycerin soaps are useful in enhancing and cleansing properties .
- Glycerin is not affected by the hardness or salinity of the water , so it is " clean " in river water and brackish water .
- Glycerin good for the skin and helps prevent the " dry skin " and cracked .
