Our Soap Cleans Naturally
Soapmaking is the simple combination of an acid (oil) and a base (sodium hydroxide or lye, an alkali) to form a salt (soap). Saponification is the natural chemical reaction of soapmaking. When these two ingredients combine, and friction of stirring is added, all ingredients break down to their molecular forms and recombine to form a soap molecule. This new molecule is made from the molecules in the broken down fatty acids and base.
Saponification generally takes about 24-48 hours to complete once the sodium hydroxide and oils have been mixed and the raw soap has been poured into the mold. When saponification is complete, the lye and the oils are no longer lye and oils and thus are not present in their original form in the soap, they have come together to form a new molecular entity which is the finished soap.
Soap vs. Oil vs. Water
Afer the saponification is complete, the resulting soap molecule has a head and a tail. The soap head is hydrophilic (water loving) and the tail is hydrophobic (water repelling) in nature. As water is not able to penetrate grease or dirt. When grease or oil are mixed with soapy water, the soap molecules work as a "bridge" between the dirt and the water. The Soap molecule head is drawn to the water and the tail attaches to the dirt. In this way soap can remove dirt and wash it away.
