The weather is just too hot!! HOT!! Plus me walking back home everyday with this HOT weather does not make me feel any better. I always..i mean ALWAYS come back home with dripping sweats. And that obviously does not make me feel any better. The first thing i do once im back home is SHOWER!! Standing under the cold pouring cold water screams HEAVEN=). I automatically feels refresh and relaxed!
Shower is never complete without the creamy, sweet scent, and honey toned shower cream. The creamy sweet smell never fails to make my busy day feels better. Have you ever wonder how shower creams are made of? Shower creams have almost the same making method of the soap. Oils and fats for soap are compounds of glycerin and a fatty acid. When oils are mixed with an alkali, they form glycerin and the sodium salt of the fatty acid. To make soap, we must break the fat into its fatty acid and glycerol constituents. The fatty acid has a long hydrocarbon tail which is soluble in fats, and a polar oxygen end which is soluble in water. Thus a fatty acid in solution acts as a soap by dissolving fats in one end of the molecule and water in the other. When we use a strong base, such as lye to break apart or hydrolyse the fat, the fatty acid is present as a large cation which is polar at one end and non-polar at the other. Just as we can have sodium chloride and sodium carbonate which are soluble in water, we can have sodium octanoate, the sodium salt of octanoic acid, which is also soluble in water.

Saponification is the term applied to the hydrolysis of fats using a strong alkali like lye. The reaction is [C15H31CO]3[C3H5O3](s) + 3 NaOH(aq) -----> 3 C15H31COONa(aq) + C3H5(OH)3(aq) fat(s) + 3 lye(aq) -----> 3 sodium palmitate(aq) + glycerol(aq)
While this reaction may appear intimidating because of the long formulas, it is, in fact, quite simple. It could be written generally as:
[RCO]3[C3H5O3](s) + 3 NaOH(aq) -----> 3 RCOONa(aq) + C3H5(OH)3(aq)
Where "R" is some long carbon hydrogen chain. If you look on a list of ingredients on a soap, you will find things like "sodium stearate," "sodium palmitate," or, generally, "sodium somebiglongnameate." This is simply specifying the particular fatty acids present in the soap.When fat is introduced to a soap solution, the non-polar tail of the fatty acids dissolves in the non-polar fat, leaving the water-soluble oxygen end at the surface of the fat globule. With enough soap, these fat globules become covered with a water-soluble coating and disperse throughout the solution, as in the last figure.
I never know making a soap bar needs to under go so many process. Well, atleast i know now what`s in my soap bar=)
hasha: shower is heaven.
