CHAPTER ONE
1.0 INTRODUCTION
1.1 BACKGROUND
Soap
is the earliest detergent know to man and apparently was first made by
the Romans from animal fats and oil and wood ash which is an alkali that
contains potassium carbonate, sodium, potassium hydroxide called potash
leached from the wood ash (Robert, 1994). It is also an unsaturated
ester since an ester can be split into an alcohol and a carboxylic acid
by hydrolysis. Meaning that it does not contain all the solutes that
can be dissolve at a particular temperature (Kirt Othmer, 1994). Also
soap is a metallic salt of a fatty acid because if a metallic base is
used in the hydrolysis instead of water, the metallic salt of the
carboxylic acid is obtained, not the acid because carboxylic acid are
weak acid which dissociates only slightly in solution
(Hou, 1992).
1.2 Soap can be defined as the sodium or potassium salt of fatty
acids, made by heating fats and oil with caustic soda or caustic potash
respectively (Cook 1990).
Most soap was manufactured by an alkaline
hydrolysis reaction called the Saponification, which is the reaction of
fats and oil with alkali.
C3H5 (COOR)3 + 3KOH 3KOOCR + C3H5 (OH)
(where
R – represent the hydrocarbon chain) also according to the equation
above, soaps was made in huge keittes into which fat and oil and alkali
were piped and heated until it boils vigorously.
Saponification is
the process used in making soap since ancient times, soaps have been
made from vegetable and animal oil and fats looked in alkali (Kott,
NaoH) (Steiner, 1990). Soap and detergent are both cleaning agents and
both work in the same way, but soap cleanse with the natural occurring
materials such as animal fat and wood ash.
1.3 TYPES OF SOAP
In the world of soap
manufacturing, there are basically three types of soap, under them they
are classified according to their categories:
(1) Foreign Soap
These are soap that is medically investigated to cure a skin diseases. Examples:
(a) Medicated soap
i. Antiseptic soap
ii. Germicidic soap
iii. Herbal soap
(b) Tablets Soap
These are soap that is operated and purified, dyes and perfumed added, to make the skin mild.
Example: i. Toilet Soap
ii. Bar Soap
(c) Local Soap
These are meant for a purpose not medically investigated but meant for cleaning ability.
a. Black soap
b. Sida Soap.
But here we are basically on the one made from Local raw material, which is the black soap (Ncha Nkota).
1.4 AIM AND OBJECTIVES
I. AIM
Preparation of soap using local raw materials.
II. OBJECTIVES
1.
To prepare local soap with woodash derived from the calyx and the
corolla of palm flower (Ejeasis Guineensis), which serves as an alkali.
2. To know the trees in which caustic alkali can be obtained apart from palm tree (EleasisGuineensis).
3. To improve the properly preparation of local soap and high quality local soap.
4.
To educate some illiterate local soap producers on how to set a
standard in the production of local soap and still retain its
effectiveness and for a wider acceptability.
5. To create awareness on the need and importance of locally made soap analysis.
6.
To make known to or enlighten especially the local soap producers (both
urban and rural manufacturers) on the best and exact quantity or raw
materials and methods to use to achieve better results in their
products.
- This research project could as well as form basis for further research work on local soaps analysis in this institution.
1.5 STATEMENT OF PROBLEMS
The problems why
people are no longer interested in the local soap is because it causes
irritation of the skin; Reason, because they are not medically
investigated and are not dirtiness causes dust, grief and stiffs on
fabrics in the heading process becaus3 of the inaccurate measurement of
the alkali and inability to bring out the purest form of the alkali.
Also some smokes and wood particles enter into the pot of soap on
stirring because of inability to maintain a hygienic on cooking and on
stirring.
1.6 HYPOTHESIS
H1 : Raw Materials can be used in making local soaps
Ho : Raw materials can not be used in making local soap.
1.7 SIGNIFICANCE
This soap includes
“Builders” as alkaline compound, which improve the cleansing
efficiencies, example, in washing of cloth, washing of plate and washing
of kitchen utensils.
1.8 LIMITATION OF THESE STUDIES
This research
work is limited by the extraction of alkali to manufacture good quality
local soap with the leaching process and filtration method and it’s
cr6stallization.
