Soap analysis has become important due to the aim to streamline test techniques and so appropriately cater for the requirements included in soap to make it perform effectively. As opined by Oseni (2017) soaps are the sodium or potassium salts of long chain fatty acids and are made by saponifying fats and oils with alkalis such as potassium hydroxide. Lux soap, which is used for bathing and washing, must be devoid of disagreeable odors both as received and in water solution; it must not contain/have any active chlorine or oxygen. It should not include any apparent foreign stuff and should not have any active ingredients. Lathering and washing characteristics that are not harmful to the skin (Idowu 2020). It should also have a low water content, no contaminants, and a very minimal amount of extra alkali.
It is produced by the action of a hot caustic solution on tallow or fatty oils, with the concomitant creation of glycerol, which was formerly wasted or left in the soap, but is now recognized as an useful by product.The reaction is as follows:
3NaOH + (C17 H35 COO)3 C3H5 3 C17 H35 COONa +
Caustic Triglyceride sodium stearate
Alkali (soap)
C3H5(oH)3
Glycerol
Soap can also be made by the action of caustic soda or fatty acid without producing glycerol. The reaction is as follows:
NaOH + (C17H35 COO)3C3H5 3C17H35COONa + H2O
Caustic
Soda Stearic acid Soap Water
The NAFDAC STANDARD FOR QUALITY SOAP IS – 02 – 1526.
AIMS AND OBJECTIVES
The aims of this study are:
(i) To determine the moisture content of Lux
(ii) To determine the free caustic alkali
(iii) To know the quality and its durability
It is hoped that the results obtained in the analysis and its interpretation in terms of quality may culminate in suggestion that could lead to an enhancement of those characteristics of the soap.
1.2 STATEMENT OF THE PROBLEM
1. The soap (Lux) analysed shrink and become soft when it contains high moisture content.
2. The soap with high caustic alkali causes rashes and irritation irritating the skin.
3. When glycerol, which is the valuable by product of soap separate, it will constitute a problem.
1.3 HYPOTHESIS
Ho : Lux Soap sold in Nigeria markets have the NaOH content required of good soap.
H1 : Lux Soap sold in Nigerian markets do not have the NaOH content required of good soap.
1.4 SIGNIFICANCE OF THE STUDY
The product analysed will be used for washing and general removal of dirties. It will also enhance removal of germs and also reduce the surface tension. It will also serve to remove colour and greasy surfaces.
1.5 LIMITATIONS
In hard water, it is an ineffective cleaner. Hard water contains salt of Magnesium, calcium and iron in solution. When soap is used in hard water, calcium soap the insoluble calcium salt of the fatty acid and other precipitate are deposited as curds.
2R – C – O – Na+ + Ca2+ (R-C-O)2 Ca2+ curd.
