Experiment 4: Soaps and Detergents Background- laboratory preparation of detergents in water ,Experiment 4: Soaps and Detergents There is some evidence that soap-making was known to the Babylonians in 2800 BC and to the Phoenicians around 600 BC. Surprisingly enough, it seems that soap was first used for cleaning textile fibers such as wool and cotton in preparation for the dyeing process and not for personal hygiene. WoolPreparation of soap [detergents-post lab questions]DISCUSSION. This was done to produce soap in a laboratory by cooking oil, Sodium hydroxide, ethanol, and water. First of all, it should measure the 5g of Sodium hydroxide and 10ml of cooking oil. Then 20ml of water and 20ml of ethanol were measured and mixed together. The measured mixture was could be discovered by litmus papers.
