This step is. In order to perform as detergents (surface-active agents), soaps and detergents must have certain chemical structures: their molecules must contain a hydrophobic (water-insoluble) part, such as a fatty acid or a rather long chain carbon group, such as fatty alcohols or alkylbenzene.

SOAPS Soaps are the sodium and potassium salts of the long chain carboxylic acid.A soap molecule consists of a long hydrocarbon chain (composed of carbons and hydrogens) with a carboxylic acid on one end which is ionic bonded to metal ion usually a sodium or potassium. The action of the detergent in maintaining the dirt in a highly dispersed condition is therefore important in preventing retention of detached dirt by the fabric. Wetting of the surface and, in the case of textiles, penetration of the fibre structure by wash liquor containing the. amphi = both) or amphipathic. The cleaning of such surfaces involves the displacement of this film by the detergent solution, which is in turn washed away by rinse waters. Soaps are denoted by the general formula RCOO-Na +, where R is any long chain alkyl group consisting 12 to 18 carbon atoms. The seemingly simple process of cleaning a soiled surface is, in fact, complex and consists of the following physical-chemical steps: If detached oil droplets and dirt particles did not become suspended in the detergent solution in a stable and highly dispersed condition, they would be inclined to flocculate, or coalesce into aggregates large enough to be redeposited on the cleansed surface.

The writings attributed to the 8th-century Arab savant Jābir ibn Hayyān (Geber) repeatedly mention soap as a cleansing agent.

A tension is created as the water molecules at the surface are pulled into the body of th… A soap has a large non-ionic hydrocarbon group and an ionic group COO-Na+. Four groups of surface-active agents are distinguished: The first detergent (or surface-active agent) was soap. Detergent Builders Builders give synthetic detergents the ability to dissolve in hard water, which contains charged molecules or ions that react with soap to lower its cleaning ability. Both are surfactants or, in other words, surface active agents. The chemistry behind a detergent is pretty basic and can be understood with little effort.
