In chemistry, an amphiphile (from Greek αμφις (amphis) 'both' and φιλíα 'love, friendship'), or amphipath, is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving, nonpolar) properties. [1] Such a compound is called amphiphilic or amphipathic.
Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out with sodium chloride. Skeletal formula of stearin, a triglyceride that is converted by saponification with sodium hydroxide into glycerol and sodium stearate. Fat in a corpse converts into adipocere, often called "grave wax".
In a non-polar solvent, it is the exposure of the hydrophilic head groups to the surrounding solvent that is energetically unfavourable, giving rise to a water-in-oil system. In this case, the hydrophilic groups are sequestered in the micelle core and the hydrophobic groups extend away from the center.
The "cilantro soap gene" is a genetic factor that makes cilantro taste and smell like soap. A study from 23andMe reveals the OR6A2 gene as a possible cause for some people's distinct cilantro ...
The principal historical use of these plants was boiling down to make soap. Saponaria officinalis is most suited for this procedure, but other related species also work. The greatest concentration of saponin occurs during flowering, with the most saponin found in the woody stems and roots, but the leaves also contain some.
A handmade soap bar Two equivalent images of the chemical structure of sodium stearate, a typical ingredient found in bar soaps Emulsifying action of soap on oil. Soap is a salt of a fatty acid (sometimes other carboxylic acids) used for cleaning and lubricating products as well as other applications. [1]
Though smaller and larger sizes are available, from 15 g (0.53 oz) "guest soap" up to a 10 kg (22 lb) self-slicing block. [7] Marseille soap is frequently used for domestic cleaning, including hand-washing of delicate garments such as those made of wool or silk. In its liquid form it is commonly sold as a hand soap.
The advantage of using phosphates in a consumer laundry detergent or dishwashing detergent is that they make detergents more efficient by chelating calcium and magnesium ions. [1] The disadvantage of using phosphates is that they remain in wastewater and eventually make their way to a natural body of water. [1]
