Ammonium Lauryl Sulfate is another surfactant found in most cosmetic products.
Due to its very good cleaning and foaming properties, as well as a milder effect on the skin and hair (vs. SLS), Ammonium Lauryl Sulfate is often chosen for the production of shampoos, shower gels, shaving foams and many others.
The cleaning properties of Ammonium Lauryl Sulfate are directly related to its ability to produce large amounts of stable foam.
The ability to produce dense and stable foam allows to obtain fine and evenly distributed air bubbles.
Foam is a system where air (or other gas) is dispersed in a liquid.
Pure liquids do not have the ability to foam, but after adding surfactants, foam formation is observed in such systems.

Importantly, the good cleaning and foaming properties of Ammonium Lauryl Sulfate are preserved even in the presence of an excessive amount of sebum.
Ammonium Lauryl Sulfate belongs to the class of anionic surfactants.

ACTION IN SOLUTION of AMMONIUM LAURYL SULFATE:
Ammonium lauryl sulfate, like any other surfactant, makes a good base for cleansers because of the way it disrupts the hydrogen bonding in water.
Hydrogen bonding is the primary contributor to the high surface tension of water.
In solution, Ammonium Lauryl Sulfate anions and the ammonium cations separate.
The former align themselves into what is known as a micelle, in which the ions form a sphere, with the polar heads (the sulfate) on the surface of the sphere and the nonpolar hydrophobic tails pointing inwards towards the center.
The water molecules around the micelle arrange themselves around the polar heads, but this disrupts their hydrogen bonding with the water surrounding them.
The overall effect of having these micelles in an aqueous (water) environment is that the water becomes more able to penetrate things like cloth fibers or hair, and also becomes more readily available to solvate anything coming off the aforementioned substance.
FEATURES of AMMONIUM LAURYL SULFATE:
*Rich Lather:

BENEFITS / DESIRABLE PROPERTIES of AMMONIUM LAURYL SULFATE:
Good foaming capability (rich lather) — often a desired attribute in cleansing products.
Efficient at emulsifying / solubilizing oils and lipids in water, aiding removal of dirt, sebum, impurities.
Because Ammonium Lauryl Sulfate's ionic, generally compatible with many water-based cosmetic systems (assuming pH and ionic strength are managed).
Relatively cost-effective, and well-known / widely used in the formulation industry (so many formulator references).
MECHANISM IN SOLUTION / SURFACTANT BEHAVIOR of AMMONIUM LAURYL SULFATE:
Because Ammonium Lauryl Sulfate is amphiphilic (has a nonpolar hydrocarbon tail and a polar sulfate head), it acts as an anionic surfactant.
Above Ammonium Lauryl Sulfate's critical micelle concentration (CMC), the molecules self-assemble into micelles, reducing surface tension and enabling emulsification or solubilization of oily / nonpolar species in water.
ACTION of AMMONIUM LAURYL SULFATE IN SOLUTION:
Above the critical micelle concentration, the anions organize into a micelle, in which they form a sphere with the polar, hydrophilic heads of the sulfate portion on the outside (surface) of the sphere and the nonpolar, hydrophobic tails pointing inwards towards the center.
The water molecules around the micelle in turn arrange themselves around the polar heads, which disrupts their ability to hydrogen bond with other nearby water molecules.
Up to the critical micelle concentration, increasing amount of dissolved surfactant reduces the surface tension of the solution, which affords a greater ability to penetrate or "wet out" various surfaces, including porous structures like cloth, fibers, and hair.
Accordingly, this structured solution allows the solution to more readily dissolve soils, greases, etc. in and on such substrates.
Lauryl sulfates however exhibit poor soil suspending capacity.
