egg yolk i think
as an emulsifying agent
yes

The three types of colloidal systems are sol, gel, and emulsion. In a sol, solid particles are dispersed in a liquid; in a gel, a network of solid particles is formed within a liquid; and in an emulsion, two immiscible liquids are dispersed in each other with the help of an emulsifying agent.

Yes, a surfactant can act as an emulsifying agent. Surfactants have the ability to lower the surface tension between two immiscible phases, allowing them to mix and form stable emulsions.
This mixture is an emulsion.
Methyl stearate is primarily used as a lubricant and emollient in cosmetics and personal care products. It is not commonly used as an emulsifying agent, as it lacks the hydrophilic properties needed to stabilize emulsions effectively. Alternative emulsifiers like polysorbates or lecithin are more commonly used for this purpose.
Water and oil form a colloidal dispesion.
egg yolk...?
In an emulsion, water is held by the emulsifying agent, which acts as a barrier between the water and the other components of the mixture. The emulsifying agent helps to stabilize the mixture by preventing the water droplets from coalescing and separating out. This allows water to be evenly dispersed throughout the emulsion.
Colloids are used in various daily life applications such as in food industry for stabilizing, thickening or emulsifying, in cosmetics for suspending particles, in medicine for drug delivery systems, and in the manufacturing of paints and pigments. Additionally, colloids are also used in wastewater treatment for removing impurities and in the production of nanoparticles for various advanced technologies.
