Lipids in detergents or soap act as surfactants, which help to reduce the surface tension of water and break down oils and grease. This allows for better cleaning by lifting dirt and grime off surfaces and enabling them to be rinsed away.

Soap is made from natural ingredients like fats and oils, while detergents are synthetic compounds. Soap is biodegradable and can be less harsh on the environment, while detergents are designed to be more effective at removing dirt and stains. Additionally, detergents are more suitable for hard water compared to soap.
Matter can be insoluble in alcohol in soap and detergents because alcohol is hydrophilic (water-loving), while some components in soap and detergents are hydrophobic (water-repelling). This difference in polarity between the alcohol and the matter prevents them from mixing and dissolving in each other.
Lipids dissolve in soap because soap molecules have both polar and nonpolar components. The nonpolar tail of the soap molecule can interact with the nonpolar parts of the lipid molecules, while the polar head of the soap molecule can interact with water, allowing the lipids to be surrounded and solubilized in water.
Most laundry powders contain detergents as their main cleaning agents. However, there are some natural alternatives available, such as soap nuts or soap berries, which do not contain synthetic detergents. These natural alternatives can be a more eco-friendly option for washing clothes.
Detergents are synthetic surfactants that are effective in hard water, while soaps are made from natural fats and oils and may leave a residue in hard water. Detergents are also more versatile and can be used in a wider range of water temperatures.
