Why is detergent amphipathic?
Detergents are amphipathic molecules that contain polar or charged hydrophilic groups (heads) at the end of long lipophilic hydrocarbon groups (tails) (Figure 1). They are also known as surfactants because they decrease the surface tension of water.
Are all detergents amphiphilic?
3.1 Types of detergents. Detergents are amphipathic in nature, but structurally diverse. Detergents are classified based on either the hydrophilic head group or the hydrophobic tail group. Based on the head group, there are four categories of detergents—nonionic, anionic, cationic, and zwitterionic.

They have a charged polar head connected to two hydrophobic tails and form a bilayer (the hydrophobic tails are sandwiched between two faces of polar head groups). Found between these layers are your proteins and lipids.
Why is detergent neutral?
In addition to the cost savings, another reason for using a neutral detergent is the environmental benefit. Disinfectants are chemicals, so a detergent will nearly always be less toxic than a disinfectant.
What are the molecular properties of detergent?
Detergent molecular structures consist of a long hydrocarbon chain and a water soluble ionic group. Most detergents have a negative ionic group and are called anionic detergents. The majority are alky sulfates. Others are “surfactants” (from surface active agents) which are generally known as alkyl benzene sulfonates.
