These surfactants keep the …The Chemistry of Cleaning | The American Cleaning ...This is important here! The water-fearing end of the surfactant is made up of hydrocarbon chains. A hydrocarbon is a molecule that is made of hydrogen and carbon. The chains love oil and grease and will try to stay away from water. The water-loving end is known as the hydrophilic end. We learned hydro- is a Greek root meaning ‘water’.

Detergents are amphipathic molecules called surfactants. The more polar the hydrophilic portion of the molecule, the more effectively it works as a detergent. The structures of two common detergents, sodium dodecyl sulfate (SDS) and sodium stearate (soap), are shown below in the A- forms. The pKa value for each substance is listed. SDS (pK a = 1.7)

M. Miyake, Y. Yamashita, in Cosmetic Science and Technology, 2017 Abstract. Surfactants spontaneously construct a variety of self-organized structures in solvents, which noticeably depend on the chemical structures of surfactants as well as interaction manners with the solvents. A phase diagram is a key tool to give an interpretation to surfactant properties and, …

2010 Surfactants and Detergents - AOCS

Extended surfactants contain an intermediate-polarity spacer, such as polypropylene oxide, between the head and the tail of a surfactant molecule. Owing to their unique properties, extended-surfactants show ultralow interfacial tension with highly hydrophobic oils, such as vegetable oils and hexadecane. In this work, we study the effect of ...

Surfactants | Use, Benefits, and Chemical Safety Facts

Surfactants are compounds used in an array of cleaning products for their ability to lower the surface tension of water, in essence making the molecules slipperier, so they are less likely to stick to themselves and more likely to interact with oil and grease. Beyond soaps and detergents, surfactants are used in lubricants, inks, anti-fogging ...

Ingredients -- Detergents and Surfactants

Detergents and soaps are surfactants, short for surface-active agent . Surfactants have a hydrophilic side of the molecule attaches to water, and a hydrophobic side of the molecule that avoids water. In the absence of oils, the hydrophobic side sticks out of the surface of the water drop. There is no longer any water at the surface to form a ...

As surfactants are amphiphilic structures with a non-polar hydrocarbon tail and polar (usually ionic) head group, they arrange themselves into micelles in polar solvents, such as water. This is due to the hydrophobic effect, in which surfactants arrange themselves into a …

Surfactants in Detergents - How Do Surfactants Work

Dec 27, 2020·Surfactants in Detergents. Surfactants in detergents play a vital role of breaking down and removing dirt from surfaces such as clothes, skin, or surfaces. Surfactants are highly effective in this capacity as they are able to disturb and break down the interface that exists between oils, water, dirt, and other contaminants.

Surfactants - Essential Chemical Industry

Surfactants. Surfactants are one of many different compounds that make up a detergent. They are added to remove dirt from skin, clothes and household articles particularly in kitchens and bathrooms. They are also used extensively in industry. The term surfactant comes from the words surface active agent. Figure 1 Surfactants aid the effective ...

What are surfactants and how do they work? - Biolin Scientific

The term surfactant comes from the word surface active agent. They are amphiphilic molecules and are thus absorbed in the air-water interface. At the interface, they align themselves so that the hydrophobic part is in the air and the hydrophilic part is in water. This will cause a decrease in surface or interfacial tensions. Surfactant basics ...

Surfactant - an overview | ScienceDirect Topics

Surfactants reduce the surface tension of cleaning solutions, thereby providing the solution with better wetting properties. Each surfactant combines in its molecule a hydrophilic and a hydrophobic group. Therefore, surfactants are vertically adsorbed at the water interface, causing a compressive force to act on the surface.
