Other chemicals, such as sulfur trioxide, sulfuric acid, and ethylene oxide, are used to produce the water-loving end of the surfactant molecule. The hydrocarbon plus the other chemicals creates the new, synthetic acid which is ready to be mixed with another agent.
Sometimes it is mixed with ethylene oxide to create a nonionic surfactant. Other times it is mixed with an alkali - usually sodium or potassium hydroxide - to make an anionic surfactant.
However, the differences in detergent ions is going beyond the scope of this post. I'd like to point out that the creation of detergents does not include glycerin which is why we use conditioner after shampoo and lotion after body wash. They not only remove oils which are our protective barrier, but also fail to moisturize via glycerin nor leave a moisturizing barrier behind. In labeling, detergents may not be called soap. It does not contain a full fatty acid only a hydrocarbon and it may or may not even use an alkali.
It's completely synthetic. It does not fit the definition of a soap; it's a detergent. However, this doesn't stop clever marketers from calling their product "beauty bar," "anti-aging moisturizing bar," or "deodorant bar. Often times people use the word "soap" when referring to anything that cleans -- for example, "dish soap," "hand soap," "anti-bacterial soap," etc.
Happy inside the micelle, the soil will not settle back onto the surface. Now that the soil is trapped in the micelle and the micelle is suspended in water, it is easy to wash the soil way. Remember the outside of our micelle loves water. So, as we rinse, the micelle floats away and we are left with a clean surface! Clothes Hands Dishes Surfaces. Learn More. About Ingredients. Ingredient Safety Initiative. Surfactants yellow cause water to lose surface tension, which is what keeps water separate from other materials Have you ever seen a bead of water sitting on a surface?
What is a surfactant? Like a magnet has two ends, one end of the surfactant is attracted to water molecules while the other is repelled. Every surfactant has two ends. One end wants to be in water and the other does not. How these two ends interact with soil and water is the secret to how a surfactant works. How Surfactants Clean Once the surfactant is added to water, the water-fearing ends try to stay away from the water.
