Laundry detergents and household cleansers, for example, can also be formulated with surfactants. Although dish soap might seem like the perfect cleanser for all of your needs, Brashear says that you can't actually use it everywhere or on everything.
While it's great as a laundry pre-treater the ingredients that help cut grime on dishes also work to remove stains from clothing —especially greasy marks from food spills and other oils , it won't replace your laundry detergent. You should also never use dish soap in your dishwasher, combined with bleach, or on certain surfaces like cast iron cookware. Lauren Wellbank, Freelance Writer.

Try this experiment to find out. Washing up liquid is a kind of soap. Normally, oil and water don't mix, so they separate into two different layers. Soap breaks up the oil into smaller drops, which can mix with the water.
It works because soap is made up of molecules with two very different ends. One end of soap molecules love water - they are hydrophilic. The other end of soap molecues hate water - they are hydrophobic. Hydrophobic ends of soap molecule all attach to the oil. Hydrophilic ends stick out into the water. Otherwise, it is called a non-polar molecule. Whether molecules are polar or non-polar determines how well they mix. Nonpolar compounds , like oil and grease, cannot dissolve in water.
Polar compounds can dissolve in water. Most of what we call dirt is grease or oil which will not come off with just water. This is because oil and grease are non-polar, which means they will not dissolve in the water.
Soap can mix with both water and oil. The soap molecule has two different ends, one that is hydrophilic polar head that binds with water and the other that is hydrophobic non-polar hydrocarbon tail that binds with grease and oil. Since soap molecules have both properties of non-polar and polar molecules soap can act as an emulsifier. An emulsifier is simply an additive that helps two liquids mix. And if soap has been around for so long, why are we still talking about it today?
For these questions, we need lessons from public health and the social sciences. The benefits of handwashing with soap are numerous. It significantly reduces the risk of diarrhea, typhoid, respiratory illnesses, and lots of other waterborne and infectious diseases.
And because handwashing reduces illnesses and their long-term complications, handwashing also helps improve child growth, development, and school attendance around the world. The problem is that, despite the low cost and ease of using soap, handwashing with soap is rarely practiced as often as it needs to be. Handwashing with soap requires water and soap to be available when and where people are relieving themselves, and 2.
Education and behavior change interventions are needed, too. We can change this. Universal handwashing with soap is an essential part of the toolkit required to defeat diarrheal disease and help every child thrive. To reach this goal, governments, the private sector, civil society, and other stakeholders need to work together to promote handwashing with soap alongside clean water and sanitation.
We all need to give each other a hand — a clean hand, that is!
