How does oil & dirt get washed away with soap?

Written by Dr. George Grant

We use soap each day in our lives inrepparttar form of detergents, shampoo, shower crème, hand soap or bar soap. We are so used to using soap that we rarely stop and wonder how this wonderful compound manages to help us clean ourselves day after day. Have you ever thought about what would happen if there were no soap? How else can we ridrepparttar 149047 dirt off our bodies or our clothes?

Most ofrepparttar 149048 time, dirt comes inrepparttar 149049 form of grease or oil which sticks itself onto surfaces and will not come off if only water is just used. This is because oil and grease are non-polar, which means thatrepparttar 149050 oil molecules are not charged and therefore are not attracted to polar substances such as water. Because of this, oil tends to stick with its own molecules or other non-polar substances.

Onrepparttar 149051 other hand, water is a polar substance which is made up of one positive and one negative charge, and therefore is a fragmented substance. With this, water dissolves salt easily because salt is made up of charged ions in whichrepparttar 149052 positive charge will be attracted torepparttar 149053 negative ions in water.

Due torepparttar 149054 fact ofrepparttar 149055 nature of oil and water, you will see that oil will not dissolve in water but remain clustered onrepparttar 149056 surface. Also, oil and grease will stick onto plates and cutlery during cleaning, and no amount of water can completely remove it. That’s when soap comes in. All it takes is just one layer of soap with water andrepparttar 149057 oil will be removed. How does this happen?

Well, soap is a unique substance of potassium fatty acid salts, produced through a chemical reaction called saponification. Its molecules are made up of a hydrocarbon chain, which is non-polar, as well as a carboxylate molecule which is polar. Therefore,repparttar 149058 non-polar part ofrepparttar 149059 soap –repparttar 149060 hydrocarbon chain, is not attracted to water but to oil (lipophilic). Onrepparttar 149061 other hand,repparttar 149062 carboxylate molecules which are negatively charged, are attracted torepparttar 149063 positively charged water molecules (hydrophilic).
