RESEARCH OUTLINE:
You need to prepare a research outline. This should keep you focused and ensure all of the requirements are being met.
1. Introductory Paragraph: Define key words and phrases
What are surfactants? Surfactants are chemicals that reduce the surface tension between two liquids such as water and oil. It connects both polar and non-polar molecules. Surfactants contain both a water-loving head and oil-loving tail.
What do they do? – Surfactants lower the surface tension of a liquid. They change the properties of materials.
Examples: Sodium lauryl sulfate, ammonium laureth sulfate, disodium lauryl sulfuccinate
They can be in 3 different groups:
- Lipophilic (loves oil)
- Hydrophilic (loves water)
- Hydrophobic (repels …show more content…

There are anionic surfactants, they are negatively charged. There are cationic surfactants which are positively charged. There are amphoteric surfactants which are both negative and positive, and there are non-ionic surfactants which have no charge.

Anionic – detergent, remove dirt and oil, foam.
Amphoteric – used in cleansing products which include ingredients such as cocamidopropyl betaine, cocoamphopionate, and sodium lauraminopropionate. Less irritating and can make formula thicker which is idea for creams. Mild and gentle on the skin

Nonionic – good foam enhancers.
Cationic – positively charged. Cationic surfactants are mainly used for conditioning products as they are electrostatically attracted to the negative side, which allows them to be rinsed …show more content…

(change wording)
- Surfactants can break down oils and water
They are able to work with water and oil.

Cleansing – the most common use of surfactants in cosmetics is for cleansing. This is because skin and hair obtain a large amount of dirt from the environment, which is known as solid particulates, and from hair follicles known as oily deposits, which stays there. Lipophilic substances (oil loving) attract the oily deposits. Surfactants are used to get rid of them. Through the use of aligning lipophilic and hydrophilic ends, it is able to take the lipids off the exterior.

Foaming – Surfactant solutions can foam, as the air in liquids are trapped in the surfactant molecules. Foam is often desirable among consumers for cosmetics, so it is a key feature of surfactants.
Emulsification –A lot of cosmetic products want to add oily materials to it in order to have the preferred effect on skin and hair. These ingredients usually can’t be applied directly because they have undesirable aesthetic characteristics in their concentrated form. For this reason, cosmetic chemists create emulsions using
