How Shampoo Works and the Chemistry Behind It

You know shampoo cleans your hair, but do you know how it works? Here is a look at shampoo chemistry, including how shampoos work  and why its better to use shampoo than soap on your hair. What Shampoo Does Unless youve been rolling around in mud, you probably dont have hair that is truly dirty. However, it may feel greasy and look dull. Your skin produces sebum, a greasy substance, to coat and protect hair and the hair follicle. Sebum coats the cuticle or outer keratin coat of each hair strand, giving it a healthy shine. However, over time, sebum also makes your hair look dirty. An accumulation of it causes hair strands to stick together, making your locks look dull and greasy. Dust, pollen, and other particles are attracted to the sebum and stick to it. Sebum is hydrophobic. It waterproofs your skin and hair. You can rinse away salt and skin flakes, but oils and sebum are untouched by water, no matter how much you use. How Shampoo Works Shampoo contains detergent, much like you would find in dishwashing or laundry detergent or bath gel. Detergents work as surfactants. They lower the surface tension of water, making it less likely to stick to itself and more able to bind with oils and soiling particles. Part of a detergent molecule is hydrophobic. This hydrocarbon portion of the molecule binds to the sebum coating hair, as well as to any oily styling products. Detergent molecules also have a hydrophilic portion, so when you rinse your hair, the detergent is swept away by the water, carrying sebum away with it. Other Ingredients in Shampoo Conditioning Agents:  Detergents strip away the sebum from your hair, leaving the cuticle exposed and susceptible to damage. If you use soap or dishwashing detergent on your hair, it will get clean, but it may look limp, lacking body and shine. Shampoo contains ingredients that replace the protective coating on the hair. Silicones detangle hair, smooth the hair cuticle and add shine. Fatty alcohols help prevent static and fly-away or frizzy hair. Shampoo typically is more acidic than soap, so it may contain ingredients to bring down the product of the pH. If the pH of shampoo is too high, the sulfide bridges in keratin can break, weakening or damaging your hair.Protectants:  Many shampoos contain additional ingredients intended to protect hair. The most common additive is sunscreen. Other chemicals protect against heat damage from hair dryers or styling aids, chemical damage from swimming pools, or build-up from styling products.Cosmetic Ingredients:  Shampoos contain aesthetic ingredients that dont affect how well the shampoo cleans your hair but may make shampooing more pleasant or affect the color or fragrance of your hair. These additives include pearlised ingredients, which add sparkle to the product and may leave a faint glimmer on hair, perfume to scent the shampoo and hair, and colorants. Most colorants wash out with shampoo, although some subtly tint or brighten hair.Functional Ingredients:  Some ingredients are added to shampoo to keep it uniformly mixed, thicken it so that it is easier to apply, prevent the growth of bacteria and mold, and preserve it to extend its shelf life. A Word About Lather Although many shampoos contain agents to produce a lather, the bubbles dont aid the cleaning or conditioning power of the shampoo. Lathering soaps and shampoos were created because consumers enjoyed them, not because they improved the product. Similarly, getting hair squeaky clean actually isnt desirable. If your hair is clean enough to squeak, it has been stripped of its natural protective oils.

Shakespeares The Tempest Essay - 1735 Words

The Tempest raises many questions regarding the formation of authority and power. Is hierarchy understood as natural or as constructed? Also, what are the consequences when authority is usurped? This paper will attempt to answer these questions in a succinct manner using textual references to solidify its arguments. As the play progresses, Prospero constructs the hierarchy in such a way as to return things to their natural state. Any type of usurpation, whether attempted or successful, will always end up with power back in its rightful place, and most of the time with a lesson learned. The events that take place in the play are all made possible by the original usurpation against Prospero, the right Duke of Milan by Antonio, his†¦show more content†¦Antonios selfish refusal to recognize his particular place in the social and political hierarchy resulted in the overthrow of Prosperos dukedom and the consequent corruption of the natural harmony. Prospero expresses his di sdain for Antonio and his will to regain power when he says: I pray thee, mark me, -that a brother should Be so perfidious! Ââ€"he whom, next thyself, Of all the world I loved, and to him put The manage of my state; (5) So dry he was for sway, wi the King of Naples To give him annual tribute, do him homage, Subject his coronet to his crown, and bend The dukedom, yet unbowd, -alas poor Milan! Ââ€" To most ignoble stooping. (6) The first essential step that Prospero takes in order to regain his dukedom is to construct the storm (or tempest) itself. This storm, which rocks with force the very ship that Prosperos enemies are on, overturns the hierarchy on the ship. The storm at sea is instilled by Prosperos magic which permeates the actions of the characters until Act V when he removes his magicians robe. Not until then has its purpose of restoring his dukedom been accomplished. In a social and political society, the king would almost always exercise his authority over all of his subjects, but on this ship at sea he has stepped into the domain of the Ship-master and Boatswain and must now give in to their authority. These are the people who hold the kings life in their hands. The Boatswain sums it up nicely inShow MoreRelated Aime Cesaires A Tempest Clarifies Shakespeares The Tempest1683 Words   |  7 PagesCesaires A Tempest Clarifies Shakespeares The Tempest      Ã‚  Ã‚   Negritude, originally a literary and ideological movement of French-speaking black intellectuals, reflects an important and comprehensive reaction to the colonial situation of European colonization (Carlberg).   This movement, which influenced Africans as well as blacks around the world, specifically rejects the political, social, and moral domination of the West.  Ã‚   Leopold Senghor, Leon Damas, and Aime Cesaire are the three pioneersRead More Comparing Aime Cesaires A Tempest and Shakespeares The Tempest2940 Words   |  12 PagesComparing A Tempest and The Tempest  Ã‚     Ã‚  Ã‚   William Shakespeare wrote The Tempest, arguably his finest work, on the eve of European colonization of the New World in 1611 (Hollander and Kermode 445-46).
