...Why People Dye Their Hair Many people of different ages ask of teens the question, "Why do you dye your hair?" It's a valid question. It seems like the fad these days is to have a different color of hair every week. Red, purple, blue, green, orange, it doesn't matter, as long as it's new. The crazier the better, the brighter the cooler. I feel I'm experienced in this area, as I've dyed my hair at least a dozen times in the last couple years. Why do we do it? Most hair dyers probably aren't entirely sure of their ulterior motives behind the florescent colors, but I decided to figure it out. When someone dyes their hair a noticeably bright color, they get noticed. It's impossible not to see the green haired girl walking down the hall, or the blue haired boy in your gym class. It's immediately the way you're first described by your peers. This attracts attention to you, and makes you more known around your school. Everyone's talking about your new hair color, about how "crazy" and "cool" it is; or maybe how "gross" it is, depending on how it turned out. You could look like a way cool punk rocker, really trendy, or like your hair grew some major mold. It can depend on the dye or the way you dye it, or sometimes on pure luck. Sometimes people dye their hair because they need a change. They're sick of the brown-haired, boring old person they see in the mirror every day, and want to add a little spice to their look. It's really hard to be boring looking when your hair can be seen from...

...Title: Isolation and Process Optimization of textile dye degrading bacteria Abstract: Bacteria can remove dyes from wastewater and soil, leading to a decrease in their toxicity. The detoxification rate depends upon media and culture conditions. The decolourization/removal of textile dyes like bromophenol blue, methylene blue, methyl green, and malachite green, in addition to various other industrial dyes, using bacteria isolated from soil has been an important area of research for bioremediation and the present work is focused on this specific aspect. The effect of independent variables such as time, temperature, pH, and agitation on decolorization efficiency of bacteria has been optimized. Biodegradation of methylene blue and bromophenol blue was demonstrated by monitoring the effects of the different parameters and determining optimal conditions for degradation activity. Introduction Several industrial activities, such as textile dyeing, olive oil extraction and the manufacture of pulp and paper are characterized by intensive water consumption rates. They release huge amounts of more or less coloured effluents into the environment. As far as synthetic dye release is concerned, textile dyeing facilities and the manufacture of dyestuffs are two major polluting sources. In addition, traditional textile dyeing processes generate a large amount of coloured effluents, because about 100 litres of water are required to process 1 kg of dyed fabrics. Moreover, up to 15% of applied...

...INTRODUCTION Background of the Study Dyes are commonly used in our industry. Many dyes are too expensive and that is why many people find ways to have a cheaper one. Syzygium Aqueum or locally known as Tambis is a common tree in the Philippines and some part of Asia. The seeds of this tree have been found out by the researcher that it has biological active compounds of tannins which are needed in producing dyes. In this study, the researcher concluded that the leaves extract also of the said tree may possibly contain also a biological active compound of tannin which will be use as the raw material in producing dyes. Thus, this will be a great help to people in many ways such as drawing activities, colouring activities, and etc. Statement of the Problem This study aims to answer these following questions; 1. Is there any significant difference between the color of the extract of Tambis leaves from Turmeric Rhizome dye? 2. Is there any significant difference between the effectiveness of Tambis leaves extract from Turmeric Rhizome dye? 3. Is there any significant difference between its long lasting effects of Tambis leaves from Turmeric Rhizome dye?

Besides, the a and b which represents the distance travelled by pigment and distance travelled by solvent were measured and recorded in the table. The Rf value was then calculated by using the formula ab. A= distance moved by the pigment from its original position B= distance moved by solvent from the same position. *Round Rf values to 2 decimal places CONCLUSION: We used paper chromatography to separate the pigments found in spinach. Since plants use several different pigments to capture light energy for the light dependent reaction in photosynthesis, we expected that we would see several different bands of pigments on our chromatography paper. As the data in Table 1 indicates, we obtained four bands of different pigments from the spinach leaf: yellow- brown, light green, green, and yellow. The bands moved different distances up the chromatography paper, and were of different widths. According to the data, our hypothesis was correct. Different types of pigments are present in plants. The distances traveled by the pigments can indicate how big...

...AMERICAN JOURNAL OF UNDERGRADUATE RESEARCH VOL. 8, NO. 1 (2009) Cyanine Dyes: Fine Structures in Their Absorption Spectra Anna Zarow and Yeung-gyo Shin Department of Chemistry/Physics Kean University 1000 Morris Avenue Union, New Jersey 07083 USA Received: October 13, 2008 Accepted: May 19, 2009 ABSTRACT Absorption spectra were studied for two series of 3 cyanine dyes with varying length of conjugated hydrocarbon chains. Fine sturctures in absortpiton spectra were analyzed to –8 determine its concentraion dependence as the concentraion of dyes were changed from 10 M to –4 10 M. In all 6 dyes studied, ratios of minor peaks to the major peak remained constant within the experiemntal error. These results indicate that the origin of the absorption fine structure is due to the electronic coupling, an intramolecular process, rather than the aggragates formation, an intermolecular process. I. INTRODUCTION cm‾ . This observation is not accordance with Particle in a Box estimation nor a state of the art computational method [7-9] which predict the absorption spectra of these dyes to be consist of a smooth single peak. One possible explanation of the caused for the splitting is attributed to the ability of the dye molecules to form dimmers or trimers as mentioned in “Experiments in Physical Chemistry”. This explanation is very attractive one since resonance structure prevalent throughout the molecule implies extensive -electron network that forces the molecule to be planar. More...

...Food dyes are used in many common foods. There are some food dyes that are banned, some that people are allergic too, and some that ADHD kids cannot have because there is suspicion that it may cause hyperactivity. I wanted to research this to see what grape drinks people can have that has the least amount of dye in it. Some food dyes, or food colorings, are banned from the United States and other countries. These food dyes consist of FD&C Orange No. 1; FD&C Red No.32; FD&C Yellows No. 1, 2, 3 and 4; FD&C Violet No. 1; and FD&C Reds No. 1 and 4. The Food and Drug Administration (FDA) is an agency of the United States federal government that tests, inspects, approves, and sets safety standards for foods, food additives, drugs, cosmetics, and household medical devices. Many countries with the same food coloring controls, like Canada and Great Britain, also banned the use of Red No. 10 and Yellow No. 5 is also always undergoing test. In the 1970s, a soviet scientist claimed a link between the dye and cancer. The U.S. test proved some correlation as well. It was never linked to death or illness, but the substance was banned from the United States in 1967. Some people are allergic to food dyes. A dye called cochineal dye, also called carmine, is not harmful to most people, but there have still been reports of patients having...

...How people in ancient times created color for their garments. Greek philosophers Democritus and Aristotle and Roman writers Plinythe Elder and Vitruvius described and recorded processes to create fabric dyes. Blues and purples were known as vat dyes. Indingo and woad (a European flowering herb of the mustard family) were used to make blue dyes. These plants required lengthy absorption in an alkaline solution of ash, lime, or urine, which turned them into a water-soluble salt. The fabric was left to air dry and the oxidation made the blue color fast. Tyrian, or royal, purple came from the mucous gland of the murex, a mollusk (invertebrate). A pound of dye required four million mollusks which was a time consuming process. Only the rich, such as the reigning emperor or monarch could afford this shade. Reds were mordant dyes (sarcastic/biting dyes). They required the use of a fixative to create an insoluble color that would remain true. Henna a shrub and madder, a root, were mixed with alum (a sulphate of aluminum and potassium) to render a color family way less intense than the red we know today. A species of female scale insect, kermes was used by the Egyptians and produced a more vivid/intense red. Colors in the yellow family were the least complicated. They were direct dyes, produced with little effort. Weld, the seeds, stems, and leaves of Dyer’s Rocket; and safflower, petals from Dyer’s Thistle, were used to create...
