if you have some time before it's due, i would write, email, or call a detergent company. offer to use their detergent and a competitor's. you could end up getting some free goodies for this

how about something that has to do with what the best powder for lifting prints is.\nthe hypothesis could be:\n______ powder is the best for lifting prints. does that make sense?  that way you could talk about all the advancements that have been made on the powders over the years.\nfor example lead powder vs. carbon powder.

When you softly place a pin onto the surface of water (horizontally) it doesn't sink because the weight of the pin is balanced by the upward (vertical) component of surface tension. When you add a detergent powder it reduces the viscosity of water and hence the upward force due to vertical component of surface tenbsion decreases and hence it sinks.

I've heard that liquid fabric softener works! It also works for stained coffee pots!

Washing normally removes impurities.  If you're using a separatory funnel to separate the aqueous layer from an organic layer, then you wash several times with water to make sure you have removed all ions, polar catalysts or reagents, etc.

Measure concentration. Use a dummy (with water only) measuring that with a LabPro probe. Then compare that to a certain volume of a variable soft drink. I did this in high school, hope it works!

I'm sure you mean, "What is the difference between a detergent and a soap?"\n\nA detergent is a general term that can mean any non-water solvent that one uses to clean. A soap is technically a specific kind of chemical compound that is usually the potassium or sodium salt of a fatty acid (can be an organic derivative, or can be synthesized). \n\nSoaps are kinds of detergents, but not all detergents are soaps.

I would advertise first.  Get the name out there.  Product recognition is key.  Then when your customer sees your product in the store, they will say to themselves, "oh, here is that detergent I've been hearing about. I think I'll try it".\n\nGood luck.

I would recommend looking into a study of a cleaning(cleanability vs surface finish) for processing equipment in the pharmaceutical industries. This has not been performed to my knowledge(I have thought about performing and writing a paper but haven't had the time), should be reasonably simple to to perform, and would open oppertunities into a growth industry.

(m)\n\nHot water does not freeze - cold water does.\n\nHot water cools faster than cold water because they both follow approximately the rate equation delta T = -k*dT/dt.\n\nAfter washing the stained clothes in both hot and cold water, we determined that cold water removed most of the stains more efficiently.  Cold water removed all of the stains that hot water did not, with the exception of grape juice and mustard.  Neither hot nor cold water removed oil or grass stains efficiently.  It different detergents and/or stain removal substances, such as Shout, were applied to the grass and oil stains, they would more than likely be able to be removed.  Since oil needs heat to dissolve, it would probably be effectively removed with the proper stain removers in hot water.  We decided that not just hot or cold water can specifically be used to remove all types of stains all the time.  Each stain must be treated accordingly using the right detergent and the right water temperature.  \n\n \n\nAlthough hot water is needed to remove some stains, it also tends to fade the color of materials.  If there are no stains in clothes, it is more efficient to use cold water because you are saving energy by not needing water to be heated.  If clothes need to be washed in warm or hot water, you can save energy but washing big loads of laundry at once and rinsing them on a different, cooler cycle.    \n\n\nCold water pressure washers are most suitable for car, deck, grill, patio, sidewalk, house, bus, and truck power cleaning. Also, if you have a car washing or an airplane washing business cold water power washers are the best fitting machines for it.\n\nOn the other hand, hot water pressure washers are excellent for oil, grease, and fuel spills, and for sanitization. Hot water pressure washers are also the best candidates for places such as garages, industrial plants, agriculture machineries, service areas, food processing plants, and airport environments.\n\nCold (40 - 50 degrees F) water is absorbed more quickly from the stomach. Also, if cold water is drank during physical exercise has the dual effect of also cooling the internal body temperature along with sweat produced by exercise. Since sweat is your body’s way of cooling itself, leave sweat on your skin and you should feel cooler.

They are chemical cousins but not identical  Baking soda is sodium acid carbonate, NaHCO3, while washing soda is sodium carbonate, Na2CO3.  Whether you can get away with the substitution depends on the nature of the project.

Seltzer water, vinegar, oxy clean...it depends on the stain. Usually any spray on stain remover made for children's clothing works the best. I use my daughter's for everything, they seem to be formulated the best for all around stains like food, dirt, etc.

this is new to me but you can try it out sock you cloth in water and add i can of cola into it let it soak and then put your detergent in it and wash as usual,got it from a good source my brother sent me the mail.

Any washing liquid will be a mixture of various substances, usually water-based.\n\nStandard components are detergents - molecules with a polar and an apolar end which can absorb on fatty (lipophile) substances and provide solution in the polar medium with their polar end. Classical soaps are sodium salts of fatty acids.\n\nOther ingredients vary strongly with the purpose of the washing up liquid. Perfumes, enzymes to digest specific types of pollutants, bleaching agents (usually oxydative), emulgators, Calcium-removers (like polyphosphate, zeoliths or chelating agents)...

Laundry detergents remove stains in a least 5 different ways :\n\n1. Most laundry detergents are alkaline. Being alkaline, they effectively act to saponify vegetable and animal fats and oils (turning the oils into a soap in the process) which are soluble/dispersable in water. So, things like sweat and sebum (skin oil) present in collar and cuff stains are partially solublised by the alkali.\n\n2. Laundry detergents contain a variety of different surfactants (sometimes called "tensides") that make the water "wetter" allowing the water to penetrate the stains, oils and soils present in dirt. The surfactant then bundles the dirt up in a little ball (called a miscelle) and floats it off the surface of the fabric.\n\n3. Many detergents contain a bleaching agent - usually either sodium percabonate or sodium perborate, which form hydrogen peroxide when dissolved, or sometimes a product like "chlorinated trisodium phosphate" which forms hypochlorite bleach when dissolved. These bleaches act on stains to decolourise them via oxidation.\n\n4. Most detergents contain a blend of enzymes which help to break down stains. Usually there is :\n\nA protease - which helps to break-down proteins (found in sweat, food stains, grass stains, etc).\n\nAn amylase - which helps to break-down sugars and starches\n\nA lipolase - which helps to break-down fats and oils.\n\nSome more modern powders also contain an enzyme known as "care-zyme", actually a cellulase, which helps to breakdown cellulose. Now, cotton is a cellulosic material so the addition of this enzyme works by breaking down part of the material it is cleaning. Luckilly, the enzyme is only capable of working on VERY fine bits of cellulose - no more than a few microns - so the result is that "carezyme" sort of dissolves the "fluffy bits" (known as "prilling") which you find on older clothes - the clothes wind up looking newer and cleaner!\n\n5. Most detergents contain  "optical brighteners" - compounds which absorb UV light and re-emit the light in the visible spectrum (usually at the blue end - to give a "blue-white" look which westerners regards as "clean" - but in some countries - Brazil, for example - they are tailored to give a "red-white" which is regarded as "clean" in those countries).\n\nThese five different and distinct parts of the powder act synergistically to give better cleaning than "soap and water".
