What is the mechanism of cleaning action of soap?
When soap molecules are present in water, the molecules arrange themselves in the form of a cluster in such a manner that their hydrophobic ends are away from the water molecules and their hydrophilic or ionic ends are towards the water molecules. This is known as micelle formations.Cleaning action of soaps:The dirt (oil and grease) present on clothes is organic in nature, and insoluble in water. Hence, it cannot be removed only by washing with water. When soap is dissolved in water, its hydrophobic ends attach themselves to the dirt and remove it from the clothes.Then, the molecules of soap arrange themselves in micelle formation and trap the dirt at the centre of the cluster. These micelles remain suspended in water like particles in a colloidal solution. The various micelles present in water do not come together to form a precipitate as each micelle repels the others because of ion-ion repulsion. Thus, the dust particles remain trapped in the micelles (which remain suspended), and are easily rinsed away by water. Hence, soap micelles remove the dirt by dissolving it in water.
Does bleach dissolve some plastics? If so, which ones? (And why?)
I presume you’re talking about common household bleach (like Clorox brand) which is a sodium hypochlorite solution, as opposed to household oxygen bleaches (sometimes dubiously referred to as “color safe” bleaches) or the many commercial bleaches used in industrial processes.I can’t give you a definitive answer for every plastic, but most plastics can be safely treated with a diluted solution of household bleach (no more than a tablespoon of bleach to a cup of water) without ill effect. Don’t let it sit too long and rinse it thoroughly with water. Clorox even recommends using a dilute bleach solution for cleaning plastic baby toys and plastic kitchen containers. Note that most bleach bottles you find at the store are themselves made of plastic, specifically polyethylene, and can hold even concentrated bleach solutions for extended periods of time.Now for the fine print: bleach—especially undiluted-- can attack some of the plasticizers used to give certain plastics desired properties (like flexibility) which can change the properties of these plastic in undesired ways. And I would not be surprised to find that there are plastics out there (particularly ones related to natural rubbers, such as latex or neoprene) that can be affected by household bleach.
Lysol and scrubbing bubbles?
thanks guys.. and i didnt intentionally mix the two together it was more like i was using the scrubbing bubbles and then when i went to use the lysol toilet cleaner i dropped it where the scrubbing bubbles were setting in.. but i researched and found out they were mainly the same ingredient so its okay .. but i appreciate it =)
I got a burn on my chest from a space heater &it burnd a imprint of the wire on my skin, it hurts HELP?
cold water is the best/only first aid when you burn yourself - 20 minutes under the tap and no less. NEVER ice OR vinegar OR milk OR butter OR green tea OR mustard OR toothpaste OR sunscreen OR semen OR vaseline OR tomatoes OR vanilla extract OR yogurt OR sour cream OR egg white OR egg yellow OR lavender oil OR cocoa butter OR salt OR tea bags OR potato OR shaving cream OR olive oil OR baking soda OR banana peel OR petroleum jelly OR whipped cream OR avocado OR bacon grease OR corn starch OR turmeric OR lemon juice OR curd OR pickle juice OR saffron OR honey OR soy sauce OR urine OR talcum powder OR mashed strawberries OR exfoliating scrub OR mayonnaise OR peroxide OR bleach OR deep heat OR ketchup OR red grapes OR hairspray OR WD-40 OR flour OR pancake syrup- not until the skin is fully healed! I would advise that you cover the burnt area with white soft paraffin (white petroleum) or aqueous cream bp. (check the links below and see if you can find a local equivalent). wash the burn and reapply every 4-6 hours - cover with cling wrap if you wish to cover with clothes - this will stop your clothes getting covered with paraffin and maintains the burn. cling wrap alone is also ok if you can't get hold of any paraffin. it acts as a protective artificial skin - helping retain moisture and protect from further damage and pain. aloe is good coz it remoisturises but that moisture can be quickly lost as the skin can't contain fluids. so put aloe on, and then the paraffin on over the top. if there is broken skin leave out the aloe - just paraffin. http://www.doorone.com.au/xGS-Aqueous_Cream~NS-1~linkin_id-8009837 http://www.pharmacyonline.com.au/david-craig-paraffin-400g-p-1831.html http://www.cvs.com/CVSApp/cvs/gateway/detail?prodid=134100&previousURI=/CVSApp/cvs/gateway/search?page=1^Query=White+Petrolatum^ActiveCat=65 email if you still have questions - send photos feedingthedogcustard@hotmail.com finally if you are really worried go to a hospital that has a burns unit or plastic surgeons. serious sunburn i.e. blisters (and all other burns) should be seen by a burns trained doctor or nurse.
Can you remove your fingerprints from an object?
Human fingerprints on surfaces are primarily composed of oily residue due to the natural oils in human skin being deposited on the surface, how well they form in the first place as well as how easily they can be removed is significantly affected by the nature of the surface.Non porous surfaces like glass, metal, plastic, wood varnish and similar the fingerprints can generally be removed by simply wiping the surface clean, use of a damp cloth or a cleaning solution which is designed to break down oily residues can help to remove stubborn fingerprints. Examples would be window cleaning products, dishwashing soap etc.Porous surfaces like paper can retain fingerprints more easily since they can absorb some portion of the oil leaving a mark not dissimilar to a watermark in the fibres of the paper and can be revealed when the paper is held up against a light source. Removing all traces of such prints without damaging the fragile paper itself is very difficult.
