how long does it take for lotions and perfumes to go bad?

I think lotion will go bad within a year or 2. If you see it getting discolored or lumpy than throw it out.\n\nPerfume takes awhile to get old. Just make sure you keep it closed.

To make a perfume in a lab you first have to decide which molecule you want to make, either because u know it smells nice, or you want to know if it smells nice.  Then once you have a molecular structure, you devise a retro synthesis from the molecule you want back into starting materials that are small (less than 7 carbons is good) and cheap.\n\nYou then proceed work on the forward reaction from starting materials, a chemist would be able to synthesis a simple perfume from starting materials in 3-4 hours, assuming that there are no reactions that have very slow rates.\n\nOnce you have your molecule it has to go thru lots of tests to make sure it is safe for our skin ect, then it has to be made into a solution with a volatile compound for application, and possibly have more smelly molecules added into the mixture.\n\nI can't give u specific examples since perfume is the name for thousands of different molecules all made in different ways., just google it to find specific processes.  try the scent of Jasmin.

well if you dont have sensitive skin i would say no longer than 15 minutes tops! if you have very fair/ light skin that is sensitive I would say no longer than 8-10 minutes it can be painful if you burn! and be sure to use tanning lotions the can help prevent burning

with proper circualtion of air maybe like 5-10 hours and it depends on the size of the house. make sure u air it out u dont need to get high off the paint odors.

I worked in a lab and we got this question all the time.  We were always told it COULD be up to 30days. Now there are many factors to this, it depends how much exposer, some people release toxic chemicals faster than others etc.  For example, if you smoked pot one day then did it 14 days later, your earlier date some may still be in your system when then you just added a new fresh amount.  Even being around it, such as second had can enter the body. Here is the other glich, it all depends how much money the company wants to pay for the test.  If you are talking your normal lower cost employment test it is not as sensitive as others, now if someone (such as court cases) want to spend a lot of money they have test that can tell you what you have done in the last 3 years.

depending on your metabolism and percentage of body fat, drugs take anywhere from 3 days to 14 days to be eliminated from a person's body.  drink water and help flush it out.  eat a healthy diet and try taking some goldenseal.  good luck

depends on what kind\n\nyou apply it and it settles in the skin causing skin to be soft, moisturized and preventing dryness\n\nthere are several things inside lotions for different purposes really\nbut generally, they are to keep skin in good condition

You could have dry skin.  Maybe you are using a product that doesn't agree with you.

I know, it sounds like an oxy-moron (like jumbo shrimp). People buy Sour Cream-which is Cream gone bad--and they put an experation date on it? Go figure..\nThe one I couldn't figure out is the bottle of Aquafina with an expiration date...water gone bad?

What do you mean by "it has expired?"\n\nYou have the paper script that has an expiration date? That's unusual, most written scripts are good for 6 months (depending on what it's for). If that's the case, call your doctor or pharmacist and ask them if they can fill it anyway or call in a replacement.\n\nYou have a bottle of pills that has an expiration date? If that's the case, no problem. Most pills have a significant shelf life before any sort of deterioration starts to occur. You'll notice when you fill a script it always says to discard 1 year after it was filled. Some prescriptions are sensitive to light and heat, but most are pretty stable. You don't know how long that pill was in a factory, a warehouse, a distribution center, a re-seller, and then in your pharmacy before getting that sticker saying "good for 1 year."\n\nIf it's in the bottle, you're probably okay. If you're worried, call your pharmacist and ask if they can replace what you haven't taken. - I doubt they will, but it's worth a shot.\n\nOdd

It's not so much that is goes bad as in "rotten."  The plant essences/extracts that it is made from get rancid.  It's going to go bad faster if it's exposed to high temperatures and if you chose to keep it in the fridge you could make it last longer...but applying icy perfume doesn't sound like much fun to me.

some times only a day but if its bad and then you end up sweating cause its hot out or something it can last 3 or 4 days.

liquids develop bacteria so a year is considered the safe limit.\nWith dry pills and powders that were stored out of sunlight, they are safe and effective for 10 years or more!
