Unopened, well-formulated cosmetics can remain stable for a couple of years at room temperature, says Ni'Kita Wilson, a cosmetic chemist at Cosmetech Laboratories in Fairfield, NJ. But the clock starts once you bring a product home and open it.
How long does it take sperm to reach the egg? I would say at least a couple of hours, but it could take up to three days. Depending you your body and where the egg is in the cycle. The sperm that will be able to fertilize the egg will leave the cervix, at the most, 30 minutes. It does not take 3 days for the sperm to get to the fallopian tubes to ovulation.
Report Abuse. it can take up to 72 hours. what do u mean an egg will die after 24 hours? u ovulate for a few days honey-not just 24 hours. so as long as the sperm reaches the egg when you are ovulating u can get pregnant.ut, sperm can live for a few days in you, so they sit and wait for the egg. They can wait for up to 3 days. Once you ovulate however, the sperm go in search of the egg (again, only takes an hour or so). And contrary to what others said, the egg is only good for 6-24 hours. So, it's good the sperm work so fast! :).
