Why do companies put deer musk in their perfumes?

I brought free samples of perfumes (including the new ones of Sarah Jessica Parker and Jennifer Hudson) and started smelling them out. They all smelt differently, but had the same strong smell to it, which made it stink. I read the ingredients and they all had different ingredients, but the same main ingredient of deer musk. Why do perfume companies do that? I KNOW the perfumes will smell good if that deer musk wasn't in it. Why would they want people to not buy its product with that strong smell that stinks?Why do companies put deer musk in their perfumes?
The musk makes the perfume more powerful and it also adds endurance. Without it, you would probably have to reapply the same perfume dozens of times throughout the day to get the same effect as one with musk. HOWEVER..





I avoid supporting these sorts of perfumes for the point you made (smells weird) and also because buying products with musk even further threatens the population of the musk deer. Musk pods are only found in adult males, and many other deer are senselessly killed - on average, 160 deer are killed to yield only 1 kg of musk pods.Why do companies put deer musk in their perfumes?
So all of the young bucks chase after the doe......
