بسم الله الرحمن الرحيم
(Fatwa: 172/116/SD=2/1439)
If there is no surety or presumption that some haram or impure thing is mixed in cold drinks then its business is not unlawful and haram. But if someone avoids such business on his own wish then there is no problem in it, rather it is better.
Allah knows Best!
