You run the risk of duplicate content. However, I can think of a way around it. Instead of just listing the ingredients exactly like the manufacturers do, instead, try to write it out. For example, you might say:
"This herbal conditioner contains ingredients such as blah, blah, blah and blah which are known for providing stronger, more durable hair..."
Basically, give the information, but put it in a unique sentence. That might help.
