It's a TFA flavor, advertised as a weak one, and not that popular for singleton use. From what I read, it will steep forward, so just wait a bit if it's freshly mixed. Even then, you may get more of a fruity candy effect than a specifically identifiable cotton candy. And...you may also wish you'd only used 8-10%
Most users say it's better used in a mix, as a sweetener. Very likely Ethyl Maltol is the primary ingredient.
