I didn't find it at all like agave nectar. I really can't compare it to anything else. It is an emulsifier with other properties.
In US, you can't buy it in smaller quantities, at this time. Possibly, in England.
Curl Chemist mentioned that some Burt's Bees products contain it. I don't use "drugstore" products, so haven't really looked for it.
