No they do not. Hahahahaha Science Diet does not make a truly hypo-allergenic food. (Please see dogfoodanalysis.com to see the ratings on all Science Diet food). Their foods all have corn, wheat, soy, by products, etc in them none of which are hypo allergenic, in fact corn and wheat are two of the most common allergy ingredients.
If you want hypoallergenic I'd go with a grain free diet and/or a limited ingredient diet. Natural Balance makes a limited ingredient frain free line which has been GREAT for us, Wellness also makes a limited ingredient diet (although it's not grain free), Wellness also makes a grain free diet (although it's not limited ingredient).
Do you suspect your pup has allergies? Why are you considering a hypo-allergenic diet versus just a good healthy food?
