Because acid is very harmful to the cotton and acid spoil the cotton and convert it to Hydration cellulose also the acid cause separation of chains of cellulose in the cotton. If we want to emaciate the cotton we use H2So4.and acid dyes usually need acid PH from 2 to 3. And as i said before it emaciate the cotton.

Cotton candy is almost pure sugar. Sugar is essentially neutral, as it does not ionize in water.

If you must choose between saying cotton candy is an acid or a base, choose weak acid. Sugar can be a food source for bacteria or other organisms; these usually produce an acid (though sometimes its a base) as a waste by-product
