Why Uranus and Neptune have a significantly different composition and higher density than Jupiter and Saturn?

Let's start with the( approximate) data. Here are the planets' densities
compared with water as the standard :
Jupiter 1.33
Saturn 0.69
Uranus 1.27
Neptune 1.64
You can see that Jupiter actually has a slightly higher density than Uranus.
So that makes the question a bit "wrong". Let's ignore that.
The composition of these planets is still not certain, but Neptune is thought to
contain water, methane and ammonia. All these are denser than hydrogen
which makes up a lot of Jupiter and Saturn.

What planet has the most helium in it?
By mass or volume, in our solar system Jupiter is the planet with the most helium, the fraction being about 10% of its composition (or a quarter of its mass). The smaller planet Saturn by comparison is believed to be about 3%. There are of course many extrasolar planets identified (orbiting stars other than our Sun), which are known to be gas giants and have much larger quantities of helium in them (including one which is about 17 times as large as Jupiter), but composition is hard to estimate with accuracy at such great distances.
