How do I break a loop of particles in the Character's Torso?

I'm trying to make a loop, but at the same time i want it to break after 10 seconds after the character spawns, so how do I do that?

Here's what I have so far:

while true do
	wait()
	script.Parent.CFrame = script.Parent.Parent.HumanoidRootPart.CFrame
	wait(10)
	if wait(10) then
		break
	end
end

script.Parent.ParticleEmitter.Transparency = 1

What I usually do to break loops after a set amount of time is by counting the number of times the loop has run. For example,

 edited code:

 n = 0 
 while true do 
 wait (0.04)
 n = n +0.04
 	    script.Parent.CFrame = script.Parent.Parent.HumanoidRootPart.CFrame
 --you want to continually do this for 10 seconds right?
 if n > 10 then -- after 10 seconds
      script.Parent.ParticleEmitter.Transparency = 1

      break
 end
 end

I am not sure how long wait() is but I think it is 0.04 seconds I will check. This should run for aproximentally ten seconds I think
