Irritation, in biology and physiology, is a state of inflammation or painful reaction to allergy or cell-lining damage. A stimulus or agent which induces the state of irritation is an irritant. Irritants are typically thought of as chemical agents (for example phenol and capsaicin) but mechanical, thermal (heat) and radiative stimuli (for example ultraviolet light or ionising radiations) can also cause irritation.

Everyone is giving nice opinions, but it looks like once again no one bothered to look it up, so the answers so far are full of mistakes.
"Irritation" has nothing to do with cells or cell lining but is a SUBJECTIVE SENSATION of discomfort.
"Inflammation" is an OBJECTIVELY DETERMINED condition defined by five cardinal signs: calor, rubor, tumor, dolor, and function laesa, or warmth, redness, swelling, pain, and impaired function.
The causes of each are myriad, but the essential difference between the two is the subjective vs. objective determination.

Well inflammatioin is when something is swollen.
But irritation is like when you poke your eye.
They're really not related much.
