Something that does not cause irritation or discomfort.

Nonirritating → It is formed from "non-" (meaning not) and "irritating" (from Latin "irritare", meaning to provoke or annoy). The word "nonirritating" means not provoking or annoying.
Think of 'non-' meaning not, and 'irritating' meaning to provoke or annoy — so nonirritating describes something that does not provoke annoyance.
