Pronunciation of rimel
Why is there no accent over the "i" in rimel?

The word rímel must be accented over the letter i. Check RAE dictionary for rímel. Here. But you'll find it written as rimmel (original trademark that originated the word) or rimel (whitout accent).
Given that the Spanish language depends on La Real Academia Española de la Lengua to establish wether whether a word is well written or not, there are many words that can be written (and actually they are) in different ways through its evolution: since the moment they start being used until the are finally included in the Spanish dictionary as neologisms.
The word clínex is another example. Coming from the trademark Kleenex, it has been being used in spoken language since these paper handkerchiefs first appeared (at least 20 years ago). And it hasn't been included in the RAE dictionary yet.
The most logical approach is to write these words trying to meet present spelling rules anticipating their standardization into the language. But this doesn't always happen and words like rimel (written without accent) remain in the limbo of the misspelled words without being aware of, because they were correct at the beginning.

Because the "i" is the penultinate syllable and is therefore emphasised anyway.
