Filter a column containing sentences with a column of words

Hi

I have a column of sentences in A, and a list of words in column B. I want the sentences in column A to appear in another target column (for example column C) if a they contain a word (not case sensitive) that is in the list of words in column B, and I do not want the same sentence to appear more than once in the target column.

Any ideas?

Thanks
