Explanation:

A relative clause is a subordinate clause which specifies or gives information about a person or thing. In this case, the relative clause, that was on sale, gives further information regarding the noun soap. What is more, this relative clause is considered essential because it provides necessary information with respect to the noun it refers. If it was dropped, the sentence would not have the same meaning (see 1).

Sheila bought a particular soap, the soap which was on sale, not any soap. With the information included in the relative clause, the reader can identify which soap Sheila bought.
