When it comes to describing something that is lacking fragrance, there are several synonyms that can be used. One such word is odorless, which simply means that there is no scent present at all. Another option is scentless, which is similar in meaning and suggests that there is no discernible aroma. Another option is unscented, which implies that the item is intended to have a fragrance but is lacking it for some reason (such as the absence of added perfumes). Yet another option is fragrance-free, which is often used to describe products such as lotions or shampoos that are designed for those with sensitive skin.
