"...Some manufacturers add fragrance to their hand sanitizer formulation. Their logic is that the formulation is more appealing to caregivers and patients. However, a review of advantages and disadvantages listed in Kovach & Associates' annual survey of 120 directors of nursing across the United States would suggest otherwise....Fragrance becomes a problem due to the potential among caregivers and patients for allergic reactions to different fragrances. Directors of nursing cited fragrance as a factor in causing nausea in both patients and caregivers. A fragrance-free product is preferable. Similar survey comments regarding fragrance in the healthcare environment were seen in quotes associated with healthcare personnel hand washes, lotions and liquid body soaps..... so high fragrance levels can become a problem for caregivers and patients.
We have also heard some objections to the use of dyes in some formulations. These can leave stains or residue on caregiver and patient hands and clothes. It would be best to use a product that has no color additives or dyes in its formulation to avoid staining and possible skin irritation...."
