Apart from alcohol, some hand sanitizers contain additives like fragrances, preservatives, and thickeners. Some of these additives, such as phthalates and parabens, have been scrutinized for their potential health risks. Phthalates, used to stabilize fragrances, have been linked to endocrine disruption, which might contribute to cancer risk. Parabens, used as preservatives, have also been associated with hormonal imbalances. However, these risks are generally considered low, especially with occasional use.
