The FDA explains that the term hypoallergenic has no specific federal definition in the United States. This entry provides that context to help readers understand a marketing claim without interpreting it as a guarantee that reactions will not occur. Its scope is limited to the U.S. source and does not describe all jurisdictions. To assess a specific product, it is useful to consult its documentation and ingredient list.
Olfactory descriptions are not equivalent to an ingredient list. The properties of an ingredient do not automatically transfer to the finished product.
