Zinc oxide complexes
US Patent 8404743
Publication date: March 26, 2013
Assignee: Mary Kay, Inc.
Described by this patent are compounds comprising a zinc oxide molecule chemically bound to one or more molecules having an acidic hydrogen, such as an organic acid. The compounds may be provided in topical skin formulations, pharmaceutical compositions or delivery systems for active ingredients. According to the inventors, this invention overcomes deficiencies in the art; while acidic molecules can be irritating to the skin, zinc oxide molecules can counteract this undesirable effect by providing a soothing quality to skin. Further, both the acidic molecule and the zinc oxide molecule can impart benefits to skin and produce a synergistic complex.
