TYRAMINE HCL.

Insufficient Data CAS 60-19-5 / ANTIOXIDANT, SKIN CONDITIONING - MISCELLANEOUS

Tyramine HCL is a trace monoamine known for its indirect catecholamine-releasing properties. While not extensively studied topically, a patent suggests its potential use in cosmetic formulations for skin lightening and reducing coloration caused by UV exposure.

Summary

Skin lightening Reducing UV-induced coloration

Science

Mechanism of Action

Tyramine HCL functions by inducing the release of catecholamines, such as norepinephrine, epinephrine, and dopamine, from pre-synaptic storage vesicles. It achieves this by entering noradrenergic nerve terminals and displacing norepinephrine, which can lead to vasoconstriction. Additionally, it acts as a monoaminergic activity enhancer for serotonin, norepinephrine, and dopamine, boosting their release. It is also a full agonist of the TAAR1 receptor. Although a patent proposes its application in skin lightening, the specific topical mechanism for this effect remains undefined in the available research.

Not reviewed
Sensitization risk Moderate

Tyramine hydrochloride carries GHS hazard statements, indicating it causes skin irritation (Category 2) and serious eye irritation (Category 2A), as well as respiratory irritation (Category 3). Under U.S. law, cosmetic ingredients do not require FDA approval prior to market entry, and there are no specific FDA approvals or restrictions for Tyramine HCL as a cosmetic ingredient noted in the research.

Our Assessment

Verdict

Insufficient Data

While a patent suggests potential for skin lightening and reducing UV coloration, the lack of independent clinical studies, unreviewed CIR status, and documented irritation risks necessitate further rigorous safety and efficacy data for a comprehensive assessment.
