AMBREIN.

Insufficient Data CAS 473-03-0 / PERFUMING

Ambrein is a triterpenoid alcohol and the primary constituent of ambergris, serving as a precursor to aromatic compounds like ambroxan. It is traditionally valued in perfumery and luxury skincare for its potential conditioning and antioxidant properties.

Science

Biologically, ambrein functions as a non-selective antagonist, interfering with the mobilization of extracellular calcium ions. This mechanism may contribute to its observed soothing effects on smooth muscle and skin tissues.

Key findings

  1. 01 Studies indicate ambrein exhibits dose-dependent antagonism on smooth muscle contractions by interfering with extracellular Ca2+ mobilization.
  2. 02 In vivo animal studies suggest antinociceptive and aphrodisiac effects, though human clinical skin trials for efficacy are currently absent in public literature.

Our Assessment

Insufficient Data

Ambrein shows promising biological mechanisms and is widely used in luxury formulations, but lacks robust human clinical skin trial data to definitively establish efficacy for specific skin benefits.
