BETA-PINEN-3-OL.

Valuable CAS 5947-36-4 / PERFUMING

A bicyclic monoterpenoid alcohol, also known as trans-pinocarveol, frequently derived from botanical sources like Eucalyptus and Cistus ladanifer. This precision molecule serves as a dual-action restorative agent, bridging the gap between antimicrobial protection and accelerated cellular regeneration.

antioxidant antimicrobial skin-protecting fragrance regenerative agent

Science

It functions by neutralizing reactive oxygen species (ROS) and downregulating inflammatory cytokines such as IL-6 and TNF-alpha. On a cellular level, it stimulates the migration and proliferation of fibroblasts, which are essential for structural matrix repair and wound healing, while its molecular structure disrupts the cell membranes of Gram-positive bacteria.

Key findings

  1. 01 In vivo sensory and efficacy testing demonstrated significant antioxidant and antimicrobial activity at a 0.5% concentration in emulsion formats.
  2. 02 In vitro analysis of botanical hydrolates containing the molecule showed a 148.4% increase in fibroblast migration, indicating potent regenerative capacity.

Because it is often present as a minor constituent of essential oils, it is frequently used at 'dusting' levels for fragrance claims (below 0.01%) rather than at the 0.4%–0.5% concentrations required for clinical skin repair and antimicrobial benefits.

Stability

Highly compatible with nanoemulsion delivery systems; however, it is prone to acid-catalyzed degradation in environments with a pH below 3.0 and is sensitive to thermal degradation.

Synergies

  • Cistus ladanifer extract
  • Eucalyptus globulus oil
  • Tocopherol

Conflicts

  • Strong oxidizing agents
  • Low pH chemical exfoliants (AHA/BHA)
