BETA-SANTALOL.

Valuable CAS 77-42-9 / PERFUMING

A primary sesquiterpene constituent of sandalwood oil, Beta-Santalol is a high-performance botanical isolate prized for its dual-action as a therapeutic skin-soothing agent and a luxury fragrance component. It bridges the gap between traditional aromatics and precision dermatology, offering potent anti-inflammatory and collagen-protective benefits.

Summary

Anti-inflammatory Antioxidant Skin Brightening MMP-1 Inhibitor Fragrance

Science

Mechanism of Action

Beta-Santalol functions as a phosphodiesterase (PDE) inhibitor and modulates the arachidonic acid pathway to decrease the production of inflammatory mediators like Prostaglandin E2 and Thromboxane B2. Beyond soothing, it acts as an anti-tyrosinase agent to brighten skin tone, scavenges reactive oxygen species (ROS), and inhibits MMP-1 enzymes to prevent the degradation of the dermal matrix caused by environmental pollutants.

Key findings

  1. 01 Demonstrated significant suppression of cytokines (IL-1b, IL-6, IL-8) at concentrations as low as 0.001%, showing anti-inflammatory potency comparable to ibuprofen (Sharma et al., 2014).
  2. 02 Proved effective at 0.1% in reducing atopic dermatitis symptoms when combined with colloidal oatmeal (Moy et al., 2012).
  3. 03 Higher concentrations (10-30%) in specialized ointments safely treated viral warts with minimal, reversible irritation (NCT01286441).

Because Beta-Santalol is effective at trace amounts (0.001%) for anti-inflammatory benefits, brands often list it at even lower levels solely for its aromatic masking properties without providing therapeutic value. For precision skincare, a concentration of 0.01% to 0.1% is required to claim biological efficacy.
