Science
Mechanism of Action
Santalum Album Wood Powder is rich in bioactive compounds such as santalols, sesquiterpenes, and phenolic acids. These constituents impart significant anti-inflammatory actions, effectively diminishing redness, swelling, and irritation. Functioning as a potent antioxidant, it neutralizes free radicals and shields the skin from damage induced by environmental aggressors like urban dust and blue light. Its broad-spectrum antimicrobial activity targets bacteria, fungi, and other pathogens, thereby preventing infections and reducing acne-causing microbes through biofilm inhibition. Furthermore, it offers calming effects and may promote wound healing by stimulating collagen synthesis and angiogenesis. Alpha-santalol, a key component, may also contribute to inhibiting abnormal pigmentation by moderating tyrosinase activity.

Dusting Analysis
As a fine, ground powder, Santalum Album Wood Powder is typically incorporated as a dispersible particulate in dry formulations, masks, or scrubs. While not a solubility issue, its particulate nature requires careful formulation for uniform dispersion and application to ensure optimal product performance.
The Formula
Formulation
Stability
Santalum Album Wood Powder itself is primarily a dispersible particulate. However, its beneficial components can be extracted; sandalwood extract powder is noted as soluble in water and alcohol, while sandalwood oil (derived from the wood) is soluble in oil. Formulators should consider the specific form (powder, extract, or oil) for solubility and ensure proper dilution if utilizing oil derivatives. Sustainable sourcing and purity, free from fillers or synthetic fragrances, are critical considerations.
Safety
Safety Profile
Sandalwood oil (derived from Santalum album L.) and its primary constituent, alpha-santalol (>90%), are approved by the FDA, FEMA, and CoE for food use, considered safe at current levels. It exhibits low acute oral and dermal toxicity and is non-mutagenic. When properly formulated and diluted, sandalwood oil is generally considered safe for cosmetic use, non-comedogenic, and non-phototoxic. However, isolated instances of irritation or sensitization reactions have been reported, indicating a small segment of the population may be allergic. Indian sandalwood oil may offer a milder profile for sensitive skin due to the absence of farnesol, a known irritant in Australian sandalwood. Patch testing is advised prior to full application.
