Question 1

What does SANTALUM AUSTROCALEDONICUM WOOD OIL do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a fragrance component and masking agent, contributing a warm, resinous, woody scent profile to skin care, hair care, fragrance, and body products.

Question 2

Is SANTALUM AUSTROCALEDONICUM WOOD OIL clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally accepted when properly disclosed, but it carries the usual essential-oil caveats around fragrance allergens and skin sensitization in reactive users. It is more commonly flagged for allergen labeling and sourcing scrutiny than for broad restricted-list issues.

Question 3

Is SANTALUM AUSTROCALEDONICUM WOOD OIL sustainable?

Accepted Answer

This material is plant-derived from heartwood, so sustainability depends heavily on plantation management, harvest age, traceability, and documentation. It is expected to be biodegradable, but supply-chain pressure can be meaningful because the source trees are slow-growing and oil yield is limited.

Question 4

Is SANTALUM AUSTROCALEDONICUM WOOD OIL COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic standards when obtained by permitted physical extraction from an approved natural source and when the full fragrance-allergen disclosure requirements are met. Its Green Chemistry profile is mixed: renewable origin and low-solvent processing are positives, while slow biomass renewal and land-use pressure keep it from a stronger signal.

Question 5

How does SANTALUM AUSTROCALEDONICUM WOOD OIL work chemically?

Accepted Answer

The material is a volatile essential oil dominated by sesquiterpene alcohols, with smaller fractions of related sesquiterpene hydrocarbons that shape odor, volatility, and oxidation behavior. It is typically used at low fragrance levels, often below 1% in leave-on products, and should be protected from heat, air, and light because oxidation can increase sensitization potential.
