What does Santalol do in a cosmetic formula?

This ingredient is used primarily as a fragrance material, giving woody, creamy, sandalwood-like notes in perfumes, skin care, hair care, and personal care products. It can also contribute mild skin-conditioning sensory effects because it is oil-soluble and substantive on skin.

Is Santalol clean?

From a clean-beauty perspective, this ingredient sits in the fragrance category, so the main issues are sensitization potential, disclosure, and IFRA-style use limits rather than broad formulation incompatibility. It is one of the fragrance allergens that may require label disclosure in some regions when present above threshold levels.

Is Santalol sustainable?

This material may be obtained from sandalwood-derived natural sources or produced through synthetic or biotech routes, and the sourcing route matters. Natural supply has a history of pressure on sandalwood trees, while managed plantations or fermentation-derived supply can improve traceability and reduce land-use strain.

Is Santalol COSMOS-approved?

It can fit COSMOS-natural or COSMOS-organic only when it is derived through permitted natural fragrance routes and used as part of a compliant fragrance system. Green Chemistry alignment is strongest with renewable, traceable sourcing and weaker for petrochemical routes or poorly documented natural supply chains.

How does Santalol work chemically?

The molecule is a lipophilic sesquiterpene alcohol, typically present as stereoisomeric forms with a C15 terpenoid skeleton and one alcohol functional group. It is used at fragrance-level concentrations, is not water-soluble, and benefits from protection against air and light because terpenoid fragrance materials can gradually oxidize during storage.
