hinoki oil replacer

Hinoki oil replacer is a fragrance ingredient with terpenic aromatic woody odour used mainly to impart woody notes in fragrance formulations.

General Material Description

Hinoki oil replacer, also known under the synonym chamaecyparis obtusa oil replacer, is a synthetic or semi-synthetic fragrance material formulated to mimic the characteristic scent of hinoki wood. It presents a terpenic and aromatic woody odor profile widely appreciated in perfumery and scented products. This replacer is designed as a substitute for natural hinoki essential oil, retaining key olfactory features while offering consistency and ease of formulation. The material is classified within fragrance agents and is recognized under names such as hinoki reco 19/75 (Charabot). Its sourcing involves chemical synthesis or modification processes to replicate the natural profile of Chamaecyparis obtusa extracts. For further chemical structure reference, see its PubChem record.

Occurrence, Applicability & Potential Uses

The hinoki oil replacer is primarily employed in fragrance compositions to impart woody odour qualities reminiscent of the natural hinoki tree, Chamaecyparis obtusa. This material does not commonly occur in nature but is a designed alternative to the natural essential oil extracted from the wood of the hinoki cypress. Its main application is in fragrance agents where a stable, consistent woody aromatic profile is desired. Regulatory standards such as the IFRA (International Fragrance Association) Code of Practice (Global) govern its safe use levels, particularly in perfumery and scent formulations. The replacer is not intended for flavour applications, aligning with IFRA recommendations limiting usage to perfumery.

Physico-Chemical Properties Summary

Hinoki oil replacer exhibits solubility characteristics typical of terpenic fragrance ingredients, being soluble in alcohol while insoluble in water. This solubility profile facilitates its incorporation into alcohol-based fragrance formulations but precludes applications requiring water solubility. The material's aromatic profile is dominated by terpenic and woody notes at full concentration, attributed to its chemical composition which supports volatility and scent diffusion. Its physicochemical traits influence formulation parameters such as miscibility, evaporation rate, and stability in finished products, assisting perfumers in achieving reliable woody sensorial effects.

FAQ

What is hinoki oil replacer and how does it relate to natural hinoki oil?
Hinoki oil replacer is a synthetic or modified fragrance material designed to emulate the woody aromatic profile of natural hinoki oil, which is extracted from the wood of Chamaecyparis obtusa. While natural hinoki oil is a complex essential oil obtained via steam distillation, the replacer offers a consistent, reproducible scent with terpenic and woody notes. It serves as an alternative ingredient in fragrance formulations, particularly when supply, stability, or regulatory factors limit the use of the natural extract.
How is hinoki oil replacer used in fragrance products, and what are its solubility properties?
Hinoki oil replacer is mainly incorporated into alcoholic fragrance bases owing to its good solubility in alcohol solvents. It provides woody odour characteristics that enhance perfumes, colognes, and other scented products. However, it is not soluble in water, which restricts its use in aqueous formulations without suitable solubilizing agents. The material is specifically intended for fragrance applications and is not used as a flavoring substance.
Are there any safety regulations or recommendations applicable to hinoki oil replacer?
According to the IFRA Code of Practice (Global), hinoki oil replacer is classified as a fragrance agent with specified usage limitations. Safety evaluations have found no classification for hazards under OSHA HCS (29 CFR 1910), and no specific precautionary statements are defined. Use levels recommended by IFRA exclude its application in flavoring contexts. Product formulators should consult current IFRA amendments and standards for compliance and ensure responsible incorporation in scent products.
