Theaspirane CAS 36431-72-8 | Tea & Woody Aroma Chemical
Theaspirane Product Overview
Theaspirane (CAS 36431-72-8), also known as Theaspiran or Spiroxide, is a liquid aroma chemical used for distinctive tea-leaf, green herbal and woody notes. Its cooling, faintly camphoraceous and fruity nuances support fragrance and flavor compositions, including fine fragrances, personal care fragrances and selected flavor applications.
Commercial Theaspirane is commonly described as a mixture of stereoisomers. Aroma character and the specified total-isomer content are important for matching a supplied grade to an established formulation.

Odor Profile & Fragrance Character
Theaspirane combines a leafy tea impression with green herbal and woody depth. Supporting facets may be minty or camphoraceous, with delicate fruit-like tones. The exact odor balance depends on the grade, isomer profile and concentration in the complete accord.
It is useful where a perfume or flavor composition calls for green complexity rather than a simple sweet tea note. It may complement berry, floral, aromatic-herbal and woody materials in a balanced formula.
Applications of Theaspirane
Tea & Herbal Fine Fragrance
Adds leaf-like tea character, dry greenery and woody depth to green tea, black tea and aromatic-herbal perfume directions. Its cool facet can offset excessive sweetness in floral or woody blends.
Berry, Fruit & Floral Accords
Contributes a green and slightly woody contrast in berry-inspired and soft-fruit compositions. It can also bring a subtle tea-leaf facet to floral accords when blended with compatible aromatic materials.
Woody & Tobacco-Leaf Perfumes
Supports perfumery concepts built around dry woods, aromatic foliage and tobacco-leaf impressions. The green-camphoraceous nuance links fresh top-note materials with deeper woody accords.
Personal Care Fragrances
Relevant to professionally developed scent concentrates for shampoo, body wash, soap and lotion. It supplies an aroma note, not a skin-care active; finished-formula compatibility and use levels depend on the application.
Home Care & Air Care
Can be used in fragrance blends for green-leaf, herbal, tea or woody household scent concepts. Suitability depends on the product base, fragrance system and final end-use requirements.
Tea, Herbal & Fruit Flavors
A documented flavoring substance associated with tea and fruit flavor directions. A food-flavor project requires a suitable quoted grade and documents for its destination market; a fragrance grade is not automatically food grade.
Commercial Grade & Specification
Theaspirane is traded in more than one commercial grade. A ≥97.0% combined-isomer assay and 25 kg/drum packing are reference trade specifications; final assay, analytical method, available packing and batch details are confirmed for the actual material quoted.

Theaspirane FAQ
What does Theaspirane smell like?
Theaspirane has tea-like, leafy-green, woody and herbal nuances, often with cool minty or camphoraceous facets. Its odor is more complex than a simple sweet tea scent.
Does CAS 36431-72-8 refer to an isomer mixture?
Commercial Theaspirane under this CAS is commonly a stereoisomer mixture. Assay may be expressed as the total of relevant isomers. Specify any required isomer profile in the quotation request.
Are Theaspiran and Spiroxide related names?
Yes. Theaspiran is a common synonym, while Spiroxide also appears in trade usage. CAS 36431-72-8 identifies the chemical, but commercial specifications may differ.
Is Theaspirane a tea extract?
No. It is a defined aroma chemical, although the substance has been reported among the volatile compounds of natural materials. Commercial origin depends on the quoted product.
Can Theaspirane be used in food flavors?
Theaspirane is listed as a flavoring substance in JECFA information. A particular commercial material still needs the correct grade, documentation and end-market suitability for its proposed food or beverage application.
What is the commercial packing size?
A 25 kg drum is a published commercial packing reference. Available pack sizes and minimum order terms are confirmed in the quotation.
Can I request an SDS or batch COA?
