What is Cyclodumol Acetate?

Cyclodumol Acetate is a synthetic ester built from terpene derivatives, particularly designed as part of a new class of biodegradable aroma materials. Developed by Symrise, it is manufactured from crude sulfate turpentine (CST) — a renewable byproduct of the pulp and paper industry.

The ingredient was introduced at SIMPPAR 2022 as part of a sustainability initiative and reflects the growing industry trend toward renewable carbon sources and environmentally safer materials. Its renewable factor (83%) and biodegradability (66%) are based on standardized testing (OECD-ready biodegradability).

Despite its ecological advantages, it also stands out olfactorily for its soft, floral complexity and musky undertone.

Olfactory Profile and Perfumery Applications

Cyclodumol Acetate delivers a floral-fruity scent with an emphasis on geranium leaf, pear, and rose, with a subtle musky-damascone undertone that enhances floral volume and adds diffusive power to top notes.

It functions as:

• A diffusion booster in floral and green compositions

• A floral volume enhancer, especially in body care, soaps, and soft musks

• A green harmonizer that softens and balances aromatic materials

Best suited for:

• Floral bouquets

• Herbal-citrus compositions

• Fruity-floral top accords (pear, rose, apple-like effects)

Industrial and Technical Uses

Although designed primarily for fine and functional perfumery, Cyclodumol Acetate has also found application in:

• Soaps and cleansers (for its biodegradable profile)

• Personal care products requiring floral lift with reduced ecological impact

• Detergent-friendly green fragrance solutions

It is not approved for food use and not listed in FEMA GRAS databases.

Regulatory and Safety Overview

• IFRA: Not restricted under the 51st Amendment. Use according to standard safety assessment.

• EU Allergen Listing: Not among the 26 declarable allergens under Regulation (EC) No 1223/2009.

• FEMA GRAS: Not listed for flavor use or ingestion.

• ECHA: Not classified as hazardous under CLP. REACH-compliant raw material sourcing.

• Sustainability:

  • Renewable Carbon Index (RCI): 83%

  • Ready Biodegradability: 66% (OECD standards)

• Toxicology: No known sensitization or mutagenicity at recommended usage levels. Stable in formulation.

✅ Cyclodumol Acetate is a biodegradable, renewable alternative for sustainable fragrance formulation.

The 83% renewable-based ingredient cyclodumol acetate is a clear colorless to pale yellow liquid, suitable for application in small dosages or as filling material up to 8% as per Symrise's suggestions.
