Methyl Cedryl Ether
Chinese name: 甲基柏木醚
English name: Methyl Cedryl Ether
CAS No.: 67874-81-1/19870-74-7
Key Characteristics
This is the most essential and invaluable characteristic of methyl cedryl ether. Though its own odor intensity is modest, methyl cedryl ether can dramatically lift, brighten, and expand the performance of other materials—especially dense woody notes like cedarwood, patchouli, and musk. It makes a fragrance more transparent, spacious, and diffusive, as if the entire composition has been “illuminated”.
This ingredient delivers a persistent and gentle woody base infused with nuances reminiscent of natural ambergris and soft musk. The scent is refined, clean, noble, and approachable—an indispensable cornerstone of modern amber compositions.
Its aroma molecules possess moderate volatility, allowing rapid diffusion into the surrounding space while maintaining impressive persistence, making it a premium fixative.
Highly resistant to light, heat, acids, and alkalis, it is suitable for a broad range of product systems. It integrates well with nearly all fragrance types, especially woody, amber, musky, and oriental accords.
Primary Applications
A “finishing touch”: A crucial auxiliary component in nearly all fragrance families (chypre, fougère, oriental, and woody), enhancing the transparency and diffusion of the middle and base notes, and preventing heaviness.
Building ambergris accords: One of the core materials for recreating the effect of costly natural ambergris.
Men’s fragrances: When paired with sandalwood, patchouli, and leather notes, it lends buoyancy and lift without compromising heavy and masculine accords.
In premium shampoos, shower gels, and body lotions: Delivers a long-lasting, luxurious woody–musky background.
Soap Fragrances：Improves the longevity of scent in soap-based products thanks to its exceptional stability.
When used in premium candles, room sprays, and diffuser stones, its superior diffusivity allows the fragrance to fill the space quickly and evenly.
Usage Recommendations and Precautions
Dosage: As a lifting and modifying agent, its dosage is usually modest—0.5% to 3% in the final fragrance is sufficient to generate a notable effect. When used as part of an ambergris-focused theme, the dosage may be moderately increased.
Safety: It is considered safe for use under IFRA standards.
- Enhancing woody notes: When blended with cedarwood oil, patchouli, cedar, sandalwood, and similar materials, it instantly renders the woody accord lighter and more expansive.
- Building ambergris structures: Combined with ambroxides and cashmeran, it creates complex, long-lasting, and contemporary ambergris effects.
- Rounding musks: When used with various musk materials, it adds naturalness and depth.
- Enhancing citrus notes: Even in small amounts, it can heighten freshness and improve longevity in citrus top notes.
