Tealactone (CAS 15356-74-8) — Green Top to middle Note Fragrance Ingredient
Tealactone
CAS 15356-74-8
What Is Tealactone?
Tealactone is a synthetic fragrance ingredient used to create fresh, aquatic, and marine accords in modern perfumery. You’ll encounter it in ocean-inspired body sprays, men’s colognes, and some fabric softeners. This versatile molecule helps perfumers mimic the crisp, clean scent of sea air without relying on natural extracts, making fragrances more sustainable and consistent.
Safety Profile
GENERALLY SAFEWhat Does Tealactone Smell Like?
Tealactone bursts open with an exhilarating ozonic freshness – like the first breath of sea wind hitting a sun-warmed dock. Within minutes, it evolves into a sophisticated marine heart: imagine crushed seaweed drying on hot rocks, with a subtle musky-sweet undertone reminiscent of ambergris. The dry-down reveals a whisper of salt-crusted driftwood, leaving a clean, slightly mineralic trail that lingers close to the skin.

Chemistry, Properties & Perfumer Guide
The Chemistry
Tealactone belongs to the class of macrocyclic lactones, though its exact structure remains proprietary in the fragrance industry. It’s produced through controlled oxidation processes of specific hydrocarbon precursors, often involving catalytic cyclization reactions. Unlike many marine fragrance chemicals, Tealactone lacks the sulfurous notes commonly associated with this olfactory family, achieving its aquatic character through careful balancing of ozonic and musky facets.

Classic Accords
Tip: Use with citrus top notes to prevent the marine character from becoming too dominant.
Alternatives & Comparisons
More intense watermelon-metallic marine effect, use when higher diffusion is needed.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
No restrictions under current IFRA standards.
RIFM Assessment
Considered safe for use in current applications based on RIFM evaluation.
Sustainability
As a synthetic material, Tealactone reduces pressure on marine ecosystems compared to natural ambergris sourcing. Modern production methods aim to minimize solvent waste and energy consumption. The material’s potency means very small quantities are needed in formulations, reducing overall environmental footprint.
