Lauryl acetate (CAS 112-66-3) — Sweet Middle to base Note Fragrance Ingredient
Lauryl acetate
CAS 112-66-3
What Is Lauryl acetate?
Lauryl acetate is a synthetic fragrance ingredient commonly used in perfumes, soaps, and household products for its fresh, fruity, and slightly floral aroma. You’ll encounter it in personal care items where a light, clean scent is desired. This ester is valued for its ability to add a subtle yet long-lasting freshness to fragrances without overwhelming the composition. It blends seamlessly with other ingredients to create balanced, approachable scents for everyday products.
Safety Profile
GENERALLY SAFEWhat Does Lauryl acetate Smell Like?
Lauryl acetate presents a delicate bouquet that unfolds like morning dew on citrus peel – initially bright and slightly tart, then softening into a creamy, fruity heart reminiscent of pear drops and fresh laundry. The dry-down reveals a whisper of floral character, like distant gardenias, before settling into a clean, musky base that lingers close to the skin. Its volatility creates a gentle diffusion rather than sharp projection, making it ideal for intimate fragrances where subtlety is key.

Chemistry, Properties & Perfumer Guide
The Chemistry
Lauryl acetate is a straight-chain fatty acid ester formed by the condensation of lauryl alcohol and acetic acid. As a synthetic material, it’s typically produced through esterification under acid catalysis. The molecule’s twelve-carbon chain provides excellent substantivity on skin while the acetate group contributes volatility. Its linear structure lacks chirality, ensuring consistent olfactory properties across production batches. The ester’s hydrophobicity (predicted XLogP ~4.5) makes it particularly useful in oil-based fragrance formulations.

Classic Accords
Tip: Use as a bridge between citrus top notes and floral heart notes to prevent harsh transitions.
Alternatives & Comparisons
When a less fruity, more waxy character is desired. Lacks the acetate’s fresh top note but provides similar substantivity.
For a similar but more volatile fruity note in top-heavy compositions where faster evaporation 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 current fragrance uses based on RIFM’s 2020 ester group evaluation.
Sustainability
As a fully synthetic material, lauryl acetate’s production avoids agricultural impacts but depends on petrochemical feedstocks. Modern manufacturing employs green chemistry principles to minimize waste and energy use. Being biodegradable and of low aquatic toxicity, it poses minimal environmental risk at typical usage levels.
