ETHYL HEPTANOATE.

Valuable CAS 106-30-9 / PERFUMING

Ethyl Heptanoate is an ester primarily utilized for its solvent properties, facilitating the uniform dispersion of other ingredients within a formulation. It also imparts a distinctive fruity fragrance to products and may contribute to skin conditioning through emollient action.

Summary

Emollient Solvent Perfuming

Science

Mechanism of Action

As an ester, Ethyl Heptanoate acts fundamentally as a solvent, assisting in the dissolution and even distribution of various active and inactive components within a skincare matrix. Concurrently, it functions as a perfuming agent, delivering a characteristic fruity note. Its molecular structure may also enable it to form a protective film on the skin's surface, thereby offering mild emollient benefits that contribute to skin softness and smoothness.

Stability

Ethyl Heptanoate exhibits general stability under typical formulation conditions. However, its ester bond is susceptible to hydrolysis when exposed to strong acidic or basic environments, which can degrade it into heptanoic acid and ethanol. It has demonstrated stability and non-discoloring properties across a range of cosmetic applications, including creams, lotions, and hair products.

Safety

Safety Profile

CIR Status
Not reviewed
Max tested
2.2%
Sensitization risk Low

Safety assessments by the Research Institute for Fragrance Materials (RIFM) indicate low toxicity via ingestion and skin contact. While human maximization tests at 4% and 8% in petrolatum did not induce skin sensitization, RIFM notes a potential for sensitization in a small subset of individuals, with a No Expected Sensitization Induction Level (NESIL) of 4700 μg/cm². Maximum acceptable concentrations in finished products, guided by RIFM and IFRA standards, vary by application: 0.36% for lip products, 0.11% for products applied to the axillae, and 2.2% for products intended for face/body application via fingertips. Ethyl Heptanoate is not considered genotoxic, phototoxic, or photoallergenic. The FDA recognizes it as Generally Recognized As Safe (GRAS) for use as a synthetic flavoring in food.
