HEPTANOIC ACID.

Avoid CAS 111-14-8 / PERFUMING

Heptanoic acid functions as an emollient and moisturizer, contributing to skin smoothness and hydration. However, its primary cosmetic utility is as a perfuming agent, with concentrated forms exhibiting significant corrosive and irritating properties.

Emollient Moisturizer Perfuming

Science

It operates by forming an occlusive barrier on the skin's surface, effectively softening and conditioning the skin. This action enhances hydration and promotes a smoother tactile texture, consistent with emollient functionality.

Safety

CIR Status
Not reviewed
Sensitization risk High

While an ester derivative, Stearyl Heptanoate, has been assessed and deemed safe by the CIR Expert Panel, Heptanoic Acid itself lacks a direct CIR safety assessment for cosmetic application. Concentrated forms are classified as corrosive, capable of causing severe skin burns and eye damage, and are harmful if inhaled, potentially leading to respiratory irritation.

Our Assessment

Avoid

Due to its high irritancy potential, lack of direct CIR safety review for its use as a cosmetic ingredient, and severe corrosive risks in concentrated forms, Heptanoic Acid is not recommended for precision skincare formulations.
