Science
Mechanism of Action
This ingredient primarily acts as a skin conditioning agent, improving the skin's overall feel and appearance. While specific mechanistic details for the ester are limited, it is derived from Corylus Avellana Seed Oil (Hazelnut Oil), which is recognized for its emollient, moisturizing, and barrier-restoring capabilities. It is also believed to possess astringent, antioxidant, and collagen-protective properties, with potential benefits for sebum regulation, acne, cell regeneration, and hyperpigmentation, though these effects are not directly proven for the decyl ester.

Stability
The optimal pH range for stability of Hazelnut Seed Oil Decyl Esters is not precisely known. As a decyl ester, it exhibits oil solubility. For optimal longevity, it should be stored in tightly sealed containers at room temperature, protected from light and moisture.
Safety
Safety Profile
Hazelnut Seed Oil Decyl Esters has not undergone a specific safety review by the CIR Expert Panel. However, a broader class of 237 alkyl esters, which includes decyl esters, was concluded to be safe in cosmetic formulations at current use concentrations, provided they are formulated to be non-irritating. While a separate CIR report for hazelnut oil and its extracts indicated insufficient data, one comedogenicity study on hazelnut seed oil reported negative results. There are noted concerns regarding possible aflatoxin contamination in raw hazelnuts, which is typically addressed during the processing of cosmetic-grade ingredients.
