Description

Corylus Avellana Ethyl Ester is the ethyl ester of the fatty acids derived from the Hazelnut, Corylus avellana L., belonging to the Betulaceae family. This ester is commonly used in the cosmetic and personal care industries for its emollient and moisturizing properties.

Chemical Composition and Structure

Corylus Avellana Ethyl Ester is composed of ethyl esters of the fatty acids present in hazelnut seed oil. These fatty acids primarily include oleic acid and linoleic acid, which contribute to the product's emollient and moisturizing properties.

Physical Properties

Corylus Avellana Ethyl Ester typically appears as a clear, colorless to pale yellow liquid with a mild, nutty aroma. It is soluble in oils and alcohols but has limited water solubility, making it suitable for various oil-based and anhydrous formulations.

Production Process

Harvesting and Selection: Hazelnuts are harvested and carefully selected to ensure the quality of the oil from which the esters will be derived.
Oil Extraction: The oil is extracted from the hazelnut seeds using methods such as cold pressing or solvent extraction.
Esterification: The extracted oil undergoes an esterification process, where the fatty acids are reacted with ethanol to form ethyl esters. This process typically involves the use of a catalyst and controlled reaction conditions.
Purification: The resulting esters are purified to remove any unreacted materials and by-products, ensuring a high-quality final product.
Quality Control: Rigorous quality tests are conducted to evaluate the purity, stability, and composition of the ethyl esters, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, and serums for its emollient and moisturizing properties, enhancing skin hydration and texture.
Skin Care: Ideal for products aimed at providing long-lasting moisture and improving skin smoothness without a greasy feel.
Hair Care: Incorporated into conditioners, hair oils, and treatments for its ability to provide shine and manageability to hair without weighing it down.
Personal Care Products: Used in various formulations such as body oils, bath oils, and lip care products for its lightweight and non-greasy emollient properties.

Environmental and Safety Considerations

Corylus Avellana Ethyl Ester is considered safe for use in cosmetic and personal care products and is generally well-tolerated by the skin. It is non-irritating and suitable for all skin types, including sensitive skin. Proper use within recommended concentrations is essential to ensure safety and maximize effectiveness. Additionally, the sustainability of hazelnut cultivation and oil production practices is an important consideration to ensure environmental responsibility.

INCI


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
