Description

Hazelnut Seed Oil Polyglyceryl-6 Esters is the product obtained by the transesterification of Corylus avellana (Hazelnut) Seed Oil and Polyglyceryl-6. This compound is widely used in the cosmetic industry for its emulsifying, moisturizing, and skin-conditioning properties.

Chemical Composition and Structure

Hazelnut Seed Oil Polyglyceryl-6 Esters is composed of esters formed from the fatty acids in hazelnut seed oil and Polyglyceryl-6. The combination of these components provides excellent emulsifying properties and enhances the hydrating and nourishing effects on the skin.

Physical Properties

Hazelnut Seed Oil Polyglyceryl-6 Esters typically appears as a clear to pale yellow liquid with a mild nutty aroma. It is soluble in oils and other lipophilic substances but has limited solubility in water, 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 seed oil.
Oil Extraction: The oil is extracted from the hazelnut seeds using methods such as cold pressing or solvent extraction.
Transesterification: The extracted oil undergoes a transesterification process with Polyglyceryl-6. This process involves reacting the fatty acids in the oil with Polyglyceryl-6 in the presence of a catalyst under controlled 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 esters, including chemical and microbiological analyses.

Applications

Cosmetic Products: Used in creams, lotions, and serums for its emulsifying and moisturizing properties, improving the texture and hydration of the skin.
Skin Care: Ideal for products aimed at providing long-lasting moisture and enhancing skin smoothness without a greasy feel.
Hair Care: Incorporated into conditioners, hair masks, and treatments for its ability to provide nourishment and manageability to the hair.
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

Hazelnut Seed Oil Polyglyceryl-6 Esters 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 - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.

Surfactant - Emulsifying agent. Emulsions are thermodynamically unstable and are used to soothe or soften the skin and emulsify, so they need a specific, stabilising ingredient. This ingredient forms a film, lowers the surface tension and makes two immiscible liquids miscible. A very important factor affecting the stability of the emulsion is the amount of the emulsifying agent. Emulsifiers have the property of reducing the oil/water or water/oil interfacial tension, improving the stability of the emulsion and also directly influencing the stability, sensory properties and surface tension of sunscreens by modulating the filmometric performance.

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.

Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
