Coffee Seed Oil PEG-8 Esters is a derivative of Coffea arabica seed oil modified with PEG-8 esters. This ingredient combines the benefits of coffee seed oil with the solubility and stability provided by PEG-8 esters, making it a versatile component in various cosmetic formulations.

Chemical Composition and Structure

PEG-8 Esters: These esters are polyethylene glycol derivatives that enhance the solubility of oil-based components in water-based formulations.
Coffee Seed Oil Components: Includes caffeine, chlorogenic acids, and essential fatty acids, which provide antioxidant, anti-inflammatory, and moisturizing benefits.
The combination of PEG-8 esters with coffee seed oil improves the stability and ease of use in cosmetic products.

Physical Properties

Appearance: Usually a clear to light brown liquid.
Odor: Characteristic coffee aroma.
Solubility: Soluble in water and water-based solvents due to the PEG-8 esters.
Texture: Light and non-greasy, facilitating easy application and absorption.

Production Process

Harvesting: Seeds of Coffea arabica are collected.
Extraction: Coffee seed oil is extracted from the seeds.
Reaction: The coffee seed oil is reacted with PEG-8 to produce esters.
Filtration: The resulting esters are filtered to remove impurities.
Packaging: The final product is packaged to preserve its stability and efficacy.

Applications

Cosmetic: Used in skincare and personal care products to enhance formulation stability, improve solubility, and provide moisturizing benefits. Often found in creams, lotions, and serums.
Pharmaceutical: May be used in topical formulations for its hydrating and soothing properties.
Food: Not typically used in food products.

Environmental and Safety Considerations

Biodegradability: The esters are designed to be environmentally friendly and biodegradable.
Toxicity: Generally considered safe for topical application. However, it should be used in accordance with established guidelines to avoid potential allergic reactions or skin irritations. People with allergies or very sensitive skin should exercise caution. It is important to ensure that the esters are sustainably sourced and free from harmful chemicals.
Disposal: Should be disposed of in accordance with local environmental regulations to minimize environmental impact.

INCI Functions:


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.
