Description

Hydrogenated Raspberry Seed Oil is a refined oil derived from the seeds of the raspberry (Rubus idaeus). The oil undergoes a hydrogenation process to convert its unsaturated fats into saturated fats, which stabilizes the oil and extends its shelf life. This ingredient is used in cosmetics for its emollient, moisturizing, and nourishing properties.

Chemical Composition and Structure:

Key Components:
Fatty Acids: Includes a mix of saturated and unsaturated fatty acids, with a higher concentration of saturated fats due to hydrogenation. Key fatty acids include linoleic acid and oleic acid.
Vitamins: Contains vitamin E, an antioxidant that helps protect the skin.
Structure: The oil has a higher melting point and a more solid consistency compared to non-hydrogenated raspberry seed oil due to the hydrogenation process.

Physical Properties:

Appearance: Typically a light yellow to pale amber solid or semi-solid at room temperature, depending on the extent of hydrogenation.
Odor: Mild, characteristic of raspberry seeds.
Texture: Smooth and non-greasy, easily absorbed by the skin.

Production Process:

Extraction: Raspberry seeds are cold-pressed to obtain raspberry seed oil.
Hydrogenation: The oil is hydrogenated using hydrogen gas and a catalyst to convert unsaturated fatty acids into saturated fatty acids. This process solidifies the oil and improves its stability.
Refinement: The hydrogenated oil is refined to remove any impurities and improve its quality.

Applications:

Moisturizing: Provides deep hydration and helps to restore the skin’s natural barrier.
Emollient: Softens and smooths the skin, improving its texture and appearance.
Nourishing: Rich in essential fatty acids and vitamins that support skin health and regeneration.

Safety and Environmental Considerations:

Safety: Hydrogenated raspberry seed oil is generally considered safe for use in cosmetics and personal care products. However, individuals with allergies to raspberry seeds should be cautious.
Environmental Impact: The hydrogenation process is designed to improve the stability of the oil, potentially reducing the need for preservatives and extending the product's shelf life.

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.
