Rubus Idaeus Seedcake Powder is a fine powder derived from the cake or residue left after the extraction of oil from raspberry seeds (Rubus idaeus). It is used in cosmetic and skincare formulations for its exfoliating, soothing, and nourishing properties.

Chemical Composition and Structure:

Main Components:
Fibers: Contains natural plant fibers that provide gentle exfoliation and help improve skin texture.
Essential Fatty Acids: Retains some beneficial fatty acids like linoleic acid and alpha-linolenic acid from the seeds, which contribute to skin hydration and nourishment.
Antioxidants: Includes residual antioxidants such as vitamin E and polyphenols, which help protect the skin from oxidative stress.
Vitamins and Minerals: Contains trace amounts of vitamins A, C, and minerals that support skin health.
Structure: The powder is a fine, gritty substance with a slightly fibrous texture, which makes it suitable for use in exfoliating products.

Physical Properties:

Appearance: Typically a beige to light brown powder.
Odor: May have a subtle, natural, nutty aroma characteristic of raspberry seeds.
Texture: Fine and gritty, ideal for gentle exfoliation.

Production Process:

Oil Extraction: Raspberry seeds are cold-pressed or mechanically extracted to obtain Rubus Idaeus Seed Oil, leaving behind the seedcake.
Powdering: The residual seedcake is dried and ground into a fine powder.
Processing: The powder may be sifted and treated to ensure uniform particle size and quality.

Applications:

Exfoliation: Provides a gentle abrasive action for exfoliating dead skin cells, helping to improve skin texture and promote a smoother appearance.
Nourishing: Offers residual nutrients and fatty acids that contribute to skin hydration and health.
Soothing: May have calming effects on the skin, reducing irritation and inflammation.

Safety and Environmental Considerations:

Safety: Rubus Idaeus Seedcake Powder is generally regarded as safe for use in cosmetic and personal care products when used as directed. Individuals with raspberry allergies or very sensitive skin should exercise caution.
Environmental Impact: Utilizing the by-product of oil extraction can be considered environmentally friendly, as it reduces waste and makes use of the entire seed.

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.
