Summary

Exfoliant Antioxidant Skin conditioning Nourishing

Science

Mechanism of Action

This ingredient functions primarily through gentle mechanical exfoliation, attributed to its natural plant fibers, which aids in refining skin texture and promoting a more uniform appearance. It inherently contains residual essential fatty acids, such as linoleic and alpha-linolenic acids, vital for skin hydration and barrier support. Furthermore, it retains a spectrum of antioxidants, including vitamin E and polyphenols, which combat oxidative stress and free radical damage, potentially mitigating visible signs of aging. It may also possess anti-inflammatory properties, contributing to the alleviation of skin irritation and redness.

Key findings

  1. 01 An ethanolic extract (3.125-100 mg/mL) from red raspberry seed waste exhibited significant radical-scavenging and antioxidant activity in a cell-based model, along with broad-spectrum antimicrobial action against spoilage and pathogenic bacteria. It also demonstrated antiproliferative activity against specific epithelial cancer cell lines in a dose-dependent manner.
  2. 02 Encapsulated raspberry powder (2-3% concentration), when incorporated into aerobically packaged ground beef, effectively suppressed microbial growth and inhibited lipid oxidation by up to 81.24%, indicating preservative capabilities.
  3. 03 Encapsulated raspberry powders (≥ 4.00%), when used in a food product (cemen paste), contributed to improved visual properties and color stability, particularly when the pH was acidified to 3.0-4.0.

Transparency

Dusting Analysis

Not commonly dusted

As a physical exfoliant, the presence of Rubus Idaeus Seedcake Powder is typically discernible even at lower concentrations. While its antioxidant and nourishing benefits may require a specific percentage for optimal efficacy, a 'dusting' claim is less applicable to its primary mechanical function. Specific topical efficacy concentrations are not detailed in current research.

Stability

Rubus Idaeus Seedcake Powder is a fine, gritty particulate largely composed of natural fibers, rendering it insoluble in both water and oil. Studies on related encapsulated raspberry powders in food products suggest that formulations maintained within an acidic pH range of 3.0-4.0 can contribute to improved stability of beneficial components.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Generally regarded as safe for cosmetic use, the raw material (Rubus Idaeus Seed) is considered non-toxic and well-tolerated across most skin types. Allergic reactions are uncommon; however, patch testing is advised for individuals with known sensitivities to raspberries or related botanical species. The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically assessed 'RUBUS IDAEUS SEEDCAKE POWDER,' though 'Rubus Idaeus (Raspberry) Seed Oil' has been reviewed.
