AVENA SATIVA BRAN EXTRACT.

Valuable CAS 84012-26-0 / ABRASIVE

A nutrient-rich botanical derivative sourced from the outer hull of the oat grain, specifically utilized for its high concentration of beta-glucans and soothing phenols. It functions as a sophisticated skin-conditioning agent that bridges the gap between topical hydration and biological barrier repair.

Summary

soothing moisturising antioxidant barrier support

Science

Mechanism of Action

The extract operates via a tripartite biological pathway. First, its high-molecular-weight beta-glucans form a non-occlusive, moisture-binding film that significantly reduces transepidermal water loss (TEWL). Second, specialized antioxidants known as avenanthramides suppress pro-inflammatory cytokine activity to mitigate redness and pruritus. Finally, its native omega-3 and omega-6 lipids integrate into the lipid bilayer while stimulating keratinocyte differentiation to strengthen the Epidermal Differentiation Complex.

Key findings

  1. 01 A 2019 clinical assessment (ICHIMAT) confirmed that a 7.5% concentration achieved the highest efficacy in treating xerosis, showing superior hydration markers compared to 2.5% and 5% formulations over a 28-day period.
  2. 02 The Cosmetic Ingredient Review (CIR) identifies 0.2% as a foundational concentration for providing localized anti-inflammatory and soothing benefits in leave-on applications.

Dusting Analysis

Red flag below
0.1%

Due to its high marketing appeal, oat-derived ingredients are frequently 'dusted' at concentrations below 0.1%. While these levels allow for label claims, they fail to trigger the anti-inflammatory response or provide the film-forming hydration benefits validated in clinical trials.

Stability

Thermo-sensitive extract; prolonged exposure to temperatures exceeding 40°C will degrade bioactive beta-glucans. Should be incorporated during the cool-down phase of emulsion manufacturing.

Synergies

  • Humectants (Glycerin, Hyaluronic Acid)
  • Barrier-repair lipids (Ceramides)

Conflicts

  • Extreme pH environments (below 4.0 or above 7.0)
  • High-heat processing
