HORDEUM VULGARE LEAF/STEM POWDER.

Insufficient Data CAS 85251-64-5 / ANTIOXIDANT

Hordeum Vulgare Leaf/Stem Powder, derived from barley, acts as a multi-functional botanical ingredient. It provides antioxidant protection against environmental stressors, conditions the skin, and functions as a humectant to enhance moisture retention. Its broad benefits contribute to overall skin health and vitality.

Summary

Humectant Skin conditioning Antioxidant Soothing Anti-aging

Science

Mechanism of Action

This ingredient operates as a potent antioxidant, neutralizing free radicals and shielding the skin from oxidative damage induced by pollution and UV radiation. It serves as a skin conditioning agent, supporting overall skin health and maintaining its balanced state. As a humectant, it effectively draws and retains moisture within cosmetic formulations and on the skin's surface, contributing to improved hydration. Furthermore, it strengthens the skin barrier and offers soothing properties by modulating gene expression and potentially reducing inflammation, which can alleviate redness. In vitro studies demonstrate its capacity to stimulate Extracellular Matrix (ECM) components like fibroblast proliferation, collagen, elastin, and hyaluronic acid synthesis, while also inhibiting Matrix Metalloproteinase-1 (MMP-1), MMP-2, and MMP-9, thereby supporting skin repair and exhibiting anti-aging potential. Components like hordein may also suppress melanin synthesis, and it enhances DNA biosynthesis in UV-radiated fibroblasts.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that there is insufficient data to determine the safety of non-seed Hordeum Vulgare ingredients, including Leaf/Stem Powder, as used in cosmetics. They specifically requested 28-day dermal toxicity data on whole plant extracts and dermal irritation/sensitization data at maximum use concentrations. While generally well-tolerated, individuals sensitive to grains should be aware that barley is a source of gluten. It is important to distinguish that while a general Hordeum Vulgare Extract has been reported safe up to 1.5% in leave-on products, and an eye cream at 0.005% was non-irritating, a specific maximum safe concentration for this particular Leaf/Stem Powder form has not been established by CIR.

Verdict

Insufficient Data

While Hordeum Vulgare Leaf/Stem Powder demonstrates promising in-vitro benefits for skin protection and repair, the Cosmetic Ingredient Review (CIR) Expert Panel has determined there is insufficient safety data specifically for this form, necessitating further research for confident cosmetic use.
