Glycine Soja (Soybean) Protein

Product Description

Glycine Soja (Soybean) Protein is a high-purity, plant-derived peptide complex manufactured in our ISO-certified facility, ensuring consistent quality for direct global B2B supply. This ingredient functions through a biomimetic mechanism, acting as a natural protease inhibitor that prevents the breakdown of elastin and collagen fibers while providing a film-forming effect to stabilize the skin barrier. As the personal care market shifts toward "Vegan Beauty" and "Clean Label" trends, this soy-based protein offers a sustainable, high-performance solution for reparative and anti-aging formulations.

Product Specification

• INCI Name: Glycine Soja (Soybean) Protein
• CAS No.: 9010-10-0 / 9001-22-3
• Botanical Source: Glycine soja (Non-GMO Soybean)
• Appearance: Light yellow to amber transparent liquid / Off-white powder
• Protein Content: ≥ 90% (Dry matter basis for powder)
• Molecular Weight: 1,000 - 3,000 Da (Optimized for Dermal Penetration)

Key Benefits & Applications

• Protease Inhibition: Effectively inhibits elastase and collagenase activity, preserving the extracellular matrix (ECM) and enhancing skin elasticity.
• Barrier Function Enhancement: Forms a breathable, semi-permeable film on the stratum corneum, reducing trans-epidermal water loss (TEWL) and protecting against environmental stressors.
• Irritancy Mitigation: Clinically utilized to reduce the irritation potential of surfactants and environmental pollutants, making it ideal for sensitive skin profiles.
• Applications: Extensively used in anti-wrinkle serums, barrier-repairing emulsions, under-eye treatments for puffiness reduction, and high-end hair care for cuticle smoothing.

Formulation Guidelines

• Recommended Dosage: 1.0% – 5.0% for leave-on products; 0.5% – 2.0% for rinse-off applications.
• pH Stability: Maintains functional integrity within a pH range of 4.0 – 7.0.
• Processing: Add to the aqueous phase or at the end of the emulsification process (below 45°C) to maintain peptide bioactivity.
• Synergy: Combine with Sodium Hyaluronate for enhanced multi-layer hydration and long-lasting skin smoothness.
