High-purity raw extracts and premium formulations manufactured under strict international standards to boost skin and wellness solutions.
Silk Amino Acids (SAA), also designated as Sericin or Fibroin hydrolysates, are highly sought-after bioactive nitrogen complexes obtained from pure raw silk cocoons. With a natural abundance of Glycine, Alanine, and Serine, these micro-peptides possess the unique structural capability to penetrate the skin barrier and hair cuticle deeper than standard collagen derivatives.
At Shaanxi Bieyouth Biotech Co., Ltd., we utilize advanced enzymatic hydrolysis rather than harsh acid extraction. This targeted degradation preserves the biochemical integrity of the peptides, delivering structural compounds with a targeted molecular weight of 300 to 2000 Daltons. These low molecular fragments optimize water solubility and bioavailability, making them indispensable in clean clinical cosmetics and high-performance hair care formulations.
A trusted global supplier integrating premium plant extracts, nutritional additives, and high-performance cosmetic raw materials since 2018.
Established in 2018, Shaanxi Bieyouth Biotech Co., Ltd. operates with decades of cumulative engineering experience in the global chemical and botanical distribution markets. As an industry-leading gold supplier, we integrate scientific extraction, purification, quality assurance, and global logistics under one umbrella. Our GMP-certified manufacturing facilities feature dual standardized production workshops and state-of-the-art fractional distillation and extraction chambers.
Through dedicated research partnerships and stringent analytical testing, our exports have penetrated high-demand markets across the United States, the United Kingdom, Canada, Russia, Australia, and various countries within the EU and Asia-Pacific region.
Pioneering cleaner chemistry, lower carbon footprint, and controlled peptide distribution profiles.
Moving away from acid/alkaline digestion. Our factory uses targeted biological enzymes to cleave silk proteins at specific peptide bonds, resulting in highly consistent peptide batches without environmental waste.
Using ultra-filtration and nanofiltration membranes to narrow the molecular weight distribution. This isolates specific molecular sizes tailored to skin permeability or hair binding properties.
Transitioning toward carbon-neutral agricultural sourcing. We repurpose byproduct streams from local silk farms, creating a sustainable production process from cocoon extraction to active ingredient powder.
Tailored formulations to meet the diverse demands of cosmetic, pharmaceutical, and high-performance sectors.
Silk Amino Acids act as structural foundations for skin cell repair. Their low molecular weight allows deep penetration into the stratum corneum, supporting natural collagen synthesis and boosting hydration in anti-aging creams, serums, and toners.
Highly effective in restoring split ends and dry cuticles, our hydrolyzed silk peptides lock onto hair keratin. They form a protective sheath that shields hair from environmental and heat styling damage while restoring natural bounce and gloss.
Rich in bioavailable amino acids, our silk extracts provide premium protein supplements with direct bioavailability. Ideal for functional sports nutrition powders, anti-fatigue beverages, and dietary tablets.
Leveraging advanced production control and modern supply networks to deliver high-quality ingredients worldwide.
Our extraction facilities operate with fully automated process control systems. This maintains precise temp, pH, and flow metrics across all production runs, ensuring consistent batch quality.
We source raw cocoons directly from domestic silk farming cooperatives. This direct procurement shields our factory from market supply shortages, providing stable material supply and predictable pricing.
Strategically situated near central transport corridors, our facility offers rapid dispatch to domestic seaports and international cargo routes. We maintain safety stock levels for strategic clients to ensure on-time deliveries.
