3-sh-Polypeptide-9

Product Description

Green Stone Swiss supplies high-purity sh-Polypeptide-9 manufactured under GMP-aligned biotechnology controls for consistent identity, potency documentation, and reliable bulk availability. Our direct factory supply model supports premium skincare and scalp-care brands with COA/TDS packages, technical guidance, and free sample evaluation for peptide system development.

sh-Polypeptide-9 is a single-chain recombinant human peptide produced by microbial fermentation from a synthesized gene coding for Vascular Endothelial Growth Factor A (VEGF-A). In CosIng it is listed as a skin conditioning agent. In cosmetic use it is positioned as a signal peptide that supports microcirculation-related nutrient delivery narratives, cell vitality, tissue comfort recovery, and scalp follicle vitality concepts in leave-on serums and growth-factor complexes.

Demand continues to rise for recombinant growth-factor peptides in anti-aging serums, eye care, post-care recovery textures, and hair-scalp vitality systems. High-purity sh-Polypeptide-9 offers a clear INCI story and factory-direct supply for brands building multi-peptide and bio-signal platforms.

Key Benefits & Applications

sh-Polypeptide-9 is a recombinant VEGF-pathway signal peptide used in advanced skin vitality, firming, and scalp-care peptide systems.

• Supports microcirculation-related nutrient delivery narratives for skin vitality formulas
• Helps position anti-aging and firming serums with cell-signaling and recovery storytelling
• Useful in post-care comfort textures targeting tissue recovery appearance
• Supports scalp and hair follicle vitality concepts in leave-on hair-scalp serums
• Ideal for multi-peptide cocktails, eye care, essences, and bio-signal moisturizers
• Suggested use level: Typical via diluted stock solutions (commonly referenced stock use 1–10%; confirm active ppm with TDS)

Formulation Guidelines

Protect bioactivity by reconstituting carefully and adding sh-Polypeptide-9 late in cool-down under mild pH conditions.

• Suggested Use Level: Available upon request; Typical practice uses a reconstituted stock then doses to target active level per TDS
• pH Range: Suggested 5.0–7.0 in aqueous systems; avoid extreme acid/alkali that may denature the protein
• Addition: Reconstitute in sterile water; add during cool-down preferably below 40°C
• Compatibility: Avoid strong oxidizers, high heat, and repeated freeze–thaw of reconstituted aliquots
• Stability: Keep lyophilized material cold and dry; validate peptide integrity after accelerated stability testing
• Combine with Alanine Histidine Lysine Polypeptide Copper Hcl for complementary peptide synergy in repair-oriented anti-aging systems.
