Honey Bee Defensin-1 is a potent bee-derived antimicrobial peptide supplied as recombinant sr-Honey Bee Defensin-1 - a vegan, bio-identical alternative studied for keratinocyte MMP-9 migration and defensin-class antimicrobial / antibiofilm positioning in cosmetic literature.*
We ship recombinant sr-HBD-1 in a stabilizing aqueous suspension at two strengths - standard 1X (0.02%) for typical cosmetic dilution workflows, or a 5X lab concentrate (0.1%) when you want five times the protein loading in the same pack. The suspension helps protect the active during refrigerated storage and reduce deterioration - see SDS for composition details.*
These attributes are assessments based on the ingredient deck and the supplier information available to us. They are not third-party certifications. If your finished product requires a specific certified status, please reach out and we’ll walk through what we can document.
Every lot is produced to order in our AI-powered robotic factory. Nothing sits on a warehouse shelf going stale - you get a date-of-manufacture-fresh batch every time.

Bee defensin-1 (sr-Honey Bee Defensin-1) appears in keratinocyte MMP-9 / re-epithelialization studies and honeybee antimicrobial-peptide literature relevant to cosmetic barrier and microbiome positioning. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
Identifies recombinant bee defensin-1 as the royal-jelly factor that stimulates keratinocyte MMP-9 secretion and migration.
Reviews honey and other beehive products in skin-care and barrier-context literature, including keratinocyte and fibroblast work that frames defensin-class AMP positioning.

This is the bulk composition as it ships. Updates dynamically when you change the strength above. The active line shows the sr-HBD-1 loading at the selected concentration. Suspension stabilizers in the shipped bulk protect the active during storage and are not declared on the finished-product cosmetic INCI when the protein is reconstituted / diluted into your formula as directed. Full stabilizer identity and concentration are on the SDS.
SDS + TDS are issued per strength. Links swap when you change concentration above. COA is batch-specific and ships with the order.
