01The brief.

Origin

Silk cocoons from Chinese and Korean sericulture, hydrolysed and standardised in South Korean cosmetic-biotech facilities to guarantee peptide weight.

Extraction

Cocoons are degummed to isolate fibroin (the structural protein — sericin is the gum), then enzymatically hydrolysed to a controlled 500–1,200 Da range.

Concentration

1%–3% in rinse-off and leave-in formulas.

02How it works.

Hydrolysed silk peptides deposit in a thin, water-resistant film along the cuticle. Their block-copolymer structure (alternating hydrophilic and hydrophobic domains) lets them bond to damaged patches while remaining flexible enough to move with the strand — the reason silk-treated hair looks glossy but never crunchy.

  • Benefits
  • ✦Coats and smooths the cuticle for a mirror-like finish
  • ✦Adds tensile strength to bleach-weakened strands
  • ✦Improves colour retention by sealing porosity
  • ✦Lightweight — no protein-overload stiffness

03Molecular signature.

The active constituents that make Hydrolyzed Silk work — with standardised percentages where measured by HPLC.

  • Fibroin peptides

    Repeating glycine-alanine-serine block — the crystalline core of silk.

  • Hydrophobic domains

    Bind to damaged hydrophobic patches on the cuticle.

The record

Sericulture began in China around 3,600 BCE; hydrolysed silk peptides for cosmetic use were commercialised in Japan and Korea in the 1970s–80s as an alternative to animal-derived collagen.

Traditional use

Chinese and Japanese silk-water hair rinses; Ayurvedic silk-fibre scalp massage.

Naturally found in

  • ●Bombyx mori silkworm cocoons (main source)
  • ●Wild silk (tussar, muga) cocoons in India — different amino profile

Sustainability

Peace Silk protocols allow moths to emerge before cocoon harvest, addressing the ethical concern. Cocoons are otherwise agricultural by-products.

09People often ask.

Hydrolyzed silk vs silk amino acids?

Silk amino acids are the smallest fragments (single amino acids and dipeptides); hydrolysed silk is a slightly larger peptide range that films the cuticle. We use both for complementary repair.
