01The brief.

Origin

Sun-dried pods of Gleditsia sinensis, sustainably wild-harvested from the mountains of Sichuan and Hubei provinces.

Extraction

Whole dried pods (zào jiá) are simmered in soft water for 4 hours, filtered, and concentrated. Naturally rich in triterpene saponins that produce a mild, silky lather.

Concentration

3%–10% in cleansing formulas; often blended with modern surfactants for a balanced foam.

02How it works.

Gleditsia's triterpene saponins have an amphiphilic structure — one water-loving end, one oil-loving end. They surround sebum and dirt in the same way modern surfactants do, but because they're gentler and biodegradable, they leave the scalp's lipid barrier intact.

  • Benefits
  • ✦Cleanses without stripping the acid mantle
  • ✦Naturally low-foam — sulphate-free by design
  • ✦Adds slip and detangling to shampoo formulas
  • ✦Rooted in 2,000+ years of Chinese hair medicine

03Molecular signature.

The active constituents that make Gleditsia Extract work — with standardised percentages where measured by HPLC.

  • Gleditsia saponins

    Triterpene glycosides — the amphiphilic molecules that lift dirt without denaturing the cuticle.

  • Polysaccharides

    Add slip and reduce the perceived harshness of the cleanse.

  • Flavonoids

    Mild anti-inflammatory benefit for the scalp.

05Heritage.

The record

Documented as zào jiá in the Shen Nong Ben Cao Jing (2nd century BCE), Gleditsia pods were the 'shampoo' of imperial China for over two millennia — court ladies were said to have used them nightly to maintain the lustrous black hair prized in the Tang and Song dynasties.

Traditional use

Chinese imperial hair-and-body wash; Korean traditional scalp rinse; Japanese tea-ceremony hand cleanser.

Naturally found in

  • ●Native to central and eastern China
  • ●Cultivated in ornamental parks worldwide (thornless variety)
  • ●One of the oldest recorded plant saponins in continuous cosmetic use

Sustainability

Wild-harvested from mountain hedgerows where the tree grows without cultivation input. Our supplier belongs to a Sichuan cooperative that leaves 40% of each stand unharvested to protect regeneration.

09People often ask.

Does Gleditsia foam like shampoo?

It produces a mild, silky foam — not the aggressive lather of sulphates. That's the point: less foam means less barrier disruption.
