Common Name(s): Sodium hydrolyzed hyaluronoyl theanine,sodium hydrolyzed hyaluronoyl theanine,theanine-conjugated hyaluronate,enhanced ha derivative

CAS Number: N/a

DESCRIPTION

What It Does: Provides ha's 1,000× water retention in a modified form designed for superior delivery or extended performance — enhanced performance versus standard sodium hyaluronate.

Why It's Used: Theanine-conjugated modification provides specific advantages over sodium ha: the specific modification providing the targeted improvement for the application

How It Works: Ha backbone (β-1,3/β-1,4 glucuronate-glcnac) provides 1,000× water binding from polyanionic carboxylates. chemical modification at c6-oh alters physicochemical properties — crosslinking increases mw and reduces rinsing; acetylation raises logp for sc penetration; silanol provides si-o sc-compatible anchoring.

Typically Found In: Anti-aging hydration,barrier support,premium serums

SCIENTIFIC NOTE

Modified ha clinical performance depends on modification degree and mw — crosspolymer hydrogels provide visible moisture-film on skin (glass-skin effect); acetylated ha provides 24h hydration persistence; standard ha provides immediate intense hydration with 2–4h duration.
