Extraction & Purification Excellence
Macromolecular Preservation
Tremella's film-forming hydration depends entirely on maintaining its high molecular weight. High-shear forces or excessive heat during manufacturing cleaves these delicate polymers. Tihealth utilizes gentle, low-temperature enzymatic hydrolysis and gradient extraction, preserving the 1M+ Dalton chain lengths critical for cosmetic viscosity.
Membrane Ultra-Filtration (Clarity)
Crude extracts contain insoluble fibers and proteins that turn liquids cloudy and brown. We pass the extract through successive cross-flow membrane ultra-filtration stages. This strips away cellular debris, yielding a purified extract that dissolves into a brilliant, translucent gel without causing turbidity in your final serum.
Ethanol Precipitation Purity
To ensure the ≥85% active specification isn't padded with cheap maltodextrin carriers, we employ targeted ethanol precipitation. This step selectively crashes out the pure, active Tremella heteropolysaccharides while leaving inactive monosaccharides behind, ensuring clinical-grade efficacy.
Mechanism of Action (Cosmetic & Nutritional)
Unparalleled Hydration & TEWL Reduction
Tremella polysaccharides contain abundant hydroxyl and carboxyl groups (glucuronic acid) that actively bind water molecules. When applied topically, it forms a highly breathable, elastic hydration network over the stratum corneum, significantly reducing Trans-Epidermal Water Loss (TEWL) and drawing moisture deep into the epidermis.
Antioxidant & Photoaging Defense
Beyond hydration, the polymer matrix exhibits profound free-radical scavenging capabilities. By neutralizing Reactive Oxygen Species (ROS) induced by UV exposure and environmental pollution, it actively prevents the oxidative degradation of dermal collagen and elastin, serving as a primary anti-aging active.
Rheological Modifier (Silky Skin-Feel)
Unlike high-molecular-weight hyaluronic acid, which can leave a sticky or tacky residue, Tremella provides a luxurious, silky slip on the skin. It acts as a natural rheological modifier, enhancing the viscosity and tactile sensory profile of cosmetic emulsions without compromising spreadability.
Commercial Formulation Applications
Premium Hydration Serums
The core vegan alternative to Sodium Hyaluronate. Perfectly suited for clear, intensive hydration serums, barrier-repair lotions, and anti-aging eye creams.
Nutricosmetics (Beauty from Within)
Utilized extensively in functional dietary supplements, collagen-boosting liquid shots, and wellness gummies targeting dermal hydration from the inside out.
Face Masks & Hydrogels
Because it forms a stable, viscoelastic colloid, it is the premier humectant base for sheet mask essences, providing immediate plumping effects.
Clean-Label Haircare
Acts as a natural, silicone-free smoothing agent in shampoos and conditioners, reducing friction and protecting the hair cuticle from dehydration.

Formulator & Procurement FAQ
Q1: How does Tremella Extract compare to Sodium Hyaluronate in cosmetics?
Tremella polysaccharide is a 100% natural, plant-based alternative. Its molecular particles are actually smaller than traditional high-molecular-weight hyaluronic acid, allowing it to penetrate the skin more easily while still holding massive amounts of water. Crucially, it provides a much silkier, non-tacky finish compared to the "sticky" feel often associated with high concentrations of HA.
Q2: Why does Xi'an Tihealth verify the polysaccharide assay via Phenol-Sulfuric Acid instead of generic UV?
To prevent false positives caused by cheap dextrin or starch fillers (adulteration). Our QA lab utilizes the verified Phenol-Sulfuric Acid method calibrated against a specific D-glucose standard curve, coupled with internal Glucuronic Acid verification via carbazole assay. This ensures you are purchasing genuine, highly active film-forming heteropolysaccharides.
Q3: Will the powder dissolve clearly in water without clumps?
Yes. However, because it is a high-molecular-weight hydrocolloid, it requires proper dispersion. It must be added slowly to water under constant mechanical stirring to prevent "fish-eye" clumping. Once hydrated, it forms a perfectly clear, translucent, and stable viscous gel.
Q4: What are the storage requirements to prevent degradation?
Due to the presence of highly hydrophilic hydroxyl groups, this powder is incredibly hygroscopic (it will absorb moisture from the air). It must be stored in its original, unopened commercial packaging (standard 25kg fiber drums with double-layer PE moisture barrier bags) in a cool, dry environment below 25°C.
