Please rest assured to wholesale bulk tremella polysaccharide powder for sale here from our factory. Customized orders are welcome.

Tremella polysaccharide comes from the fruiting body of Tremella fuciformis, known as silver ear or snow fungus. This mushroom has a long history in China as both a food and a tonic. The polysaccharide fraction is the main bioactive component, and it has become a staple in skincare and supplement formulations.

The molecular structure of Tremella polysaccharide is an acidic heteropolysaccharide with a mannan backbone. Mannose makes up 45–77% of the sugar composition, with glucuronic acid, xylose, and fucose as significant secondary components . This structure gives the polysaccharide a strong water-binding capacity.

Our Tremella Polysaccharide Powder is a water-extracted, purified ingredient. We use hot water extraction followed by ethanol precipitation and drying, the standard method for producing cosmetic-grade material . The result is a fine powder that dissolves in water and forms a slightly viscous, clear solution.

We produce Tremella Polysaccharide Powder with a focus on purity and batch consistency. The extraction process matters here. The 2024 standards for cosmetic-grade Tremella polysaccharide specify total sugar content ≥ 90%, glucuronic acid ≥ 18%, and protein ≤ 0.1% . These are the numbers we target for every batch.

We test total sugar by the phenol-sulfuric acid method and verify monosaccharide composition by HPLC. Glucuronic acid content is a key indicator-it reflects the acidic polysaccharide structure that drives the moisturizing performance. We also screen heavy metals, microbiology, and clarity of the water solution.

• Superior Moisture Retention

Tremella Polysaccharide Powder holds water exceptionally well. Published data shows that 1 gram of the powder absorbs 150–200 milliliters of water with no free water separation . Topical application increases skin stratum corneum hydration by 35–56% on normal skin and 20–44% on dry skin . This makes it a strong candidate as a hyaluronic acid alternative.

• Film-Forming and Skin Feel

The polysaccharide forms a transparent, breathable film on the skin. This film increases skin gloss, makes wrinkles appear less visible, and provides a dust-resistant effect . The slip is smooth without being tacky, which formulators appreciate in serum and essence formats.

• Antioxidant and Anti-Photoaging Activity

Research on UV-induced photoaging shows Tremella polysaccharides reduce skin water loss, ameliorate structural alterations, and increase collagen type I content . The protective effect is linked to antioxidant enzyme activity that inhibits lipid peroxidation.

• Skin Barrier Support

Tremella Polysaccharide Powder supports barrier function by increasing filaggrin and loricrin expression, two proteins critical for epidermal differentiation and barrier formation . This translates to reduced transepidermal water loss and improved skin resilience.

• Whitening and Melanin Inhibition

Recent research demonstrates that oxidized Tremella polysaccharide inhibits melanin production through the α-MSH/cAMP/MITF/TRP1/DCT/TYR pathway . This multi-pathway regulation offers a gentler approach to skin brightening compared to single-target agents.

Skincare Serums and Essences

Tremella Polysaccharide Powder is the workhorse of hydrating serums. It dissolves clear, forms a light film, and delivers moisture without a heavy feel. Formulators use it as a partial or full replacement for hyaluronic acid.

Moisturizers and Creams

The polysaccharide adds slip and moisture-binding capacity to emulsions. It helps reduce transepidermal water loss and supports barrier function over time.

Sunscreen and After-Sun Products
The anti-photoaging and antioxidant properties make it suitable for UV protection formulas. Research shows it reduces skin water loss and protects against structural damage from UV exposure.

Sheet Masks and Hydrogels
The film-forming property works well in sheet mask essences and hydrogel patches. It holds moisture against the skin and provides a smooth, non-tacky finish.

Dietary Supplements
Tremella polysaccharide capsules and powder blends are used for immune support and skin health from within. Human studies on oral Tremella have shown improvements in memory complaints and metabolic markers.

Q: Is Tremella Polysaccharide the same as hyaluronic acid?
A: No. They are different molecules. Tremella polysaccharide is an acidic heteropolysaccharide from mushroom. Hyaluronic acid is a glycosaminoglycan found in connective tissue. Both hold water, but Tremella has a different structure and film-forming behavior.

Q: How does it compare to hyaluronic acid in moisture retention?
A: Published data shows Tremella polysaccharide holds 150–200 times its weight in water . This is comparable to or exceeds typical HA water-binding capacity. Formulators often use it as a plant-derived alternative.

Q: What is the recommended usage level?
A: In skincare formulas, typical use ranges from 0.1% to 2% depending on the desired viscosity and moisturizing effect. For serums, 0.5% to 1% is common. Contact us for specific recommendations.

Q: Does it dissolve clearly in water?
A: Yes. High-purity Tremella Polysaccharide Powder dissolves in water to form a clear, slightly viscous solution. Transmittance at 660nm is ≥ 99% for our standard grade.

Q: Is it safe for sensitive skin?
A: Tremella polysaccharide has a long history of food use in China. Cosmetic-grade material shows no cytotoxicity and zero primary irritation index in testing . It suits sensitive skin formulations.

Q: Can you provide samples?
A: Yes. We send 10–100g samples with a Certificate of Analysis. The sample is free; you cover shipping.
