Products Description
Scleroglucan Powder, also known as Sclerotium Gum, is a natural biopolymer produced via aerobic fermentation of sugar raw materials by Sclerotium rolfsii fungus. It forms a stable triple helix spatial structure in aqueous solution, endowing it with unique rheological properties, temperature resistance and electrolyte tolerance.
Mechanistically, its long-chain polysaccharide structure achieves three core functional effects:
- Thickening & Gelation: The molecular chain intertwines in water to form a network structure, rapidly increasing system viscosity and forming smooth transparent gels without syneresis.
- Emulsion Stabilization: It adsorbs on the oil-water interface to form a protective film, inhibiting droplet aggregation and layering, compatible with anionic, nonionic and amphoteric surfactants.
- Film-forming & Skin Conditioning: It forms a breathable flexible protective film on the skin surface, reducing transepidermal water loss (TEWL), locking moisture and soothing external irritation.
The product maintains structural stability in an ultra-wide pH range of 2.5–12.0 and withstands high temperature up to 130°C. It is readily biodegradable, non-bioaccumulative, and conforms to clean beauty and natural cosmetic formulation standards.

Applications & Clear Restrictions
Main Applications & Recommended Dosage
- Facial Care Essence & Lotion: Dosage 0.2–1.5%, used as thickener and moisturizing film-former, suitable for sensitive skin formulas.
- Transparent Mask & Hydrogel: Dosage 1.0–3.0%, forms high-transparency stable gel, improves skin smoothness.
- Sunscreen & After-sun Products: Dosage 0.3–1.2%, stabilizes sunscreen system, reduces chemical sunscreen irritation and enhances water resistance.
- Gentle Cleansers & Baby Care: Dosage 0.1–0.8%, cooperates with surfactants to improve mildness and stabilize foam.
- Hair Care Products: Dosage 0.2–1.0%, thickens shampoo, conditions hair and improves combability.
- Color Cosmetics: Dosage 0.5–2.0%, stabilizes pigment suspension and prevents precipitation and delamination.
Clear Usage Restrictions
- Not suitable for high-concentration strong oxidant formulas, easy to cause molecular chain degradation and viscosity attenuation.
- Avoid direct compounding with high-concentration cationic polymers exceeding 5%, risk of flocculation and precipitation.
- Not recommended for formulas with long-term storage at temperature above 85°C, easy to cause irreversible viscosity loss.
- Not applicable to industrial high-viscosity heavy-duty thickening scenarios, limited by molecular chain structural characteristics.
Safety Profile
- Acute Toxicity: Rat oral LD50 >5000 mg/kg, classified as non-toxic grade.
- Skin Irritation: Rabbit skin irritation test shows minimal irritation score <0.3/4.0; human cumulative irritation test non-irritating.
- Eye Irritation: In vitro EpiOcular model test causes no corneal damage; 3% concentration leads to zero stinging and redness in human eye tests.
- Genotoxicity: Ames test, in vitro chromosome aberration test and in vivo micronucleus test all show negative, no genotoxic risk.
- Sensitization: Human patch test with 120 volunteers shows no allergic reaction, non-sensitizing.
