Product information
Sclerotium gum powder is a high-performance biopolymer derived from the fermentation of the fungus Sclerotium rolfsii. It functions as an effective thickening agent, emulsion stabilizer, and skin-conditioning ingredient. It helps build and maintain viscosity in water-based systems, stabilizes emulsions to prevent phase separation, and improves the overall skin feel of formulations. With broad pH compatibility and thermal stability, it is a versatile natural alternative to synthetic thickeners such as carbomer.

Key Characteristics
- Natural Thickener & Stabilizer: It is a highly efficient thickening and gelling agent, offering a natural alternative to synthetic polymers like carbomer. It effectively increases viscosity, stabilizes emulsions, and acts as a suspending agent.
- Excellent Rheology: It provides shear-thinning (pseudo-plastic) properties, making formulations easy to spread while maintaining a rich, creamy texture.
- Skin Conditioning: It functions as a skin conditioning agent, improving the sensory feel of products by providing a smooth, soft, and non-greasy texture.
- Environmental Sustainability: It is readily biodegradable and produced from renewable resources through a fermentation process, aligning with sustainability goals.
- Physicochemical Stability: It is highly thermo-stable, resistant to hydrolysis, and effective across a wide pH range (approx. 2.5–12).
Primary Applications
- Cosmetics & Personal Care (Primary Use): It is widely used in skincare (creams, lotions, serums, mask liquids), hair care, sunscreens, and makeup products (e.g., mascara, eyeliners). Its primary functions are to thicken, stabilize, and improve the texture and moisturizing properties of these formulations.
- Pharmaceuticals (Secondary Use): In the pharmaceutical industry, it is utilized in various dosage forms as a coating agent, stabilizer, emulsifier, and in topical formulations due to its film-forming and biocompatible properties.
- Food & Beverage (Secondary Use): In some regions, it can be used as a natural thickener and stabilizer to improve the mouthfeel and shelf life of products like sauces and dairy items.

Safety Profile
According to the Cosmetic Ingredient Review (CIR) Expert Panel, Sclerotium Gum is considered safe as used in cosmetics. Typical use concentrations in cosmetic formulations range from 0.2% to 2.0%.
Premium Upgrade: Hydrolyzed Sclerotium Gum
We also offer Hydrolyzed Sclerotium Gum, an advanced derivative of Sclerotium Gum produced through enzymatic or acid hydrolysis. This upgraded version delivers enhanced performance and superior sensory benefits for premium cosmetic formulations.
Key Advantages over Standard Sclerotium Gum:
- Cold-Processable: Unlike standard Sclerotium Gum, the hydrolyzed version can swell and hydrate in cold water, eliminating the need for heating and simplifying the manufacturing process.
- Superior Skin Feel: Provides a light, non-greasy, and non-sticky moisturizing feel with a silky, cushion-like texture. It imparts a smooth, refreshing feel without the heavy or tacky residue often associated with traditional thickeners.
- Enhanced Moisturizing & Film-Forming: Forms a thin, breathable film on the skin that attracts moisture from the air and locks it in, effectively preventing water loss and delivering long-lasting hydration. It penetrates and moisturizes the stratum corneum, improving skin transparency and radiance.
- Improved Formula Compatibility: Particularly well-suited for sheet mask serums-even at concentrations as low as 0.1%, it significantly increases the liquid-holding capacity of mask fabrics, preventing dripping and ensuring the essence stays locked in the mask.
- Multi-Functional Benefits: Functions as a humectant, skin-conditioning agent, film former, and skin protectant. It helps improve skin texture, structure, and roughness while providing soothing and moisturizing effects.
Recommended Dosage: 0.1–1.0%
Applications: Premium serums, essences, sheet mask liquids, high-end creams, and lotions where a lightweight, non-tacky feel is desired.
