Sclerotium Gum

What is Sclerotium Gum?

Sclerotium Gum is a branched, high-molecular-weight polysaccharide obtained through the aerobic fermentation of carbohydrates by the fungus Sclerotium rolfsii. This eco-friendly biotechnological process produces a renewable, plant-based gelling agent widely incorporated into cosmetics like moisturizers, serums, cleansers, and sunscreens. In formulations, it rapidly hydrates to create a clear, thermoreversible gel network that imparts high viscosity at low usage levels, typically under 1%. This structure excels in suspending particles, boosting emulsion integrity by reinforcing droplet interfaces, and delivering a silky, non-tacky sensory profile. Its shear-thinning properties ensure easy spreading, while broad pH stability and compatibility with electrolytes and surfactants make it versatile for clear gels and high-water systems, supporting natural and sustainable product development.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.

Benefits

Enhances formulation stability to keep ingredients well-mixed.

Improves product texture for smoother application and skin feel.

Supports skin softness through gentle conditioning properties.

Who It's For
