HYDROLYZED CELLULOSE GUM.

Valuable CAS - / EMULSION STABILISING, FILM FORMING, VISCOSITY CONTROLLING

Hydrolyzed Cellulose Gum is a water-soluble polysaccharide that functions as a highly effective humectant, drawing and retaining moisture to maintain skin hydration and suppleness. Beyond its moisturizing capabilities, it also serves as a critical ingredient in formulations, enhancing texture and stability.

Science

Mechanism of Action

This ingredient operates primarily as a powerful humectant, significantly increasing the skin's capacity to hold water, thereby promoting sustained hydration. It forms a protective, non-occlusive film on the skin's surface, which effectively reduces transepidermal water loss (TEWL) and reinforces the skin's natural barrier function. Furthermore, within cosmetic formulations, it acts as a thickening, stabilizing, and emulsifying agent, optimizing product texture, viscosity, and overall performance.

Stability

Cellulose Gum exhibits reduced stability below a pH of 4.0, with an optimal pH range of 6.0 to 8.0. Elevated temperatures can temporarily decrease viscosity, though this effect is generally reversible if the heating duration is brief and the pH remains above the critical level. It demonstrates pseudoplastic, or shear-thinning, rheological behavior.

Conflicts

  • Strong oxidizing agents
  • High concentrations of salts (potential for precipitation)
  • Concentrated acid addition (can lead to polymer degradation and viscosity reduction)

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Hydrolyzed Cellulose Gum's safety for cosmetic applications. Studies on cellulose derivatives, including this ingredient, have shown minimal ocular irritation and non-to-slight dermal irritation at concentrations up to 100%. It is also noted as nonsensitizing and nonphotosensitizing. Regulatory bodies, such as the European Cosmetics Regulation, consider it generally safe for use in cosmetics, aligning with its overall practically nontoxic profile via dermal administration.
