INGREDIENT OVERVIEW

Sodium Benzoate Powder

Sodium benzoate is a water-soluble preservative used in cosmetic formulations to support microbial stability in pH-controlled systems. It is commonly used in cleansers, toners, and emulsions where formulation pH is appropriately adjusted.

Our sodium benzoate is supplied as a high-purity, cosmetic-grade powder with a verified assay of 99.96% and low moisture content (0.24%). It is selected for consistent composition and reliable formulation performance.

In formulation, sodium benzoate is typically used as part of a broader preservation system and requires appropriate pH conditions for effectiveness.

KEY SPECIFICATIONS

Ingredient: Sodium Benzoate
INCI: Sodium Benzoate
CAS: 532-32-1
Solubility: Water soluble
Typical use level:

Starter: 0.25–0.4% in combination systems

FORMULATION NOTES

Processing notes

Add to the water phase with mixing until fully dissolved. Adjust pH as required after incorporation.

Compatibility notes

Compatible with most cosmetic ingredients
Works best in combination with potassium sorbate
Performance improves with chelating agents (e.g. EDTA)

pH notes

Effective in acidic systems (typically pH <5.5). Requires pH adjustment to function effectively.

Sensory notes

Sodium Benzoate does not significantly impact sensory profile and integrates cleanly into formulations. Sensory outcome is formulation-dependent.

Formulation examples

Cleanser system

Sodium benzoate: 0.2–0.4%
Potassium sorbate: 0.1–0.2%
Citric acid to adjust pH
Surfactant system

Supports preservation in acidic systems.

Toner system

Sodium benzoate: 0.2–0.3%
Chelating agent: as required
Humectants and Actives

Used in pH-controlled aqueous systems.

Troubleshooting

Preservation failure → check pH (must be acidic)
Microbial instability → combine with potassium sorbate
Reduced efficacy → confirm chelation and system balance

STORAGE & HANDLING

Store in a cool, dry place, protected from heat, moisture, and direct light.
Keep container tightly sealed when not in use.
Shelf life: 2 years when properly stored
