General Description:

Sodium Alginate is a natural, water-soluble polysaccharide derived from the cell walls of brown seaweed (Phaeophyceae). It is the sodium salt of alginic acid, known for its gel-forming, thickening, and stabilizing properties. It is widely used across industries due to its biocompatibility, non-toxicity, and natural origin, making it an ideal choice for clean beauty and eco-conscious formulations.

Film-forming Agent: Provides a lightweight film that helps lock in moisture.

Emulsion Stabilizer: Prevents separation in oil-in-water emulsions.

Moisturizing Agent: Enhances hydration by forming a breathable, protective barrier on the skin.

Exfoliating Gels & Peel-off Masks: Its gelling property is key in forming smooth, peelable masks.

Common Applications:

  • Face masks (especially peel-off)
  • Lotions and creams
  • Toothpastes
  • Hair styling gels
  • Soothing gels
  • Cleansing systems (shower gels, scrubs)

Hazard / Safety Considerations:

Safety Profile: Sodium Alginate is non-toxic, non-irritating, and biodegradable. It is considered safe for use in both leave-on and rinse-off products.

Allergenicity: Rarely associated with allergic reactions or skin sensitivity.

Inhalation Risk: In powdered form, may cause mild mechanical irritation if inhaled during handling. Recommended to handle in a well-ventilated area with PPE (for manufacturers).

Environmental Impact: Eco-friendly, renewable, and biodegradable. Common in natural and organic-certified formulations.

Regulatory Status: Approved for use in cosmetics by major global regulations including EU, FDA, and EWG.
