Sodium Lignosulfonate

1. Definition Sodium Lignosulfonate:

Sodium Lignosulfonate is a water-soluble lignin derivative that is commonly used in cosmetics as a dispersing agent, emulsifier, and stabilizer. It is derived from wood pulp and is known for its natural and environmentally friendly properties.

2. Use:

Sodium Lignosulfonate is used in cosmetics to improve the texture and consistency of products. It helps to disperse pigments evenly in formulations, preventing clumping and ensuring a smooth application. It also acts as an emulsifier, helping to blend oil and water-based ingredients together, and as a stabilizer, prolonging the shelf life of products.

3. Usage Sodium Lignosulfonate:

When using Sodium Lignosulfonate in cosmetics, it is important to follow the recommended guidelines provided by the manufacturer. It is typically used in small concentrations, usually around 0.1-1% of the total formulation. Overuse of Sodium Lignosulfonate can lead to product instability and may affect the performance of the cosmetic product.

Precautions: While Sodium Lignosulfonate is generally considered safe for use in cosmetics, some individuals may be sensitive to this ingredient. It is recommended to perform a patch test before using products containing Sodium Lignosulfonate, especially if you have sensitive skin. If any irritation occurs, discontinue use immediately.
