Introdução ao produto

Carboxymethyl cellulose (CMC), also known as cellulose gum, is a cellulose derivative with carboxymethyl groups attached to some of the hydroxyl groups of its glucopyranose monomers. Essentially, it’s a modified form of cellulose that becomes water-soluble. It’s often used in its sodium salt form, called sodium carboxymethyl cellulose.

Uses

In the food industry, CMC is a popular food additive used to enhance texture, stability, and shelf life. Its primary functions include:

  • Thickening and Stabilizing Agent: Increases viscosity and prevents ingredient separation.
  • Water Retention Agent: Helps maintain moisture, improving freshness and extending shelf life.
  • Emulsifier: Assists in blending immiscible ingredients like oil and water, ensuring a smooth, consistent product.
  • Anti-Crystallization Agent: Prevents large ice crystal formation in frozen desserts, leading to a smoother texture.
  • Dough Improver: Enhances dough texture, elasticity, and water-holding capacity, particularly in gluten-free baking.

In the cosmetics and personal care industry, CMC is a key ingredient that enhances product texture, stability, and performance.
