Biological Properties

Safety, Stability & Biodegradability

Overview

Carboxymethyl Cellulose possesses excellent biological properties that make it suitable for sensitive applications in food, pharmaceuticals, and personal care. Its non-toxic nature, combined with good storage stability and biodegradability, contributes to its widespread acceptance across industries with strict safety requirements.

Microbial Degradation

CMC shows resistance to microbial attack under normal storage conditions, contributing to its long shelf life.

  • Resistant to most bacteria and fungi
  • Dry powder stable for years
  • Biodegradable in environment

Storage Stability

Properly stored CMC maintains its properties over extended periods, ensuring consistent performance.

  • Powder stable 2+ years when dry
  • Store in cool, dry conditions
  • Solutions stable for weeks to months

Toxicological Safety

CMC is recognized as safe for use in food, pharmaceutical, and personal care products.

  • FDA GRAS approved
  • Non-toxic and non-irritating
