Description
Low-viscosity grade of technical-grade carboxymethyl cellulose (CMC), oriented to fluid-loss control with lower viscosity contribution.
Appearance
White or off-white fibrous powder.
Properties
Long-chain anionic cellulose ether. White/pale-yellow fibrous powder; per the manufacturer's documentation, odorless and non-toxic. Soluble in cold/hot water for transparent viscous neutral-to-slightly-alkaline solution. Stable under light and ambient temperature for long-term dry storage. For safety determinations, consult the applicable SDS.
Main Advantages
- Good chemical stability, resistant to deterioration.
- Physiologically harmless per the manufacturer's documentation for the technical grade; for safety determinations, consult the applicable SDS.
- Suspending and emulsifying stabilization.
- Good bonding and salt-resistance.
- Forms smooth, tough, transparent film.
- Stable against oil and organic solvents.
