MICCEL – CMC
Microcrystalline Cellulose & Carboxymethyl Cellulose Sodium IP/USP
Solution for Suspensions, Lotions and Creams
- Suspension: As suspending agent for readily constitutable suspension Absence of sedimentation in some of formulation.
- Lotion: As oil/water emulsifier for lotions and creams
- Creams: Emulsion Stabilizer and thickener with opacifier for creams and gels.
MICCEL CMC is the mixture of microcrystalline cellulose and carboxymethyl cellulose Sodium various ratio depend on application. We produce following types of grades
Specification
| Sr. no. | Test | Specification |
| 1 | Description | Tasteless, odoriess, white, coarse to fine powder. |
| Solubility | Swells in water, producing, when dispersed, a white, opaque dis or gel Insoluble in organic solvents and in dilute acids. | |
| 2 | Identification | |
| Test-A | A white opaque, dispersion is produced that does not settle on Standing. | |
| Test-B | Each drop forms a white, opaque globule that does not disperse standing | |
| Test-C | No blue or purplish blue color produced. | |
