a. wealthy toothpaste grade cmc features
1.good rheological property and thixotropic property.
2. acid resistance: ph 2-4.
3.salt resistance: the addition of salt will not decrease but rather increases the viscosity of cmc aqueous solution
4.thermal resistance.
5. high transparency.
6 .antibacterial.
b. cmc’s function in toothpaste
1. good compatibility, can be mixed with various ingredients of toothpaste .
2 .good thickening effect, helps retain extrusion set.
3. fine and glossy of toothpaste, no dehydration, no de-cladding .
4. good stability, suitable thickness; can offer toothpaste special comfortable mouthfeel and gloss.
toothpast grade cmc:th9、th10、th12、t500, special grade could be developed according to customer’s request.
application:
as a thickening agent, cmc is widely used in toothpaste, and mainly takes effects of excipients and bonding. cmc can make toothpastes have a certain consistency, keep pastes into strips, and have good skeleton to prevent collapse and thinning out of toothpastes, so that can make the pastes keep delicate and smooth.
