| Message: | Under conditions of different concentrations, temperatures, and pH values, Their viscosity changes and rheological changes are different, and their ion resistance and shear resistance are also different. . The conventional viscosity of Carbomer 980 is 40,000-80,000, and the conventional viscosity of Carbomer 940 is 50,000-650000. In contrast, the conventional viscosity of Carbomer 980 is higher.
Secondly, carbomer 940 has better permeability than 980, but if you need to prepare 75% leave-in gel, you need to use carbomer
980, because carbomer 940 can only be applied to a concentration below 65%, the gel will become white if it exceeds this concentration and directly affect the appearance.
But 980 has higher ion resistance than 940, so 980 can provide relatively higher viscosity and yield value when the ions increase.
The last thing to say is the difference in application. Carbomer 980 has slight elasticity and skin
It feels moisturizing and smooth, suitable for medium or thick-feeling formulas, and it is not sticky after use; Carbomer 940 has a clearer skin feel and is suitable for refreshing formulas, so we cannot generalize which of the two is better. , But should choose the right product according to the specific application direction.
So if you want to answer the question of which carbomer 980 or 940 is better, you can’t just rely on a single factor. |
