CMC Carboxhymethyl cellulose

Description of CMC carboxymethyl cellulose 

CMC carboxymethyl cellulose is a type of cellulose derivative that is commonly used in a variety of industrial and commercial applications. It is a water-soluble polymer that is derived from cellulose, which is a natural polymer found in plant cell walls.

CMC is commonly used as a thickener, stabilizer, and binder in food products such as ice cream, salad dressings, and baked goods. It is also used in pharmaceuticals, cosmetics, and personal care products as a thickening agent and emulsifier.

CMC is often preferred over other thickeners because it is stable across a wide range of temperatures, pH levels, and ionic strengths. It is also relatively inexpensive and has a long shelf life.

However, CMC can also have negative environmental impacts, especially when it is not disposed of properly. It is not biodegradable, and can contribute to the accumulation of microplastics in waterways and oceans. As such, it is important to use and dispose of CMC responsibly.

CMC Carboxymethyl Cellulose for Drilling

CMC Carboxymethyl Cellulose is favored for its viscosifying power and additionally for its utility as a water loss preventive is in drilling muds to be used in well drilling. The optimum product for drilling muds and for many uses may be a product having a high degree of its substitution in order that it’s extremely soluble and having a high relative molecular mass so that it produces a high viscosity answer once dissolved in composition.

When used as a thickener in fresh water systems, the high relative molecular mass product performs well, however once the meant application needs the utilization of salt composition, as often happens, notably within the case of muds, they are doing not perform well in the least.

There’s a marked decrease in solubility and answer quality of high relative molecular mass in salt composition as compared to water, leading to only partial dissolution of the chemical compound and cloudy, structured solutions of low viscosity.

CMC Carboxymethyl Cellulose Applications

One of the applications within which CMC carboxymethyl Cellulose finds wide usage is as a stuff in lubricating substance to be used in well drilling. Such muds are often ready at the drilling wherever fresh water might not continuously be offered. In such cases solubility in salt solutions will be important and also the method of this invention makes salt soluble CMC carboxymethyl cellulose.

Surprisingly, and erratically, it is ready in keeping with the strategy of the invention also exhibits a second improved property useful to muds; particularly, it well decreases the loss potential of such a mud.

Water loss is outlined because the loss of liquid from a lubricating substance to the well formation. The bigger the water loss worth of a mud, the bigger is that the potential of losing water from the mud to the formation throughout for this industry.
