Sodium carboxymethylcellulose Application in Non-Phosphorus Detergents and Soap-Making Industry
Sodium carboxymethylcellulose was found to have an effect on improving washing performance in 1935. Since then, Sodium carboxymethylcellulose has been used as an excellent anti re-deposition agent and it has had nearly a half-century history. As a detergent builder, detergent cmc mainly plays a role in preventing dirt from re-deposition.
For one thing, it can prevent the deposition of organic salts of heavy metals. For another thing, the dirt suspension which has entered into the aqueous solution because of washing will disperse in the aqueous solution, so it can effectively prevent dirt from depositing on the fabrics.
Consequently, if washing powder and soap with Sodium carboxymethylcellulose are used to do some washing, the cleansing power can be enhanced; washing time can be shortened; white fabrics can keep the whiteness and cleanliness while colored fabrics can maintain the original color brightness. It works best especially washing cotton fabric in hard water because the fabric after washing has a soft feeling and is more comfortable to wear.
In making soap, the function of adding Sodium carboxymethylcellulose is the same as that in washing powder. Moreover, it enables the pressed soap pliable and flexible, more smooth, beautiful and durable.
