Three Aspects Must Be noticed When Casson Preservatives Are Used,

 

The application of preservatives for cassava is becoming more and more widespread. Especially in industry, cassava preservatives are used in paints and paper printing and dyeing plants because they can inhibit the growth of bacteria and can kill bacteria quickly. It plays a very good role in protecting paints and paints.


Casson has good performance and strong stability, but there are also some things to note when using it:


        1. Preservatives from Casson should be kept in direct contact with the eyes. Once in contact, they should be rinsed with plenty of water immediately, and do not contact the skin for prolonged periods of time. This also reminds us that we should wear protective measures when using.

 

        2. Preservatives from Casson must not come into contact with reducing metals during the storage process, such as metal iron or aluminum, so as not to cause decomposition of the product.


        3. Casson preservatives have poor stability in alkaline media with pH > 9.0 and should not be used. When nucleophilic chemicals are compatible with CASON preservatives, such as S2- and R-NH2, the quality of the product will be reduced or even completely defeated.


        Therefore, when using CASON preservatives, it is necessary to take protective measures. As well as during storage, it is necessary to understand what are the taboos to avoid adverse reactions during use.
