Description générale

Crystals of sodium chloride belong to the cubic crystal system. It is widely employed preservative for meat, vegetable and fish products. Its effect on the growth of salmonellae (mixed inoculum of Salmonella thompson, S. stanley and S. infantis) has been investigated in laboratory medium.

Application

Sodium chloride was used in the dissolution of polymers such as poly(allylamine hydrochloride), sodium poly(styrenesulfonate) and poly(acrylic acid).

Conditionnement

This product is also available in glass bottles.

The "layer-by-layer" (LbL) technology has been widely investigated for the coating of flat substrates and capsules with polyelectrolytes. In this study, LbL polyelectrolyte coatings applied at the surface of digitally encoded microcarriers were evaluated for the quantitative, sensitive, and simultaneous
