Sodium dodecylbenzenesulphonate #CAS25155-30-0
Sodium dodecyl benzene sulfonate (SDBS) is an anionic surfactant. It is easily soluble in water to form a stable aqueous solution with good foaming and wetting properties. It has remarkable surface activity and excellent emulsifying, dispersing and decontaminating abilities. It shows stable performance under neutral and weakly alkaline conditions. It will decompose and lose its surface activity when exposed to strong acid for a long time. It has good compatibility with non-ionic surfactants and other detergent additives. It is not volatile, and will gradually lose its foaming and cleaning effect under high temperature for a long period. It can react with strong oxidants and may produce adverse changes. It is slightly hygroscopic and should be stored away from moisture.
Applicaion of Sodium dodecylbenzenesulphonate
Sodium dodecylbenzenesulfonate has been used to stabilize dispersions of graphene nanoflakes (GNFs) during the preparation of the liquid phase of GNFs. It can also suspend single-walled carbon nanotubes as individuals in aqueous media and also give well-resolved spectral features.
These frothers are mixtures of alcohols containing 6–8 carbon atoms. They were at one time marketed by DuPont and they are tailored frothers for specific ore types. The bestknown frother from this group is methyl isobutyl carbinol (MIBC) and 2-ethyl hexanol.Aliphatic alcohol frothers are used as mixtures of different carbon lengths and as a mixture of hydrocarbon oils.
Sodium dodecylbenzenesulfonate (SDBS) is a widely used anionic surfactant. It possesses excellent wetting, emulsifying, dispersing, foaming and detergency properties. It is mainly applied in the production of household detergents such as laundry powder, liquid detergent and dishwashing cleaner. It can also serve as the core raw material for industrial cleaning agents used to remove oil stains and dirt on metal surfaces, textile fabrics and equipment. In textile industry, it acts as a scouring agent and dyeing auxiliary, helping to remove grease and impurities from raw fibers and improving the uniformity of dye uptake. It works as an emulsifier and dispersant in pesticide formulations, stabilizing pesticide emulsion and preventing active ingredient sedimentation. It can be used as an emulsifying auxiliary for emulsion polymerization in plastic and rubber industries. It is compatible with many non-ionic surfactants and inorganic builders under neutral and weakly alkaline conditions. It can maintain stable surface activity in low to medium temperature environments. It is suitable for compounding with different additives to meet the diversified demands of daily cleaning, industrial decontamination, textile pretreatment and pesticide processing.
