How to use sodium dioctyl sulfosuccinate (DOSS, CAS No. 577-11-7) in textile, printing and dyeing industry

Dioctyl sodium sulfosuccinate is a kind anionic surfactant, have good wettability, permeability, emulsibility and foamability. Strong permeation ability, permeation quick and uniform as fabric rapid-permeation agent in printing and dyeing industry, can observably reduce surface tension.

Sodium dioctyl sulfosuccinate as emulsifier, detergent and penetrating agent in textile industry; DOSS as surfactant and leveling agent in printing and dyeing industry.

DOSS not able to bear strong acid, strong alkali, heavy metallic salt and reductant etc.

To treatment cotton, fibre, viscose and their blended products, can directly bleached or dyed without boiling off  

after treated fabric, can improve dyeing defects caused by dead cotton. The fabric hand feeling very soft and fullness 

after printing and dyeing. The permeability of fabric is not affect by change of temperature, acid and alkali after 

fabric processed.

Permeate effect very good under 40℃ and PH value 5-10, easy hydrolysis by alkali at hightemperatures, suit for the 

fabric first process permeating agent under 40℃ then heated.

Not resistant to strong alkali, can not direct added to concentrated alkali solution, should be diluted before adding 

the alkali solution.

If the bubble is much during usage, can add a little defoamer, such as octanol, tributy phosphate.

The sizing agent should be first depleted when green body is refining and bleaching, to ensure permeate effect.

Sodium dodecylbenzene sulfonate (SDBS) application, prospect and production

Image
Sodium dodecylbenzene sulfonate (SDBS) is an anionic surfactant widely used in household detergents, industrial cleaners, and personal care products. It appears as a white to light yellow powder or paste and is known for its excellent emulsifying, foaming, and cleaning properties. Chemically, it is the sodium salt of dodecyl benzene sulfonic acid and is synthesized through the sulfonation of linear alkyl benzene followed by neutralization with sodium hydroxide. Its strong surfactant activity makes it a key ingredient in many formulations. We, Henan Surface Chemical Industry Co., Ltd ( https:// www.surfaceindustry.com ) can manufacture full range sodium dodecyl benzene sulphonate (SDBS), in addition to liquids, pastes, and powders, there are also high-purity product, high-purity SDBS 90% even 95% can be used for laboratory biochemical analysis, electrophoresis, and ion reagents, as an antistatic agent. We have four sets of advanced high-tower spraying powder drying production lines...

Use of Sulfonate Salts in Concrete

Image
Sulfonate Salts ( sodium dodecyl benzenesulfonate , sodium linear alkyl benzene sulfonate and sodium alpha olefinsulfonate ) mainly act as air entraining agents and water reducing agents in concrete. 1. Major function: 1). During the mixing process of concrete, a large number of uniformly distributed, stable and closed tiny bubbles are generated inside the concrete. 2). Improve concrete cohesion, water retention and anti-segregation properties 3). Improve concrete pumpability 4). Reduce plastic cracks and settlement cracks 5). Greatly improve concrete's ability to resist freeze-thaw cycles 6). Enhance concrete's resistance to chemical attack 2. Dosage: The appropriate dosage is 0.005-0.015% of the general cement mass 3. Application: 1). Can be used for frost-resistant concrete, impermeable concrete, sulfate-resistant concrete, severely water-infiltrated concrete, lean concrete, lightweight aggregate concrete, artificial aggregates made with ordinary concr...
