Sodium Diethylhexyl Sulfosuccinate(DOSS / AOT)CAS 1639‑66‑3

Physicochemical properties

Application Areas

Dyeing and printing industry: It is used in the mercerizing process of cotton fabrics, which can accelerate the penetration of concentrated alkali solution into the fibers and shorten the treatment time to 30~50 seconds. The treated fabrics can be directly bleached or dyed without scouring.
Leather processing: As a soaking aid, it enhances the softness and permeability of leather.
Pesticide emulsification: Enhances the spreadability and permeability of pesticides, thereby improving their efficacy.
Other fields: It can also be used in detergents, degreasing agents, refining agents, and chemical intermediates.

Storage conditions

Store in a dry and ventilated warehouse, sealed, and avoid high temperatures and direct sunlight. The shelf life of some products ranges from 12 months to 2 years (specifically as stated in the product instructions)

‌‌Safety precautions

Usage restrictions:
Rapid penetrant T is not resistant to strong alkali and should not be added directly to concentrated alkali solution. It should be added after the alkali solution has been diluted.
It is an anionic surfactant and cannot be used in the same bath with cationic surfactants and cationic dyes.
During the refining and bleaching process of the raw material, it is recommended to first thoroughly remove any impurities from the slurry to ensure optimal penetration effect.
Defoaming treatment:
If excessive foam is observed during use, a small amount of defoaming agent such as octanol or tributyl phosphate can be added to eliminate the foam.
Temperature control:
Rapid penetrant T has a better penetration effect at temperatures below 40℃. It is prone to hydrolysis when exposed to alkali at high temperatures. Therefore, it is advisable to treat the fabric with penetrant T at temperatures below 40℃ before raising the temperature.
