Manufacturing of AEROSOL OT-75:

AEROSOL OT-75 is manufactured through the controlled synthesis of a sulfosuccinate surfactant, typically sodium dioctyl sulfosuccinate, followed by formulation to a liquid product containing approximately 75% active matter.

The process begins with the esterification of suitable branched alcohols to form dioctyl sulfosuccinate, which is then sulfonated and neutralized with a sodium base to produce the anionic surfactant.

The resulting product is carefully diluted and homogenized with water or a compatible carrier to achieve the desired active concentration, viscosity, and handling characteristics.

Manufacturing operations emphasize strict control of reaction conditions, pH, and purity to ensure consistent surfactant performance.

Final production steps include filtration, quality control testing, and packaging in appropriate containers for industrial and formulation use.

Synthesis of AEROSOL OT-75:

This intermediate is then sulfonated, introducing the sulfonate group onto the succinate backbone, followed by neutralization with a sodium base to yield the sodium salt.

The crude surfactant is subsequently adjusted, diluted, and homogenized to achieve a liquid formulation containing approximately 75% active matter.

Careful control of reaction temperature, pH, and neutralization ensures high purity, consistent molecular structure, and optimal wetting and dispersing performance in the final AEROSOL OT-75 product.
