Disodium lauryl sulfosuccinate belongs to the group of compounds that are called SLS but is less irritating than them.
Disodium lauryl sulfosuccinate is produced synthetically, but components may be obtained from plants.
Origin of Disodium Lauryl Sulfosuccinate:
Disodium lauryl sulfosuccinate is obtained via an esterification and sulfonation reaction.
In the esterification reaction, lauryl alcohol and maleic anhydride react to form lauryl maleate.
In the sulfonation reaction, lauryl maleate reacts with sodium bisulfite to produce the byproduct, Disodium lauryl sulfosuccinate.
Production of Disodium Lauryl Sulfosuccinate:
The production of Disodium lauryl sulfosuccinate involves a chemical synthesis process that combines fatty alcohols (typically derived from plant oils like coconut or palm oil) with sulfosuccinic acid derivatives.
Here is an outline of the production process:
Raw Material Preparation:
Lauryl Alcohol (dodecanol or C12 alcohol):
This is the key fatty alcohol, typically derived from coconut or palm oil through a process of fatty acid reduction.
Maleic Anhydride:
A chemical compound used as a precursor for sulfosuccinic acid.
Sodium Bisulfite:
Provides the sulfonation component in the reaction.
Esterification:
The process starts with the reaction between maleic anhydride and lauryl alcohol, resulting in a half-ester known as lauryl maleate.
This step attaches the lauryl (C12) group to the maleic anhydride.
The esterification typically occurs at elevated temperatures in the presence of a catalyst to speed up the reaction.
The reaction must be carefully controlled to ensure proper conversion and yield.
Sulfonation:
After the esterification, sodium bisulfite is added to the reaction mixture, which leads to the sulfonation of the maleate ester.
This results in the formation of sulfosuccinate, creating the sulfonic acid functional group necessary for surfactant activity.
Neutralization:
The resulting sulfosuccinic acid derivative is neutralized using sodium hydroxide (NaOH) to form disodium salts, producing Disodium lauryl sulfosuccinate.
This neutralization process adjusts the pH of the solution and finalizes the salt form of the surfactant.
Purification and Drying:
After the reaction is complete, the mixture is typically purified through filtration to remove any unreacted materials or by-products.
Disodium lauryl sulfosuccinate is then dried to produce a powder or granule form, depending on the desired end product.
In some cases, water or solvent-based extractions are used to remove impurities and ensure high-quality surfactant production.
Final Product:
The final product, Disodium lauryl sulfosuccinate, is a white to off-white powder or granule with mild surfactant properties.
Disodium lauryl sulfosuccinate is typically packaged for use in personal care, household cleaning, or industrial products.
Disodium lauryl sulfosuccinate may undergo additional quality checks to ensure it meets specifications for purity, pH, active surfactant content, and low levels of residual substances such as free fatty alcohols or sodium chloride.
Environmental Considerations:
The production process for Disodium lauryl sulfosuccinate is generally considered environmentally friendly, especially when plant-based lauryl alcohol is used.
Additionally, the surfactant is biodegradable, which further contributes to Disodium lauryl sulfosuccinate's eco-friendly profile.
However, sustainable sourcing of raw materials like coconut or palm oil is critical to reduce the environmental impact associated with the production chain.
