The highly active surfactant more commonly known as sodium docusate or dioctylsulfosuccinate is an anionic surfactant which is used for the formation of micro-emulsions without the use of secondary and additional surfactants and exhibits a wide range of aqueous phase behaviors, including multiple liquid crystal phases.
In the food industry, sodium docusate is used as a surfactant, wetting agent, dispersant, thickener, solvent, emulsifier. Concentrations up to 0,5% are used. It is commonly found in spreadable fat blends, spreadable cheeses, cottage cheese spreads, salad dressings and is designated E480 in the E classification.
In animal husbandry, DOSS is used as one of the components in microencapsulation. This method is used to protect the valuable components of feed additives from degradation in the stomach and to allow them to travel further down the digestive tract.
In medicine, sodium docusate is used as an active ingredient to remove sulfur from the ears, to treat peristalsis, anal lesions and other haemorrhagic lesions, and as a lubricant and emulsifier in the manufacture of tablets or active emulsions.
In agriculture, DOSS is used as an emulsifier in the manufacture of fungicides, herbicides and other products to facilitate mixing with water and spray application on leaves.
In cosmetics, dioctyl sulphosuccinate is used both as an emulsifier in O/W emulsion-based products and as a cleanser in water-based products such as surfactant. It can be used as a hydrotrope to produce transparent formulations when they are otherwise opaque due to emulsion formation. It is commonly found in bath products, body and skin products, shaving foams, etc. In cosmetic products, the following functions are distinguished:
- Cleanser: helps keep surfaces clean
- Emulsifier: Promotes the formation of intimate mixtures between immiscible liquids by modifying surface tension (water and oil)
- Hydrotrope: Increases the solubility of a low soluble substance in water.
- Surfactant: reduces the surface tension of the cosmetic and contributes to the even distribution of the product during application
