Sodium c10-13 alkyl benzenesulfonate is a chemical compound used in many applications from cosmetics to construction.
The name describes the structure of the molecule:
- Sodium indicates the presence of a sodium ion, which gives the compound water-soluble properties and makes it suitable as a surfactant in many products.
- C10-13 Alkyl refers to the alkyl chain of varying length between 10 and 13 carbon atoms. This alkyl chain can vary in length, which can influence the surfactant's properties.
- benzenesulfonate indicates the presence of a benzene sulfonate group, which gives the compound detergent and foaming properties.
Raw materials used in production:
Sodium C10-13 alkyl benzene sulfonate is a surfactant derived from the reaction of linear alkenes (C10-13) with benzene to form alkyl benzene, which is then sulfonated and subsequently neutralized with a sodium solution.
Step-by-step Summary of Industrial Production Process:
- Alkylation. Linear alkenes (C10-13) are reacted with benzene to produce alkyl benzene.
- Sulfonation. The produced alkyl benzene is then sulfonated using a sulfonating agent like sulfuric acid or sulfur trioxide.
- Neutralization. The resulting alkyl benzene sulfonic acid is neutralized with a sodium solution to form the sodium salt of alkyl benzene sulfonic acid.
- Purification. The product is purified to remove impurities through processes such as distillation or filtration..
Form and Color.
It appears as a light to dark yellow viscous liquid or as a white solid depending on the form it's sold in.
What it is for and where
Cosmetics
Cleansing agent. Ingredient that cleanses skin without exploiting the surface-active properties that produce a lowering of the surface tension of the stratum corneum.
Surfactant - Cleansing agent. Cosmetic products used to cleanse the skin utilise the surface-active action that produces a lowering of the surface tension of the stratum corneum, facilitating the removal of dirt and impurities.
This substance is used in the following products: washing & cleaning products, cosmetics and personal care products, biocides (e.g. disinfectants, pest control products), non-metal-surface treatment products, polishes and waxes, air care products, metal surface treatment products, lubricants and greases, adhesives and sealants, perfumes and fragrances, textile treatment products and dyes, pharmaceuticals and leather treatment products. Other release to the environment of this substance is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), indoor use in long-life materials with high release rate (e.g. release from fabrics, textiles during washing, removal of indoor paints), outdoor use in long-life materials with high release rate (e.g. tyres, treated wooden products, treated textile and fabric, brake pads in trucks or cars, sanding of buildings (bridges, facades) or vehicles (ships)), indoor use in long-life materials with low release rate (e.g. flooring, furniture, toys, construction materials, curtains, foot-wear, leather products, paper and cardboard products, electronic equipment), outdoor use as processing aid and outdoor use in long-life materials with low release rate (e.g. metal, wooden and plastic construction and building materials) (1).
