Anionic linear alkyl ar yl sulfonates LASs and long chain.
Linear alkylbenzene sulfonate. Alkylbenzene sulfonates are a class of anionic surfactants consisting of a hydrophilic sulfonate head-group and a hydrophobic alkylbenzene tail-group. Along with sodium laureth sulfate they are one of the oldest and most widely used synthetic detergents and may be found in numerous personal-care products soaps shampoos toothpaste etc and household-care products laundry detergent. Category Name Linear Alkylbenzene Sulfonate LAS Structural Formula This structure of a C12-LAS is representative of the category.
SUMMARY CONCLUSIONS OF THE SIAR Category Identification Justification The LAS molecule contains an aromatic ring sulfonated at the para position and attached to a linear alkyl chain at any position except the terminal carbons. The alkyl carbon chain typically has. Linear alkylbenzene is sulfonated to produce linear alkylbenzene sulfonate LAS a biodegradable surfactant.
LAS replaced branched dodecylbenzene sulfonates which were phased out because they biodegrade more slowly. In this study we investigated the degradation of linear alkylbenzene sulfonate LAS by an ultraviolethydrogen peroxide UVH 2 O 2 processIn a collimated beam experiment with UV light of wavelength 222 or 254 nm faster LAS degradation rates occurred at elevated H 2 O 2 concentrations. The degradation behavior varied with the wavelength of the light source.
In this market linear alkylbenzene sulfonate is the largest segment by product type whereas industrial cleaner is largest by application. Players can benefit from the available opportunities like increasing demand for cleaners and household detergents as well as for dishwashing cleaners. 26 Linear alkylbenzene sulfonate benzenesulfonic 27.

Linear alkylbenzene sulphonate LAS is an anionic surfactant. It was introduced in 1964 as the readily biodegradable replacement for highly branched alkylbenzene sulphonates ABS. LAS is a mixture of closely related isomers and homologues each containing an aromatic ring sulphonated at the para position and attached to a linear alkyl chain.

This requirement resulted from the fact that the original alkylbenzene sulfonate anionics were based on branched alkenes and these proved resistant to degradation by bacteria at sewage treatment works causing many rivers to suffer from foam. There was also a fear that surfactants could be recycled into drinking water.
Similar concerns were expressed about nonylphenol ethoxylates and so in.

Linear Alkylbenzene Sulfonate Structure 14 The linear alkylbenzene sulfonates LAS are quite abundant in detergents today as they are the component of detergents that help to best wet the fabric and lower the surface tension. The ideal range of carbons for the LAS to be good wetting agents is 9- 12 carbons and 15-18 carbons for ones that are good emulsifiers or good at lowering.

Shampoo is a basic hair care product representing the largest segment of hair care cosmetics. Shampoo is typically in the form of a viscous liquid with some exception of waterless solid form such as a bar.
Shampoo was developed to replace soap for cleansing scalp and hair by removing unwanted sebum dandruff environmental dust and residues of hair care products. The main surfactant used by the detergent industry is LAS Linear Alkylbenzene Sulfonate which is derived from crude oil and is ultimately biodegradable but not anaerobically biodegradable ie it will not biodegrade unless oxygen is present.
