Recent findings and experiences with alpha olefin sulfonates

In the sulfonation and sulfation of alpha olefin (AO), linear alkylbenzene (LAB), and alcohol ethoxylate (AE), improved reaction yields and products’ color were obtained by using the TO-Reactor recently developed in Lion Fat & Oil Co., Ltd., compared with those obtained in a conventional falling-film type reactor. These improvements especially were remarkable in the case of AO, so that light-colored alpha olefin sulfonate (AOS), having improved performance properties, was obtained without bleaching. For the performance tests, AOS was evaluated in several systems, together with some other surfactants, alcohol sulfate (AS), alcohol ethoxy sulfate (AES), linear alkylbenzene sulfonate (LAS), and alpha-sulfo fatty acid methyl ester (a-SEMe). AOS was one of the most useful surfactants for heavy duty powder detergents of low phosphate formulation because of its good detergency and foaming power, rinsing property, and free flowing property. Thus, bright white heavy duty powder detergents, containing 8% of P₂O₅, were developed with AOS (nonbleached), AES, LAS, sodium pyrophosphate (TSPP), and some other ingredients, which have been marketed in the household cleaning products field in Japan since 1976.     

Precipitation of anionic surfactants in the presence of sodium oleate and calcium ions

Precipitation of anionic surfactants, linear alkylbenzene sulfonate (LAS) and alpha olefin sulfonate (AOS), by calcium ions was studied in the presence of sodium oleate. Lather stability was determined by the Ross-Miles method, precipitation was followed by measuring the optical density (OD), and equilibrium surface tension (EST) and Fourier transform infrared (FTIR) spectroscopy were used to characterize the nature of the precipitate formed. For the 5 mM LAS-0.7 mM oleate system, lather was unstable, and the OD was high in the 2–5°FH region of calcium hardness, while at higher calcium hardness levels, lather was stable and the turbidity of solutions decreased. On the other hand, in the 5 mM AOS-0.7 mM oleate system, lather was unstable throughout the calcium hardness region studied (0–20°FH). Also, the turbidity build-up was much higher in the AOS system than in the LAS system. Analysis of the precipitates formed in these systems by FTIR spectroscopy indicated that the precipitate from the AOS system had an additional band at 1190 cm⁻¹, corresponding to the sulfonate group. These results, together with the EST data, confirm that the precipitate formed in the LAS system between 2–5°FH calcium is calcium oleate, and that formed in the AOS system is likely to be calcium (AOS) oleate. It is tempting to hypothesize that the similarity of AOS and oleate in chainlength could be responsible for the coprecipitation of AOS and oleate with calcium, whereas LAS, which has a larger headgroup with a benzene ring and two smaller chains (average length is C8) is unlikely to precipitate with the oleate.     

New household detergent based on AOS

The synthetic detergent industry is one of the fastest growing industries in Japan. Its production, together with soap, is estimated to be almost 2 billion pounds in 1970. In addition to this increased production, quality modification in terms of biodegradability is now being undertaken. Alpha olefin sulfonate (AOS) has been known since the 1930’s, but only within the last two years has it been highlighted for commercial interest as a detergent material due to progress in sulfonation technology as well as commercial availability of alpha olefins. To make use of AOS as an active ingredient for formulation of heavy duty household granules, several properties of AOS itself or of the built detergent were studied in comparison with linear alkylate sulfonate (LAS), alkylbenzene sulfonate (ABS) and alcohol sulfate (AS). AOS was proved to be a potentially economical detergent material having as good performance and better biological properties than LAS or AS and better biodegradability than LAS. It has been marketed since 1967 in Japan as the first AOS-based household heavy duty granular detergent. It has been accepted by the housewives as the most efficient detergent and has become the best selling brand. Presented at the AOCS-AACC Joint Meeting, Washington, D.C., April 1, 1968.

Monitoring the linear alkylbenzene sulfonation process using high-temperature gas chromatography

Controlling the linear alkylbenzene sulfonate (LAS) sulfonation process is a critical part of the LAS manufacturing process; this process can be monitored by assaying for LAS content, unsulfonated linear alkylbenzene (LAB), and LAB sulfones. Traditionally, assaying the LAB and LAB sulfone contents has been time consuming and not straightforward. A simple and rapid procedure is described for the isolation and simultaneous capillary gas chromatographic (GC) quantification of LAB and LAB sulfones in LAS. The procedure involves extraction of the unsulfonated LAB and the LAB sulfones into n-heptane; sodium linear alkylbenzenesulfonate or linear alkylbenzenesulfonic acid (reacted to form sodium linear alkylbenzenesulfonate) remains in the aqueous extraction solvent layer. High-temperature capillary GC using a specialty metal capillary column enables both LAB and high molecular weight LAB sulfones to be quantified.

Detergency of binary mixtures of LAS/STPP and LAS/Zeolites: influence of (Ca++) on the washing liquor

The influence of sodium tripolyphosphate (STPP) or zeolites on the detergency performance of linear alkylbenzene sulfonate (LAS) has been evaluated at different water hardness levels. This study demonstrates that STPP or zeolite behaves either as a sequestrant or through an important synergism with LAS, showing a minimum and a maximum in detergency performance, depending on the water hardness level. There is an optimum LAS/builder ratio for each individual water hardness level. This optimum has to be determined experimentally as it will not always necessarily coincide with the highest surfactant and/or builder concentrations.     

Surface Activity,Aggregation, and Wetting Behavior of Sodium P-Perfluorononenyloxy Benzene Sulfonate

The physicochemical properties of sodium p-perfluorononenyloxy benzene sulfonate (OBS) in aqueous solution were investigated. Compared to linear alkylbenzene sulfonate (LAS), OBS has a lower critical micelle concentration (CMC) and a low surface tension at the CMC. At the same concentration, OBS shows lower dynamic surface tension than LAS indicating faster wetting kinetics. In aqueous solution, OBS forms large spherical vesicles above the CMC. OBS shows excellent dynamic wetting properties on low-energy surfaces. The superior properties of OBS make it ideal for use in many industry fields.
