Apart from the performance characteristics of alpha olefin sulfonates, such as foaming properties and mildness to the skin, its biodegradability boosts its use as an alternative to linear alkylbenzene sulfonates
in a variety of personal care products.
Further compounds found with high intensities in different covered areas of the needle shaft are: calcium oxides, calcium sulfate, fatty acids ([C.sub.n][H.sub.2n+j]COOH), alkyl sulfates ([C.sub.n][H.sub.2n+1]S[O.sup.-.sub.4]), alkylbenzene sulfonates ([C.sub.n][H.sub.2n+1][C.sub.6][H.sub.4]S[O.sup.-.sub.3]), toluene sulfonic acid (C[H.sub.3][C.sub.6][H.sub.4]S[O.sup.-.sub.3]), quaternary ammonium compounds (N[([C.sub.n][H.sub.2n+1]).sup.+.sub.4]) and formic acid.
sodium and calcium with high intensities as well as poly(dimethyl siloxane), different fatty acids, wax alcohols, alkylbenzene sulfonates and carboxylic acid salts like sodium soaps.
Linear alkylbenzene sulfonates and related compounds.
Linear alkylbenzene sulfonate (LAS) is an amphiphilic surfactant with a high solid-adsortion coefficient and readily adsorbs onto colloidal surfaces, suspended particles and solid substrates in water (Painter and Zabel 1989).
Alcohol ethoxylates, soap, linear alkylbenzene sulfonates
, alcohol sulfates and alcohol ethoxylates together account for more than 72% of the total consumed.
In a presentation on advances in alkyl benzene sulfonate surfactants, several researchers from Procter & Gamble, detailed the benefits of modified linear alkylbenzene sulfonates (MLAS).
In the Philippines, legislators enacted a law that bans "hard" surfactants (such as alkylbenzene sulfonate) and provides tax incentives for local businesses to switch manufacturing to naturally-derived alkyl sulfates from coconuts.
