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.
