Definitions

• the invention relates to a shaped Syndet soap composition with a content of at least 50% by weight of synthetic surfactants and at least 10% by weight of non-surfactant auxiliaries.
• acyl isethionates obtainable by esterification of fatty acids with the salts of 2-hydroxyethanesulfonic acids (isethionic acid) have long been known as components of such Syndet soap compositions.
• the low plasticity of these surfactants causes considerable problems when processing them into shaped products.
• the foam behavior of the acyl isethionates is unsatisfactory, they have a low foam consistency and a poor foaming behavior. There has therefore been no lack of attempts to improve the processing and application properties of the acyl isethionates by additives and to make them more suitable for the production of shaped Syndet soaps.
• Alkyl (oligo) glycosides have already been described several times as components in bar soaps based on fatty acid soap, for example in DE-A-43 37 031 and DE-A-43 31 297. Their use in soap compositions based on alkyl sulfates and Sulfosuccinic acid ester salts is from G. Proserpio and G. Vianello in Rivista Italiana Essenze Profumi ... (1974), No. 10, page 571-

• the degree of oligomerization is a static mean value which is based on a homolog distribution customary for such technical products. (The average degree of oligomerization results from the molar proportions of the individual oligomers by dividing the sum of the structural units by the sum of the molecules).
