Title:
疎水性変性糖類表面活性剤
Document Type and Number:
Japanese Patent JP2005504630
Kind Code:
A
Abstract:
The invention relates to the use as surfactant, for the preparation of dispersions of multiphase systems that comprise a continuous aqueous phase containing a high concentration of electrolytes, of hydrophobically modified saccharides of general formula (I) and (II) ÄAÜn(-M)s (I) ÄBÜm (-M)s' (II) wherein ÄAÜ n represents a fructan-type saccharide ÄBÜ m represents a starch-type saccharide (-M) represents a hydrophobic moiety that substitutes a hydrogen atom of a hydroxyl group of the fructosyl and/or glucosyl units of the fructan-type and starch-type saccharides, which is selected from the group consisting of an alkylcarbamoyl radical of formula R-NH-CO- and an alkylcarbonyl radical of formula R-CO- , wherein R represents a linear or branched, saturated or unsaturated alkyl group with from 4 to 32 carbon atoms, and s and s' , which can have the same value or not, represent the number of said hydrophobic moieties that substitute the fructosyl or glucosyl unit, expressed as average degree of substitution (av. DS) which ranges from 0.01 to 0.5. The invention also relates to a method for the preparation and/or stabilisation of dispersions of multiphase systems that comprise a continuous aqueous phase containing a high concentration of electrolytes, by using as surfactant one or more hydrophobically modified saccharides of general formula (I) and/or (II) defined above. Also dispersions of multiphase systems are disclosed that comprise a continuous aqueous phase containing a high concentration of electrolytes and that comprise as surfactant one or more hydrophobically modified saccharides of general formula (I) and/or (II) defined above.
