    • Disclosed are glucoside alkyl urethanes composed of units of the formula: A(O—CO—NH—R)s wherein A represents a glucosyl unit of a starch hydrolysate moldecule, the starch hydrolysate having a Dextrose Equivalent (D.E.) ranging from 1 to 47, (O—CO—NH—R) represents an N-alkyl aminocarbonyloxy group replacing a hydroxyl group of the glucosyl unit A, and wherein R represents a linear or branched, saturated or unsaturated alkyl group containing from 3 to 22 carbon atoms, and s represents the number of alkyl carbamate groups per glucosyl unit which number is expressed as degree of substitution (DS) with said DS value ranging from about 0.01 to about 2.0 which are useful as surface-active agents. Also disclosed are a method for their manufacture and to compositions containing one or more glucoside alkyl urethanes. The glucoside alkyl urethanes have good to excellent tensio-active properties in combination with good biodegrability and they are suitable as surfactants for use in household and industrial applications, e.g., as detergents, emulsifiers, emulsion stabilisers, foaming agents, foam stabilisers, dispersants and wetting agents.

    • 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) [A]n(-M)s (I) [B]m(-M)s′ (II) wherein [A]n represents a fructan-type saccharide [B]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.
