Abstract
The galacturonic acid derivatives of formula: ##STR1## R1 being a linear or branched alkyl having 2 to 22 carbon atoms, R being: ##STR2## for which the carbon carrying the hydroxyl group is attached to the endocyclic oxygen atom. R2 being hydrogen, R1, an alkali metal atom, an alkaline-earth metal atom or a quaternary ammonium group of formula: ##STR3## in which R3 to R6 is each independently of the other hydrogen, an alkyl having 1 to 6 carbon atoms or a hydroxyalkyl having 1 to 6 carbon atoms, are surface-active agents.
Claims8
A galacturonic acid derivative having the formula ##STR16## wherein R1 represents linear or branched alkyl having 8-22 carbon atoms, and
- R represents ##STR17## or ##STR18## wherein R2 is the same as R1 and wherein the carbon atom carrying the hydroxyl group is not attached to the endocyclic oxygen atom.
A process for imparting surfactant properties to a composition comprising incorporating into said composition from 0.1 to 60 percent by weight a derivative of the formula ##STR19## wherein R1 represents linear or branched alkyl having 8-22 carbon atoms and
- R represents ##STR20## wherein R2 is the same as R1 and wherein the carbon atom carrying the hydroxyl group is not attached to the endocyclic oxygen atom.
A detergent composition comprising 0.1 to 60 percent by weight of a detergent and 99.9 percent to 40 percent by weight of adjuvants, said detergent comprising a galacturonic acid derivative having the formula ##STR21## wherein R1 represents linear or branched alkyl having 8-22 carbon atoms, and
- R represents ##STR22## wherein R2 is the same as R1 and wherein the carbon atom carrying the hydroxyl group is not attached to the endocyclic oxygen group.
A cosmetic composition comprising 0.1 to 50 percent by weight of an active substance and 99.9 to 50 percent by weight of an excipient, said active substance comprising a galacturonic acid derivative having the formula ##STR23## R1 represents linear or branched alkyl having 8-22 carbon atoms, and ##STR24## wherein R2 is the same as R1 and wherein the carbon atom carrying the hydroxyl group is not attached to the endocyclic oxygen group.
