  Compositions de savons. 



   La présente invention concerne des compositions de savons et plus particulièrement   l'utilisation de   certains alcanolamides pour disperser les sels calcaires insolubles qui se forment lorsque des savons solubles dans   l'eau sont   dissous dans de l'eau dure   Un inconvénient important des savons ordinaires est qu'ils forment dans l'eau dure un précipite déplaisant qui est   appelé habituellement "écume de savon calcaire". 



   Un but de la présente invention est de procurer des compositions de savons dont la tendance à former de l'écume de savon calcaire dans   l'eau   dure soit-faible ou nulle. 



    Un autre but de l'invention est de procurer des pains de savon.qui, utilisés dans de l'eau dure,résistent à la formation

  Soap compositions.



   The present invention relates to soap compositions and more particularly to the use of certain alkanolamides for dispersing insoluble limestone salts which form when water soluble soaps are dissolved in hard water. A significant drawback of ordinary soaps is that in hard water they form an unpleasant precipitate which is usually called "hard soap scum".



   An object of the present invention is to provide soap compositions which have either little or no tendency to form hard water scum in hard water.



    Another object of the invention is to provide bars of soap which, when used in hard water, resist formation.
