Abstract:
1. Process of preparing an external structuring system for liquid and gel-form detergents comprising steps of: i) preparing a premix by adding about 5% to about 50% by weight of the external structuring system of anionic surfactant into water and mixing; ii) neutralising premix of step i) to pH 7.0-7.6 by adding pH adjusting agent at temperature between about 87° C. and about 95° C. and mixing; iii) adding about 2% to about 10% by weight of the external structuring system of crystals of a glyceride having melting point of from about 40° C. to about 100° C. and mixing; iv) emulsification by mixing of the premixture of steps i)-iii); v) cooling the emulsification of step iv) down to a temperature between about 25° C. and about 45° C. under controlled cooling rate of about 1 to about 2° C./min; characterized in that from about 0.5% to about 3.0% by weight of the external structuring system of packing parameter adjusting agent is added into said premix prior to the point where said crystals of a glyceride start to crystallize.
