Abstract
A method for manufacturing a water-soluble laundry detergent sheet from a liquid composition including the following components: (a) at least one textile stiffening agent, (b) at least one surfactant, (c) at least one water-soluble polymer, (d) at least one cellulase, (e) optionally at least one perfume component, and (f) optionally at least one adjunct detergent ingredient. Also encompassed are the water-soluble laundry detergent sheets obtainable by the method and the use thereof for cleaning textiles and in methods for cleaning textiles.
Claims14
A method for manufacturing a water-soluble laundry detergent sheet, the method consisting of the steps:
- (i) providing an aqueous liquid composition comprising:
- (a) at least one textile stiffening agent,
- (b) at least one surfactant,
- (c) at least one water-soluble polymer,
- (d) at least one cellulase,
- (e) optionally at least one perfume component, and
- (f) optionally at least one adjunct detergent ingredient;
- wherein the aqueous liquid composition does not contain starch;
- (ii) applying the composition of step (i) onto a moving surface rotating about a horizontal axis such that it forms a layer on said surface as the surface rises in a rising direction from contact with the composition, optionally allowing excess composition to drain off the rising surface in a direction opposite the rising direction, and optionally said surface is heated;
- (iii) drying said layer on the moving surface to obtain a laundry detergent sheet;
- and
- (iv) optionally cutting the laundry detergent sheet into pieces of a desired shape and size;
- and
- (v) optionally packaging one or more laundry detergent sheets obtained in step (iv).
