Abstract: Provided is a process for forming a dissolvable fiber, the process including (a) producing an extrudate from a twin screw extruder; and (b) forming the extrudate into the dissolvable fiber. The dissolvable fiber includes (i) from about 10% to about 60% of one or more anionic surfactants; (ii) from about 10% to about 50% of one or more water soluble polymers; (iii) from about 1% to about 30% of one or more plasticizers; and (iv) from about 0.01% to about 30% water. The one or more anionic surfactants have a Krafft point of less than about 30° C. The dissolvable fiber has an average diameter of from about 20 microns to about 1,000 microns.

Abstract: Provided is a personal care article including one or more extruded dissolvable fibers. The extruded dissolvable fibers include (a) from about 10% to about 60% of one or more anionic surfactants; (b) from about 10% to about 50% of one or more water soluble polymers; (c) from about 1% to about 30% of one or more plasticizers; and (d) from about 0.01% to about 30% water. The one or more anionic surfactants have a Krafft point of less than about 30° C. The one or more extruded dissolvable fibers has an average diameter of from about 20 microns to about 1,000 microns. The personal care article has a dry density of from about 0.02 g/cm3 to about 0.30 g/cm3.
