Abstract
A process for forming a personal care article, the process including (a) adding one or more water soluble polymers and one or more plasticizers to a kneader to form a premix; (b) adding one or more anionic surfactants to the premix to form a mixture; (c) kneading the mixture until homogeneous; and (d) forming the personal care article. The personal care article 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 10% to about 50% water. The one or more anionic surfactants have a Krafft point of less than about 30° C.
