The Dissolvable Solid Structure as described herein can be in the form of a fibrous structure comprising: (a) a polymeric structurant; (b) a high melting point fatty compound such as a fatty amphiphile, and (c) a cationic surfactant. The polymeric structurant has a weight average molecular weight of from about 10,000 to about 6,000,000 g/mol, and the components of the fibrous material form a homogenous material when molten. When water is added to the dissolvable solid structure at a ratio of about 5:1 a lamellar structure is formed.
