The present invention relates to bars comprising soap bar matrix comprising predominantly long chain length soap and regions or domains interspersed within the matrix comprising predominantly shorter chain soaps. The novel bars of the invention are sufficiently hard to survive large scale manufacturing while simultaneously delivering benefits of significant foam value enhancement, for example, due to delivery of short-chain soaps from concentrated regions. Surprisingly, even when soaps in concentrated regions comprise small percentage of overall soap oils or fats used, they form observable kappa phase pattern.
