Abstract
A solid cleansing product including at least a first surfactant and a second surfactant present in a combined surfactant weight amount, both of the first and second surfactants being free of sulfate-containing materials; at least a first buffering agent and a second buffering agent a present in a combined buffering agent weight amount; where the combined buffering agent weight amount is at least double the combined surfactant weight amount.
Claims15
A solid cleansing product comprising:
- a. At least a first surfactant present in a first surfactant weight amount and at least a second surfactant present in a second surfactant weight amount, both of the first surfactant and the second surfactant being free of sulfate-containing materials, wherein the first surfactant weight amount and the second surfactant weight amount are approximately equal to each other, wherein the combined weight amount of the first surfactant and the second surfactant is about 16% to about 20% by weight of the solid cleansing product, and wherein the first surfactant is an isethionate and the second surfactant is a betaine;
- and
- b. At least a first buffering agent and at least a second buffering agent, wherein the first buffering agent and the second buffering agent are present in a combined buffering agent weight amount;
- Wherein the combined buffering agent weight amount is at least double the combined weight amount of the first surfactant and the second surfactant;
- and
- wherein the combined weight amount of the first and second surfactants and the first and second buffering agents is from about 60% to about 70% by weight of the solid cleansing product.

A solid cleansing product comprising:
- a. A first surfactant present in a first surfactant weight amount, a second surfactant present in a second surfactant weight amount, and a third surfactant present in a third surfactant weight amount, each of the first, second and third surfactants being free of sulfate-containing materials, wherein the first surfactant weight amount is approximately equal to the combined weight amount of the second surfactant and the third surfactant, wherein the second surfactant weight amount is approximately equal to the third surfactant weight amount, wherein the first surfactant is an isethionate, the second surfactant is a betaine, and the third surfactant is a taurate;
- and
- b. At least a first buffering agent and at least a second buffering agent, wherein the first buffering agent and the second buffering agent are present in a combined buffering agent weight amount;
- wherein the combined buffering agent weight amount is at least double the combined weight amount of the first surfactant and the second surfactant;
- and
- wherein the combined weight amount of the first, second and third surfactants and the first and second buffering agents is from about 60% to about 70% by weight of the solid cleansing product.
