US Patent No. 12,514,793 B2; Kenvue Brands LLC, Summit, NJ, patented cleansing compositions and methods for forming in situ complexation of surfactants providing controlled foaming and improved rinsibility of surfactants from skin or hair.

The composition details a first composition with 1-10% of a single anionic surfactant (wherein no other anionic surfactant is present in the first composition) and a second composition with a cationic surfactant.

The compositions are kept in separate containers and are individually dispensed as a foam. When the foams are combined, they form a cleansing composition with an initial foam volume of 3-8 mL. Ten seconds after that initial foam volume level, the volume of is less than 70% of the initial foam volume.

The cleansing system exhibits initial high foam volume, rich and creamy foaming effect, followed by quick foam breakage and ease of rinsing, while simultaneously providing moist conditioning with mild, sensorial touch and feel benefit to the skin. The cleansing system may optionally further include moisturizing or conditioning agents to provide enhanced moisturizing effect.
