  • Publication number: 20230310304
    Abstract: An antibacterial composition comprises water, alcohol, a thickening agent, and a moisturizing oil, wherein at least 50% of droplets of the moisturizing oil present in the antibacterial composition have a particle size of 5 micrometers to 10 millimeters. A method of making an antibacterial composition comprises dispersing a thickening agent in water to form a first phase; combining a moisturizing oil and a humectant to form a second phase; combining the first phase with an alcohol to form a third phase; adding the second phase to the third phase, forming a fourth phase; and adding a neutralizer to the fourth phase, thereby forming the antibacterial composition.

  • Patent number: 8732887
    Abstract: A personal care implement is disclosed having a water insoluble absorbent/adsorbent layer attached to a water insoluble scrubbing layer and a mild, low active, low viscosity cleansing composition contained in the absorbent/adsorbent layer. A sufficient quantity of the composition is transferred on demand to the scrubbing layer by squeezing the implement. The implement produces copious quantities of lather foam and mild cleansing.
