  • Publication number: 20240090497
    Abstract: Hypohalite-based disinfecting compositions are provided. The hypohalite-based disinfecting compositions comprise a source of chlorine, such as sodium hypochlorite, and a surfactant blend. The surfactant blend includes a first surfactant having a first surfactant surface tension T1 and a second surfactant having a second surfactant surface tension T2. The inventive disinfecting composition has an overall surface tension T that is less than the individual surfactant surface tensions T1 and T2, respectively.

  • Publication number: 20230354815
    Abstract: Sanitizing and disinfecting compositions with relatively low levels of free available chlorine, with good effectiveness against microbes. The composition may include less than 0.5% by weight hypochlorite or other free available chlorine level, at least one nonionic or zwitterionic surfactant, with a pH from 8 to 12.5. The composition is characterized by an R value of greater than 0 (e.g., greater than 0.5, or equal to 1), where R is defined as the sum of the concentration of any nonionic, zwitterionic, and cationic surfactants divided by the total surfactant concentration (and total surfactant concentration may include any surfactant aids). The compositions may exhibit at least a 3-log reduction in M. bovis or C. diff population within 10 minutes (e.g., 4-6 minutes).

  • Patent number: 10450536
    Abstract: The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ?3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.

  • Patent number: 10098503
    Abstract: A combustible charcoal igniting device may include first elongate grid members generally parallel to one another when the device is in an uncollapsed configuration and second elongate grid members generally parallel to one another and transverse relative to the first elongate grid members when the device is in the uncollapsed configuration. The first and second elongate grid members define chimney cells on or above which charcoal briquets may be placed for ignition. The elongate grid members may comprise a combustible material that can be ignited and that will continue to bum, igniting charcoal briquets placed on the chimney cells. The first elongate grid members may include creases that align with one another, so that the device is collapsible from opposed sides towards a crease line defined by the creases to reduce the length of the device when in a collapsed configuration.
